1877.] 81 [Scudder. 



Gryllus pennsylvanica Burm. 2 J, 4 ?, found under boards 

 on the beach near Sanford, with the preceding, April 6; 3 ?, Ft. 

 Reed, April 20-22. One of the first mentioned females is much 

 larger than the rest, but appears to be the same species. Although 

 Saussure considers this a northern species, not occurring in the south, 

 these specimens agree well with a specimen from Maryland, com- 

 pared with Bnrmeister's type in the Halle Museum, and marked as 

 agreeing therewith; the same specimen was indicated by Mr. Uhler 

 as agreeing with specimens sent by him to Mr. Walker under this 

 name, and which probably served as the base of Walker's determina- 

 tion. This form at least of the species I have never seen north of 

 Maryland, and hence it appears to be a southern type. Saussure, 

 however, considers the forms described by me from New England 

 under the names of G. niger and 6?- neglectus, as identical with this. 



Nemobius ambitiosus nov. sp. Allied to N. carolinus Scudd., 

 but smaller and darker. Head not very convex, subappressed, the 

 top dingy fulvous with broad dusky or blackish longitudinal stripes ; 

 whole front piceous with a moderately narrow pallid transverse 

 stripe, widening slightly at the middle, and on the lower edge at 

 each lateral ocellus ; ocelli pale ; antennae fusco-luteous, much longer 

 than the body, the basal joint subcastaneous ; palpi, excepting the 

 pallid penultinate joint, black. Pronotum quadrate, its borders 

 straight with a rather strongly marked impressed line next the front 

 edge black, sometimes heavily and obscurely blotched with dark ful- 

 vous, covered sparsely, like the top of the head, with long curving 

 black bristles. Tegmina of d 1 black, more than half as long as the 

 abdomen, quadrate, more than half as long again as broad, as broad 

 at apex as at base, the tip broadly rounded and in the middle 

 subexcised, the entire margin and the edge between the dorsal and 

 lateral fields conspicuously bordered with pale yellow; tegmina of ? 

 with the lateral field black, the dorsal field testaceous blotched with 

 black, the veins dusky; less than half as long as abdomen, the inner 

 apical angle strongly and roundly excised. Legs black, blotched 

 heavily with luteo-testaceous, the hind tibial spines dull testaceous, 

 mostly black or dusky in the middle half. Ovipositor black, straight, 

 rather shorter than the hind femora ; cerci varying from dull testa- 

 ceous to castaneous. 



Length of body, 7.75 mm.; of antennae, 9 mm.; of pronotum, 1.6 

 mm.; breadth of pronotum, 2 mm.; length of tegmina, d", 3.5 mm.;
