474 Mr. F. P. Pascoe on some new or little-known 
from the oral organs as distinctive of nearly allied genera, principally 
because they are difficult to ascertain, and are probably assumed in 
the majority of cases, except in the type of the genus: but in this 
instance the toothed inner maxillary lobe is an exception to the 
characters of this subfamily as laid down by M. Lacordaire. The 
mentum is also very peculiar, it is very much produced in front ina 
nearly semicircular form, with short sides each of which gives off a 
sort of triangular process at right angles to the main axis, in this 
way forming a kind of enclosure round the base of the lower lip. 
The clypeus let into the front and distinct from the antennary orbits, 
is also very different from the same organ in Hucyrtus, where it runs 
into and seems a part of the orbits. 
Gauromaia dives. 
G. purpureo-metallica, nitida; corpore infra, antennis pedibusque nigris. 
Hab, Malacca (Mount Ophir). 
Metallic purple, smooth and shining; head and prothorax finely 
punctured, the latter transverse, rounded and finely margined at the 
sides and base, the latter and apex of nearly equal breadth; scu- 
tellum triangular; elytra ovate, broader than the prothorax, striato- 
punctate, punctures small and approximate, spaces between the strize 
broad and minutely punctulate; body beneath and legs black; femora not 
thickened, the anterior slightly curved, a faint shade of coral-red in the 
middle; tibiee nearly equal in length, more or less curved; tarsi sub- 
equal; antenne black, with the last four joints pubescent. Length 7 
lines. 
Puaerpis [Cnodaline]. 
Characteres ut in Eucyrto ; sed clypeus productus ; mentwm minus transver- 
sum,in mediocarinatum, Antenne breviores, articulis magis transver- 
sis. Prothorax apice paulo productus. Femora incrassata, in medio 
subtus dentata. 
The last character also distinguishes this genus from the foregoing, 
from which, moreover, it differs in the larger comparative size of the 
claw-joint, and the shortness of the anterior tibie. 
Phaedis elysius. 
P. ceruleus, nitidus ; elytris aureo-zeneis, lineato-punctatis. 
Hab, Sarawak. 
Sky-blue, very smooth and glossy; head rather remotely punctured, 
the lateral line, separating the clypeus from the front, extending above 
the base of the former; antenne reddish ferruginous, pubescent, scarcely 
longer than the breadth of the head ; palpi pale ferruginous ; prothorax 
with numerous small, rather remote punctures, finely bordered on all
