The same as the female. Besides the sexual differences pointed 
in the generic description, the following specific details are different 
from those in the female: The body is a shade lighter in color and 
more brassy and the antennae are slightly more pubescent and the 
joints different as follows: the legs are pallid yellowish, and the 
caudal coxae laterally vary to pallid yellow, the other coxae lighter. 
Antennae the same, the hairs sparser and softer, the funicle joints 
longer, distinctly longer than wide, and the scape broader, somewhat 
compressed, the club somewhat more slender, conic-ovate; pedicel 
distinctly shorter than the first funicle joints, funicle joints one to 
three subequal, and joints four to six subequal, the proximal group 
of three broader.

The coloration in this species is fairly constant; it may vary, 
however, to deep metallic French blue; it is more variable in the 
male, the large abdominal area sometimes more extensive, especi¬ 
ally ventrad, and the caudal coxae are sometimes without metallic 
coloration. Specimens which have been in collections for some 
years have a decided bluish color on the head and thorax. The 
metallic coloration on the intermediate and cephalic coxae of the 
female may vary somewhat, too. The shape and size of the joints 
of the antennal funicle may vary considerably, comparatively 
speaking. Thus the last joint may be decidedly more transverse 
than usual, distinctly wider than long, while sometimes all of the 
joints are longer than wide and subequal; at other times, all are 
subquadrate, gradually shortening distad, the first and last joints 
not contrasting. Again, all may be wider than long when the first 
joint is slightly shorter (but larger) than the pedicel. These vari¬ 
ations may all occur in the same series of reared specimens. No 
variation in the number of antennal segments have been met with.
