THE CANADIAN ENTOMOLOGIST. 27 



second, third elongate-conical at its base. Epistoma greatly produced, 

 sparsely covered with yellow tomentum. Proboscis not surpassing the 

 oral margin. Occiput beset with yellow tomentum. Thorax with yellow 

 tomentum, and copious long pile of lighter colour on the anterior margin, 

 along the sides and on the pleurae. There is a distinct patch of white 

 pile, beginning above the root of the wing, passing around in front, and 

 ending on the pleura below the root of the wing. In some specimens the 

 patch is present on the pleura only. Bristles at the posterior angles of the 

 thorax yellow, those along the posterior margin of the scutellum black. 

 The tomentum of the scutellum is yellow. Abdomen with a mixture of 

 black and yellow tomentum, the latter colour prevailing, the black mostly 

 on the middle of the second, third and fourth segments. Light yellow 

 pile on the sides of the abdomen, except at the posterior angles of the 

 second, third, fourth and fifth segments, where it is black. Venter black, 

 with yellow tomentum. Front tibia3 bristly. Legs yellow tomentose. 

 Reddish colour of the legs changing to black on coxae and tarsi. Claws 

 of front tarsi distinct. Basal portion of wings brown, the apical portion 

 entirely hyaline. The outline of the brown colour extends in a more or 

 less broken line from the apex of the auxiliary vein to a point on the hind 

 margin of the wing, situated a little inside of the apex of the axillary cell. 

 Apex of the anal cell hyaline in all of the specimens, that of the axillary 

 cell distinctly hyaline in some of the specimens only. A round hyaline 

 spot at the anterio-exterior angle of the second basal cell. 



In the distribution of the brown colour on the wing, as in several 

 other characters, this species comes c\osq\.o A. perplexa, Coc]., a Californian 

 species. It differs from that, however, in having a shorter proboscis, 

 yellow tomentum on the occiput, black bristles on the scutellum, and in 

 some other points of minor importance. In the description of A. perplexa 

 no mention is made of a hyaline spot in the second basal cell, a character 

 which is present in each of the specimens of A. JVemakagonensis. This 

 species is not rare in the St. Croix region. .Sixteen specimens, all of them 

 in the collection of the Milwaukee Publ. Mus., were taken last summer by 

 the collecting expedition of that institution as follows : Four, July 25, 

 near the mouth of the Nemakagon River, Burnett Co.; ten, July 28-30, 

 near the mouth of the Yellow River, Burnett Co.; one, Aug. 4, near the 

 Kettle River Rapids, Burnett Co., and one, Aug. 6, at Randall, Burnett Co.
