A BRIGHT RED PARASITE OF COCCID.E. 



BY T. D. A. COCKERELL, N. M. AGR. EXP. STA, 



Aphycus Howardi, n. sp. — ^. Length about i mm.; entirely 



bright scarlet, except the brown antennal club, sage-green eyes, and 



white tarsi ; with the apical portion dusky. Wings dull hyaline, with a 



dark cloud ending at stigmal vein, whitish just beyond and hyaline at 



tip. Scape not dilated, club about or almost as long as the four joints 



before it. Mesonotum and scutellum with numerous short white hairs, 



mesonotum with no naked spots ; mesopleura very delicately shagreened, 



with no longitudinal impressions. 



Hab. — Mesilla Park, New Mexico; bred from Eriococctn Tinsleyt, 

 CkW., on Atriplex canescens ; collected by Prof J. D. Tinsley. Emerged 

 August 6th, and some days following. The colour of this beautiful little 

 Aphycus is just like that of Perdita luteola when reddened by cyanide, 

 and I should certainly have considered it as due to the same cause, had I 

 not seen the species alive. The original type is now in the U. S. Nat. 

 Museum ; two or three others were bred after the description had been 

 written. A. Howardi is named after Dr. L. O. Howard, in recognition 

 of his valuable work on the parasites of Coccidse. He has now in press 

 a revision of the genus Aphycus, and the present insect was found just too 

 late to be included in it. He has very kindly informed me that it is 

 distinct from all the species known to him or published by others, and 

 has given me some notes on its specific peculiarities.
