1915] Parshley — Hemiptera-Heteroptera of Maine. 23 



recent paper,' Van Duzee discusses several points belonging to 

 the latter class. 



P. 140. Arctocorixa should read Arctocorisa. All the Corixids mentioned be- 

 long to this genus. 

 A. harrisii is a dimorphic cf form of interrupta. 

 P. 141. Horcias limhafeUus is a form of dislocatus goniphorus Say. 

 P. 142. P. dislocatus with its varieties belongs to the genus Horcias. 

 Cyrtorrhinus should be deleted. 

 C. marginatus doubtless =Orthotylus congrex. 

 Orthotylus is correct. 

 H. ctVn'=uhleri Giard. 

 iS/j/?/(ra.wH(rt = Strongylocoris Blanchard. 

 7rfo/oro/-;> = Dicyphus Fieber. 

 Megalocoleus should be deleted. 

 M. coagulatus belongs to the genus Orthotylus. 

 P. 143. Under Clinocoris insert Cimex Auct., Linnaeus.' 



Acanfhia Auct. 

 After Nepa apiculata Harr. insert Uhl. 

 P. 144. The record of Apiomerus ventralis has been questioned by several corres- 

 pondents. The data were taken from a specimen in the Boston Society 

 collection, determined by Van Duzee, as I am informed by Mr. C. W. 

 Johnson. It was collected by C. A. Frost, who has taken another 

 specimen at Framingham, Mass. 

 Zelus exsanguis and Z. luridus are considered distinct by Van Duzee. 



Both forms occur in Maine. 

 Limnoporus is considered a subgenus of Gerris by Torre Bueno, our 

 authority on aquatic Hemiptera. 

 P. 145. Tingis should read Melanorhopala Stal. 

 P. 146. Say's Lygceus scolopox is unknown. Uhler's record of Orsilhis scolopax 



doubtless refers to Nysius longiceps. 

 P. 147. Before Aneurus insert F.^mily DYSODIID.E. 



C. typhcvus should read C. distinctus Dallas. As noted by Barber,^ the 

 description of Dallas makes it clear that the northern form is distinctus. 

 P. 149. A. sereiventris should read A. serieventris. 



Homaemus should read Homaemus. 

 The following records should be added to the list: 



Horcias dislocatus scutellatus V. D. Portland. 



Lygus tenellus V. D. Me. 



Melanorhopala clavata. 15 July. Pownal. 



Gsocoris uliginosus Say. 5 July-13 Sept. Pownal, Westbrook.
