88 THE CANADIAN NATURALIST. [Vol. viii. 



The dip on the south side of the beds, where it is more friable 

 than on the north, is to the N. E.<61°, while on the north side 

 it is to the S. W.<58°. At L'Isle du Lac Sale about three miles 

 nearer the shore, the Upper Laurentian rocks are seen to lie in a 

 synclinal striking N. 10° W. and dipping N. 80° E.<63° 26' on 

 the south-west side, and S. 80° W.<54° on the north-east side, 

 about four miles across the strike. They rest upon black dio- 

 rites and consist of twenty-nine feet of grey norites and thin red 

 gneisses overlaid by gneisses which are mostly coucealed by 

 vegetation. The bed of micaceous sandstone referred to is inter- 

 calated between an unknown thickness of white gneiss below 

 and about a thousand feet of reddish gneiss above. 



NEW AND INTERESTING INSECTS FROM THE 

 CARBONIFEROUS OF CAPE BRETON. 



By Samuel H. Scudder, 07 Cambridge, Mass. 



Dr. J. W. Dawson has placed in my hands a piece of carbo- 

 niferous shale from Cape Breton, containing remains of several 

 insects. The best preserved and most interesting is the abdo- 

 men of a larval Dr;igon-fly. Odonata, both mature and in their 

 earlier stages, have previously been found in the Jurassic beds of 

 Solenhofen ; wings and fragments of other parts have also been 

 found in the English Lias, and a specimen, which may be an 

 odouate larva, has been figured by Brodie from the Oxford Clay. 

 No true Odonata, however, have been discovered so low as the 

 carboniferous formation, unless the obscure fossil, thought by 

 Goldenberg to be possibly a Termes,* may properly be referred 

 to this group. 



In the last edition of Dr. Dawson's Acadian Geology, however, 

 I have described (p. 387) the wing of an insect, Haplophlebium 

 B'jrnesii, which certainly bears some striking resemblances to 

 the Odonata, and of which it is not impossible that the present 

 fossil may be the larva. 



* See Dunker and Meyer's Palasontographiea, iv, pi. vi, fig. 8. Sub- 

 sequently (Vorw. Faun. Saarb. 12) Goldenberg refers this definitely 

 to the Termitina, under the name Termes (Calotermes) Hageni.
