A TROPICAL TYPE OF ACRIDIAN NEW TO THE 

 UNITED STATES. 



By Samuel H. Scudder. 



Professor T. D. A. Cockerell sent me last May from New Mexico a 

 pair of Acridians of a type wholly new to me, apparently belonging to 

 a new genus, and even forming a group apart, intermediate between 

 the tropical American Aleuas and Vilernre in that the fastigium of the 

 vertex is deeply channeled and the hind femora are slender with the 

 superior carina smooth ; unlike the species in both these groups the 

 tegmina are abbreviated and lateral. Unfortunately I have few species 

 of either of these groups with which to compare it and must depend 

 largely upon the tables and diagnoses of Stal and Brunner. It bears 

 a superficial resemblance to a Pyrgomorphid, but is a true Acridian. 

 The genus and species are described below. 



Clematodes (/cx-^;/,a, sloo'^), gen. nov. 



Body elongate. Head porrect ; face oblique, bent inward, the deeply channeled 

 fastigium of the vertex protruding beyond the eye by more than half ( J* ) or nearly the 

 whole of ( J ) the width of the eye, paraboloid in front, with large triangular, some- 

 what elongate lateral foveolse, facing upward and outward, their plane at right angles 

 with the tempora, the inner margin arcuate; frontal costa narrow, subequal, deeply 

 sulcate with carinate margins, percurrent, widening a little below ; lateral carinse of 

 the face prominent, scarcely divergent below ; eyes rather large, prominent, espe- 

 cially in the male, ovate, oblique or obliquely subvertical ; antennae stout and thick, 

 not so long as head and pronotum together, tapering (especially in female) from base 

 to a rather blunt apex, triquetral nearly throughout, punctate. Pronotum compressed- 

 cylindrical, feebly enlarging from in front backward, multicarinate, the front margin 

 slightly raised to embrace the head, the hind margin distinctly and angularly eniar- 

 ginate, the lateral lobes considerably longer than deep, with nearly straight and 

 nearly horizontal lower margin, and roundly continuous with the disk ; prozona 

 nearly ( 9 ) or quite { $ ) twice as long as metazona, the sulci distinct and percur- 

 rent, the anterior sulcus crossing only the disk. Prosternal spine moderate, tri-
