ately slender abdomen and a less developed hypopygium. As 
to the coloration of the legs, those of Walker’s type may have 
been bleached or faded, leaving only the base of the femora 
black. I am inclined to consider albofasciatus rather than 
atramontensis as the synonym. 
P. translatus Walker. 
Evidently belonging to the subvirescens group, in which 
case a very close examination is necessary to establish its 
true position, but it will probably prove to be subvirescens 
[.w. The type is a male with the head missing. 
P. subvirescens Loew. 
Upon examining a female from Opelousas, La., June, °97, 
determined by Dr. Hough as this species, the following are 
noted: Similar in most respects to similis Hough, as I have 
described (7), but the abdomen is more cylindrical, not ap- 
parently ovate or flattened on the dorsum, and the incisures 
are not constricted; bare, and the black hairs not noticeable 
apically ; femora and trochanters without basal bristles; other- 
wise I can see no difference. There may be a possibility that 
in associating the sexes of these species in my previous paper 
I have transposed the males or females of this species and 
similis, if any importance can be placed upon the bristles at 
the base of the femora. Subvirescens male has these present, 
but they are weak or absent in the male of similis, according 
to my determinations, while with the females, as I have them 
distributed, it is just the reverse. 
P. appendipes Cresson. 
One female. Tifton, Ga., Sept. 30, ’96. 
This specimen agrees with the typical description of the 
female of this species, except that the abdomen here is not 
quite shining, seeming to be minutely granular. This is 
cne of the difficult subvirescens-group, and it is almost im- 
possible to satisfactorily determine some of the species, 
especially those without the peculiar characters which many 
possess, and it will take large series and much study to straight- 
en out this group especially as to the females.
