The conspicuous white patch in the terminal cilia distin- 

 guishes this species from P. erransella Cham, and from P. 

 particornella Busck; from the latter the unicolorous antennae 

 also separate it. It is a much broader winged species than 

 P. erransella; with this exception its structural characters 

 differ in no respect from the type of the genus. 



Psacaphora metallifera Wlsm. 



A number of moths bred from larvae mining leaves of 

 Cuphea petiolata answer the description of Elachista ( ?) 

 metallifera Wlsm. described from a single specimen in which 

 the type of marking is evidently that of Psacaphora. The an- 

 tennal markings are by no means constant; sometimes the 

 last four or five segments are entirely silvery white ; some- 

 times there is a series of four or five whitish or grayish spots 

 separated by dark spots ; and sometimes the entire antennal 

 stalk is dark brown. The blue and purple iridescent dorsal 

 spot is in all, except one specimen, extended along the termen 

 to the apex ; in other respects the specimens agree minutely 

 with the description. It is remarkable for its minute size ; 

 expanse varying from 4.7 mm. to 6.5 mm. ; that of the type 

 was given as 5 mm. 



The larva makes several mines ; the earliest extremely short 

 and narrow and dif^cult to discern ; later it makes long con- 

 torted serpentine mines or blotches, eating out the whole of 

 the smaller leaves near the top of the plant. The larva often 

 crawls for a couple of inches with the greatest ease amongst 

 the extremely viscid hairs of the plant, in which ants and small 

 flies are often caught and held fast. The general color of the 

 larva is bright red, due to the obscuring of the yellowish 

 ground color by the confluence of the bright red markings 

 on either side of the mid-dorsal line. Cocoon spindle-shaped, 

 of dense straw-colored silk.
