46 Mr. G. Lewis on Histeride from Venezuela. 
those who study the family will be able to form an idea of its 
peculiarities and to judge whether or not I have assigned it 
rightly to Phelister. ‘lhe specimen is unfortunately unique 
and the sex of it is not apparent without dissection; but I 
cannot for a moment think the structure of the prosternum 
can differ in the male and female.

The minute surface sculpture of this species gives it the 
appearance of opacity. ‘The frontal stria is lightly impressed 
and formed like that figured for 
Homalodes faustus and others in 
Marseul’s monograph. The 
singular structure of the pro- 
sternum may be seen by the 
figures given here. The region “© ™~ PL C ae 
of the strie is built up to the TS j 
same plane as ‘the mesosternum —
