Five males, two females, Seattle. 

 Washington, at Lake Union, the last 

 of August and Hist few days of Sep- 

 tember, 1894. 



Bittitcuinoypha occideninlis^ n. sp. $ . 

 Head wholly black, the front and the pointed 

 face with a white sericeous covering; tlie 

 antennae would extend about to the tip of 

 the first abdominal segment, if bent bacli 

 along the sides. Thorax black, tlie dorsum 

 wholly shining; scutellum yellow; pleura 

 white sericeous, a spot before the root of tlie 

 wing and one above the base of the halters 

 yellowish-pollinose. Abdomen black, tlie 

 posterior margins of the segments narrowly 

 whiti>.h. Femora pale at base gradually 

 darker to the tip, which is black; tibiae 

 ringed with white near the base; second 

 and third tarsal joint--, and tlie Ijase ot" tlie 

 metatarsi, white; the metatarsus is as long 

 as the following joints tiiken together, and 

 its black part is somewhat swollen. Wings 

 hyaline, the second subraarginal cell almost 

 half as long as the first posterior. 



$. The antennae are broken oft 

 from my only specimen ; abdomen 

 less clavate than in B. sackenit\ the 

 appendages dark brown with pale 

 hairs.

 9 , II i mm. 



One male, tsvo females, .Seattle, 

 W.ish. One specimen was collected 

 the last of August, 1894, at Lake Union. 



This is possibly the species referreil 

 to in Osten Sacken's note to B. cla- 

 vipes. Catalogue, p. 36, where he says, 

 ••Specimens from California in Mr. 

 Verrall's collection in London have :i 

 shining thorax ;ind a shorter submargi- 

 nal cell ; thev may belong to a different 

 species." They could not belong to 

 occidentalis unless the word " shorter " 

 in the quotation were a slip of the pen 

 for '• longer." 



Bittacomorpha clavipes Fabr. 



One female Custer, S. D. (Black 

 Hills, 5000 feet), August, 1S92, in a 

 moist meadow. 



Coinparing Osten Sacken's notes in 

 "Western Diptera," p. 207, and in his 

 catalogue, p. 36, it may reasonably be 

 doubted whether the true clavipes has 

 yet been found west of the Rocky 

 Motmtains. 



Pedicia. Latreille, Gen. Crust. 

 Ins. iv, 355, 1809. 



This genus is a somewhat difficult 

 one to determine, from the fact that 

 the palpi have the same structin-e as in 

 the section longipalpi, while the vena- 

 tion and other characters make it out 

 a member of the brevipalpi. In other 

 words, it is a brevipalp Tipulid with 

 long palpi. Several years ago I 

 received from Mr. Chas. Palm a ffne 



Pedicia albivitta Walk. (f. ^■ 



male of P. albivitta Walk., the only 

 eastern species, a particularly handsome 

 insect, which remained an enigma to 

 me for a long time. In Baron Osten 

 Sacken's monograph no figure of the 

 wing is given, and as the venation is 

 very peculiar, I anne.x a figure to 

 facilitate the recognition of the genus. 

 The genus Amalopis Haliday is some- 

 what similar in venation, but has the 

 brown coloring, if at all, in an entirely 

 different pattern.
