Various individuals of this species from Falls Church, Xiv- 

 ginia, show cell R4 either wholly absent, partially enclosed, or 

 totally enclosed by traces of veins, as in Nomiaephagus. 



I have examined the type of henshawi Melander in the Museum 

 of Comparative Zoology, and find it identical with this species. 

 The posterior ocelli are not rudimentary, as stated in the descrip- 

 tion of henshawi, but in the type specimen are as large as the 

 anterior one, concealed somewhat by an elevated portion of the 

 vertex, their plane being raised almost to the vertical. As in 

 the type of henshawi, the mandibles of many specimens are so 

 worn as not to show three teeth, while in others the two inner 

 ones are quite distinct. 



I have not seen the type of daeckei Rohwer, but the only differ- 

 ence indicated in its description is in the amount of white pubes- 

 cence on the abdomen. A series of specimens of geryon shows 

 almost complete replacement of the white pubescence of the 

 dorsal segments, including the apical fringes, by black, as de- 

 scribed for daeckei. 



It is possible that geryon is the male of siniillima.

Pseudomethoca (Nomiaephagus) oceola (Blake), cf. 



This seems to be a rare Lower Austral species. The Massa- 

 chusetts records given by Melander prol)ably apply to sanbornii 

 or another species. It is probal)ly the male of either hippodamia 

 or aetis.
