A Classification of Lepidopterous Larvae. 209 



serial order. Strictly the Tineiua larva? are more specialized than 

 those of the two next families, and should follow them. 



Family Gelechiidae. 

 Depressaria heracliana DeGeer. 



The tubercles are situated in large, polished, black corneous areas, 

 and the setae are aborted, except subventrally. The arrangement is 

 normal ; iv and v are closely approximated, and arise from a single 

 area, while the setae of vii are gathered together on a single black 

 area, forming a rather distinct wart. There is a single cervical 

 shield, and a distinct suture between abdominal segments 9 and 10 



Family Elachistidae. 



Antispila nyssaefoliella Clemens.' 



There is a single cervical shield, a small projecting anal plate, 

 and the body is flattened. A few setae remain subventrally, but 

 the tubercles have disappeared, as have also all the feet. 



Family Lacosomidce. 



In 1893^ I attempted to show that this group must be separated 

 from the Psychidae and the Drepanidae, with both of which it had 

 previously been united. I was unaware at the time that C. Plotz^ 

 had already established the family under the name Perophoridte ; 

 but the name is preoccupied. A little later Dr. Packard* recognized 

 this difference so far as to create a subfamily of the PsychidEe, where 

 he transformed my term into Lacosominae. In the same year 

 (1893) Prof. Comstock's article appeared, in which the Lacosomidae 

 (^ Perophoridas) are included among the Saturnina, in the highly 

 specialized group of Frenulum Losers. I had never ^en the larvae; 

 but, through the kindness of Dr. Packard, I have now been able to 

 examine both of our species, and Prof. Comstock has given me a 

 Brazilian form. From these larvae I conclude that this family 

 belongs to the Microlepidoptera, as here set forth, a conclusion 

 which is contrary to any previously offered. 



1 Dr. J. A. Lintner has kindly determined this larva for me.
