io8 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, Smila.v 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, I 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 an alls. 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.
