impression less deep. /ytra red, of the same form as in F. 
cavifrons. Abdomen with the first segment very short, and 
narrower than the elytra; the second is twice as long as the 
first and equal to the third or fourth segment, gradually 
increasing in width from base to apex, the rest of the seg- 
ments rapidly decreasing in width and seemingly so in length, 
as they are retracted in dead specimens.

spine; fourth dorsal segment as long as the others taken 
together, not margined; posterior coxe approximate. Length 
3-4 mm. 
lead as wide as long, vertex quadrate, carinate at the sides, 
the carine nearly obsolete posteriorly, with two shallow fovez 
less than one-fourth from the base, and mutually three times 
farther distant than either from the basal carine; circumam- 
bient sulcus shallow near the fovea, deeper and wider near 
the frontal margin. Supra-antennal tubercles retusely angu- 
late outside and separated by a notch from the arcuate frontal 
margin; clypeus evenly rounded, punctured; sides of the head 
continuously convex with the posterior part of the vertex and 
the gular region, and with a strong, pointed, conical spine 
(perhaps bearing an ocellus) in the position usually occupied 
by the eyes; occiput carinate in the middle; gula unicarinate; 
neck faintly carinate; mentum and labrum very short, emargi- 
nate; antennal cavities shallow. Px/pz with the second joint
