Mar. i, 1921 Lepidoptera Likely to Be Confused with Pink Bollworm 827 



The pupae have two rows of strong spines on the dorsum- of several 

 of the abdominal segments as in the Tortricidae, but the wings are 

 narrow and pointed, the maxillary palpi are large and conspicuous, and 

 the thoracic spiracle is normally well developed; thus they are dis- 

 tinguished readily enough from pupae of the latter group. 



FAMILY PTEROPHORIDAE 

 EDEMATOPHORUS VENAPUNCTUS, N. SP., BARNES AND LINDSEY * 



During April and May, 191 9, Mr. B. L,. Diven reared eight specimens 

 of a pterophorid moth from larvae feeding on the leaves of a composite 

 at Brownsville, Tex. These were referred to Mr. Lindsey, who determined 

 them as Oedematophorus venapunctus, an unpublished species, which he 

 and Dr. Barnes had recently described from collected material. 



The species is not a malvaceous feeder and has no special interest here 

 apart from the rearing record and the structural peculiarities of the larva 

 and pupa which, while strikingly modified in this particular form, will 

 serve, nevertheless, to exemplify the family. 



The pterophorid larvae have only two setae on the prespiracular shield 

 of the prothorax and setae IV and V approximate on the proleg-bearing 

 abdominal segments, as in the Pyralidae with which they are affiliated. 

 They have, however, in distinction from the Pyralidae proper, long stem- 

 like prolegs and a greater or less development of secondary setae. The 

 crochets are also peculiar, being uniordinal, few in number (6 to 8 in the 

 genus Oedemataphorus), and arranged in a quarter circle opening 

 outwardly. In O. venapunctus the secondary hairs are confined to a row 



1 Inasmuch as the foregoing name was desired for this paper in advance of their proposed revision of the 

 Pterophoridae Drs. Wm. Barnes and A. W. Lindsey have kindly furnished the following description: 



Oedematophorus venapunctus, n. sp., Barnes and Lindsey. 



Head whitish ochreous between the antennae, elsewhere light brown. Antennae and palpi pale brown- 

 ish ochreous, almost white, the latter short, oblique or porrect. Thorax and legs of the same shade of pale 

 brownish ochreous, the fore and middle legs tinged with brown inside. Abdomen similar both above 

 and below, with a fine, browa, middorsal line. 



Primaries concolorous with thorax, darker toward costa, especially in first lobe, though this shade is 

 scarcely evident in some specimens. Just before and below the base of the cleft is a small blackish brown 

 spot, isolated except in our darkest specimen, in which it is continued obliquely toward the costa by a 

 faint dark shade. In the outer margin of the second lobe there are four short, dark dashes on the tips 

 of the anal, cubital, and third median veins. These are very faint in some specimens. A similar but 

 heavier spot occurs on the inner margin of the first lobe a short distance before its apex at the tip of the 

 fifth radial. Two vague dots sometimes appear on the costal margin of this lobe, one just before the apex 

 and the other almost opposite the one on the inner margin. Fringes concolorous, slightly darker toward 

 the apex of the wing and with their bases slightly paler. Secondaries somewhat paler than primaries and 

 with a more grayish tinge. Fringes concolorous with slightly paler bases. 



Expanse 15 to 18 mm. 



Described from the following series: Holotype male, Brownsville, Tex., March; paratype male, same 

 locality; allotype and six paratypes females, San Benito, Tex., March and April. (Collection Barnes). 



Paratype male, Brownsville, Tex., March, and paratype female, from San Benito, Tex., April, in United 

 States National Museum, type Cat. no. 23495. 



This species appears to be allied to Oedematophorus paleaceus, O. stramineus, O. kellicctti, and related 

 species. It differs from the first two in the presence of the terminal dots and from the last two in that the 

 dot in the disc of the primaries is not contiguous to the base of the cleft. The form of the male genitalia 

 also differs from that of any related species known to us. We have been unable to place it as a described 

 Mexican or Central American species.
