throughout; the ord discoiilal is of equal robustness with the Istj the 4th 

 or stigiual vein is of equal robustness with the 1st and does not taper; in 

 the hiud wing the apex of the 2nd discoidal is nearly twice as far fi'oni 

 the apex of the rib-vein as it is from the apex of the 1st discoidal. 



Length to tip of wings .09 — .12 inch; expanse .20 — .25 inch. Four- 

 teen specimens. The stigma is three times as long as wide, very acute at 

 the basal end. and not materially wider than the costa. Found winged 

 specimens May 25th in company with many larvae and pupas, and obtain- 

 ed others in the course of June, all in the nests of the same yellow ant 

 before mentioned. A specimen of the woolly secretion of the larvae which 

 I have preseiTcd appears under the lens like cotton wool, but at least ten 

 times as fine and snowy-white. From the nests of the same ant I have 

 obtained the rare ceopJti/Uus mom'Iis Lee, (pselaphidae,) hrtsen'us hrunni- 

 pennis Randall, (histerid^e,) and an undetermined species of Phthora, (ten- 

 ebrionidai).

Differs from P. raryiefoltx, Fitch as follows: — The size is larger; the 

 abdomen is not pale but blackish; the whole costa is pale brown, the stig- 

 ma with a yellowish tinge; the 3rd or stigmal vein is not abortive at its 

 origin; the 2nd or middle vein is not parallel with the 3rd but each of 

 the two is slightly convex towards the other, as is also the case in P. raryse- 

 folise^ although overlooked by Dr. Fitch; neither is the oi'igin of this mid- 

 dle vein "abortive for a short distance," so far as I have observed, in either 

 of these two species, as stated of P. rarysefolipe by the same author. The 

 hind wings have the same "angular point" or hook on their anterior mar- 

 gin, used to attach them to the thickened spot on the posterior edge of the 

 front wing, which I have found in every Aphidian species known to me. 

 Length to tip of wings .07 — .08 inch. Three specimens. The anten- 

 nae are scarcely longer than the head and I am unable to distinguish the 

 joints. The stigma is about three times as long as wide, straight pos-
