THE PROVANCHER COLLECTION OF HEMIPTERA 127 
189. Salda ligata Say, probably correct. 
190. Salda obscura Prov. is Zttoralis Linn. 
190. Salda major Prov. is deplanata Uhler, which name 
it must supercede as it has priority by one year. 
191. Sal/da littoralis LAnn. is 2nterstitialis Say. 
191. Salda Zlugubris Say. Apparently 7epleta Uhler, 
but I could not be certain without specimens for compari- 
son. 
192. Sctodopterus bouchervillet Prov. is coriacea Uhler, 
which name it must supercede having priority. 
193. Zrmnobates lineata Say, correct. 
195. Gerris rufoscutellatus Latr., correct. 
195. Gerris remigis Say, correct. 
195. Gerris marginatus Say, correct. 
196. Gerris canaliculatus Say. This may be #venoi 
Kirk. It is smaller than warginatus and stouter than 
canaliculatus usually is; but I could not be certain of the 
determination without specimens for direct comparison. 
197. Belostoma grisea Say, correct. PBenacus grisea 
Say. 
198. Zattha fluminea Say, correct. Belostoma fluminea 
Say. 
199. Aanatra fusca P. B. is X. americana Montd. 
200. Votonecta 1rrorata Uhler, correct. 
201. Votonecta undulata Say, correct. 
202. Corisa, sp. My own material in this genus is still 
unworked and I did not attempt to locate the Provancher 
species. 
204. Prionosoma villosum, n. sp., does not differ in any 
respect from pfodopoides Uhler. 
204. Euschistus jugalris, n. sp. I could not find this in 
the collection, but from the description I am now strongly 
inclined to consider it the form of servus with acute 
humert, although it might be conspersus Uhler.
