verse dark brown arc next the posterior border ; cuneus long and wide, 

 the incised base fuscous and the inner margin brown ; membrane pale

 the principal areole, a spot at its tip and the base next the cuneus all more 

 or less fuscous. Ventor pale greenish. 



Length of body, ^ 5 millims.; to tip of wing covers 7 miUims. ; width 

 of pronotum, 2 millims. ^ . Length of body, 4 milUms. ; to tip of wing 

 covers 5^ millims. ; width of pronotum, i^ miUims. 



This has proved to be a very common insect in various localities. 

 * Mr. Cassino collected numerous specimens around Peabody, Mass. 

 Mr. Bolter sent to me a pair from Illinois and Missouri, and I have taken 

 it from Alders, Maples and many other kinds of small trees and shrubs on 

 Cape Ann, Mass., also near the base of the White Mountains in New 

 Hampshire, and near Quebec, Canada. 



Mr. Forbes has also forwarded to me specimens from near Normal, 

 111. It resembles Lygus invitus, Say., and presents several of the color 

 varieties common to that species, but it is a much larger insect, of a longer 

 figure, and has a more flattened upper surface. 



OCCURRENCE OF THE CHINCH-BUG (BLISSUS LEUCOP- 

 TERUS, Say) AT BUFFALO, N. Y. 



BY E. P. VAN DUZEE. 



This pernicious'insect has been very abundant here for many years. 

 As early as 1874 I found it in considerable numbers among moss on dry, 

 grassy hill-sides at Lancaster, N. Y. This season (1886) it was remark- 

 ably abundant in a dry upland hay field near the same locality. I have 

 also taken it at Ridgeway, Ont. Ordinarily the short winged form 

 predominates, but in hot, dry summers, such as those of 1881 and 1886, 

 they mostly acquire fully developed membranes. I find on comparison 

 with a lot of perhaps one hundred fully developed examples from Kansas, 

 that ours are quite uniformly larger and more robust, with longer hairs on 

 the pronotum.
