REVISION OF ELEODIINI BLAISDELL. 11 



distinctly constricted beyond the condyle. Joints eight to eleven, 

 inclusive, more or less densely and finely pubescent, with tactile 

 setse. All the joints are irregularly punctate, and from each punc- 

 ture arises a seta ; setae longer on the apical moiety of each. 



Right mandihle {Eleodes dentipes^ Plate 8, fig. 12) short, robust, 

 triangular, a little decurved at tip, the latter feebly emarginate. 



jSi/peiior surface feebly convex, divided by a feeble arcuate ridge 

 into an apical or incisive surface occupying al)out the anterior third, 

 and a basal or molar surface occupying the basal two-thirds. In- 

 cisive surface with a series of short parallel ridges near and at right 

 angles to the internal margin. 



External surface with outline quite strongly arcuate, most so in 

 apical half, which becomes apparently transverse ; divided by a 

 longitudinal ridge-like prominence into two parts, a superior and 

 an inferior, both feebly concave and finely scabro-punctate. Sur- 

 face at apex not concave. 



Ventral surface (Plate 8, fig. 10) deeply and arcuately excavated; 

 lacinia prominent, rounded and free anteriorly, finely pubescent. 



Internal surface (Plate 8, fig. 2) deeply concave within the incisive 

 third; lacinia prominent before the well-developed and transversely 

 oval molar, behind which is a membranous lobe; the latter is pubes- 

 cent, and the hairs longer than on the lacinia. Molar with a fine 

 elevated margin, the inclosed surface area feebly and irregularh?; 

 excavated. 



Left mandihle {E. dentipes) more strongly decurved apically and 

 more deeply excavated within; incisor margin slightly emarginate; 

 external surface at tip more strongly beveled from the emarginate 

 edge. As a whole it is less strongly arcuate and a little longer than 

 the right. 



Maxilla (E. dcfitipes, Plate 8, fig. 11). — The palpi are compara- 

 tively large and four-jointed. The basal joint small, quite strongly 

 and outwardly bent at middle; second joint elongate, obconical and 

 nearly twice as long as the third, the latter also obconical and slightly 

 arcuate at base; fourth broadly triangular, not equilateral, the inner 

 margin the shortest, the external and apical subequal. 



Lacinia ending in a chitinous claw-like point ; external surface con- 

 cave with nuirgins arcuately dilated at middle, adapted to the in- 

 ternal surface of the galea. The internal surface just basad to the 

 claw-like extremity is densely set w^ith rather long incurving cilia- 

 like setas elsewhere the surface is shining and very glabrous. 



Galea of one joint, subtriangular (variable in the different species) ; 

 external surface evenly convex and glabrous, limited apically b}^ a 

 dense and evenly transverse row" of rather short spinules, immediately 

 beyond which the apex is densely set with rather long, incurving 

 spinule-like cilia.
