of posterior .surface. I'.suully only hii.se of forcep.s visil)le, tliis with 
short upward flap-like extensions that bear long, fine, curly hair. 
Genitalia. — Penis divided into distinct proximal and distal por- 
tions; latter with a forward extension from its ba.se as long as main 
part of penis; when genital segments are pulled out, this is seen extend- 
ing diagonally forward and downward ; posterior claspers stouter and 
longer than anterior; accessory plates prolonged into prominent 
linear processes. 
Described from twelve specimens; about forty others examined.

In small specimens the bearded character of the posterior femur 
and tibia is much less pronounced. It should also be noted that when 
the genital segments are pulled out the ventral parts of the fourth 
notum tend to regain their normal position and specimens caught in 
this condition do not appear so much enlarged at the end of the abdo- 
men as is usually the case. This applies to the other species as well. 
The various processes and con\olutions of the penis as shown in the 
figure will probably not be readily seen, but a general correspondence 
in shape is all that is necessary for identification by means of the geni- 
talia. Size in itself is distinctive, and the forward extension is not 
bent backward as in the two species which follow. The middle 
bristle of the three sternopleurals tends to be very weak and will 
probably be found wanting in some specimens. In such cases, care 
should be used not to confound it with hisriosa. 
I have seen specimens in which the legs were partly fulvous colored, 
but this undoubtedly is an abnormal condition. 
The name of the species was suggested by the broad ventral plates.
