Mystax, facial and occipital pile, hair of coxae and legs, two tufts 

 on each side of thorax, two on disk, margin of disk of thorax (broadly 

 interrupted anteriorly, narrowly so posteriorly) and dense pile of

 are dark reddish and a little hair beneath mystax is blackish. Body 

 surface piceous where exposed, contrasting strongly with the yellow 

 pile; integument of legs yellow. The disk of thorax, except for yellowish 

 areas mentioned, and the scutellum are covered with short black pile.

 straight, apex on inner side as seen from above, rounded angulate,

Kertesz puts* Laphria saffrana in the genus Dasyllis and 

 the genital forceps, admittedly are somewhat similar to those 

 of species of that genus. (See Figs. 24, 25). L. saffrana does 

 not have the Dasyllis habitus however, which is chiefly due 

 to abundant, long, spreading pile, in large areas of strongly 

 contrasting colors. The short crisp pile of saffrana seems to 

 ally it more with the species of Laphria.
