EUPLECTINI 79 



mentum; laterally the ventral surface is sharply limited each side by a carina, 

 from eye to basal margin posteriorly and from eye to base of mandible 

 anteriorly. The cervicum is subcontinuous with the ventral surface of the 

 head, but dorsally is separated from head by an abrupt, deep, arcuate sulcus. 



Maxillary palpi four-segmented, first segment short; second long, sinuate, 

 basally slender becoming strongly inflated apically ; third short, ovate-triangu- 

 lar, as wide as apex of second; fourth longer than second and wider than third, 

 fusiform, with mesial face inflated, and bearing a short palpal cone. 



Antennae eleven-segmented, proportions as given above, I elongate- 

 cylindrical, II obconical. III to VIII submoniliform. III to VI with length and 

 width equal, VII and VIII slightly transverse, narrower than II; club (IX, 

 X, XI) large and conspicuous, IX trapezoidal, X transversely trapezoidal, XI 

 basally truncate, conical. 



Pronotum (PI. VIII, 10) anteriorly narrowing and then suddenly obliquely 

 dilated to form a very short collar at the extreme anterior margin for the re- 

 ception of the broad cervicum; disc crossed by a deep, subentire, longitudinal 

 median sulcus and a deep, subentire transverse subbasal sulcus; a large 

 circular fovea athwart the transverse sulcus, on each side, about midway be- 

 tween margin and median pronotal point; sides each with six teeth, the first 

 basal, the second opposite the transverse sulcus, four more between transverse 

 sulcus and anterior fourth, decreasing in length and thickness from the third 

 spine on each side, sixth small, denticulate; basal margin thin, slightly raised, 

 with a median longitudinal carina for a short distance, this carina merging 

 with the longitudinal sulcus. 



Each elytron with an entire sutural stria, the sutural angle being slightly 

 produced into an acute tooth; shorter along suture than along flank; base 

 with four large foveas, decreasing in diameter from sutural to lateral; two 

 vague, short dorsal depressions, not reaching middle of elytron; humeral angle 

 prominent, obliquely elevated but rounded, not dentate; a long carina parallel 

 to elytral margin, far down on the flank, but no subhumeral fovea. 



Abdomen strongly margined, proportions of tergites and sternites as given 

 in measured lengths above. First tergite with a small but stout tubercle on 

 each side of the disc, well within the margin, near the base. First sternite 

 strongly produced and elevated between the posterior coxae, as a narrow, 

 elongate-triangular platform. 



Prostemum flat, glabrous, separated from pronotum on each side by an 

 obtuse, arcuate carina; no median longitudinal carina; a pair of large, deep, 

 circular lateral prosternal foveae at base, between coxae. Mesosternum simple. 

 Metasternum medianly and weakly sulcate. 



Anterior coxae long, conical, prominent, not contiguous; middle coxae 

 short, contiguous; posterior coxae short, massively conical, slightly separated. 

 Anterior femora strongly inflated, and with a high, thin, lamina-like carina 

 on the anterior- ventral face in the distal third; middle and posterior femora 

 not as strongly inflated. Tarsi three-segmented, with the first segment small 

 and other two tarsomeres much larger, the second being longer than the third.
