.Mr. G. 0. Champion, who was good enough to affoi-J me. the 

 opportunity of examining them. ; 



ii The superficial resemblance between D. g^stroi and D. sasthi is 

 !so remarkable that they were considered as the same species. The 

 structural differences between them are considerable, and warrnnt 

 the erection of a new species. The close association of these two 

 structurally different forms, but possessing a sti-ong superdcial 

 resemblance, in the same food-plant is intei-esting, and is sugges- 

 tive of some form of mimicry. D. cei/lonica Maulik, J), rotana 

 Maulik, and D. kanare7isiifW else have also similar coloration^of the 

 elytra, viz. the apical portion is black while the basal is brown. 



Kari, gen. noy. 



This genus is erected for the insect of which a detailed 

 description is given below, according to the following characters : 

 (1) the shape of the body, parallel-sided, rounded posteriorly, the 

 pronotum transversely elliptical ; (2) the structixre of the antennse, 

 which partly lie in the channel on each side of the cavity in which 

 the head is imbedded ; (3) the peculiar structure of the tarsus, 

 in which there is no felt covering on the underside, and the 

 deeply bilobed charactei*, especially of the thiid joint, is absent. 

 The structure of the tarsi suggests that they have been adapted 

 to a desert life. The drab colour of the insect seems to support 

 this view. At present there are no data available with regard to 

 the larva) and tlie bionomics of the insect. By the shape of the 

 body and the antennal channels it is related to the genus Glypho- 

 casis, but the structure of the tarsus places this genus in a unique 

 position. 



Kari brunnea, sp. n. 



Body oblong, parallel- sided, rounded posteriorly; the front of 

 the pronotum slightly drawn forwards ; in profile tlie dorsal side 

 of the insect has a slight elevation posteriorly. Colour dull 

 brown ; the posterior undulated edge of the pronotum opposing the 

 anterior similarly undulated edge of the elytra, black; the eyes, 

 moiithparts, and the five apical joints of the antenna} black or 

 piceous. 



Head imbedded in' a hollow, each side of which forms a channel 

 in which lie the six basal joints of the antennae. The clypens flat, 

 indented with large coarse pits, some of which ai-e confluent with 

 each other and bear a few erect haii'S. The antonnje pass just 

 beyond the base of the pi-othorax on the underside, the first joint 

 thickened, club-shaped; the second small,- rounded ; the tliiid 

 longer than the fourth, which is equal in length to the fifth ; the 

 sixth slightly shorter than the fifth ; seventh to eleventh joints 

 form an elongated thickened club. The whole antenna is sparsely 

 covered with short, erect, whitish hairs. Froihorax transversely 

 oval, broader than long, as broad at the base as the el3tra ; the 

 middle of the slightly drawn out front edge with a very shallow
