NO. 1124. EEVISION OF THE MELANOPLI SCUDDEli. 31 



zona, divided in the middle by a feeble, straight, transverse sulcus, 

 followed at scarcely less than halfway to the inetazona by a similar 

 sulcus. 1'rosternal spine erect, rather long, pyramidal, acuminate; 

 interval between mesosternal lobes feebly transverse, almost as wide as 

 the lobes themselves, the metasternal lobes subcontiguous. Tegmina 

 elliptical, about as long as the prozona. Fore and middle femora tuines- 

 rent in a slight degree; hind femora short and moderately stout, the 

 hind tibiae with nine spines in the outer series. Extremity of the 

 abdomen subclavate, well rounded, upturned, the margins of the sub- 

 genital plate of male with no basal ampliation, straight, the apex 

 broadly rounded, protruding beyond the tip of the supraanal plate by 

 less than half the length of the latter; furcula wanting; cerci com- 

 pressed, slender, subequal and nearly straight. 



The female being unknown, the description is based wholly upon the 

 male. 



The genus is represented by a single species' found in Mexico. 



CEPHALOTETTIX PARVULUS, new species. 

 (Plate III, fig. 1.) 



Pezotettix parvuUia McNEiLLl, MS. 



I'c-otettix olivacciix BRUNER!, MS. 



Blackish or fuscous bronze green above, olivaceous yellow below, 

 rather sparsely and not briefly pilose. Head above and sides to the 

 lower level of the eyes bronze green, becoming blackish above, with 

 the feeblest sign of a light-colored stripe behind the upper margin of 

 the eye; rest of head with face olivaceous yellow, feebly infuscated and 

 sparsely punctate: antennae olivaceous at base, testaceous beyond and 

 infuscated at tip. Pronotum wholly and almost uniformly dark bronze 

 green, a little darker above than on the lateral lobes, and slightly 

 darker on prozona than on- inetazona. Abdomen above fusco-olivaceous, 

 more or less ferruginous at the ends of the segments. Tegmina testa- 

 ceous. Fore and middle legs and hind femora olivaceous yellow, the 

 upper surface of the latter becoming fuscous in the apical half, the 

 whole geniculatipn blackish; hind tibiae green, the spines blackish 

 brown except at base. Supraanal plate of male triangular, broadly tec- 

 tiform except apically, the summit of the tectate portion with a rather 

 deep, slightly narrowing, basal sulcus half as long as the plate; furcula 

 absent; cerci slender, compressed but not laminate, tapering slightly at 

 the base, beyond equal, straight, feebly incurved and bluntly rounded 

 at the tip, angulate below. 



Length of body, male, 13.25 mm.; antennae, 6.75 mm.; tegmina, 2.5 

 mm.; hind femora, 8.5 mm. 



Two males. Otoyac, Vera Cruz, Mexico, 2,700 feet, December (L. Bru- 

 uer) ; Orizaba, Mexico, 4,000 feet, W. S. Blatchley ( J. McNeill). 



1 have preferred McNeill's name to Bruner's because the latter has 

 and the former has not been employed in closely related genera.
