turn, wholly black. Pronottiin lielicatelv and 

 briefly villous, about a third as broad again 

 as long, broadest in the middle b_v the gently 

 and regularly convex sides, the front and 

 hind margins truncate, with a median im- 

 pressed line failing to i-each the hind margin, 

 the lower margin of the lateral lobes a little 

 oblique and arcuate. Tegmina nearly cover- 

 ing (i?)> oi" somewhat shorter than (?) the 

 abdomen, black with a fulvous or flavous 

 humeral stripe especially distinct in the fe- 

 male, the apical area beyond the male tam- 

 bourine almost as long as its basal breadth, 

 the mediastinal vein with three branches ; 

 wings generally no longer than the tegmina, 

 but sometimes surpassing a little the abdo- 

 men. Legs black, the hind pair more or less 

 ferruginous especially in the female, the 

 hind femora stout, the hind tibiae with gen- 

 erally six spines on the inner side, the upper 

 inner calcar fully three fourths as long as the 

 intermediate calcar. Ovipositor about as 

 long as the hind femora.

In this species, the tegmina of the 

 male are almost as long as the abdomen 

 and the wings usually no longer; in the 

 female the tegmina are considerably 

 shorter than the abdomen and the wings 

 short so far as seen. It differs from the 

 other species by the distinct humeral 

 stripe of the tegmina, especially distinct 

 in the female, and in its stouter legs. It 

 further differs from G. inhxer in the 

 color of the tegmina, their lesser length 

 and shorter postspecular area, and in the 



narrower pronotum which is less villous : 

 and from G. peimsylvanicus (as occur- 

 ring on the Pacific slope) in size, in the 

 rather broader pronotum, which is less 

 villous, and its longer postspecular area 

 of the tegmina. 



Gryllus pennsylvanicus. 



Grylliis pennsylvankus Burm., Handb. 

 ent.,ii, 734 (1838). 



This is the most widely distributed 

 species of Gryllus in the United States 

 and appears to be the only Atlantic spe- 

 cies * found on the Pacific coast, where 

 it is much more common in the north 

 than in the south. Mr. Morse brought 

 home specimens from Mctoria, B. C, 

 Sept. 29 ; Tacoma, Sept. 25, and Tenino, 

 Wash., Sept. 24; Drain, Sept. 11, Divide 

 (Cottage Grove), Sept. 12, Corvallis, 

 Portland, Sept. 19, and Philomath, Or., 

 Sept. 15; and Lancaster, Cal., July 31. 

 I have besides seen specimens from Van- 

 couver Isl. (Edwards). British Columbia 

 (Crotch), Oregon (Edwards), and the 

 following localities in California — Mt. 

 Shasta, Soda Springs, San Francisco 

 (Edwards, Behrens), Santa Barbara 

 (Edwards), Colorado River, July 28 

 (\V. Somers), Mohave River (Palmer), 

 San Diego (Crotch, Webb). 



It is more uniformly black than any 

 of the other California species and dif- 

 fers from all of them in its shorter teg- 

 mina and alwa\s (so far as I have seen 

 them) short wings ; it is also peculiar 

 for the bent-arcuate rather than simply 



* Unless G. assriiii/is is found on the Atlantic coast.
