Sleeping Habits Of Certain Hymenoptera, Nathan Banks
Sleeping Habits Of Certain Hymenoptera, Nathan Banks
An
The various means by which insects rest have been but little investigated. Occasional notes have been published, but often in connection with other matter, so that it is extremely difficult to collate the recorded facts. Since the Hymenoptera are among the most assiduous, as well as the most intelligent workers, it is natural that they should exhibit some interesting habits of sleep. The idea that the bee sleeps in the flower seems to have invaded literature at an early date. And there are a number of bees that commonly do remain in flowers (such as those of cucurbits and campanulas) …
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.10, William H. Ashmead
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.10, William H. Ashmead
An
The globose or rounded head, which is never flat, oblong, and the difference in the antennae, the antennae in males being 10-jointed, in the females 13-jointed, readily separate the subfamily from the Bethylinre. The group comes quite close to the Dryininae, but in the latter the head is transverse or subquadrate, never rounded, while the antennae are 10-jointed in both sexes.
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.9, William H. Ashmead
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.9, William H. Ashmead
An
This family was first defined by that astute British systematist, A. H. Haliday, who, as early as 1839, very correctly placed the family among the Fossores.

Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.8, William H. Ashmead
An
Prof. Westwood and others confused these wasps with the Vespidae and the Eumenidae, although Latreille had years previously established his family Masarides. Henry de Saussure, in his "Etudes," treats them as a tribe. They, however, represent a distinct family close to the Eurnenidae, but easily separated from them and the Vespidae by the wings not being folded longitudinally, by peculiarities of the antennae, which are usually strongly clavate at tip; by the wholly different abdomen, the venter being flatter; and by the much larger scutellum.
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.7, William H. Ashmead
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.7, William H. Ashmead
An
To this family belong the potter wasps. They differ from the paper-making wasps in being solitary and in constructing their nests of mud or clay, instead of macerated woody fibre or pulp. It is perhaps one of the largest, if not the largest, families in the Vespoidea, and is well represented in all parts of the world by many genera and species.
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.6, William H. Ashmead
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.6, William H. Ashmead
An
This family is restricted to the paper-making wasps, all social species living in large communities and having three distinct sexes, female, worker, and male, thus agreeing with the social bees, the Apidea and Bombidae, and with many ants, Dorylidae, Myrmicidae, Formicidae, etc.
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.5, William H. Ashmead
Classification Of The Fossorial, Predateous And Parasitic Wasps, Or The Superfamily Vespoidea No.5, William H. Ashmead
An
This subfamily comes nearest to the Aporinae, and a few of the males are easily confused with and mistaken for some males in the latter group.
Papers From The Harriman Alaska Expedition, William Harris Ashmead
Papers From The Harriman Alaska Expedition, William Harris Ashmead
An
In this paper 335 species are recorded, of which number 201 are regarded as new to science and are here first described. Of the 10 superfamilies, into which the order is now divided, all are represented in Alaska and are distributed into 29 families and 183 genera. Two of these genera, Dallatorrea and Hyposyntactus are new, and of the remainder, thirty have not been previously reported from North America.
