Species of African Halticinie and Galerucinm. 37 



very short, moniliform, third and following joints very elongate, 

 rather longer than the basal joint ; thorax broader than long, the 

 lateral margins rounded at the middle, narrowed at the base, the 

 surface with a broad transverse sulcus at the middle, entirely 

 impunctate ; scutellum fulvous ; elytra much broader at the base 

 than the thorax, entirely impunctate, fulvous, the entire anterior 

 half black, the posterior portion with a transverse narrow black 

 band below the middle extending to both margins ; under-side and 

 legs fulvous. 



Hctb. Ogow6. {Collect. H. Clavarcau and my own.) 



In the apparently female specimens before me, the last 



abdominal segment is nearly entire or slightly sinuate ; 



the species is well distinguished by the impunctate elytra 



and their coloration. 



HemixantJia subrugosa, sp. n. (Plate III, fig. 18.) 



Testaceous, the antennse, the femora above and the tibije and tarsi 

 black ; thorax finely and irregularly punctured, the lateral margins 

 black, scutellum black, elytra deeply and strongly punctured, semi- 

 rugose, a sutural band of varying width and the margins narrowly 

 black. 



var. Elytra with tlie margins black only, the sutural band absent. 

 Length 5|-6 millim. 



Head impunctate, broadly impressed between the eyes, the vertex 

 pale fulvous, lower portion testaceous, the palpi black, frontal 

 elevations broadly trigonate, antennas filiform, black, the apical joint 

 fulvous, the third joint twice as long as the second one in the male, 

 shorter in the female, the fourth and following joints more elongate 

 and equal ; thorax less than twice as broad as long, the sides feebly 

 rounded anteriorly, with narrow margins, anterior angles slightly 

 thickened but not produced, the surface rather convex, with some 

 shallow irregular depressions at the sides, closely impressed with 

 larger and smaller punctures, the extreme lateral margins more or 

 less black, scutellum broadly rounded at the apex, finely granulate, 

 black ; elytra wider than the thorax at the base, subcylindrical, closely 

 and very strongly punctured, the interstices partly rugose, all the 

 margins and the epipleurae black, the suture sometimes with another 

 more or less strongly-marked broad black band, generally ill-defined 

 at the sides, sometimes entirely absent ; under-side and legs 

 testaceous, the upper edge of the femora and the tibite and tarsi 

 black.
