Structure soft, fragile. Head witli the Chjpeus developed. 

 AntenncB 4-jointed, mostly setiform or filiform, often very long, in- 

 serted for the most part between and before the eyes. Ocelli 0.* 

 ^os^rwm 4-jointed, free. Elytra: Cot'ium with. a Oimeus ; Membrane 

 with two closed cells at its base, more rarely with only one, otherwise 

 without nerves. Tarsi trimerous. 



Abdomen,. — lu the $ there are apparently seven abdominal segments, 

 but the seventh is the first genital segment, which has entirely the form of an 

 abdominal segment. In the 9, on the underside, the six abdominal seg- 

 ments Jiave their posterior margin either straight or the last two or three 

 raised and retracted in the middle, the sixth often so much that it is only 

 visible on the sides ; usually the posterior margin of the last, or, when the 

 middle of it cannot be seen, then of the penultimate segment, has a short, 

 triangular process, overlying the base of the ovipositor, but this is some- 

 times wanting. The genital segments are formed alike in all the genera. 

 In the $ the first of the two, as before stated, has entu-ely the form of 

 the preceding abdominal segment ; the second, or true genital segment, is 

 large, visible above and beneath, somewhat convex beneath, gradually 

 tapering to the apex, with an opening above for the anus and genital 

 organs. In the $ the second and third segments are visible above and 

 beneath, annular, and formed like the preceding abdominal segments, but 

 on the underside cleft in the middle throughout their length, the margins 

 of the cleft being parallel to each other. The second segment beneath 

 has its posterior margin straight or a little concave, anteriorly widely 

 extended, the angles which lie on the cleft rounded ; the third segment 



* Kolenati, in his ' Meletemata Entomologica,' fasc. ii, p. 95, says, " Ocelh 

 minimi ;" and adds, " Sub microscopio pro corporibus opacis constructo ocehi 

 pone et retro oculos couspici possuut. Ocelli in Capsinis numquam nigri a me 

 visi; semper enim pellucidi, hinc in capite pallido difScillimi visu. Facilius 

 conspiciendi in lamella epicranii a reliquis capitis partibus separata."
