Dec, 1918] Nearctic Species of the Geiius Laphria 163 



Laphria felis var. varipes new variety. 



Colorado, (U. S. N. M.) ; Beulah, N. Mex., July 22, Cockerell. 

 A male, the type, (U. S. N. M.). 



Laphria felis var. felis Osten Sacken. 



Kaslo, B. C, June 8, R. P. Currie, (U. S. N. M.); Yellow- 

 stone Park, July 25, 1907, W. Robinson, (Hine) ; Currant 

 Creek, 8,000 feet, Uinta National Forest, Utah, Aug. 13, 1917, 

 J. Silver, (Biol. Survey). 



Laphria felis var. crocea new variety. 



Type a male from Pullman, Washington, July 6, H. E. 

 Burke, (U. S. N. M.). 



Other specimens examined: Mt. Hood, Ore., H. K. Morri- 

 son, (U. S. N. M.); Hope Mts., B. C, July 18 and 27, 1900, 

 R. V. Harvey, (Hine). 



I am tempted to call this form a distinct species, and would, 

 except for the fact that two males from Mt. Hood, Ore., one 

 var. xafithippe and one var. crocea are so nearly alike in almost 

 all respects except the color of mystax and beard, that it makes 

 me doubt whether the slight differences in genitalia (Fig. 15) are 

 significant. 



Laphria scorpio new species. 



Mystax black, decumbent pile of face golden in male, whitish to 

 greenish yellow in female. Beard and coxal hair grayish to silvery. 

 Face, coxse, oblique anterior fascia of thorax and pleurse, more or less 

 gray to white poUinose. Rather sparse pile of thoracic disk and 

 scutelliim mostly golden; more decumbent and conspicuous behind. 

 Thoracic bristles black except tuft in front of halteres which is yellowish. 

 Pile of abdomen golden, being more recumbent on posterior parts of 

 segments and of abdomen as a whole, it there appears more dense. 

 Hair of legs gray and black; wings pale ftimose. Hypopygium black; 

 forceps stout, curved; inner apical process, twisted longitudinally so that 

 its median part lies in a vertical plane, surpassing forceps a little and 

 deflexed apically so that it almost touches apex of forceps. A pair of 

 the hooks from interior of h^^popygium often are in such a position as to 

 obscure the relative positions of process and apex of forceps. There is 

 also some variation in the shape and deflexion of process (illustrated 

 in Figiu-e 16), but for the present these are not given taxonomic recogni- 

 tion. Length, 14-17 mm. 



The females, difficult to distinguish from those of the fol- 

 lowing two species, may best be recognized by the hair of thorax
