which extends from the anterior margin to the outer angle of 

 the coxal cavity. The prothorax is minutely and sparsely 

 punctured on the disk ; the transverse grooves are very in- 

 distinct^ and there is just behind the middle a very faint and 

 feebly biiid process. The elytra are minutely and rather 

 sparsely granular at the base, the remainder being very mi- 

 nutely and sparsely punctate. They are of a light grey 

 colour, with a basal, triangular, more or less dark brown 

 patch, which is less distinct than the lateral markings ; these 

 consist of a subsemicircular marginal patch near the middle of 

 each and a much smaller spot towards the apex, botli dark 

 brown and velvety in appearance. The large lateral patch is 

 bordered along its anterior inner side with white, and has a 

 white spot in its middle close to the outer margin. The first 

 six joints of the antennse are in both sexes shortly fringed 

 with hairs on the underside, and the first three or four joints 

 in the male are slightly rugose. The anterior tibise in the 

 male armed towards their tarsal extremity with a strong 

 tooth, and the anterior tarsi fringed with black hairs. The 

 mesosternal process feebly tubercled in the middle. The 

 prosternal process * with its sides parallel, its posterior extre- 

 mity arcuate. Though that portion of the scape which bears 

 the cicatrice is, in the male, angularly produced on its inner 

 ventral side — a character of the genus Arckidice — the species 

 must be associated with Leprodera {Lamia) crucifera^ Fabr., 

 with which it has very strong affinities and in which the scape 

 is not so produced. 



The last-mentioned species — Phryneta crucifera^ Fabr., of 

 the Munich Catalogue — was placed by Von Harold in the 

 genus Leprodera and a doubtful habitat attributed to it, viz. 

 Ins. Bourbon. Of the five specimens in our Museum collec- 

 tion four are from Ceylon and one from Pondicherry. 



* I think it well to note this character of the prosternum, because in 

 one species at least of the genus Leprodera the form is different. In L. 

 verrucosa, Pasc, the prosternal process is angularly dilated on each side a 

 little behind its middle, the angles fitting into a corresponding notch or 

 depression in each coxa. This form of prosternum is, I find, constant in 

 the following genera of Monohammids -.^Pelargoderus, JEpepeotes, Dio- 

 chares, Mecotagus, Ptychodes, and Tceniotes. In Tceniotes it is most strongly- 

 marked, each angle at the sides of the prosternal process fitting, in some 

 cases, into a kind of sheathing-notch in the coxae. 



It is probable that the same form of prosternum which is found in 

 verrucosa occurs also in L. elongata, Thorns., and L. equestris, Pasc. ; it is, 

 in fact, doubtful whether these two species are not identical and whether 

 they are not both females of verrucosa. If this is so, it may become 

 necessary to dissociate most of the remaining species of the genus from 

 the type L. eJongata,
