HELOTA ACUTIPENNIS. 167 
but the crenulations of the lateral edges are more irregular ; 
the scutellum agrees with that of Lesnei. 
The elytra are subparallel and end each in a narrow 
pointed prolongation ; these prolongations are dehiscent and 
provided with a raised keel; the lateral margins of the 
elytra are minutely notched at the basal and apical third. 
The sculpturing of the elytra agrees pretty well with that 
of Lesnei, but the glossy warts are less numerous and 
those on the middle portion larger. 
The undersurface of the head (with the exception of 
the throat) is rather sparingly covered with very distinct 
punctures; on the lateral portions of the prosternum the 
punctures are larger and on the sides of the middle por- 
tion smaller; the middle of the meso- and metasternum 
is almost impunctate, the brassy lateral portions are distinct- 
ly punctured. On the ventral segments a very minute, 
though distinct, punctuation is present. The last ventral 
segment is strongly transverse, and deeply notched in the 
middle at the hind margin; at both sides of the notch 
the hindmargin is concave, which makes the angles at the 
open side of the notch subacute and slightly prominent ; 
at both sides of the top of the notch a shallow rounded 
impression is to be seen '). 
The metallic coloured apical portion of the femora is 
densely punctured, the tibiae are* very finely and rather 
remotely punctured, and distinctly constricted at the upper- 
side just before the apex. 
Hab. Yunnam-Sen. — The above described specimen 
has been communicated to me by Mr. A. Grouvelle and 
belongs to the Natural History Museum at Paris. 
Helota epipleuralis, n. sp. &{. 
A small species (7 mm. long) which, with the aid of 
1) In Zesnei © the apical margin of the last ventral segment is regularly 
rounded, not concave at both sides of the notch; the notch itself is horse- 
shoe-shaped, and the open side is narrowed by two slightly oblique small 
callosities.
