The larva is yellowish white, longitudinally striped with wine-red; 

 one rather broad middorsal stripe dividing into two thin parallel stripes 

 from the second abdominal segment forward; one moderately broad 

 subdorsal and one lateral stripe extending from hind margin of prothorax 

 and fusing on the ninth abdominal segment and forming on the tenth 

 a dark border around the outer edge of the anal shield; in the area of 

 seta VI a similar narrow sublateral stripe ; head and thoracic shield pale 

 yellow; crochets of prolegs 28 to 34, biordinal and arranged in a complete 

 circle; anal prolegs with a conspicuous blackish red chitinized spot on 

 caudal side; anal fork rather large, 2-pronged; full-grown larva 8 to 

 8.5 mm. long. 



The species is close to and strikingly resembles Gelechia trophella 

 Busck, from which, however, it is easily distinguished by the male 

 genitalia. The structural differences are shown in Plate 93, A and B, 

 and in Plate 94, C-G. 



The larva is not in any way to be confused with the pink bollworm, 

 from which it differs strikingly in superficial appearance. It resembles 

 somewhat the larva of Gelechia hibiscella Busck but is separable from 

 that species by food plant and structure. In G. neotrophella the anal 

 fork is 2-pronged, while in G. hibiscella it has from 6 to 8 distinct prongs. 

 In the latter, also, the dorsal stripes are nowhere fused.

Telphusa mariona, n. sp. 



Antennae black. Palpi cream-color, shading to white on upper side of second 

 joint; apical half of third joint and upper side of basal joint black. Face white. 

 Head and thorax cream-yellow. Forewiugs glossy black with two conspicuous 

 cream-colored spots; one, a short triangular dash on outer third of costa; the other, 

 an irregular spot of about the same size on dorsum just beyond middle; in some speci- 

 mens two or three minute and obscure patches of white or cream-colored scales along 

 termen; cilia blackish. Hindwings and cilia smoky fuscous. Legs black, ringed at 

 outer margins of the joints with cream -yellow or white. Male genitalia of type as 

 figured (PI. 94, A, B). Alar expanse 9 to 11 mm. 



Habitat. — Brownsville, Tex. (J. D. More and H. C. Hanson). 



Food plant. — Abutilon incanum. Larva a leaf-folder. Also taken on Abutilon 

 berlandkri, Malvastrum sp., Wissadula sp., and Sida sp. 



Type. — Cat. No. 23740, United States National Museum. 



Described from male type and 25 male and female paratypes reared 

 from larvae collected in late March and early April, 191 9, on Abutilon 

 incanum. Moths issued from middle of April to middle of May, 191 9. 



Larva, full-grown, 6.5 to 7 mm. long; slender. Body yellowish white 

 with a subdorsal and a lateral longitudinal row of large red blotches and 

 a longitudinal row of smaller red spots on the level of seta VI and just 

 anterior to that seta on each segment; on the eighth abdominal segment 

 the paired subdorsal spots are fused and on abdominal segment 9 the
