Gempylodes macer. (Pl. VIII. fig. 2.) 
G. rufo-brunneus ; prothorace vage punctato, latissime sulcato. 
Hab. Batchian. 
Rufous brown, clearer on the elytra except towards the apex; head 
rather finely punctured, the side reflected upwards over the insertion 
of the antenne; eyes rather prominent, transversely oblong, entire; 
antenne slightly compressed, 11-jointed, the basal joint short, thick, 
the second shorter but less robust, the third twice as long as the 
second, the fourth to the tenth gradually becoming shorter and more 
and more transverse, the eleventh broadly subovate; prothorax about 
twice and a half as long as broad, rather loosely punctured, a broad 
groove extending longitudinally the whole length, but rather narrower 
anteriorly ; scutellum punctiform; elytra strongly ribbed, the intervals 
with two rows of large, deeply impressed punctures, but in the sutural 
interval one row only; body beneath yellowish ferruginous, with small 
distant punctures on the propectus, coarser on the abdomen, basal 
segment with a strong longitudinal keel; antennee brown; legs fer- 
ruginous. Length 22 lines. 
The Siam Gempylodes mentioned above, besides many other cha- 
racters, has only a very narrow impressed line on the prothorax. 
Ocholissa humeralis. 
O. atra, nitida, macula humerali crocea; antennis tarsisque ferrugineis. 
Hab. Saylee; Morty; Mysol; Batchian. 
Black, shining; head rather rounded anteriorly, moderately punc- 
tured; prothorax nearly quadrate, rather distantly punctured; scu- 
tellum broadly transverse; elytra not broader than the prothorax, 
seriate-punctate, a large dark-yellow spot on each shoulder; body 
beneath dark brown, shining, remotely punctured; legs dark ferru- 
ginous brown, the tarsi and antenne a pale ferruginous. Length 
1 line. 
Extremely like Ocholissa leta (ante, p. 85) from the Amazons. 
Besides the difference in colour (and this is variable inasmuch as 
the elytra are sometimes entirely black), the head is more rounded 
in front, and the prothorax is slightly contracted posteriorly. 
Nematidium posticum. 
N. ferrugineum; fronte leviter convexa; elytris singulis postice bi- 
cristatis. 
Hab. Sarawak. 
Linear, ferruginous; head slightly convex, finely punctured; eyes of 
moderate size, not prominent; prothorax twice as long as broad, the 
sides nearly parallel, the disk with many oblong punctures; scutellum 
triangular; elytra elongate, punctate-striate, the third and seventh
