No. 34.] HEMIPTERA OF CONNECTICUT: CERCOPIDAE. 237 



custom adopted by Dr. Ball and other workers on this family, I 

 have considered it as a variety form of obtusa and appended the 

 original description hereto. 



"Testaceous ; scutel rufous ; elytra with a polished callous-like 

 black dot near the apex. Length 0.20 inches." 



Distribution: It has been reported from New York (Fitch), 

 and from West Virginia, District of Columbia and New Jersey 

 (Ball). 



Rainbow, 27 Sept., 1922 (P. G.). 



Under delicata Uhler, I have already stated, in agreement with 

 Van Duzee (1912), that lineatocollis Stal is distinctly not a sub- 

 species of obtusa (Say) as thought by Dr. Ball, but rather appears 

 to me a probable synonym of delicata. A specimen determined by 

 him as obtusa susb. lineatocollis may be placed readily as a dark 

 form of obtusa var. obtusa. 



Mr. Van Duzee (1912) states that var. achatina, as included by 

 Dr. Ball under obtusa subsp. obtusa, is not the true achatina 

 Germar; and he proposes the variety name tristis for this form, 

 together with proteus Provancher (1889). I cannot follow 

 Van Duzee in this instance, having examined a specimen deter- 

 mined by Dr. Ball as the above form, which answers the descrip- 

 tion of achatina Germar in every particular. The form achatina 

 appears to me, however, as quite distinct from obtusa var. obtusa 

 and is another variety of obtusa, as placed by Van Duzee. 



Osborni Gillette and Baker appears to be a distinct species as 

 listed in Van Duzee's "Check List — 191 6" rather than a sub- 

 species of obtusa, as placed by Dr. Ball. In this consideration of 

 osborni as a distinct species, I have also accepted Van Duzee's 

 placing of pint Fitch as a variety of proteus supplanting the 

 variety name nigra, as proposed by Dr. Ball. 



With these alterations, C. obtusa (Say) is presented above with 

 the varieties obtusa Ball, achatina Germar, and testae ea Fitch.
