THE CANADIAN ENTOMOLOGIST. 157 



LISr OF HEMIPTERA TAKEN BY W. J. PALMER, ABOUT 



QUINZE LAKE, P. QUE., IN 1907. 



BY E. P. VAN DUZEE, BUFFALO, N. Y. 



(Continued from page 116.) 



Tettiooniid^. 



Oncoinetopia cosia/is, Fabr. — Apparently common. 



Tetti^oiiia got/iica, Sign. — Taken at Temagami. 



DiedrocepJiala coccinea, Forst. — A most beautifal species, which 

 seems to liave been abundant at all places where Mr. Palmer collected. 



DrcpcuIacepJiala niollipes, Say. — Taken at Quinze Lake only. 



Dneculacephala Jiovceboracensis, Fitch. — Quinze Lake. Apparently 

 common. 



Gypona Quebecefisis, Prov.— Common at all stations. 



Jassid^. 



Platymetopitis acntiis^ Say. — Taken in numbers at Temiskamingue. 



Platytnetopius iatus, Baker. — With the last, and at Bear Island in 

 Lake Temagami and about Quinze Lake. This species, which I have 

 taken in New York, Ohio, Colorado and Utah, has been a difficult form 

 to i)lace. The larger and paler specimens from Utah have been deter- 

 mined for me as Baker's Iatus, and in all essential characters they seem to 

 agree fairly well with the description of that species. From these paler 

 forms they run by almost insensible gradations in form and colour toward 

 the smaller and darker aciitus. In all, however, the vertex is longer, the 

 oblique veins of the costa are more regularly placed, and the face is either 

 entirely pale or but slightly infuscated exteriorly, with the basal angular 

 pale line never entirely obsolete. I believe these should be separated 

 from aciitus, but whether they are the true Iatus of Baker is perhaps 

 questionable. This species, acutus, Say, and frontalis, Van D., are 

 common and widely distributed. The closely-allied cupi'escens, Osborn, 

 I have taken at Phoenicia, Colden and Gowanda, N. Y., always on springy 

 spots among the hills. 



Platymetopius obscurtcs, Osborn. — Barrier Lake. Two examples. This 

 is an interesting addition to the Canadian fauna. It was described by 

 Prof. Osborn from material taken in New York, Pennsylvania and Ohio. 

 It has the infuscated face found \x\ fuscifrons, but most closely resembles 

 acutus, than which it is smaller, stouter and has a shorter vertex. Of this 

 cosmopolitan genus fifteen species have thus far been recorded from 



May, 1908
