more or less suffused and mottled with black; ocellar pigment black, 

 continuous under all the ocelli. Full-grown larvae 22 to 23 mm. long. 



The only caterpillar treated in this paper which could easily be con- 

 fused with this species is that of Gelechia neotr Ophelia Heinrich. The 

 latter, however, is at once distinguished by its 2-pronged anal fork and 

 the fusing of the middorsal stripes on most of the abdominal segments. 



GELECHIA BOSQUELLA CHAMBERS 



Gelechia bosquella Chambers, 1878, in Bull. U. S. Geol. Surv. Terr., v. 4, p. 87. 

 Gelechia basquella Busck, 1903, in Dyar, List North Amer. Lep., no. 5729. 



A single moth of this species was reared September 23, 191 8, from 

 Cassia tora infested by larvae of Platynota rostrana Walker, collected at 

 Turtle Bayou, Tex. This species is not a malvaceous feeder and is only 

 mentioned here on account of the similarity of its larva to those of two 

 other species treated in this paper, Borkhausenia diveni Heinrich and 

 Noctuelia rufofascialis Stephens. It is very strikingly colored, the three 

 thoracic segments being a bright wine-red while the rest of the body is 

 green. The head, legs, thoracic shield, and body tubercles are black. The 

 red coloring of the thoracic segments, however, is not continuous as in 

 the two species just mentioned but is broken on the anterior portion of 

 the meathtorax by a broad encircling band of the greenish body color. 



A detailed technical description of the larva is given by Dyar in Busck's 

 revision of the American Gelechiidae. 1 



GELECHIA NEOTROPHELLA, N. SP. 



(PL. 94, c-g; 105, h) 

 Gelechia neotrophella, n. sp. 



Antennae black. Palpi black, dusted with white. Face black, very slightly dusted 

 with white. Head and thorax black, heavily dusted with white. Fore wings black, 

 marked with overlaid white scales; the white dustings over the black forming an 

 oblique, basal grayish-white patch wider on dorsum than on costa, an obscure, rather 

 broad median fascia consisting of a narrow, oblique median streak clouded with grayish 

 before and behind, and a short white geminate costal dash at apical fourth ; cilia smoky 

 blackish fuscous. Hindwings and cilia pale smoky fuscous, somewhat shaded with 

 black toward apex. Legs black, dusted and annulated with white. Male genitalia 

 of type as figured (PI. 94, C-G). Alar expanse 12 to 13 mm. 



Habitat. — Brownsville, Tex. (Diven and Heinrich). 



Food plant. — Mimosa berlandieri. Larva a leaf-tier, spinning a tube of silk as it 

 feeds and so binding the leaves together. 



Type. — Cat. No. 23739, United States National Museum. 



Described from one male type and two male and six female paratypes. 

 Two generations were noted. From larvae collected February 3, 191 9, 

 moths issued March 5, and from larvae put in rearing early in May, 191 9, 

 adults emerged toward the end of the same month.
