in the female, rather long oval, much longer than the infraocular portion 

 of the genae. Pronotum long and slender, the dorsum fully half again as 

 long as broad; the prozona little longer, sometimes half again as long as 

 the metazona, with less distinction in surface and sculpture between them 

 than common, alike broadly tectiform, the median carina slight but alike 

 or nearly alike in both, the descending lateral lobes separated by no angle 

 or ruga; posterior margin very obtusely angulate, the angle rounded, 

 the border delicately margined. Prosternal spine rather long, bluntly 

 conical; mesostethia and metastethia together much longer than broad; 

 interspace between mesosternal lobes generally twice as long as broad in 

 the male, almost equally narrow or subquadrate in the female, the meta- 

 sternal lobes subattingent in both sexes. Tegmina and wings always 

 present, generally fully developed or abbreviate, but sometimes lobate. 

 Fore and middle femora of male tumid; hind femora long and slender, 

 somewhat compressed, generally surpassing the abdomen, the superior 

 carina slight, unarmed ; hind tibia feebly amplicate apically, with spines 

 of similar length on the two sides; first joint of hind tarsi scarcely longer 

 than the third, the second small, with a large inferior apical lobe; aro- 

 lium rather large, nearly twice as long as broad. Subgenital plate of 

 male furnished with a prominent, subapical, more or less conical tubercle, 

 the lateral margins of the plate suddenly ampliate at the base; furcula 

 always distinctly present as a pair of projecting lobes; last abdominal 

 segment of female not abbreviate, the ovipositor normally exserted. 



This genus is closely related to Hypochlora and Campy la cant ha, but 

 is separated from them by the basal ampliation of the margins of the 

 subgenital plate of the male. The genus is still more closely allied to 

 JEoloplus, from which it is separable by the form of the pronotum and 

 the slenderness of the body. — 1. c. Scudder. 



Key to Species of Hesperotettix. 



A 1 . Metazona of pronotum distinctly punctate on dorsum but not rugulose; prozona 

 smooth. 

 b 1 . Dorsum of pronotum nearly plane ; transverse sulci of pronotum distinctly 



marked in black viridis. 



b 2 . Dorsum of pronotum tectiform ; the transverse sulci not marked in black or in 



strong contrasting colors. . ., pratensis. 



A". Prozona and metazona, both on dorsum and lateral lobes equally and distinctly rugu- 

 lose speciosus. 



Hesperotettix vh'idis Thos. 



The infraocular bar and the infra-antennal band vary from olivaceous 

 to black, the infra-antennal band being absent in some of the specimens, 

 while in others it forms a wide band reaching from the eye down to the 

 clypeal suture. Longitudinal stripe of vertex olivaceous to black; sides 

 of head behind the eyes streaked longitudinally with darker colors, 

 sometimes becoming a broad olivaceous to black postocular band. 

 Mediodorsal stripe white to ochraceous, or sometimes the stripe is 

 ochraceous on the prozona and white or greenish white on the metazona. 

 Lateral lobes of prozona variegated by an irregular assortment of brief 

 longitudinal dark green, rarely black, bars. The greenish tinge on the
