1907 Excerpt: ...with a number of short dark hairs; posterior
tibise light brown sericeous behind; fore metatarsus with nine
(sometimes ten) long, slender comb teeth; bases of the claws
lighter than the rest of the tarsus; the claws themselves very
minute. Variation.--In examples with fuliginous wings the abdomen,
except the first two and last plates above and beneath, is
generally black. The black may also encroach on the posterior part
of the second segment and on the sides of the last one.
Male.--Anterior margin of the clypeus extending obliquely downward
and inward from the side, then transverse, slightly cmarginate, a
little reflexcd; a faint trace of silvery pubescence sometimes
present on the cheek just behind the eye, and another on the
posterior end of the median segment or in some cases above the hind
coxa; body rather more densely clothed than in the female; sixth
and seventh ventral abdominal plates slightly emarginate behind;
terminal ventral plate with its hinder border rounded at the sides,
acuminate in the middle; terminal dorsal plate evenly rounded; the
abdomen generally with an opalescent luster; generally black, but
sometimes more or less ferruginous on the first, second, or both
segments; legs usually entirely black. In other respects the male
resembles the female. Length.--Females, 17-2-2 mm.; males, 13-19
mm. This species appears to be found only in our Southern and
Western States and in Mexico. 1 have studied examples from Tifton
and other (unnamed) places in Georgia, Texas, New Mexico
(Alamogordo, taken from April 26 to June, 1902, and elsewhere);
southern Arizona (F. II. Snow, August, 1902); Los Angeles County,
