Genus protenthes 



Johannsen, Ent. News, 1907 ; = Tanypus Johannsen, Bui. 86 

 The type of this genus is c i n c t u s (= p u n c t i p e n n i s 

 Meigen). To this genus belong all species which I described under 

 Tanypus in Bui. 86, with the exception of T. posticalis Lund- 

 beck. The following new species will find a place in the key given 

 in Bui. 86 with s t e 11 a t u s , from which it differs in its wing 

 markings and leg coloration. 



Protenthes pulcher n. sp. 



Female. Head, including proboscis, and basal joint of the 

 antennae cream-white, the fiagellum pale fuscous, thirteenth and 

 fourteenth antennal joints somewhat enlarged, fifteenth joint dark 

 brown at tip ; labrum and palpi fuscous ; occiput white with a brown 

 spot back of each eye; eyes black, deeply emarginate. Thorax 

 cream-white, the median stripe brown, blackish anteriorly, divided, 

 posterior border emarginate, lateral stripes deep brown, produced 

 backwards to the scutellum, scutellum white, scutellar suture nar- 

 rowly brown ; metanotum and sternum brown ; pleura with brown 

 spots as follows : a pear-shaped spot on each side of sternum sepa- 

 rated from the brown of the sternum by a narrow white line, a tri- 

 angular spot cephalad of this, and three small ones near base of 

 wing. Abdomen wanting. Legs white, the tips of all femora, tibiae 

 and metatarsi widely dark brown, second joint of all tarsi wholly 

 white, third, fourth and fifth joints wholly brown, fourth joint 

 linear. Wings thickly hairy, with a brown spot covering the cross 

 veins, a broad fascia extending from apex of R-^ to the posterior 

 margin of the wing, the band widening wherever it is crossed by a 

 vein and constricted again behind it, a subtriangular spot near the 

 posterior margin behind the cross veins, and a small one on the 

 anal lobe. Venation like that of P. culiciformis but the 

 media slightly more curved down at the extremity [Bui. 86, pi. 27, 

 fig. 15]. Halteres pale. Length about 2^ to 3 mm. Old Forge, 

 N. Y. 



Genus trichotanypus 

 Kieffer, 1906 



T. posticalis Lundbeck is the only representative of the 

 genus. The absence of the vein R2+3 and the retracted position of 

 the M-Cu cross vein are the distinctive generic characters. I have 

 a specimen of this species from Ithaca, N. Y.
