THE CANADIAN ENTOMOLOGIST. 325 



could not be certain of the determination without specimens for direct 

 comparison. 



197. Belostoma grisea Sdiy, correct Benacus gris^a%d,y. 



198. Zait/iafluminea Say, correct. Belostoma fluminea Say. 



199. Ranaira fusca, P. B. is R. americajia Montd. 



200. Notonecta irrorata Uhler, correct. 



201. Notonecta undulata Say, correct. 



202. Corisa, spp. My own material in this genus is still un worked 

 and I did not attempt to locate the Provancher species. 



204. Prionosoma villosum, n. sp, does not differ in any respect from 

 podopoides Uhler. 



204. Euschistus jugalis, n. sp. I could not find this in the collection 

 but from the description I am now strongly inclined to consider it the 

 form 0Ï servus with acute humeri although it might be conspersus Uhler. 



205. Platygaster pacificus, n. sp., correct. 



211. Cicada pruinosa Say, correct. 



212. Cicada septendecim Linn., correct. Tibicitia siptendecim Linn. 



213. Cicada canadensis^ n. sp. This is rimosa Say more strongly 

 marked with orange on the base of the elytra and wings than usual. I 

 have an exactly similar specimen which I cannot distinguish from rimosa. 

 It belongs to genus Okanagama Dist. and not to Tibicen, and is not 

 noveboracensis Emmons as I had conjectured. 



214. Cicada rimosa ^zy. The ordinary dark form of this species. 



217. Amphiscepa coqueberti Kirby is Otiocerus degeeri Kirby. 



218. Hysteropterum semivitreum, n. sp. This species was a surprise 

 to me and I had taken nothing at all allied to it for comparison. It seems 

 to belong to the Californian group of Issids and is very close to Dictyobia 

 per7tiuiata Uhler. It may be an accidental introduction from the west. 



219. Scolops sulcipes Say, correct. 



220. Helicoptera septentrionalis, n. sp. This is the Elidiptera I have 

 been determining as septentrionalis Prov. 



221. Helicoptera vesiiia, n. sp., \§ Elidiptera opaca'èid.y. 



222. Cixius stigmatus Say. This is the C. stigmatus of my table 

 published in Can. Ent., XXXVIII, p. 408, Dec, 1906. 



223. Oliariis quinquelitieatus Say, correct. 



223. Oliariis cinnamofneus^ n. sp., correct. 



224. Delphax unipunctata Prov. is Stenocranus dor salis Fitch. 



225. Delphax furcata Prov. This seems to be a good species of 

 Li bur nia.
