The larva is easily distinguished from Pyroderces rileyi and the other 

 lepidopterous cotton feeders by the structural characters shown on 

 Plates 102, 104, and 105. The most striking features are the oval chiti- 

 nized plate on the submentum, the nearly complete fuscous circle sur- 

 rounding the chitinization of tubercle III on abdominal segments 1 to 

 7, and the typical blastobasid arrangement of the prothoracic legs (Pi. 

 105, I), set very close together with the coxal lobes touching each other. 



The species probably has several generations a year. Larvse collected 

 in August, 1 91 8, produced moths in that month and throughout Sep- 

 tember. Others collected during November and December produced 

 moths the following April. 



HOLCOCERA OCHROCEPHALA DIETZ 

 (PL. 98, D-F) 

 Holcocera ochrocephala Dietz, 1910, in Trans. Amer. Entomol. Soc., v. 36, p. 31-32. 



A large series of moths were reared during February and March, 191 9, 

 from larvae collected December, 1918, in imperfectly opened and weevil- 

 infested cotton bolls at Brownsville, Tex. They agree with the descrip- 

 tion and the single female paratype of Dietz's species in the United 

 States National Museum, and I have no hesitation in so determining 

 them. The larval habits are the same as those of Zenodochium citrico- 

 lella. There probably has been some confusing of our material, as all 

 the larvae we have associated with the H. ochrocephala adults are iden- 

 tical with those of Z. citricolella. Probably, since the two species work 

 together in the same way and are superficially alike, the larvae of one 

 species was preserved and that of the other reared. It is extremely 

 unlikely that there should be two blastobasids in different genera with- 

 out a single structural difference in their larvae. 



The male genitalia of the moth are figured in Plate 98, D-F. 



HOLCOCERA CONFAMULELLA, N. SP. 



(PL. 99, C) 

 Holcocera confamulella, n. sp. 



Antennae deeply excised above basal joint and with truncate scale tuft; very 

 weakly ciliate. Palpi grayish ochreous, dusted with fuscous on outer sides. Face 

 grayish ochreous, vertically banded with fuscous. Head and thorax grayish white 

 mixed and suffused with fuscous scales. Forewings grayish white, suffused and 

 mottled with fuscous, the fuscous scaling giving the outer two-thirds of the wing a 

 distinctly gray-brown appearance, darkening into an ill-defined, outwardly angulate 

 antemedial fascia bordering a grayish basal patch and forming an irregular, broken, 

 and obscure vertical fascia beyond the middle; along the termen a few barely dis- 

 tinguishable fuscous spots; cilia grayish white. Hindwings very narrow, pale smoky 

 fuscous; cilia paler, tinged with ochreous. Legs whitish ochreous on inner sides; 

 the outer sides fuscous, spotted with white on tibiae and ringed with white or whitish 

 ochreous at ends of joints. Male genitalia of type figured (PI. 99, C). Alar expanse 

 14 to 15 mm.
