Laphria franciscana Bigot. 



Laphria franciscana Bigot, J. M. F. Dipteres nouveaux ou peu connus. 10 (1). 

 Annales de la Societe Entomologique de France, 5th ser., 8, 1878. p. 225. 

 (California.) 



There is little in general appearance to distinguish this 

 species from L. sicula. In both of these species the females 

 have less pale hair among bristles of mystax (sometimes none), 

 and less white hair on sides of abdominal segments. In both 

 sexes, L. franciscana has notably less of the latter pile than has 

 sicula. I am unable to perceive any differential coloring of 

 thoracic pile, all of it appearing pale when held in the proper 

 light. 



Both species have a shining, opalescent, bluish, black surface which 

 is characteristic. Color of hypopygium and its hairs as in L. sicula; 

 forceps from above stout, curved, constricted beyond middle, then 

 expanded into a hollowed out spoon shaped apex ; from side only slightly 

 emarginate apically, claspers not so stout and without large basal 

 insertion as in sicula (Fig. 20). Length 12-16 mm. 



Specimens examined: Grouse Mt., B. C, June 29, 1905, 

 (Hine); Western Washington Territory, H. K. Morrison, 

 (U. S. N. M.); Siskiyou Co., Calif., (U. S. N. M.); Santa Cruz 

 Mts., Calif., (U. S. N. M.). 



A general and somewhat damaged specimen from Cayuga 

 Lake, N. Y., (M. C. Z.), has genitalia more Vike franciscana than 

 sicula, but agrees better with the latter in the amount of white 

 pile on abdomen. On account of its condition it is not more 

 definitely placed. 



It should not be overlooked that the present identification 

 of L. franciscana is perfunctory. Without examination of the 

 type no identification of a species of Laphria is beyond question.
