 heavily chitinized and recurved genitalic hooks.

 thickly long haired, brownish and presumably with 16 segments Conly 8 were 

 attached to the specimen), the fifth with a stem twice the length of the cylin- 

 drical basal enlargement, which latter has a length about twice its diameter. 

 Palpi: the first segment with a length about three times its diameter; the sec- 

 ond apparently as long, the third about twice the length of the second, more 

 slender and the fourth about Y\ longer than the third. Mesonotum dark red- 

 dish brown. Scutellum pale yellowish. Postscutellum pale orange. 

 reddish brown. Genitalia yellowish. Venter dark brown. Halteres pale yel- 

 lowish. Legs a pale yellowish brown. Claws missing. Genitalia: basal 

 clasp segment short, broad, the internal basal angle with a heavy, strongly 

 recurved bidentate chitinized hook, the extreme distal margin thickly clothed 

 with stout setae; terminal clasp segment moderately long, strongly curved, 

 falcate, the distal portion expanded, obliquely truncate and with the tip pro- 

 duced as a narrowly triangular fleshy lobe ; dorsal and ventral plates indistinct 

 in the preparation. Harpes forming a heavy, strongly recurved hook apically. 

 Type Cecid. 1343. 



Porricondyla bidentata new species. 



The striking midge described below was taken August 26, 1917, 

 by Mr. Howard Notman at Keene Valley, N. Y. It approaches P. 

 pini Felt, from which it is most easily distinguished by the more 

 strongly chitinized hooks of the genitalia and especially by the biden- 

 tate hook distally and internally on the basal clasp segment. 



Male. — Length 2 mm. Antennae % longer than the body, thickly haired, 

 dark brown, the basal segments yellowish, 15 segments, the fifth with a stem 

 2 T / 2 times the length of the cylindrical basal enlargement, which latter has a 

 length i T /i times its diameter, terminal segment produced, with a length four 

 times its diameter, the apex a short cone. Palpi : first segment with a length 

 about three times its diameter, the second a little longer, broader, the third 

 with a length about twice the second and the fourth % longer and more slender 

 than the third. Mesonotum dark yellowish brown, the median area lighter. 

 Scutellum and postscutellum pale yellowish. Abdomen rather thickly haired, 

 dark brown, the enlarged genitalia yellowish. Halteres and legs mostly dark 

 straw, the distal tarsal segments of the middle pair whitish. Claws moderately 

 long, stout, unidentate, the pulvilli as long as the claws. Genitalia : basal 

 clasp segment short, broad, the internal basal angle prolonged in a rather 

 stout, recurved, bidentate hook ; terminal clasp segment moderately long, 

 strongly curved, falcate, the distal portion expanded, obliquely truncate and 

 with a chitinized spur at the apex ; dorsal plate short, broad, the lobes appar-
