Class I, HEXAPODA. 



ORDER XI, ORTHOPTERA. 

 A NEW BACUNCULUS FROM INDIANA. 



By A. X. Caudell, 

 Washington, D. C. 



Bacunculus blatchleyi, new species. 



Body moderately slender, noticeably heavier than that of B. tenuescens. Head 

 smooth, subquadrate, in neither sex so strongly swollen anteriorly as in />'. tenuescens 

 and no more than twice as long as broad ; attached subhorizontally to the pronotum. 

 Pronotum about one fifth as long as the mesonotum, which is a little longer than the 

 metanotum, the moderately distinct intermediary segment included. Abdomen of the 

 male scarcely inflated apically, the seventh and eighth segments subequal in length, 

 each a little shorter than the ninth. Supra-anal plate small, triangular. Cerci of 

 female rounded and as long as the terminal segment of the abdomen, being about 

 seven or eight times as long as the basal width, straight and quite uniformly taper, 

 ing ; cerci of male cylindrical, scarcely at all tapering, curved downward and inwards 

 crossing each other as usual in both Diapheroviera and Bacunculus ; armed on the 

 inner side at the base with a distinct but blunt projection, or spine. Operculum of 

 male as in tenuescens but slightly more massive. Legs heavier and less attenuate than 

 in tenuescens, the middle femora of the male distinctly heavier and thicker than the 

 posterior ones and armed below near the apex with a stout, blunt curved spine ; mid- 

 dle femora of the female with a small spine near the apex below, otherwise the legs 

 of both sexes are unarmed. 



Color probably brown to green, or yellowish green. The speci- 

 mens before me were preserved in spirits and the colors are probably 

 considerably changed.

The females of this species are scarcely separable from those of 

 Diaplieromera veliei when unassociated with the opposite sex.
