2(3). Black, unicolorous ; shoulders of elytra 



dentate jdatynotics, Bates. 



3 (2). Black, with ferru<;inous wattern on elytra ; 



shoulders of elytni not aeutate rubropictus, Sloane. 



4 (1). Prothorax bur iered throu<,^hout, except over 



middle third of front iuarj>iu, and between 

 the badal sulci ; surface punctate at sides 

 of base, elytra black, with testaceous 

 pattern, shoulders not dentate piclurattis m. 



Cosiiiodiscus platynotus, Bates. 



Length 6-8 mm. 



Prothorax much more narrowed in front than the descrip- 

 tion indicates. Tlieve is a border along both front and side 

 n)argins, but none along basal margin. As in the other 

 .species the surface is a little flattened out near hind angles. 

 There are a few punctures in the basal t'oveoe, and the mar- 

 ginal channel at sides is also irregularly punctate, but the 

 surface is otherwise quite smooth. The elytra are very shorty 

 hardly Avider than the prothorax ; the basal border is j)ro- 

 duced at the shoulder and forms a small but distinct tooth. 

 On the underside, the prothoracic epipleurie are very wide, 

 and the intercoxal process is unbordered or bordered at 

 extremity only ; the mesepisterna, sides of metasteruum, 

 nic-tepisterua, and sides of ventral surface are all coarsely 

 punctate. 



Cosmodiscus pictitratnft, sp. ii. 



Length 6-0-G'5 mm.; width 2 ()0-2-75 mm. 



Black, shiny ; border of prutliorax and elytra, under 

 suifac e of head, sterna, apex of vential surface, tibia?, tarsi, 

 and joints 1-3 of antenme ferruginous; rest of legs and an 

 elytral j)attern testaceous. The olytral pattern consists of: 

 (1) a slightly oblique streak on the shoulder, covering 

 approximately intervals 5-8 at base, and terminating on 

 interval G about halfway towards apex ; (2) a horseshoe- 

 shaped maik, commencing at three-hfths from base and 

 convex towards apex, interrupted on sutural intervals, the 

 front part on intervals 4-5, the hind part on 2-3, the colour 

 on these last oxtoiuling a little towards apex ; (3) a short 

 oblique streak, close to apex, on intervals 7-8. (In the type 

 and Oxford specimens the elytral pattern is light in colour and 

 well develoj)ed ; in all the others the marking?:, which are 

 rather daiker, are more or less evanescent, disapj)earing in 

 some exanq^les on the shoulder and in others near the apex.)
