Sept., i9i6.] Parker: Sarcophagid^ of New England. 173 



third veins prominently bristly ; costal spine distinct ; section III of costa prac- 

 tically equal to section V ; alulse fringed with hair ; calypters whitish, their 

 margins fringed with white hair. 



Legs. — Dark; tarsi without ventral bands of reflecting hairs; vestiture 

 short except for a few scattered, long hairs on ventral surfaces of middle and 

 hind femora. Posterior trochanter without " brush " ; femur spindle shaped ; 

 anterior face with three rows of bristles, those of intermediate row shortest 

 and not developed distally, those of lower row well separated and present on 

 distal two thirds or thereabout; posterior face with ventral row of long, 

 slender hair like bristles ; tibia straight or slightly curved ; tarsus not shorter 

 than tibia; fourth segment at least one half fifth. Middle coxa with a single 

 row of bristles, but there may be a few others anterior to it dorsally ; femur 

 with a complete anterior ventral row of bristles, posterior ventral row lacking 

 or represented by long, well separated hairs ; submesotibial bristle very strong. 

 Ventral face of anterior coxa with an irregular row of bristles at each side 

 only. 



Chaetotaxy. — Bristles stout and prominent. The hinder two pairs of an- 

 terior dorsocentrals almost as strong as postsuturals ; two pairs of acrostichals, 

 presutural pair absent ; inner presuturals absent or very weak ; three pairs pos- 

 terior dorsocentrals of about equal size ; prescutellar acrostichals present but 

 weak as compared to other bristles ; scutellar apicals absent ; three sterno- 

 pleurals ; lower sterndpleura with bristles only. 



Abdomen. — Rather short; depth almost equal to width so that it appears 

 somewhat cylindrical, outline more elliptical than oval ; nota clothed dorsally 

 and ventrally with short reclinate bristles. Ventral plates as a whole with 

 their sides converging posteriorly, sides of second and third distinctly rounded; 

 vestiture hairy, that of first and second long, that of third shorter but erect. 



Chastotaxy. — Second segment usually with a row of weak, slender, de- 

 cumbent marignals, sometimes two at center may be stronger and more erect ; 

 third with a complete marginal row dorsally and laterally or dorsally with only 

 two marginals at center ; fourth with a complete row ending ventrally at third 

 notum. 



Genital Segments. — Prominent ; large, abruptly terminating the abdomen 

 and occupying to its fullest extent cavity of fourth notum (see figure). First 

 (g. s.i), pollinose to varying extent, sometimes entirely so with reflecting colors 

 of abdomen but usually posterior portion dull orange, posteriorly its vestiture 

 longer than that of second segment, viewed from behind it presents a very 

 large, slightly convex surface abruptly rounded forward dorsally (the segments 

 being in their normal position), marginal bristles absent. Second (g. s.2) seg- 

 ment (examined in similar position) appears like a slightly raised dull orange 

 disk, anal area small. Forceps short, base without upward flap-like extensions, 

 its vestiture not longer than that of second segment ; bieyond base prongs be- 

 come abruptly slender and very small, thence attenuated to tips, both together 

 looking like the end of a large blunt needle, their outline in profile sinuate, 

 the anterior edges hairy. The dull orange lamellae of fourth ventral plate 

 may show beyond edges of fourth notum.
