SARCOPHx\GA AXl) ALLIES 33 



The described male is a little darker in color than 

 the female, and had not the latter been a^ ailable for 

 comparison I would have hesitated to identify it as 

 this species. 



Type.— Female, in the U. S. X. M. 



No. 5. Johnsonia setosa n. sp. 



Male. Front .319 of head (average of two,^ — 

 .317 and .321); strikingly similar in all structural 

 characters to elcgans, but decidedly black throughout, 

 with only the following parts yellow: tip of second 

 antennal joint and basal half of the third; apical half 

 or more of the fourth abdominal segment; and parts 

 of the hypopygium and genitalia. 



In the cha^totaxy there are a few slight differ- 

 ences. The back of the head has four irregular rows 

 of black hairs ; the prescutellars are distinct but small ; 

 the second abdominal segment has a fairly complete 

 marginal row of bristles, the median pair, however, 

 are the largest. 



The abdomen, besides being quite black in ground 

 color is in some lights completely pollinose and hardly 

 tessellated ; in other lights, however, it is largely shin- 

 ing. 



Both segments of the hypopygium are infuscated 

 above, but red on the sides; the forceps and claspers 

 seem exactly as in elegans, the penis apparently dif- 

 fering a little apically. But the genitalia of one speci- 

 men have been destroyed, and those of the other are 

 not in good condition for exact study. 



Length 51/. mm.

Holotype.— Male, Xo. 20486, U. S. N. M.; 

 paratype in author's collection.
