Paciiic, becomes less remarkable upon learning that Telmatoge- 

 ton alasl-ensis Coq. is recorded from Alaska, Oregon and Cali- 

 fornia. Strangely enough the only other recorded representa- 

 tives of this allied genus (T. sanctipauli Schin.) occurs on the 

 island of St. Paul (T^ew Amsterdam) in the South Indian 

 ocean. 



Charadromyia nov. gen. 

 Type C. torrenticola. 



This genus is evidently allied to Telmato(/eton, differing in the fol- 

 lowing characters: Front not deeply excavated; palpi normally two- 

 jointed, the basal large and bulbous, the apical smaller and more 

 elongate. Apex of each tarsal joint bears a pair of minute ventro- 

 lateral spines; claws not furcate at extreme tip, either simple in 

 both sexes or bearing a peculiar spatulate comb in the male; 4th 

 tarsal joint equal to 3rd. Wings only slightly longer than abdomen; 

 auxiliary vein starting from wing base, but not reaching the costa; 

 3rd and 4th longitudinal veins connected by oblique cross-veins; 

 furcation of 5th longitudinal vein before the middle of wing; 6th 

 well defined, 7th obsolescent.

^ Head, thorax and abdomen velvety black, the body moderately 

 pruinose especially the pronotum; legs, scutellum, postscutellum and 

 wings rusty-black, humeral angles often dull testaceous. The small 

 cubital head deeply inserted and hidden by the projecting mesonotum.

 width of head, (identical in both sexes), 7-jointed and a basal ring- 

 joint, 1st very large and thickened, length about one and the breadth,
