 APRIL — JUNE 1857.] Descriptions of new Ceylon Cohopieva. 63

are unconnected amongst themselves, their edges are entire and and they attain their highest development at the apex of the 4th joint, in fact their development is gradual from the base of the 1st joint to the apex of the 4th. The intermediate tarsi, although not di- lated, are similarly provided as the anter. ones, but only at the apex of the 2nd and at the Si'd and 4th joint, the squamulae being of rather a square shape, triangularly prolonged anil peduncled at the base ; the 1st joint is naked in this pair.

The tarsi of the female are very much the same as those of the male, excepting, the 4th joint which, as above mentioned, is bifid. A further distinction exists, however, in the squamulse. In the 2 ant. tarsi of the female these are present at the apex only of the 1st and 2nd joint (hardly distinct at the former) ; however, they are well developed in the 3rd and very highly in the 4th joint, the squamulaceous bristles are less conspicuous but the peduncle at- tains extraordinary length in the 4th joint, the squamulae do not cover each other like tiles but stand more freely and loosely and are curved inward so as nearly to touch in the middle, their shape is that of an elongated triangle, they are veined and their apical edge is serrated. Being such and placed upon long, slender, pedun- cles they forcibly remind me of the leaflets of certain ferns (Adian- tum) and hence the specific name foliolosa. The intermediate tarsi are similarly provided, but, as in the male, the 1st joint is naked and the 2nd furnished at the apex only. The lower edges of the 2 posterior tarsi are very neatly fenced in with small closely set spines.

I feel doubtful as to the affinities of these insects, especially if in reality I have described both sexes and if the vesture of the inter- mediate tarsi is allowed to be of the same importance as that of the anterior ones, however, I think they must find a place amongst the Harpalid^ as restricted by Lacordaire. I must not omit to men- tion that the tooth of the mentunj appears to be variably, one of my specimens (a male) being decidedly without it, whilst another is furnished with a small, obtuse one.
