2 (8). Black, unicolorous; shoulders of elytra 
dentate; Simian ne - eae ee o's gee ore Emon « platynotus, Bates. 
3 (2). Black, with ferruginous pattern on elytra ; 
shoulders of elytra not dentate ........ rubropietus, Sloane. 
4 (1). Prothorax bordered throughout, except over 
middle third of front margin, and between 
the basal sulci; surface punctate at sides 
of base, elytra black, with testaceous 
pattern, shoulders not dentate.......... picluratus m. 
Cosmodiscus platynotus, Bates. 
Length 6-8 mm. 
Prothorax much more narrowed in front than the descrip- 
tion indicates. There is a border along both front and side 
margins, 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 fovese, and the mar- 
ginal channel at sides is also irregularly punctate, but the 
surface is otherwise quite smooth. ‘The elytra are very short, 
hardly wider than the prothorax; the basal border is pro- 
duced at the shoulder and forms a small but distinct tooth. 
On the underside, the prothoracic epipleures are very wide, 
and the intercoxal process is unbordered or bordered at 
extremity only; the mesepisterna, sides of metasternum, 
metepisterna, and sides of ventral surface are all coarsely 
punctate, 
Cosmodiscus picturatus, sp. n. 
Length 6:0-6°5 mm.; width 2°60-2:75 mm. 
Black, shiny; border of prothorax and elytra, under 
surface of head, sterna, apex of ventral surface, tibia, tarsi, 
and joints 1-3 of antennz ferruginous; rest of legs and an 
elytral pattern testaceous. The elytral pattern consists of : 
(1) a slightly oblique streak on the shoulder, covering 
approximately intervals 5-8 at base, and terminating on 
interval 6 about halfway towards apex ; (2) a horseshoe- 
shaped mark, commencing at three-fifths from base and 
convex towards apex, interrupted on sutural intervals, the 
front part on intervals 4-5, the hind part on 2-8, the colour 
on these last extending 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 developed ; in all the others the markings, which are 
rather darker, are more or less evanescent, disappearing in 
some examples on the shoulder and in others near the apex.) 
Head (about 1°30 mm. wide) convex, smooth, shiny,
