EUPLECTINI 105 



Head trapezoidal with rounded temporal angles; tempora rather long, 

 longer than eye; eyes small (0.04 mm. long), moderately prominent, composed 

 of about 22 small facets, the eye circular from a lateral view. Occiput broadly 

 arcuate with a median longitudinal carina extending from cervicum, across oc- 

 ciput, to a point posterior to a line passing through posterior margins of eyes. 

 Vertex with sides above eyes subgranulated ; two vertexal foveae which are 

 small, nude, circular, on a line through the posterior third of the eyes; vertexal 

 sulci beginning at a point lateral to and posterior of each vertexal fovea, and 

 converging in an arc to a point mesiad of each ant^nnal prominence, thence 

 being connected by a common transverse sulcus which passes posteriad of the 

 almost vertically declivous front. Head dorso-ventrally flattened from a lateral 

 point of view. Ventral surface of head nearly flat, subgranulated, with a large 

 nude circular gular fovea at middle of basal margin. Ventral surface with no 

 capitulate setae. Cervdcum ventrally polished and simple. 



Maxillary palpi well developed, four-segmented, first segment short and 

 cylindrical ; second about three times longer than first, distinctly more narrow 

 than first at base and inflated in apical half, slightly arcuate; third short, 

 wider than second, transversely triangular; fourth long (0.07 mm.), almost 

 twice as long as eye, oblique at base, minutely truncate at apex, subsecuriform, 

 with a small apical, palpal cone. 



Antennae eleven-segmented, widely separated at base by about one half 

 of the width of the head; segment I subquadrate; II ovate, as wide and as 

 long as first, first and second segments distinctly wider than third; second as 

 long as third and fourth united; III obconic; IV to VII subspherical, with the 

 sixth segment slightly smaller than either the fifth or seventh segment; VIII 

 subpyramidal ; club well-formed of last three segments as follows, IX pyra- 

 midal, transverse, slightly wider than eighth; X pyramidal, transverse, slightly 

 wider than ninth; XI relatively large, as long as eighth, ninth, and tenth united, 

 eylindrico-globose, apically not acute, but rounded slightly. 



Pronotum obcordate, widest through middle, with the lateral margins 

 broadly rounded to apex and more angulated to base; each side with a large 

 subbasal fovea, and at middle a small rounded median subbasal fovea, these 

 three foveae connected by a transverse biarcuate subbasal sulcus; disk with a 

 free, deep, short, polished subcuneiform fovea. 



Elytra with the humeri not denticulate ; each elytron with an entire sutural 

 stria, no dorsal stria, four basal foveae; a well-formed subhumeral fovea which 

 lies apical to a subepipleural carina on each flank, this carina being parallel 

 to the elytral lateral margin. 



Abdomen with five visible tergites, but no basal discal carinae, the tergites 

 simple, subequal and very slightly diminishing in length, with the fifth slightly 

 shorter, and of a rounded-triangular form from a dorsal view. Six visible 

 sternites, the first short, triangular between the coxae, relatively heavily 

 pubescent; second to fifth progressively decreasing in length, with the fifth less 

 than one-half as long as the second; sixth sternite longer than fifth, subequal 

 in length to third, slightly flattened in median apical half, and sinuate to form
