compressed, often undulate, subobsolete on the process ; pos- 

 terior angles of the lateral lobes turned downward, the inferior 

 margin before the angle armed with a long cylindrical, acute 

 spine. Elytra oblong, acuminate toward the apices ; wings 

 perfectly explicate. Femora entire, distinctly lengthily at- 

 tenuate ; the anterior nearly as long as the middle femora ; 

 posterior tibiae shortened to about three-fourths the length of 

 the corresponding femora, lateral margins strongly dilated 

 toward the apices, first article of the posterior tarsi much 

 longer than the third, the lateral margins widely expanded, 

 the pulxnlli very small and subobtuse. 



This genus differs from Scelhvmena in the narrower vertex, 

 the raised position of the ocelli and insertion of the antennas, 

 in the lengthily attenuate legs, and in the turned down pos- 

 terior angles of the lateral lobes. The spiniform antero-dorsal 

 margin of pronotum is probably only of specific importance. 

 I would therefore include in this genus two species namely : 

 Amphibotettix longipes, the type described below, and Aphibo- 

 tettix abbotti Rehn.* 



Amphibotettix longipes sp. nov. Body slender, coarsely granulose, 

 fuscous, posterior femoral margins and ventral surface of body light yel- 

 low. Head not at all exserted ; vertex narrowed forward, considerably 

 narrower than one of the eyes ; eyes globose. Pronotum anteriorly 

 produced in a short, rather blunt spine, nearly vertically elevated, the 

 antero dorsal margin transversely somewhat tentate, posteriorly the 

 apical process profoundly prolonged backward, slightly more than twice 

 the length of the posterior femora, the apex acute ; dorsum between the 

 anterior margin and the shoulders on either side constricto-sulcate, be- 

 hind the shoulders shallowly bifossulate, with lightly tumose elevations 

 posteriorly; median carina very little compresso-elevated, undulate, in- 

 terrupted anteriorly and subobliterated backward on the apical process ; 

 humero-apical carinae dividing off rather narrow indistinct scapular areas ; 

 spine of posterior inferior margin of lobes straight and lengthily cylindri- 

 cal acute, almost transverse or leaning little forward. Elytra elongate, 

 the apex acuminate, surface coarsely granulose, below and toward the 

 apex finely reticulose ; wings extended backward nearly to the pronotal 

 apex. Anterior and middle femora extraordinarily slender, the anterior 

 strongly longer than the head ; posterior femora very slender, knee vt-ry 

 narrow, the antegenicular denticle absent, the genicular spine lightly pro- 

 duced ; the pulvilli of posterior tarsi equal in length, the third pulvillus
