MANNOPHORUS, lee. 



The thorax is closely and moderately coarsely punctate and the scu- 

 tellum is moderately large, broadly triangular and nearly round behind.

 llab. Texas. 



Black, beneath sparsely pubescent, above not at all, thorax red, 

 elytra black or bluish black, densely punctate with two yellow elevated 

 lines on each. Varieties occur with lines shortened and with a black 

 spot on thorax. . (PI. II, fig. 14.) 



A variety has recently appeared on the Mexican Boundary in Texas 

 having the elevated lines of elytra black, smooth like the typical form but 

 without a trace of usual color. 



ENTOMOSTERNA, C'hev. 

 Closely resembling the preceeding in form and Isc/ino.neffiis in 

 coloration of elytra. The thorax is however rounded on the sides and 

 not narrowed in front, and is blue in color, quite bright in fresh speci- 

 mens, nearly black in old specimens. The vittce of elytra are quite as 

 bright as in Ischnocnemis.

AMANNUS, Lcc. 

 The characters of this genus have been well defined in the table of 

 genera. The species are as follows: 



Black, beneath gray, abdomen with shining denuded spots vittiger. 



Black, beneath testaceous except postpectus and legs black ; femora testaceous at 



base pectoralis. 



A. vittiger Lee. J. A. P. ser. 2, II, p. 24. Length .43 in. = iimm. Hab. 

 Llano Estacado, Texas and New Mexico. 



This insect is entirely clothed with pale pubescence except as indi- 

 cated above, and on the elytra which bear a narrow black dorsal vitta 

 abbreviated in front and have the suture and margin also blackish. The 

 thorax is punctured except an obsolete dorsal callus, and is narrowed in 

 front and rounded on sides. The elytra are closely punctured, obsolete- 

 ly bicostate and broadly truncate at apex. 



A. pectoralis Lee. 1. c. Length .27ins.= 8 mm. Hab. Fort Yuma Cal. Col. 

 The head is variegated with piceous, the vitta of the elytra testaceous, 

 clouded behind, and the the lateral margin fuliginose. The thorax is 

 cylindrical and the apices of elytra separately rounded. The general ap- 

 pearance of the species of this genus suggests Sphaetwihccus.
