eyes are brunneo-testaceous and aeneous in certain lights. Hind 

 tibia? grayish phimbeous, a little darker apically. Anterior and middle

 femora 10 mm. 



JIahiiat. — San Bernardino, Paragua}'. 



Type. — A single female taken b}" the writer in September. 



This insect approaches Bucej>halacris in some respects, but the pre- 

 vailing characters are those of Parnleuas. 



ORTHOSCAPHEUS, ne^jv genus. 



According to Giglio-Tos' table for the separation of the described 

 genera of South American Acridiiuse" the insect upon which the 

 present genus is based would run to Jodacrh.. The peculiar structure 

 of the ovipositor, as compared with that of J. fey'inig'mea.^ will, how- 

 ever, separate it from that genus, as will also several other characters. 

 Face, pronotum, and pleura strongly punctate. Female front sub- 

 \ertical, ver}' slightly advanced between the antenna? when viewed 

 lateralh^; frontal costa very broad an*d fairly prominent above the 

 ocellus, where if is without suk'ation and nearly impunctate, at and 

 below the ocellus a little narrower, sulcate and continuous to the 

 cl3'peus. Eyes fairly prominent, a little longer than the cheeks below 

 them, front edge nearly straight, the back side broadly- rounded; ver- 

 tex between the eyes about as broad as the basal antennal joint, the 

 fastigium broadly triangular, its front edges meeting in an obtuse 

 angle, narrowly and shallowly sulcate in the middle. Antenna^ presum- 

 abl}^ tiliform (the only specimen at hand is without them). Pronotum 

 profusely and strongly punctate, with the sides of anterior lobe parallel, 

 the posterior one expanding, the two lobes of about equal length, 

 the hind sulcus profound; front boarder broadly rounded the center 

 shallowl}'^ emarginate, hind border obtusangulate; median carina dis- 

 tinct in front and on the hind lobe; sides a little higher than long, the 

 edges nearly parallel, lower posterior angle square, the apex a little 

 rounded, the anterior angle obliquely truncate. Tegmina complete, 

 coriaceous, profusely and strongly veined, a little tapering, the apex 

 rounded, and the costal Held near the base rather strongly ampliate. 

 Hind femora moderately robust, the pinnae quite regular, their tips 

 not quite reaching the apex of the abdomen, the genicular lobes 

 rounded. Overpositor long and straight, the uppor valves without 

 teeth, of nearly equal width throughout, their apices bluntly mounded; 

 the lower ones smaller, shorter, and more slender, tapering and acumi- 

 nate, in a measure lying between the lower edges of the upper pair.
