Explanation of Plate V. 

 A — dorsal view of three larvae of Euclemcnsia basset fcUa (Clemens) 



(about x3) 

 B — dorso-lateral and ventral views of three euclemensid pupae (about 



x3) 



C — dorsal view of imago with wings expanded (about x3), showing 

 the relative and comparative sizes of the wings and the broad 

 fringe of cilia. 



D— lateral view of Kermes pcttiti Ehrh. (about X14), showing oval exit 

 hole of Euclctnensia basscttclla (Clemens). The upper half of 

 this Kermes was pecked away by woodpeckers, leaving the cov- 

 ered "U-shaped" retreat shown in Fig. E. 

 ^E — Kermes petiiti Ehrh. (about xi) in situ on an oak twig; dorsal 

 view of Kermes shown in Fig. D, showing the covered "U- 

 shaped" retreat of a larva of this euclemensid parasite. 



F — aggregation of three infested and one apparently uninfested 

 Kermes (about xio), showing: (c) the silken coverings over 

 exit holes and made by the larvae of Euclemensia hassettella 

 (Clemens) but broken by the emergence of the adults; (m) an 

 adult moth in the act of emerging from her Kermes host. How- 

 ever, this particular one died in the larval retreat, due to the 

 fact that the larva had not cut a large enough exit hole through 

 the body-wall of the host for the imago to escape from. 



H — Kermes pettifi Ehrh. (about xi), showing: (a) group of specimens 

 in Fig. F; and (b) a normal uninfested Kermes. 



A new Species of Copaeodes (Lep.). 



By Henry Skinner. 



Copaeodes chromis n. sp. 



Color of all wings deep chrome. Primaries have a brown border 

 2 mm. wide, which extends from near the middle of the costa to the 

 middle of the inner margin. The stigma is a narrow line at the end of 

 the discoidal and it runs parallel to the outer margin. 



The secondaries have the costal margin brown. 



Undersides same color as above and immaculate except for a small 

 brown spot at the base of the primaries. 



Head, thorax and abdomen deep chrome. Expanse 25 mm. 



Described from one male ( ?) specimen from Colima,; Mex- 

 ico. 



Type in the collection of The Academy of Natural Sciences 

 of Philadelphia.. It resembles procris but the primary wings 

 are more rounded and procris does not have bordered wings.
