THE CANADIAN ENTOMOLOGIST. 



Primaries lanceolate, almost caudate; the costal vein runs near the 

 margin, which it reaches at about its middle. 'I'he subcostal sends two 

 branches to the costal margin from near the end of the discal cell, which 

 is closed rather acutely by the union of the subcostal and median veins. 

 The first of these branches is given oft" at the point where the subcostal 



'bends towards the median, and the second is given oft' almost from the 

 apex of the cell. The median vein is unusually large and distinct, and 

 from just behind the middle it sends a branch to the dorsal margin, from 

 the end of the cell it sends a furcate branch also to the dorsal margin ; 

 from the apex of the cell a discal branch, which is almost continuous 

 with the median, passes to apex, becoming trifurcate near the apex, one 



-of its branches going to the costal margin near the apex, one to the apex 

 and one to the dorsal margin near the apex. One or more tufts of raised 

 scales. 



Hind wings linear lanceolate ; costa somewhat naked from the base to 

 the basal fourth, and from thence excavated to the apex ; the costal vein 

 is close to the costa and enters it about the basal fourth ; the subcostal 

 proceeds to the apex ; behind the middle it sends two branches to the 

 -dorsal margin; the median is furcate behind the middle, close to the 

 margin, both branches entering the dorsal margin. Cell unclosed. 



P. Cknicnsella. N. sp. 



Palpi, face and eye-caps white ; tuft reddish orange ; antennae pale 

 reddish orange ; thorax white, with a reddish orange narrow stripe just 

 before the apex, and a spot of the same hue on each shoulder. Primaries 

 reddish orange, with two white basal streaks, one median, the other 

 dorsal, the latter continuous with the white of the thorax, and extending 

 to a small raised tuft of brown scales just before the middle of the dorsal 

 margin ; from the tuft the dorsal white streak is deflexed obliquely to 

 .about the middle of the wing, where it intersects at an acute angle the 

 median basal white streak ; at the apical third of the costa is a rather long 

 oblique costal white streak, which is produced along the extreme costa 

 towards but not to the base; apical portion of the wing dusted with dark 

 brown. Ciliae whitish, with an oblique, rather wide streak of reddish 

 orange, dusted with brown, resembling the "hook" of many species of 

 Gracillaria. 



AL ex. scarcely yl inch. Kentucky. Larva unknown. 

 I have named it in honor of Dr. Clemens, who may be called the 

 father of this branch of P^ntomology in this country.
