The tubercles at apex of elytra are very distinctive of this 
species. Тһе eyes are not so widely separated nor concealed 
as in Hypheria assimilis, and I have preferred on that account 
to regard it as an Hthemaia rather than as a Hypheria. Hy- 
phæria and Medicasta are founded on very unsatisfactory 
characters, and I think should be considered as sections of 
Ethemaia. Тһе third tarsal joint in Zthemaia is supposed to 
be bilobed ; this is certainly the case with 2. sellata and E. 
angusticollis, but in a number of others it is feebly bilobed 
above and entire or almost entire beneath. In Hypheria 
assimilis it is feebly bilobed above and entire beneath; the 
ridges over the eyes (as pointed out by Mr. Blackburn) appear 
to be more satisfactory ; X. curtula (which I have from Bev- 
erley) somewhat resembles 4. assimilis in this respect, and 
also as regards the tarsi, and has the eyes forced out, as in 
that species; and if the two genera are to be recognised it 
would belong to Hyphæria. — Medicasta is still more unsatis- 
factory, the species appear to be nothing more than small 
Ethemaic. 
ETHEMAIA EMARGINATA, n. Sp. 
Black; antennæ (funicle darker than scape or club), tibiae, 
tarsi, sides and apex of elytra dull red. Densely clothed 
with muddy-brown scales. A few sete showing at sides of 
prothorax, sides and apex of elytra; legs with whitish setze. 
Head and rostrum slightly convex, the outline (in non- 
abraded specimens) not interrupted by ridges or coste. Ros- 
trum short, broad, dilating to mandibles. Prothorar slightly 
longer than wide (but apparently transverse), sides at apex 
oblique, basal two-thirds parallel; a moderately distinct me- 
dian excavation; densely and strongly punctate, punctures 
entirely concealed by scales. Elytra much wider than pro- 
thorax, shoulders oblique, somewhat thickened, apex emargi- 
nate; seriate-punctate, punctures large, round, subapproxi- 
mate, concealed ; third and fifth interstices distinctly raised, 
near summit of posterior declivity with a small tubercle, on 
summit itself distinctly tuberculate. ^ Abdominal punctures 
traceable. Tibie tipped with black sete; third tarsal joint 
feebly bilobed above, still more feebly beneath. Length, 5; 
rostrum, 3; width, 2 mm. 
Hab.—Forest Reefs. 
The clothing of this species is so dense that all traces of 
punctures are lost on the prothorax and elytra. It is allied 
to the preceding species, but the apices of the elytra are very 
different.
