adding a new genus for the reception of vitinervis to the already too long 

 array of Tachinid genera. 



There are no definite host records for co?ivecta. One specimen, G. 

 M. L., No. 2152E, June 29, '10, bred at the Gipsy Moth Parasite 

 Laboratory, issued from a box of material from which an adult of Tortrix 

 albicomajia Clem, afterward emerged, and it is possible that the Tachinid 

 developed in another larva of the same Tortricid. 



The determinations of the microlepidopterous hosts are by Mr. 

 August Busck, to whom I am much indebted.

BY T. D. A. COCKERELL, BOULDER, COLO. 



Psennliis ( Neofoxia) Towiisendi^ new species. 



Piura, Peru, April 2nd, 191 1. (C. H. T. Townsend). 



? . — Length a little over 6 mm.; black, with the second abdominal 

 segment above and below, and the third (except a broad apical triangle 

 of black above, nearly reaching basal middle) bright ferruginous ; extreme 

 apex of first segment also red at sides ; inner orbital margins strongly 

 convex; face covered with silvery hair; scape black ; flagellum pale, dull 

 reddish beneath, strongly infuscated above, not so robust as in M. Eressoiii 

 Packard ; vertex shining ; cheeks with silvery hair ; mesothorax shining, 

 minutely and sparsely punctured ; scutellum very smooth and shining ; 

 postscutellum with brilliant silvery hair; area of metathorax triangular, 

 with a few ridges, the same kind of sculpture continued on sides of 

 metathorax ; mesopleura with silvery hair ; tegulie pale yellowish ; wings 

 hyaline,, very iridescent ; seco?id r. n, meeting second t. c; submedian cell 

 of hind ivijigs squarely irwicate at end ; knees, anterior tibiae, hind tibiae 

 broadly at base and narrowly at apex, and the tarsi, pale ferruginous ; 

 petiole of first abdominal segment rather short. 



(^ . — Flagellum long and slender ; abdomen long and cylindrical, 



black, with the second segment at apex, and the third and fourth slightly, 

 ferruginous. Easily known from P. inedius Smith by the sparsely punc- 

 tured thorax. 



Type. — Cat. No. 14096, U. S. Nat. Mus. 



[This species belongs to the group of Nearctic species, composed of 

 tibialis Cresson, suffusa Fox and Sayi Rohwer, which is characterized by 

 the narrow pygidium, no tubercle between the bases of the antennae, 

 slender petiole, which is nearly as long or longer than the rest of the first 

 segment. (S. A. Rohwer.)]
