Pyrgota Chagjioni, n. sp. 



(^ .— Head reddish, vertex reticulated with brown, cheeks and occiput 

 yellowish, antennal fovea3 brown; antenna yellow, thorax and scutellum red; 

 numerous fine brown specks are so arranged as to form two obsolete dorsal 

 lines and two spots on each side divided by the suture ; this character is 

 especially noticeable when looking from the head toward the scutellum, 

 and gives the disc of the thorax a rugose appearance. Abdomen narrow, 

 brownish, shining, posterior margins of the second, third, fourth and sides of 

 the fifth segment more or less blackish. Halteres yellow. Legs variable in 

 colour, with thick black hairs, especially on tibite, anterior and middle 

 coxce, basal half of all the femora and tibiae, and all except the terminal 

 joint of the tarsi yellow ; posterior coxae and the terminal portion of the 

 femora reddish; outer half of all the tibiae and the terminal joint of the 

 tarsi blackish ; the outer portion of the posterior tibiae is intensely 

 black, while the black of the anterior tibi^ is due largely to long 

 thick hairs. The wings can best be described by reversing that of 

 P. valida, Harris, given by Loew (Monog., Pt. HI., p. 75). The 

 whole surface of the wing has a rather uniform yellowish-gray tinge, 

 variegated by numerous irregular, more or less confluent, maculations of a 

 dark brown colour ; at the apical portion of the wing the markings 

 become more united, forming a noticeably darker area ; the dark 

 markings are also more prominent at the junction of the second and 

 third longitudinal veins and along the small cross veins ; in the costal 

 and marginal cells the markings are larger and subquadrate ; the costal, 

 auxiliary and basal half of the first and second longitudinal veins, yellow, 

 the others dark brown. Length 14 mill. 



One specimen of this handsome species was collected by Mr. Gustave 

 Chagnon, on Montreal Island, Canada.
