bLackish, the third joint twice the .second, extending 

 three-fourths of the way to the vibrissas, which are at 

 the oral margin; arista witli rather short plumosity 

 for half its length; palpi and proboscis black, ordi- 

 nary; bucca slightly over half the eyeheight, with 

 black hairs which extend behind the metacephalic 

 suture ; only a few pale hairs around the neck, back of 

 head otherwise covered with black hair. 



Thorax with gray pollen and the usual three to 

 five black stripes, the middle one of which is quite 

 narrow; the submedian gray stripes are divided for 

 two-thirds of their length; ps dc four; ant acr two 

 very large pairs ; prsc one ; stpl three ; scutellum with 

 two marginals, one rather large preapical; upon the 

 apex are several long hairs, but they do not appear to 

 be arranged like the usual small apical bristles. 



Abdomen apparently tessellated but not in very 

 good condition to describe. First and second seg- 

 ments with only laterals; third segment with a pair 

 of depressed marginals; fourth with the usual mar- 

 ginal row of about a dozen; fifth sternite widely ex- 

 cised, not distinctly visible in the specimen; first seg- 

 ment of hypopygium red, its base blackish, of peculiar 

 shape, being turned under at the apex so as to have 

 a pronounced hump beyond the middle ; it has numer- 

 out long erect hairs, rather stout ; second segment red, 

 subshining, with rather coarse erect hairs: forceps 

 minute, shining red, not divergent, straight, not taper- 

 ing, inclined backward at an appreciable angle, the 

 apex obliquely truncate so as to be shorter on the 

 front side, where there is a minute point; accessory 

 plate comparatively large, so that it has to be removed 

 in order to get a side view of the remaining organs; 

 it is excised at the apex, having two rather sharp 

 points. The shape is indicated by dotted lines in 

 the sketch. Posterior clasper yellow, rather wide at 

 base, broadly excised on front side toward apex, which 

 is long and curved and very slender, a stout hair arises 

 from the basal part of the excision; anterior claspers 

 yellow, slender, the tip with an accessory point below ;
