THE CANADIAN ENTOMOLOGIST. 139 



localities already given I have evidence of its occurrence at Turtle 

 Mountain, Pelly, Edmonton, Regina, Prince Albert, and Calgary. 



This gall is not found in the vicinity of Toronto nor in the adjacent 

 counties ; but I am informed by Mr. Jas. Fletcher, Dominion Entomologist, 

 that it is more or less common in the Ottawa region. 



In May '84, 1 liberated ten pairs of E. solidaginis, in an untilled field, 

 densly grown up with Solidagos, north of the city, but found no galls 

 afterwards. In June '88 I liberated six pairs in a field east of the city, 

 but no galls have been found. 



Dr. Fitch gives the habitat " New York," and Osten-Saken, " Wash- 

 ington " (D. C.) There can be little doubt of the parasitic habit of the 

 M. nigricans larvse. None of the galls gave both beetle and fly ; the 

 cells in the galls which gave beetles were similar to those which gave 

 flies, and in all the galls examined — out of which came beetles — there 

 were found fragments of Enrosta larvae or pupae. 



The M. nigricans larvae are most probably external feeders. 



It is very desirable that some observer should take up this investigation, 

 and from a careful examination of the immature galls determine the relation 

 between the beetle and the fly. 



A NEW DASYLOPHIA FROM FLORIDA. 



BY ANNIE TRUMBULL SLOSSON, NEW YORK CITY. 



Dasylophia puntagorda, n. sp. 



$ . — Head and thorax appearing palest gray from admixture of pure 

 white with cinereous. Abdomen, secondaries and ground colour of 

 primaries sordid white. Primaries streaked longitudinally with blackish, 

 which contrasts violently with ground colour. A diffuse, heavy, blackish 

 shade runs obliquely from apex inward. A curved blackish line, reaching 

 neither costa nor internal margin at outer three-fourths of wing. Sub- 

 marginal row of distinct, blackish spots, two of which are much larger 

 than the rest and margined with white. Costa interrupted near apex by 

 white spots. Fringe sordid white, interrupted by blackish. Somewhat 

 smaller than D. anguina, S. & A., and differing markedly from that 

 species in its sharp contrasts of colour, which make it appear like a purely 

 black and white insect. It has no ochreous shade. The antennce 

 resemble those of D. ajiguijta, the pectinations not as long as in those of 

 D. interna, Packard. Described from two males taken at light. Punta 

 Gorda, Florida.
