being almost uniform in color and not forming a distinct median 

 narrow golden triangle. 



Type male and allotype female, White Mts., Morrison, 

 (U. S. N. M.). Several paratypes with same date and one 

 female from Camel's Hump, Vt., P. S. Sprague, (U. S. N. M.). 



A male from Chateaugay, N. Y., and a female from New 

 Hampshire, (M. C. Z.). 



Laphria index new species. 



Mystax black; pollen and decumbent pile of face silvery; occiput, 

 coxae, pleiuas, fascia on front of thorax, gray to white pollinose, hair 

 where present concolorous. Thorax with a median triangle of pale to 

 reddish golden hair, about as wide of scutellum behind, rapidly narrowing 

 and evanescent anteriorly; remaining pile on disk of thorax consisting 

 of longer whitish, sometimes golden, and shorter black hairs, bristles 

 black. Hair on scutelhun tends to be paler and the marginal bristles 

 are white. Pile of abdomen, except for whitish hairs on sides of first 

 three segments, pale to reddish golden; rather dense in well preserved 

 specimens, but apparently rather easily lost. Hair of legs gray and 

 black. Wings fumose paler toward base. Hypopygium black, black 

 bristled; apical i)rocess somewhat reddish, beveled on outer side, but 

 not twisted, decurved forming with apex of forceps a figure like an 

 opposed thumb and index finger. (Fig. 17). Length 13-18 mm. 



So far I have not found a way of certainly distinguishing the 

 females of this species from the next ; they appear to be the more 

 robust specimens with the golden thoracic triangle more con- 

 spicuous.

Females from North Carolina, Ohio, Illinois and Wyoming 

 may be this or a related species. The Illinois specimen is

 that a specimen in the Museum of Comparative Zoology bears 

 the manuscript name walkeri Loew.
