other covering the sole of the tarsus ; they are flanked by bristles 

 which partake of the nature of scales, being dilated in the shape of 

 a lancet. These squamulse are without any particular colour, they 

 are unconnected amongst themselves, their edges are entire 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 dilated, 

 are similarly provided as the anter. ones, but only at the apex of 

 the 2nd and at the 3rd and 4th joint, the squamulse being of rather 

 a square shape triangularly prolonged and 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 

 attains extraordinary length in the 4th joint ; the squamulse do 

 not cover each other like tiles, but stand more freely and loosely 

 and are curved inwards 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, 

 peduncles they forcibly remind me of the leaflets of certain ferns 

 (Adiantum) 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 

 intermediate 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 Harpalidse as restricted by Lacordaire. I must not 

 omit to mention that the tooth of the mentum appears to be vari- 

 able, one of my specimens (a male) being decidedly without it, 

 whilst another is furnished with a small, obtuse one.
