segments, the fifth cylindric with a length about 2 r / 2 times its diameter, a sparse 

 subbasal whorl of stout setae and a scattering subapical band of long, more 

 slender setae. Slender horseshoe-shaped circumfili extend from the basal third 

 of the segment to a little beyond the tip. Palpi: short, slender, the first seg- 

 ment oval, the second with a length four times its diameter, fusiform, slender. 

 Mesonotum dark reddish brown. Scutellum and postscutellum reddish brown. 

 Abdomen mostly fuscous yellowish. Wings unusually narrow, with a length 

 about three times the width, a well marked crossvein as in Winnertzia, the third 

 vein uniting with the margin just beyond the apex of the wing, the fifth vein 

 wanting, the sixth well developed and joining the posterior margin at the 

 basal half. Halteres and legs mostly fuscous yellowish. Claws moderately 

 long, stout, slightly curved, the pulvilli rudimentary. Ovipositor nearly as long 

 as the abdomen, the terminal lobes slender, sparsely setose, triarticulate, the 

 basal segment broadly quadrate, the second segment narrow, the third with a 

 length over twice its diameter and tapering to a narrowly rounded apex. Type 

 Cecid. 1704. 



Didactylomyia robusta new species. 



This midge was taken September 14, 1917, by Mr. Howard Not- 

 man, at Keene Valley, N. Y. It is easily distinguished from other 

 males referable to this genus by the somewhat moderate length of 

 the terminal clasp segment. 



Male. — Length 1 mm. Antenna? twice the length of the body, rather 

 thickly haired, dark brown, 15 segments, the fifth with a stem % longer than 

 the cylindrical basal enlargement, which latter has a length 2Y2 times its diam- 

 eter, terminal segment somewhat produced, with a length over three times its 

 diameter and apically a slender, somewhat capitate process. Palpi, the first 

 segment with a length nearly twice its width, the second l /> longer, swollen 

 distally, the third as long as the second, more slender and the fourth y 2 longer 

 than the third. Mesonotum dark reddish brown. Scutellum and postscutellum 

 reddish yellow. Abdomen yellowish brown. Genitalia fuscous. Halteres yel- 

 lowish transparent. Legs mostly dark brown. Claws moderately stout, 

 strongly curved, unidentate, the pulvilli about half the length of the claws. 

 Genitalia : basal clasp segment moderately stout, short ; terminal clasp segment 

 y 2 longer than the basal clasp segment, rather stout, tapering and curving 

 gently ; dorsal plate long, broad, deeply and triangularly emarginate ; ventral 

 plate moderately long, rather deeply and roundly emarginate, the lobes finger- 

 like. Harpes moderately produced, chitinized and roundly truncate distally. 

 Type Cecid. 1727. 



Porricondyla johnsoni new species. 



The one male was taken August 23 by Professor C. W. Johnson, 

 at Brookline, Mass. It is closely related to P. pini Felt and P. biden-
