Didactylomyia longimana Felt. 



A single example of this striking male was first taken at Auburn- 

 dale, Mass., August 16, 1906, by Mr. C. W. Johnson. Several speci- 

 mens of both sexes were collected by Mr. C. P. Alexander in August, 

 1909, at Woodworth's Lake in the Adirondacks, altitude about 1,500 

 feet. The female had not been recognized before.

 segment, sparsely haired, yellowish basally, the distal two-thirds fuscous ; fif- 

 teen subsessile segments, the fifth with a length fully three and one-half times 

 its diameter, the distal segment produced, the basal enlargement with a length 

 thrice its diameter and apically a moderately stout, fingerlike process. Palpi ; 

 the first segment subquadrate, the second with a length three and one-half 

 times its diameter, the third shorter than the second, slender, the fourth one- 

 half longer than the third and somewhat dilated. Thorax mostly yellowish

 C. 1481. 



Asynapta apicalis new species. 



The male of this species was taken August 24, 1909, by Mr. C. P. 

 Alexander in a quarry at Woodworth's Lake in the Adirondacks at an 

 elevation of 1,540 feet. It is related to A. fiircafa Felt from which it 

 is readily separated by the longer stems of the flagellate antennal 

 segments and the peculiar genitalia. 



Male. — Length 2.75 mm. Antennae one-half longer than the body, thickly 

 haired, light brown ; sixteen segments, the fifth with a stem two and one-half 

 times the length of the basal enlargement, which latter has a length one-half 

 greater than its diameter. Palpi ; first segment slender, with a length thrice 

 its diameter, the second as long as the first, stouter, the third one-half longer 

 than the second, more slender and the fourth one-half longer than the third, 

 slightly capitate. Mesonotum yellowish brown. Scutellum and postscutellum 

 fuscous yellowish. Abdomen mostly yellowish brown. Halteres and coxae 

 yellowish transparent. Legs a nearly uniform light straw, except the two
