longations [from the same enclosing the narrow median stripe 

 are dark brown ; the yellow part, including the narrow median 

 stripe, looks pollinose by very oblique light, but the dark brown 

 part shows no pollinosity whatever the incidence of light ; a 

 row of marginal bristles larger than those of the first segment, 

 the most lateral of which are not appressed ; also a few small 

 discals toward and on the sides of the segment. Third seg- 

 ment : At first glance seems wholly dark brown, but careful 

 examination reveals a pattern just like that of the second seg- 

 ment, the part which was yellow on segment 2 approximat- 

 ing very closely the color of the dark brown part ; the part 

 corresponding to the yellow part of segment 2 looks pollinose 

 with a favorable incidence of light ; a row of marginal bristles, 

 larger and less appressed than those of segment 2, and two 

 or three discals toward and on the sides. Fourth segment : 

 Wholly dark brown, with a certain amount of pollinose coating, 

 through which, at the bases of the bristles, the ground color 

 shows, producing a speckled appearance ; a complete row of 

 marginal and another of discal bristles. 



The female abdomen is colored throughout like the fourtli 

 segment of the male. Its bristles are like those of the male, ex- 

 cept that there are no discals on segment 2, only one on seg- 

 ment 3, and the row on segment 4 is broadly interrupted in the 

 middle. 



The legs of the male are brownish yellow ; the hind femur is 

 darker toward the apex ; the tibia' are darker than the femora ; 

 the hind tibia' almost brown ; the tarsi are black ; the pulvilli 

 are pale brownish yellow. In the female the femora are blackish 

 brown, the tibiae a little paler, the tarsi black ; I cannot make 

 out the color of the pulvilli. 



This bristles of the legs. — The anterior femur is as usual in 

 this genus. The anterior tibia has the usual preapical of the 

 extensor border; on the same level, just laterad this, on the 

 lateral surface, a second bristle, and close to the apex of the 

 lateral surface a third. Middle femur has the usual anterior 

 median partial row, which is here made up of equal equidistant 

 bristles ; the transverse apical group consists of one bristle on 

 the anterior surface and three on the posterior surface. The 

 middle tibia has no bristles except on the posterior surface, 

 where we find, in the female, two — one at the junction of the
