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 

 Lw. 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 

 one of the difficult subvir esc ens-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.
