HANCOCK 1 1 7 



Several varieties of this species exist presenting slight 

 differences in the vertex and middle femora together with 

 abbreviation of wings and pronotal ])rocess. For the form 

 having the jjronotal process and wings abbreviated the tri- 

 nominal Paratettix iiicxicanus abortus may be used. Eight 

 specimens of this form are in the author's collection. 



PARATETTIX TUBEKCULATUS, SP. N. 



Plate VIII., Fig. 3. 



Allied to Paratettix incxicamis, which it resembles nearly 

 in proportion of body, but distinguished principally by the 

 tuberculate character of the posterior femora. The anterior 

 femora little compressed, the inferior margin scarcely lobate 

 a little beyond the middle; middle femoral margins distinctly 

 sinuate, su]:)erior margin towards the apex broken into small 

 undulations, below strongly sinuate-Iobate, near the middle 

 formed into distinct lobe with substraight or slightly curved 

 border; posterior femora moderately stout, the apical half of 

 superior marginal carina serrate, the femoral lobe formed into 

 a distinct tooth projecting subinwards, two or three oblic[ue 

 ridges of external pagina a little beyond the middle tumes- 

 cent, the straight carina below with a prominent tubercle, and 

 a second appears midway betvyeen it and the apex; as viewed 

 from above both tubercles projecting plainly from the lateral 

 surface; at a corresponding distance there is a trace of a 

 tubercle at the anterior fourth on the straight carina; the pos- 

 terior tarsal characters are the same as in iiicxicanus. 



Length of body, 5, 12.5 mm.; pronot., 9.2 mm.; post, 

 fem., 5.6 mm. 



Locality, Vera Cruz, Mexico (Barrett) Hancock. 



PARATETTIX MORSEI EXTENSUS, MORSE. 



Plate VIII., Figs. 8 and 9, and face Fig. 16. 



Body moderately robust, little rugose; color variable, 

 grayish or light spotted with fuscous behind the shoulders with 

 two large dark impressed spots, and four or five spots along
