lar patch, which is edged narrowly with ochreous. Near the 

 inner angle are two dark brown oblique stripes. 



The typical genus Tortrix has the palpi much longer than 

 the head, with the fore wings about twice as long as broad, and 

 the costa arched abruptly at the base, while the outer edge is 

 truncate and sometimes hollowed out below the tip. T. geli- 

 dana Moschler is a common arctic form, and occurs commonly 

 in northern Labrador, and has been detected 

 on the Alpine summit of Mount Washington 

 by Mr. F. G. Sanborn. He has also detected 

 a new species which feeds on the cranberry, 

 for which we suggest the name Tortrix oxycoc- 

 cana. Its body is dark brown, with lighter 

 hairs on each side of the abdominal segments, 

 and fuscous at the tip. The fore wings are 

 of a peculiar glistening gray, mottled with red- 

 dish brown scales, especially towards the outer edge. There 

 are no well defined spots or bands. The hind wings and body, 

 and under surface of the wings are slate colored. The wings 

 expand -.64 inch. 



The Leptoris breviornatana of Clemens (Fig. 257 ; a, side 

 view of the head and labial palpi ; 6, fore wing ; c, hind wing), 

 which is referred to the genus Tortrix by Mr. C. T. Robinson, 

 has tawny yellow fore wings, with the veins brown. An oblique 



brown band arises on the basal 

 third of the costa, and runs to 

 the middle of the inner margin, 

 but does not reach it. On the 

 costa is a brown patch. It lives 

 in Virginia. Mr. Robinson also 

 informs me that in a forthcom- 

 ing paper on this family he re- 

 fers the Ptycholoma? semifus- 

 cana of Clemens (Fig. 258 ; o, head ; 6, fore wing ; c, hind 

 wing) to the present genus. "The fore wings are white along 

 the costa and hinder margin, marked with pale brown, ochreous 

 and tarnished silvery stripes and spots." It ranges from 

 Maine to Virginia. 



The genus Lozotcenia has palpi rather longer than the head.
