78 ENTOMOLOGICAL NEWS. [March, 'O2 



altogether black abdominal pile. The description speaks of 

 white hairs about the head which do not exist in L. thoracica, 

 but does not shake my belief in the synonymy." 



For some time I have had in my collection two specimens, 

 one ( S ) collected at Jackson, Alabama, Oct. 23, '94 ; the other, 

 ( 9 ) from Dr. G. de N. Hough, was collected by Mr. G. R. 

 Pilate at Tifton, Georgia, Oct. 10, '98. Last year (Oct. 21, '01) 

 Mr. E. Daecke obtained a male of the same species at Manu- 

 muskiu, N. J., and on Oct. 2oth I was fortunate enough to 

 capture a female at Riverton, N. J. The above measure re- 

 spectively 20, 14, 20 and 19 mm. Macquart's description was 

 based on a male, and the two specimens before me agree with 

 it in all of the more important features : palpi black with black 

 pile, beard white, pile on the sides of the face white, mystax 

 black with some intermingling white hairs, pile on the front 

 black and on the sides of the head white ; abdomen narrow, 

 with black pile ; femora and tibia with yellow hair which, on the 

 under side of the posterior legs, is black, In the females there 

 seems to be considerable variation, the pile on the face (includ- 

 ing the mystax), the beard and inferior orbits is entirely 

 black, while the specimen from Riverton has only a small 

 upper portion of the orbits slightly white pilose. 



In general appearance it more closel}' resembles D. flavicollis 

 than D. thoracica. From the former it is readily separated by 

 its black mystax, the pile on the thorax is noticeably thinner 

 and entirely erect, the shining, glaucous ground color showing 

 clearly. From thoracica it differs in being much narrower, the 

 head proportionately larger and nearly as wide as the thorax ; 

 the hair on the front and vertex black, and the pile on the 

 thorax shorter, more sparse and of a dull, not a bright yellow. 



This seems to be an autumnal species. Of the other four 

 species found in this section I have no records of capture later 

 than the middle of July. 



A HERMAPHRODITE LYC^NA. On July i4tli, 1901, I was fortunate 

 enough to capture, at Fortune's Rock, near Biddeford, Me., a specimen 

 of Lye fen a pseudargiolus, summer form neg/ecfa, whose wings on n^ht 

 side are typical male, while those on the left are heavily bordered with 

 black, equally typical of the female sex. A. F. WINN, Westmount, Que.
