interstices more or less truncate apically, and longer than the 
others, the third being broadened before the apex and also 
slightly at the base and punctured ; the second and fourth 
are narrowed and not continued to the apex, the fifth longer 
than the remainder and transversely truncate; the sixth and 
seventh are of equal length, but the latter is the broadest ; 
the eighth is longer and narrower than the ninth, both being 
transversely truncate. Abdomen (fig. ¢): the cavity in the 
second abdominal segment has the sides almost parallel or 
slightly incurved as far as the inner posterior angles, and 
is then rounded and fringed with hair, becoming, however, 
slightly sinuous laterally, and ending in a minute spine; the 
metasternal femoral depression is marginally denticulate. 
Length 3°9 mm.; breadth 1 mm. 
The female is very similar to that of the preceding species, 
but differs chiefly in the much smaller size, the flatness of 
the front, and the absence of the depression over the eyes, 
and is much paler in colour.

closely punctured, the interstices very minutely punctured, 
becoming rugose and hairy towards the apex; the first inter- 
stices smooth, shiny, and strongly carinate, slightly divergent 
towards the apex, but becoming parallel before the termina-
