seems plausible that at this time the silky coating is being applied. 

 An investigation of the character of the different secretions would 

 easily decide this question. 



NOTES ON NORTH AMERICAN CHLOROPID^ (DIPTERA). 



,T. R. MALLOCH, 

 Illinois State Laboratory of Natural History. 



In a paper which presented a generic synopsis of the family 

 Chloropidre 1 I described an insect which at the time I considered 

 as a possible variety of Chloropisca glabra Meigen, giving it the 

 varietal name clypeata. Since writing that paper I have obtained 

 a number of specimens of clypeata from different localities, and an 

 examination of these has convinced me that they belong to a spe- 

 cies that is distinct from glabra; clypeata should therefore be used 

 in a specific instead of a varietal sense. 



The species is distinguished from glabra by its larger size, aver- 

 aging 3 mm., and by the differently shaped frontal triangle, which 

 is comparatively longer and narrower than in glabra, with its sides 

 converging appreciably less from front ocellus to anterior margin. 

 The fore tarsi usually have the whole of the first joint and the 

 basal portion of the second yellow, whereas in glabra both joints 

 are blackened except, rarely, the base of the first joint, the clypeus 

 also is generally yellow, very rarely slightly brownish. 



In addition to the Illinois localities given in connection with the 

 original description Algonquin and Urbana I have taken speci- 

 imens at Centerville, August 16, and at Monticello, June 21 ; and 

 I have seen specimens from Plummer's Island, Md., July 4 and 

 19, and from Anacostia, D. C., July 22, taken by W. L. McAtee 

 and W. D. Appel. 



The following new species were taken by Mr. C. A. Hart and the 

 writer in 1914. 



Chloropisca parviceps, n. sp. 



Female. Glossy yellow. Head yellow; occiput black, slightly shin- 

 ing; frontal triangle glossy black; basal joints of antennae brownish black, 

 upper margin of third broadly brown; arista fuscous, yellowish at base; 

 face paler than frons; mouth parts entirely yellow. Disc of mesonotum 

 glossy black, shading off into the yellow lateral margins; humeri with a 

 large, poorly defined black spot; mesopleural spot black; sternopleural 

 one yellowish red; scutellum with sides black at base, the remainder glossy 

 yellow. Dorsum of abdomen glossy blackish brown, the posterior margins
