PSYCHE. 



c? > 15-17; 9> 20-24 nim. The teg- 

 mina fall distinctly short of the end of 

 the abdomen in both sexes, reaching on 

 the hind femur a point from one-half to 

 two-thirds the length of the latter 'from 

 its base. 



This is one of our rarer locusts and 

 with its delicately contrasted tints of 

 green and purple is one of our daintiest 

 and most attractively colored species. I 

 took one male, all that I could find, at 

 Wellesley, Mass., in August, 1891, in 

 the early days of my collecting. This 

 specimen was referred to Mr. Scudder 

 who determined it provisionally as H. 

 viridis under which name it was recorded 

 (Psyche VI, p. 262) and referred to in 

 my List (Psyche VII, pp. 103, 106). 

 In the succeeding July I found a female. 

 The next year, owing to absence at the 

 proper time, none were taken. In 1894 

 and '5 I took several. In 1896 my 

 pupils and I secured a number from va- 

 rious points near the first locality. All 

 were captured by sweeping vigorously 

 the short, tufted growth of bunch-grass 

 {Andropogon scoparins) which with other 

 wild grasses and running-blackberry 

 vines sparsely clothe the thin soil of the 

 gravel-plain formation of Wellesley. It 

 has since been found by Mr. F. H. 

 Sprague, from whom I have received 

 specimens, in a similar station at Walpole, 

 Mass. (Psyche, VII, 439). In New 

 Jersey it is said by Uhler to be not un- 

 common in the cranberry fields of At- 

 lantic Co. While apparently very local 

 it probably inhabits many parts of the 

 three southern New England States. 



The season during which it may be 

 found seems to be relatively short ; the 

 Wellesley specimens were all taken be- 

 tween July 10 and Aug. 8, nymphs being 

 secured on the first date and search in 

 September proving unsuccessful. Mr. 

 Sprague's specimens were taken on 

 Aug. 30. but he was unable to find a 

 male.

This singular and interesting locust is 

 not uncommon on the mountains of New 

 England in the latter part of summer. 

 The specimens in my collection were 

 taken between Aug. 14 and Sept. 6 on
