THE CANADIAN ENTOMOLOGIST. 131 



Variety B. Trunk sea-green, above black with two sea-green longi- 

 tudinal stripes ; abdomen black, sea-green at the 

 base, inscribed with black ; legs black above, under- 

 neath sea-green or white ; the stigma of the wings is 

 blackish with a transparent margin. 



C. Trunk black and white with two dorsal white longitudinal 

 stripes ; legs black ; stigma of the wings black ; 

 abdomen mutilated. 



Both taken in Lat. 65 . 



[Hagen (Synopsis of Neuroptera of N. A., p. 98) says that this is 

 " perhaps another species which is inextricable." ] 



FAMILY PERLID.E. 



348. Perla iucaudata Linn. — Length of body about 7}^ lines. 

 Several specimens taken in Lat. 68°. 



[253.] Body black, hairy. Antennae, tibiae, tarsi, caudal setae, and 

 wings dull testaceous ; the vertex consists of a yellowish membranous 

 spot ; the joints of the caudal antenniform organs are dark at the tip. 



The larva is white underneath, fusco-cinereous above ; head and 

 thorax spotted with white, with a pale longitudinal line. More than one 

 species seems to have passed under the name of Phryganea bicaudata. I 

 will not affirm that the present species is not distinct : but as the speci- 

 mens were not perfect, I thought it best to consider them as belonging to 

 that type. 



[Synonymous with P. frontalis Newman. Taken at St. Martin's 

 Falls, Albany River, Hudson's Bay ; at Trenton Falls, N. Y., and in 

 Ohio.] 



IV.— TRICHOPTERA. 



FAMILY PHRYGANIDAE. 



349. Limnephilus nebulosus Kirby. — Length of body 7 lines. A 

 single specimen taken in Lat. 65 . 



Body black, hairy with whitish hairs. Antennae are mutilated in the 

 specimen, but the base is black ; scutellum testaceous ; upper wings 

 testaceous, spotted and dotted with white except the costal area, which is 

 without any of that colour ; under wings white with testaceous nervures \ 

 legs testaceous.
