ART. 17. NORTH AMERICAN PHOROCERA ALDRICH AND WEBBER. 79 



The species has been reared from Lophyims^ species and Pyrausta 

 penitalis Grote by Forbes (Townsend) ; and from Cossula magnifica 

 Strecker (Brimley) ; localities Illinois and North Carolina. 



PHOROCERA TEXANA, new species. 



Essentially the same as Phorocera comstocki, except that the ab- 

 domen is black, thickly covered with gray pollen and devoid of defi- 

 nite pattern; the fourth segment is entirely gray pollinose. The 

 front in the male is somewhat narrower, about 0.36 the head width 

 (average of three, 0.36, 0.35, and 0.375) ; in one female 0.37. 



Described from eight males and two females, bred in three lots 

 from Melitara species in Opuntia; five were reared at Victoria, 

 Texas, by J. D. Mitchell, one at Corpus Christi, Texas, by F. C. 

 Pratt, and four at Uvalde, Texas, by J. C. Hamlin. Emergence in 

 October and November.

Front of male 0.314 of the head width, golden pollinose, the sides 

 with man}' fine black hairs, face golden pollinose, the ridges bristly 

 nearly to the base of antennae; bucca about one-fifth the eye height; 

 palpi yellow; antennae blackish, as long as the face; the third joint 

 of male six times the length of second, arista thickened on the basal 

 fourth, the penultimate joint short. Thorax black, gray pollinose, 

 marked with four black vittae; four dorsocentral macrochaetae ; 

 scutellum black, gray pollinose, sometimes slightly reddish at tip, 

 bearing three long and one shorter upturned pair of apical bristles;

 anal segment yellowish ; no discal macrochaetae present ; first and 

 second segment with one pair each of median marginal bristles, the 

 third with a marginal row and the fourth thickly beset with bristles 

 of various lengths, one row in particular near the apex of segment

Redescribed from a male specimen, labeled " Guanajuato, Mexico." 

 Other specimens determined by Coquillett as this species show con- 

 siderable variation. A female, from Louisiana, agreesoiuite well in 

 main part, but has the sides of front bare outside of the frontal row. 

 The antennae are shorter than face, third antennal joint four times 

 the second, front 0.340 of the head width, ovipositor visible and shows
