THE CANADIAN ENTOMOLOGIST 363 



or three bristles proximally; posterior face with ventral row of 

 long, well separated bristles on proximal half or slightly more. 

 Anterior and posterior ventral rows of middle femur complete, 

 but bristles weak and inconspicuous distally: submesotibial 

 bristle very strong, sometimes a short bristle just above it. 



Chcetotaxy — Anterior and anterior postsutural dorsocentrals 

 shorter: usually three sternopleurals, sometimes four on one or 

 both sides: lower sternopleura with a single row of bristles, often 

 with several others iust anterior to its lower part, otherwise clothed 

 with hair. 



Abdomen — Oval; vestiture practically throughout of short, 

 reclinate bristles. 



Genital Segments — Slightly protuberant, visible only from 

 beneath or sometimes bristles of first segment may be seen from 

 above. The two broad lateral lips of the first genital segment 

 distinctly separated dorsally, their edges usually abruptly turned 

 backward and fringed with bristles that decrease in length and si/e 

 ventrally, dull orange, often yellowish poUinose, spiracles nearer 

 to anterior than posterior margin. Fifth segment not discernible 

 as such, its spiracles rarely visible and apparently open through 

 lips of sixth segment (first genital). Ventral plates of genital 

 segments concealed. 



Described from 15 males and 12 female specimens, 62 others 

 examined.

The fact that the vestiture of the anterior portion of the 

 cheeks is black and that the posterior is white together with the two 

 beards of equivalent value on the posterior tibiae is sufficient to 

 distinguish males of this species from others known in New Eng- 

 land at least. Sarcophaga hcemorrhoidalis Meigen and 5. dalmatina 

 Schiner while very distinct might possibly be confused with it 

 by one not familiar with the group; the above characters will 

 immediately differentiate them. Females of both these species
