Mar. i, 1921 Lepidoptera Likely to Be Confused with Pink Bollworm 817 



body tubercles inconspicuous, chitinized areas about them unpigmented 

 except around setae IP and II b on mesothorax and metathorax where 

 they are pale brown; body hairs whitish yellow, rather long;*' abdominal 

 crochets yellow, 40 to 44, unevenly biordinal and in a complete circle; 

 anal fork absent; head pale yellow, the more heavily chitinized parts of 

 trophi lighter brown ; ocellar pigment black, continuous under the ocelli; 

 length, full grown, 7 to 7.5 mm. 



The pupa is the typical short, squatty stenomid form; smooth, without 

 armature or processes of any kind except the very short, inconspicuous 

 primary setae and a pair of minute spines on the anal rise; seta III on 

 abdominal segments well forward of the spiracle; spiracles distinct and 

 rather large, very slightly produced ; wings, antennae, and metathoracic 

 legs extending to anterior margin of fifth abdominal segment; antero- 

 ventral margins of fifth abdominal segment curved around the edge of the 

 wing tips; labial palpi very small, not reaching to proximo-lateral angles 

 of maxillae; eighth, ninth, and tenth abdominal segments considerably 

 reduced and sharply tapering; prothorax broad, nearly one-third the 

 breadth of mesothorax; proleg scars distinct ; length 4 to 4.5 mm; width 

 1.5 to 2 mm. 



Immature larvae were collected by Diven in late January, 191 9, and 

 feeding larvae as late as April 1, 191 9; from the latter, moths issued from 

 April 17 to 26 of the same year. 



The male genitalia of the moth are figured in Plate 95, B, C.

Feeding in dry okra pods, in the seed pods of Hibiscus, and in old 

 or diseased cotton bolls we often found associated with Pyroderces rileyi 

 a dirty brownish larva with a glistening black head and thorax, spin- 

 ning a thin web in the seed pods within which it fed and pupated. A 

 number were collected at various places in Chambers County (Smith 

 Point, Point Bolivar, and South Bayou) and from these were reared a 

 number of adults agreeing in genitalic and other characters with authen- 

 tic reared specimens of Zenodochium citricolella Chambers in the United 

 States National Museum. The species is a scavenger and probably a 

 very general feeder, as it was originally recorded from dried oranges 

 and is to be found in almost any dry or diseased malvaceous seed pod. 



Figures of the male genitalia of the moth are given in Plate 98, A-C.
