it is probable that the male has the eighth joint of the antennæ 
considerably enlarged as is usually the case in this genus, there 
is just a slight enlargement visible in the specimens before me ; 
the species may be known by the reddish-fulvish head and 
thorax and the paler elytra. 
Cerophysa nigricollis n. sp. 
Black, the femora piceous, the abdomen flavous, thorax 
opaque, finely granulate, obsoletely sulcate, elytra metallic blue, 
closely punctured, the interstices slightly rugose. 
Mas. The sixth and seventh joints of the antennæ dilated. 
Length 2 lines. 
G. Head black, impunctate, shining, the frontal tubercles rather 
obsolete, transverse, clypeus with an acute central ridge, eyes 
large, antennæ scarcely extending to the middle of the elytra, 
black, the basal joint rather short, claviform, the second very 
short, the third elongate, the fourth shorter than the third, the 
fifth longer than the preceding joint and slightly dilated, the sixth 
longer than the seventh, both strongly widened (terminal joints 
wanting); thorax subquadrate, but little wider than long, the 
sides deflexed, the base slightly narrowed, the lateral margins 
néarly straight, the surface obsoletely depressed, black or nearly 
so, of a silky, opaque appearance, very minutely granulate 
and punctured, when seen under a strong lens, scutellum broad, 
black, elytra metallic blue, distinctly punctured in close and very 
irregular rows, the interstices slightly rugose, legs black, or 
piceous, the posterior femora and the abdomen flavous, the tibiæ 
unarmed, the first joint of the posterior tarsi longer than the 
following joints together. 
Hab. Toungoo, Burmah. 
In the female the antennæ have the sixth and seventh joints 
likewise dilated but to a much smaller degree and the legs and 
the abdomen are more or less black, but this latter colour may 
also occur probably in the male sex, in this the anterior tarsi have 
the first joint distinctly widened; the thorax in the present species 
has à peculiar silken appearance, caused by the fine granulate 
surface. 
Astena(?) nigromaculata n. sp. 
Fulvous, the antennæ (the basal joints excepted) and the 
abdomen black, head and thorax impunctate, elytra extremely 
finely and closely punctured, each with a broad longitudinal black 
band of variable width. 
Var. The elytral band divided into two large spots. 
Length 2-2 1/2 lines.
