Gryllus Jit mu$ sp. no\'. — Large and stout, 

 with piceous bodj. Head large, tumid, uitli 

 prominent vertex, scarcely broader than the 

 pronotum. wholly- black. Pronotum stout, 

 black, most delicately margined anteriorly 

 with ferruginous, broadest in advance of the 

 middle, the sides being slightly and not quite 

 uniformly convex, half as broad again as 

 long, the front margin with scarcely per- 

 ceptible concavity, the hind margin slightly 

 but distinctly and broadly convex, with a 

 median impressed line scarcely or not visible 

 on posterior third, the lower margin of the 

 lateral lobes oblique and nearly straight. 

 Tegmina nearly or quite covering the ab- 

 domen, testaceous more or less infuscated, 

 often in the female leaving a clear testaceous 

 humeral stripe, the mediastinal vein with 

 three or four branches; wings generally no 

 longer than the body, but sometimes caudate 

 in the female. Legs ferruginous or testaceo- 

 ferruginous, often more or less infuscated, the 

 hind femora stout, the hind tibiae with gener- 

 ally six or seven rather long spines on the 

 outer side, the upper inner calcar very long 

 and almost as long as the intermediate calcar. 

 Ovipositor fully a third longer than the hind 

 femora.

 same, J' ? , 7.5 mm. ; length of tegmina, $ $ ,

 Rufus Hayvvard); Smithville, N. C, Nov. 

 22 ; Dingo Bluff, N. C, Nov. 15 (Parker 

 and Maynard); Georgia (Oemler, Ger- 

 hardt); Sandford, Fla. (G. B. Frazer); 

 Key West (Morrison) . I have also speci- 

 mens from Texas. 



This is the largest United States spe- 

 cies known to me. About a third of the 

 specimens seen are macropterous. 



Grylliis riibeiis sp. nov. — Rather large and 

 somewhat slender, the body piceous with 

 rufous and rufo-testaceous markings. Head 

 large, full, the vertex rather prominent, slight- 

 ly wider than the pronotum, the whole head 

 piceous. Pronotum about half as broad again 

 as long, subequal with scarcely convex sides, 

 feebly villous, piceous, the front and hind 

 borders very narrowly margined with rufo- 

 testaceous, the lateral lobes broadly striped 

 above (at place of lateral carinae) and down 

 the front with rufo-testaceous, the front mar- 

 gin of disk very faintly angulato-emarginate, 

 the hind margin very faintly bisinuate, the 

 lower margin of lateral lobes gently and ob- 

 liquely convex and broadly and feebly mnrgin- 

 ate. Tegmina covering the abdomen, tes- 

 taceous, faintly infumated, the mediastinal 

 vein with three branches; wings in only speci- 

 men seen not surpassing the tegmina. Legs 

 rufous slightly tinged with testaceous and 

 more or less infuscated, the hind femora 

 moderately stout, the hind tibiae with six 

 rather long spines on the inner, seven on the 

 outer margin, the upper inner calcar nearly 

 as long as the intermediate calcar. Ovipositor 

 about a fourth longer than hind femora. 



Lengtli of body, 20 mm. ; pronotum, 3.75 

 mm.; breadth of same, 6 mm.; length of 

 tegmina, 12 mm. ; hind femora, 13 mm. ; ovi- 

 positor, 16 mm.

A word may be added concerning 

 wing-length. Of the ten species of 

 Gryllus recognized in this and my 

 complementary paper, all but two appear 

 in both the forms, macropterous and 

 brachypterous ; and of these two one, 

 G. ruhciis, is known only by a single 

 specimen, and the other, G. dcmiestkus, 

 is known to occur in both forms in 

 Europe, though here I have seen only
