164 SECOND RErORT OF THE STATE ENTOMOLOGIST. 



ing. Here apiece of wheat of several acres in extent was attacked, and 

 considerably injured by it. 



Observed in other Northern and Eastern Localities. 



During the spring of 1883, the insect also occurred abundantly in at- 

 least one locality in Massachusetts, for according to Dr. George Dim- 

 mock, "on the 28th of March, the lowland between Belmont and 

 Cambridge was swarming with them" {Psyclic, Novem. -Decern., 1883, 

 iv, p. 119). 



An earlier observation of it in Massachusetts has been communicated 

 to me by Dr. Packard, in the following extract from liis diary: "June 17, 

 1871, at Salem, Mass., chinch-bugs with wing-covers extending over the 

 basal third of the abdomen, seen in copula, end-to-end." Dr. Packard 

 has also published the fact of liis liaving taken tlie insect " frequently 

 in Maine and even on the extreme summit of Mt. Washington in August " 

 {Guide fo tlie Slwhj of Insects, i86g, pp. 543-4). 



Mr. Henry L. Fernald, of Orono, Maine, wlio is making special study 

 of the Plemiptera, has given me the following memoranda of its occur- 

 rence at Orono, latitude 44° 40': "One example captured in 1879; one 

 on May 25, 1880; three on June 3, 1882. Since tliat time quite com- 

 mon in June ; taken in all cases Ijy sweeping over grass." 



Its occurrence in Canada, in 1866, in a few examples has already been 

 referred to (page 155). Ui)on inquiry, I learn that the locality of their 

 collection by Mr. J. Pettit, was at Grimsby. 



For a still more northern locality of the insect we are indebted to the 

 recent collections of Mr. \W. H. Harrington, of Ottawa, Ont., who, at 

 the annual meeting of the Entomological Society of Ontario, at London, 

 in October of 1884, exhibited specimens of the chinch-bug which he had 

 found abundant at Sydney, Cape Breton (N. latitude 46° 18') during a 

 visit there in September {Canndian Entnmolofjist for November, 1884 

 xvi, p. 218).
