PSYCHE. 



[May 1900. 



large, but slightly tumid. Eyes small but 

 prominent. Antennae, head, pronotum and 

 femora testaceous. Maxillary palpi light 

 yellow throughout or with the apical third of 

 terminal joint infuscated. Tegmina of $ 

 reaching tip of abdomen, testaceous with a 

 narrow piceous bar on upper third of lateral 

 field and with basal third of dorsal field usu- 

 ally more or less piceous. Tegmina of ? 

 covering one half or more of abdomen, the 

 dorsal field usually heavily shaded with pic- 

 eous; wings absent in both sexes. Upper 

 surface of abdomen piceous, lower surface 

 testaceous or luteous. Ovipositor a third or 

 more shorter than hind femora, distinctly 

 arcuate, the apical blade not enlarged at the 

 base, armed above with very small and rather 

 dull teeth which are irregulai'ly distant one 

 from another. Length of body, 7.5 mm.; of 

 hind femora, 6.3 mm.; of ovipositor, 3.5 

 mm. ; of tegmina, $ , 5 mm., ? , 4 mm. 



This is the " iV. exigutts Scudder" 

 of my paper on the " Gryllidae of Indi- 

 ana" loc- cit. It appears, however, 

 that Scudder had not described a species 

 as exiguus but had merely mentioned a 

 form of N. fasciatjis under the name. 

 Beutenmuller afterward * desciibed A'. 

 affitzis from New York, which he .stated 

 was the insect mentioned by me, but 

 which, according to Scudder, f is N. 

 carolinus.

Exigims is longer and proportion- 

 ately more slender than carol/iias, 

 though the tegmina of the male are 

 broader. The pronotum and femora 

 are not mottled or marked with fuscous 

 as in that species. The serrations of 

 ovipositor of carolinus are smaller, 

 sharper and more evenly separated than 

 in exiguus. The latter species occurs 

 in all parts of the State and is fully one- 

 half as cotnmon as N. fasciatus vitta- 

 tus. Its liabits, time of appearance and 

 local habitat are also essentially the same. 

 However, the smaller size, short ovi- 

 positor, yellowish maxiliarv palpi, and 

 otlier diflerences in color, reathly distin- 

 guish it from vittatits. 



6. N. cubensis ? Saussure. 



Two (J 's, distinct from those of any 

 of the above species, were taken Octo- 

 ber 9th, 1893, from the sandy bed of the 

 old canal north of Terre Haute, Indi- 

 ana. Tliey were sent to Mr. Scudder 

 who reports them probably tlie short- 

 winged form of N. cubeiisis. In life 

 they were shining black with a bright 

 yellow line separating the dorsal and 

 lateral fields of the tegmina. No cor- 

 responding females have as yet been 

 secured from Indiana, but Scudder le- 

 cords two as having been taken in Illi- 

 nois.
