108 ENTOMOLOGICAL NEWS. [Mar., 16 
Described from 49 females and 15 males, as follows: 
Maryland: Plummer Island (type locality), May 23, 1915 
(W. L. McAtee, L. O. Jackson, J. D. Hood), on flowers of 
wild grape, 10 females, 3 males; Great Falls, May 23, 1915 
(W. L. McAtee, L. O. Jackson, J.D. Hood), on flowers of 
wild grape, Smilax and Rhus toxicodendron, 31 females, 8 
males. 
District of Columbia: Washington, June 6, 1915 ( V. A. 
Lawrence and J. D. Hood), on flowers of wild grape, 7 fe- 
males, 2 males. 
Virginia: Great Falls, May 19, 1915 (L. O. Jackson), on 
flowers of wild grape, 1 female, 2 males. 
The types are now in my collection. 
The specimens here described are very uniform in most of 
the characters used in the differentiation of the species. Other 
individuals, particularly males, taken at the same time and 
possibly in company with them, exhibit variations in the pro- 
portionate lengths of the antennal segments, the sculpture of 
the pronotum, and the abdominal armature ; but more material 
of these forms is needed before their proper status can be 
decided. 
This species is allied by the simple, spinose fringe of the 
lateral, posterior margins of the abdominal tergites, to minor, 
sericatus and analis. The transversely striate pronotum sep- 
arates it readily from minor, which was described from Pana- 
ma; and sericatus, a Porto Rican species, differs radically in 
that the legs of the female are yellow and the body of the 
male orange yellow. Its affinities, then, are with analis, known 
only from Maryland. This is the only species of the genus 
with which it agrees in the male sex in having the ninth ab- 
dominal tergite produced in a pair of converging, fringe-like 
processes. In analis, however, the third antennal segment is 
very long, being about 3.6 times as long as its greatest width; 
the middle portion of the antenna, from segments 3-5, inclu- 
sive, is a very pale grayish yellow; and the mid and hind tibiae 
are annulate at both ends with pale yellow.
