MEXICAN ORTHOPTERA. 89 



This name was doubtfully placed under obscurellm Redtenhacher 

 by Saussure, but why is not plain, as my Mexican specimen perfectly 

 agrees with the description of Scudder's hebes. 



Xiphidiuin ictiiin Scuddei'. 



1875, Xiphidium ictum Scudder, Proc. Bost. Soc. Nat. Hist., xvii, p. 461. 



One specimen ; male, Cuernavaca, Morelos, vi. 



This specimen agrees very well with Scudder's description, except 

 the frontal constriction of the vertex is more decided than in the 

 specimens he described. 



Capnobotes iiiiperfectus n. sp. 



Types: three males, Rio Cocula, Guerrero, xii, 1898. 



This species differs from all the known representatives of the 

 genus in the abbreviated elytra, and in the processes of the meso 

 and metasternum being decidedly spinous. The nearest ally that I 

 can see is fuliginosus Thomas, but it differs decidedly from that, 

 probably representing a new subgenus. 



Size niediura ; vertex full and swollen ; eyes round and somewhat prominent; 

 frontal process moderately produced, sulcate ; antennae over twice as long as the 

 body. Pronotum abruptly elevated posteriorly, the anterior border slightly so, 

 the outline viewed laterally being rather saddle shaped : anterior and posterior 

 margins almost straight, slightly indented centrally; lateral lobes fairly deep 

 anteriorly, deepest on the line of the anterior coxse, thence broadly trimmed to 

 the posterior margin ; lateral and median carinas faintly marked posteriorly. 

 Elytra reaching only to the fifth abdominal segment, broadly rounded, lateral 

 portion sharply deflected. Processes of the meso and metasternum nearly as com- 

 pletely spinous as those of the prosternum. Anterior femora inferiorly with two 

 rows of rather obsolete spines; tibite with six large spines. Median femora the 

 same; tibiae with four rows of spines, the superior ones imperfect and irregular. 

 Posterior femora very smooth, two rows of rather obsolete spines inferiorly; 

 tibiae al)ove smooth anteriorly, from the median section commence- two rows of 

 spines which increase in numbers to the extremity, above with two rows of spines 

 complete, except a small section anteriorly. Male appendages somewhat similar 

 to faliginosus, but the superanal plate is by no means so produced, the cerci being 

 ;fully exposed, the latter much the same as in the above, but the subterminal spine 

 very much hooked. Subgenital plate as in fuliginosus, oue specimen showing the 

 cylindrical appendages well developed, while they are absent in another. 



Head and pronotum dull lemon-yellow, washed above with wood-brt)wn 

 (faintly iu one individual), lightest below. Antennae wood-brown. A dull, dark 

 brownish line is continued back of the eye on the superior portion of the lateral 

 lobes of the pronotum. Central portion of the pronotum marked with four 

 rather regular blotches of blackish ; the sloping lateral margin with a broad band 

 of white. Elytra green, external border lightest, darkest centrally. Abdomen 

 rich wood-brown, scrumbled with dull ochre, beneath pale yellowish. Femora 

 pale yellowish green, the posterior part infuscated in several specimens; ex-
