. The animal kingdom, arranged after its organization, forming a natural history of animals, and an introduction to comparative anatomy. Zoology. DIPT Eli A. 61J behind, the space between them being very ample, and divided by a longitudinal impression in the middle. The posterior extremity of the metathorax is prolonged into a large Bcutellum over the abdomen. These insects live in the larva state between the scales of the abdomen of some Andrenae and Wasps, belonging to the subgenus Polistes. They move their prebalancers at the same time as their wings. Although apparently far removed, in many respects, from the Hymen- optera, I nevertheless consider them nearest allied to some of these insects, such as the Eulophi. M. Peck has observed the larva- of Xenos Peckii, which is found in Wasps ; it is oval-oblong, without feet, annulated, with the anterior extremity ddated into a head, and the mouth formed of three tubercles. These larvae are transformed to pupae in the same situation, and beneath their own skin, as it appears to me from an ex- amination of Xenos Russii, and without changing its form. (See the memoir of M. Jurine upon this insect.) Probably the two prebalancers are ser- viceable in enabling the insect to disengage itseli from between the scales of the abdomen of the in- sects in which they have lived. They are a kind of (Estri of insects. We shall subsequently see that a species of Conops under- goes its changes in the interior of the abdomen o' Bombi. They compose [four genera] Xmos, Rosai; Slylops, Kirby [and Elenchus and Halictophagua, Curtis]. They chiefly vary in the form of the antenna:.
