EUPLECTINI 95 



strong longitudinal carina which arises on the cervicum, crosses occiput and 

 ends just posterior, and between the vertexal foveae, this median carina ending 

 in a median vertexal foveae. Vertex, therefore, trifoveate including the paired 

 vertexal foveae which are on a line passing through middle of eyes. A long, 

 slightly oblique sulcus arises at each vertexal fovea and ends just mesiad of 

 each antennal insertion, not actually joining its fellow, but seeming to, as a 

 consequence of the raised frontal margin between antennae. Head between 

 lateral carina and sulcus moderately flat, slightly raised and slightly granu- 

 lated ; head between sulci slightly depressed and less punctate, not granulated. 

 Ventral surface of head coarsely, sparsely punctate, with a median basal gular 

 fovea; pubescence short, not capitate but is finely pointed and subprostrate ; 

 laterally carinated each side from base of mandible to posterior eye margin. 



Maxillary palpi four-segmented, first minute; second four times as long as 

 first, equal to first in width at base, and inflated to width of third apically; 

 third short, subtriangular; fourth widest and longest, obliquely truncate at base, 

 subacute at apex, bearing a small palpal cone. 



Antennae eleven-segmented, widely separated at bases, segments I and II 

 subequal in length, subquadrate, second narrower than first; III to VII narrower 

 than second, subequal in length and width; III obconic; IV, V, VI, VII, and 

 VIII submoniliform ; club gradual, of IX, X, and XI, these segments progres- 

 sively wider than eighth; IX and X transversely trapezoidal; X shorter but 

 much wider than second; XI as long as from eighth to tenth united, but not 

 forming the entire club. 



Pronotum with a large, transversely expanded median foveoid depression 

 between disc and basal margin, and a smaller lateral fovea each side slightly 

 more anterior and well within margin, these three foveae connected by a weakly 

 developed biarcuate transverse subbasal sulcus. Disc not medianly foveate or 

 modified. Lateral margins narrowing obliquely to apex, and more sinuately to 

 base, lateral margin with a short acute tooth opposite each lateral fovea, and 

 anterior to this tooth the margin is very finely and irregularly crenulated. 



Elytra with each elytron having a subbasal, transverse carina, this carina 

 being medianly briefly interrupted, the mesial half biarcuate and the lateral 

 half uniarcuate, so that the carina is triarcuate as a whole. Within each arc is 

 a shallow, rudimentary fovea, that is, a sutural, a discal, and a lateral fovea. 

 The lateral fovea under high magnification is seen to be in reality two vestigial 

 foveae, but this is difficult to discern. Flank with a strong longitudinal carina 

 which parallels the margin for apical three-fourths then turns mesiad abruptly 

 to end behind the humeral angle. No trace of a subhumeral fovea. Humeri 

 oblique and moderately prominent but not dentate. No dorsal stria of any kind. 



Abdomen distinctly margined. Five visible tergites, first four are subequal 

 and very gradually and progressively shorter; fifth very small and triangular. 

 Six visible stemites, first triangular between coxae, slightly longer than coxae 

 or subequal in length; second one-fourth than first medianly; third slightly 

 shorter than second ; fourth slightly shorter than third ; fifth medianly half as 

 long as fourth, posterior margin concave to enclose sixth ; sixth transversely fusi-
