in the four anterior ones ; joint 5 is large, and the claws strong 

 and simple ; a membranaceous process of triangular form covers 

 the base of the latter above. 



The internal vesture of the four anterior tarsi of the male is 

 of the following description. The inner part of joints 1-4 of the 

 two anterior ones is furnished with two longitudinal series of 

 pedunculate squamulse_, which are of a broad triangular form, and 

 lie like tiles upon each 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 ai'c entire, and they attain their highest 

 development at the apex of the fourth joint ; in fact, their deve- 

 lopment is gradual, from the base of the first joint to the apex 

 of the fourth. The intermediate tarsi, although not dilated, are 

 similarly provided with the anterior ones, but only at the apex of 

 the second and at the third and fourth joints, the squamulse 

 being of rather a square shape triangularly prolonged and 

 pedunculate at the base; the first joint is naked in this pair. 



The tarsi of the female are very much the same as those of the 

 male, excepting the fourth joint, which, as above mentioned, is 

 bifid. A further distinction exists, however, in the squamulae. 

 In the two anterior tarsi of the female these are present at the 

 apex only of the first and second joints (hardly distinct at the 

 former) ; however, they are well developed in the third, and very 

 highly in the fourth joint ; the squamulaceous bristles are less 

 conspicuous, but the peduncle attains extraordinary length in 

 the fourth 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 ¥evi[is{Adiantum) , 

 and hence the specific name foliolosa. The intermediate tarsi 

 are similarly provided, but, as in the male, the first joint is 

 naked, and the second furnished with scales at the apex only. 

 The lower edges of the two 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 variable, one of my specimens (a male) being decidedly 

 without it, whilst another is furnished with a small, obtuse one.
