540 PROCEEDINGS OF THE ACADEMY OF [June, 



Strongly punctate; anterior margin subtruncate with a very slight 

 median emargination. posterior margin arcuate, the apex subtruncate; 

 lateral lobes longer than deep, the lower margin distinctly obtuse- 

 angulate. Prosternal spine rather short, blunt, slightly retrorse; 

 interval between the mesosternal lobes broader than long; interval 

 between the metasternal lobes quadrate. Tegmina equal to the pro- 

 notum in length, slightly less than two-thirds as wide as long, subattin- 

 gent; apical portion subacute, the apex itself rounded. Posterior fem- 

 ora moderately slender, slightly more than four times as long as wide ; 

 posterior tibiae with seven or eight spines on the external margin. 



General color bluish-black, variegated with orange-vermilion, orange, 

 lemon-yellow and apple-green. Head ornamented with orange ver- 

 milion on the posterior inferior portion of the gena, an infraocular 

 blotch, a line along the clypeal margin of the face, and a crude semi- 

 circle margining the posterior superior borders of the eyes and the 

 interocular space. Pronotum with the usual median crescent and the 

 short anterior median bar orange-vermilion, fading along the posterior 

 median bar into orange, which color decorates the posterior margin of 

 the pronotum, very broadly on the lateral lobes, narrowly on the disk. 

 Tegmina reticulate with apple-green. Abdomen with the dorsal 

 segments posterior margined with lemon-yellowy developed on the 

 median line into a series of triangular blotches which are connected by 

 a narrow line of the same color, an obscure lateral series of lemon- 

 yellow dots are also noticeable; ventral segments dull lemon-yellow 

 with the bluish-black reduced to a series of lateral basal spots, and a 

 broad triangular basal spot on the subgenital plate. Prosternal spine 

 lemon-yellow; mesosternum and metasternum dirty luteous. Ante- 

 rior and median femora with a median or premedian blotch of orange- 

 vermilion. Posterior femora with three broken bars of lemon-yellow, 

 one basal, one premedian, the other median; external face with the 

 scalariform impressions outlined with yellowy posterior tibiae blackish- 

 blue, the spines black apically.
