Mar. i, i93i Lepidoptera Likely to Be Confused with Pink B oil-worm 835 



grown, a hole which reminds one very much of the exit hjle made by a 

 pink bollworm. 



The larva itself looks nothing like -any of the others here treated. 

 It is spindle-shaped, sharply tapering at each end, broad in the middle 

 in proportion to its length, with a small head, the body covered with fine 

 stiff secondary hairs, and greenish yellow in color. 



In addition to cotton we find it frequently on okra, Kosteletzkya spp., 

 Malvaviscus drummondii, and Hibisctis spp. On these it fed on the 

 seeds, boring into the seed pods, or upon the blossoms. 



The table of larval characters will serve to place the forms here treated. 

 The characters given are not to be understood as diagnostic in all cases. 

 In the Cosmopterygidae, for example, seta I is often as far from III 

 as it is from II as in the Gelechiidae or the Oecophoridae. There are 

 also a few exceptions to the gelechiid character (the remoteness of 

 epicranial seta V from A 3 ). The characters hold, however, for all the 

 species here treated occurring on Malvaceae. 



Characters of larva likely to be confused with the pink bollworm 



1. Body depressed and spindle-shaped, covered with, secondary setae . . Lycaenidae. 

 Body otherwise 2 



2. Setae IV and V on proleg-bearing abdominal segments closely approximate . . 3 

 Setae IV and V on proleg-bearing abdominal segments well-separated 13 



3. Prespiracular shield of prothorax bearing two setae only 4 



Prespiracular shield of prothorax bearing three setae 5 



4. Prolegs long and slender; body of larvae normally with one or more second- 



ary setae Pterophoridae. 



Prolegs otherwise ; body with only primary' setae Pyralidae. 



5. Body with one or more secondary setse Ethmiidae. 



Body with only primary setae 6 



6. Ocelli I to IV grouped together, forming a trapezoid; ocelli V and VI fairly 



close together but well-separated from the other four Aegeriidae. 



Ocelli otherwise 7 



7. Paired dorsal setae II on ninth abdominal segment closer together than 



paired I on dorsum of eighth abdominal segment; usually on a single 



chitinization 8 



Paired dorsal setae II on ninth abdominal segment at least as far apart as 

 paired I on eighth abdominal segment and not on a single chitinization . . 9 



8. Setae I and III closely approximate on ninth abdominal segment 10 



Setae I and III not closely approximate on ninth abdominal segment Tortricidae. 



9 . Epicranial seta L, 1 remote from A 3 (farther from A 3 than A 3 is from A 2 ) Gelechiidae. 

 Epicranial seta L 1 approximate to A 3 , at least no farther from A 3 than A 3 is 



from A 2 11 



10. Seta IP on prothorax higher than I a Cosmopterygidae. 



(in part : Pyroderces rileyi) . 



Seta II a on prothorax not higher than I a Olethreuttdae. 



Phalonhdae. 



11. Prothoracic legs very close together, coxae touching BlastobasidaE. 



Prothoracic legs appreciably separated 12
