INSECUTOR INSCITI^ MENSTRUUS 47 



whitish, edged by black without, erect to median vein, then 

 oblique inwardly to costa; discal dots conjoined into a bar, 

 followed by irregular black scaling on the bases of the discal 

 nervures and by orange or black scales below in the subme- 

 dian space ; outer line whitish, edged by black on both sides, 

 more diffusely outwardly, finely denticulate and sharply incised 

 opposite cell ; a black terminal line ; fringe pale gray at the base, 

 darker outwardly. Beneath, a long pencil of pale yellowish 

 hairs concealed in a fold along submedian space. Hind wing 

 whitish, translucent, gi^ay along costa ; a dark gray terminal 

 line ; fringe interlined with gray. Expanse, 20 mm. 



Female. — Similar, but with less contrasting shades, uniform 

 gray, the lines black, the yellowish shades usually converted 

 into gray, though occasionally distinct. Expanse, 20-21 mm. 



Type, male. No. 21058, U. S. Nat. Mus., selected from 26 

 males and 35 females, bred from larvae in large, conspicuous, 

 unsightly nests on a bush growing rather commonly in the 

 wild country, New Providence Island, Bahamas, February and 

 March, 1915 (H. G. Dyar). 



The larva is brown with faint longitudinal stripes, a broad 

 subdorsal one being distinct. Tubercle iib on joint 3 and iii 

 on joint 12 are much enlarged. 



A detailed description of the setal pattern is appended, pre- 

 pared by Mr. Carl Heinrich, who has lately made a special 

 study of the matter. 



The samples which I preserved of the food plant for de- 

 termination have been lost or mislaid, so its name cannot be 

 stated at this writing. A native of the island called it "wild 

 cassava." 



This Phycitid occurs also in Cuba. I have 3 males and 16 

 females taken by Mr. Wm. Schaus at Santiago, in June, July, 

 August and October, 1902. The male is more darkly shaded 

 than in the form from the Bahamas, the dark markings ex- 

 tended, reducing the gray ground to one or two patches. The 

 female seems a little brighter than the Bahamas form, the 

 ocherous shade before the inner line being always distinct; 

 but there is no constant difference.
