OsDAEA [Helopidae].

Osdara Icevicollis. 



O. capite prothoraceque nigris, Isevibus; elytris subferrugineis^ nigro 

 tuberculatis ; pedibus rufo-ferrugineis. 



Hab. Ceylon. 



Ovate, convex ; bead and protborax smootb, glossy black, very finely 

 punctured ; scutelluni small, triangular ; elytra pale ferruginous with a 

 tinge of grey, covered vritb irregular lines of black tubercles wliicli, 

 under the lens, are seen to be composed of smaller ones (from 2-10)^; 

 amongst these, in the intervals, a few deeply impressed punctures j legs 

 bright reddish-feiTuginous, anterior and intermediate tibi?e with a small 

 rounded tooth near the extremity internally ; antennae at the base and 

 palpi ferruginous; body beneath dark brown, coarsely punctured. Length 

 4 lines. 



This very interesting and distinct species agrees generically, ex- 

 cept as regards the mouth, which has not been examined, with 0. 

 picipes, save in the toothed tibiae, which in this instance can only be 

 considered of secondary importance. Both species have more or 

 less of a gloss, which has the appearance of being due to varnish ; 

 the black shining prothorax of the present, however, contrasted 

 with the elytra, is very marked, and recalls many Adesmice, to which 

 also it is very similar in form. A single specimen sent by Mr. 

 Thwaites from Ceylon is in my collection. 



OzoTYPTjs [Helopidae]. 



Characters nearly as in Osdara, Walker*, but differs in the epi- 

 stome not being separated from the front by any groove, by the 

 absence of the scutellum, by the form of the tibiae, wliich are fusi- 

 form and attenuated most at the extremity, and by the shortness of 

 the tarsi, the claw-joint being as long as the rest together. As 

 secondary characters, the form is narrower and more convex, the 

 antennae shorter, and the prothorax gibbons anteriorly. As in 

 Osdara, the prosternum has a sharp-keeled process which is received 

 into a corresponding notch of the mcsosternnm, and the intercoxal 

 plate is broad and rounded anteriorly. The same varnished appear- 

 ance is also as noticeable, but only on the elytra. In Ozotypus the 

 tubercles which cover the upper surface are smaller, more regularly 

 arranged, and each tipped with a short curved hair, which is not the 

 case in Osdara. In both genera the tarsi are all nearly of equal
