PSYCHE. 



[October 1S94.. 



born, April and Sept., and from 

 Wellesley in April, May, June, July, 

 Sept., and Oct. I have but a few 

 nymphs which were taken in July, 

 Aug., and Sept. 



It seems to be less active and alert 

 than its congener granulatus. My 

 specimens were secured by sweeping.

Tettix granulatus H'why. Morse, 54, 106. 



Bolivar states that this species is very 

 similar to T. bifunctatus'L. of Europe. 

 From a comparison with specimens of 

 the latter species (determined by 

 Brunner) in Mr. Scudder's collection 

 this is a serious error. T. bipunctatus 

 is closely allied to our Nomotcttix 

 cristatiis. probably belonging to the 

 same genus. Bolivar's descriptions, 

 fio-ui-e and localities lead me to think 

 that possibly he has described this 

 species as new under the name of 

 T. brimneri and applied grajiidatiis 

 to T. acadicus Scudd. 



Descyiption, etc.— Anterior border of vertex 

 considerably advanced in front of eyes, 

 angulate, the apex very slightly rounded, or 

 rarely with the mid-carina projecting a trifle. 

 In profile the face is quite retreating, the 

 vertex considerably advanced, sinuate oppo- 

 site the eyes, and moderately protuberant 

 opposite antennae. The eyes are the least 

 prominent in this of any of our species, and 



the body more slender. It is liable to be 

 mistaken for T. ornatns only, but the out- 

 lines of profile and vertex, considered 

 together, need leave no doubt of the species. 

 It bears considerable resemblance to T. 

 subulatus of Europe.. 



Measurements are as follows : —

In one <? the pronotum is but 1.2 mm. 

 longer than the hind femora and the wings 

 are .3 mm. short of end of pronotum. This 

 is extremely small but other examples from 

 the same locality grade up to the usual size. 



Habtis, etc.— This is one of the 

 most common and widely spread species 

 of the group, sometimes locally plenti- 

 ful. It is found over probably the 

 whole of New England, and far west 

 and north. While most plentiful in 

 spring and fall, adults can probably be 

 found every month in the season. I 

 have speciinens from New England as 

 follows : — 



Fryeburg, Me., Aug. 20, numerous.
