390 THE GYPSY MOTH. 



Female. Front a little less than one-third of the width 

 of the head, gray pollinose on the sides, the median stripe 

 deep reddish brown or black, broader than the sides, nar- 

 rowed below ; a pair of proclinate ocellar bristles pres- 

 ent; the lateral row of bristles has an outward curvature. 

 Second joint of the antenna reddish; in front somewhat 

 blackish, and with erect bristles ; third joint black, about 

 three times the length of the second; arista thickened at 

 the base, plumose. Sides of the face narrow, bare. Cheeks 

 in width about equal to the length of the third joint of the 

 antennae, with a row of bristles on the inferior margin 

 reaching to the moderately stout vibrissae a little above the 

 oral margin ; bare on the upper part, and with short bristly 

 hairs below. Sides of the face and the upper part of the 

 cheeks reddish in ground color, covered with silvery pubes- 

 cence. Mesonotum gray pollinose, variable, with four nar- 

 row, shining black stripes, the lateral ones interrupted. 

 Scutellum broadly reddish at the apex ; apical bristles long, 

 decussate. Abdomen uniformly covered with gray pol- 

 len, moderately variable in diiferent reflections, the ground 

 color everywhere shining black. Legs yellow ; the front 

 femora in large part and the base of the middle femora 

 black ; all the tarsi blackish. Wings grayish hyaline ; first

 section of the fourth vein shorter than the antepenultimate 

 section. Length, 6-7 mm. 



Three specimens, labelled "Emerged from gypsy moth 

 pupre, Aug. 2021 and 25, 1891." This species is the one 

 which I have commonly identified as C. stabulans Fall., but 

 I have never compared it directly with European specimens. 

 According to Schiner, it has been bred from Bombyx pyri 

 and Lophyrus, and also from various species of Boletus. 



Nlachiptera dispar n. sp. (Plate 53, Figs. 12 and 12a.)
