370 Dr. F. Meinert on the Campodee, 
placed under the suture in the middle, and bifureates near the 
centre of the head, the two branches approaching the lateral 
margin of the head. 
The three thorax-rings are well separated by double folds ; 
and as some of these are chitinized both on the dorsal and the 
ventral surface, we observe in the prothorax a presternum and 
poststernum, in the mesothorax a pretergum as well as preester- 
num and poststernum, and in the metathorax both pratergum 
and presternum. 
The legs are slender, with small conical coxee ; they are rather 
abundantly furnished with stiff hairs, particularly the feet, which 
articulate with the tibie by means of regular condyles, and 
which in length stand between the femora and the tibie. The 
claws are large, foliaceous, but of unequal length. The em- 
_ podium is well developed and supported by a thin curved chi- 
tinous piece; between the claws there is a small cultelliform 
onychium, which might be described as a third claw, if such a 
thing was at all possible or reconcileable with the symmetry of 
the insect body*. The proportionate lengths of the two claws 
and the onychium are as 3 to 2 to 1, or, more correctly, as 
15 to 10 to 4. 
The moveable appendages on the underside of the first seven 
abdominal rings are in this genus (or, at any rate, in the only 
species as yet discovered) reduced to very short conical bristles, 
each bearing a fine hair on its side, and articulated with the 
ventral shield near its posterior corners. The first of these 
rings, the segmentum mediale, is, besides, distinguished by a 
small protruding wart, with five or six rows of impressed points 
bearing sete peeping out from behind the middle of the’ poste- 
rior margin of its ventral shield; on each side of this wart there 
is a smaller flat protuberance furnished with rather longer bristles. 
The ventral and dorsal shields of all these seven rings cover 
almost the whole of their upper and under surface, whilst the 
sides only in part are covered by small pleural plates. 
The three following rings are more closely united and more 
completely chitinized than any other part of the animal; but 
they are without the appendages described in the preceding 
rings. 
The sexual orifice rests on the posterior margin of the ventral 
shield of the eighth ring, and the deeply bifid vagina of the 
female can be protruded from behind the latter. The next ring 
(ninth) is very short, and its ventral shield is divided into two 
perfectly separate triangular plates. The last ring is longer and 
* Nor have the very young larve of Meloé been correctly described ‘ 
as possessing three claws (whence the name Triungulinus); they have m 
reality but one deeply trifid claw.
