246 INSECTA. 



heaps up the bodies of various dipterous Insects, particularly 

 Syrphi and Muscae, and lays her eggs ; she then closes the 

 opening with earth. Throughout Europe *. 

 Sometimes the maxillary palpi, which are tolerably elongated, 

 consist of six joints, and the labials of four, as in 



MONEDULA, Lat. t 



The others have no false proboscis, and the labrum is short and 

 rounded. Such is 



Stizus, Lat. Jur.\ 



5. Other Fossores, having nearly the same appearance as those 

 of the preceding divivion, differ from them in the labrum, which is 

 either totally or partially hidden ; their mandibles present a deep 

 notch in their interior side near their base, a character which distin- 

 guishes them both from the preceding and following Insects. They 

 are ourLARRAXES. 



Here the superior wings have three closed cubital cells, the second 

 of which receives the two recurrent nervures. 



Palarus, Lat. — Gonius, Jur., 

 Where the antennae are A'^ery short and gradually enlarge ; the eyes 

 are closely approximated posteriorly, and enclose the ocelli; the 

 second cubital cell is petiolate §, 



Lyrops, Illig. — LiRis, Fah. — Larra, Jur., 

 Where the antennae are filiform, where the third cubital cell is nar- 

 row, oblique, almost lunate, and the inner side of the mandibles offers 

 a dentiform projection ||. 



Larra, Fab., 

 Hardly differs from Lyrops except in the absence of teeth on the 

 inner side of the mandibles, the equal distance between the eyes, and 

 the evidently longer metathorax and abdomen % 



Thei-e, the superior wings have but two closed cubital cells, each 

 of which receives a recurrent nervure. 



DiNETus, Jur., 

 Where the two cubital cells are sessile. The antennae of the males 

 are moniliform inferiorly, and then filiform. The mandibles are 

 tridentated on the inner side, and the radial cell is fui'nished with an 

 appendix **. 



MiscoPHUs, Jur., 

 Where the second cubital cell is petiolate and the radial offers no ap-
