base transversely truncate ; apex very broarlly, feebly emarginate in the 

 middle three-fifths, receiving the base of the epistoma ; surface shining, with 

 a few erect dorsal sets, feebly and sparsely creased, having two oblique lines 

 of coarse feeble punctures in front of tlie middle, and three in the middle near 

 the epistonial margin ; side margins bristling with erect setse. Epistoma 

 trapezoidal, transverse, feebly declivous ; apex transversely truncate ; apical 

 two-fifths glabrous, shining, very feebly rugulose ; basal three-fifths densely 

 covered with small, robust, spiniforra tubercles. Labrum strongly transverse, 

 truncate at apex, having a loose fringe of short porrected setfe along the apex ; 

 surface broadly, very feebly convex, polished, glabrous, with a double line 

 of small, erect, very robust spines near the apex. Mandibles not prominent, 

 visible laterally ; surface flat ; outer margin broadly bilobed ; anterior lobe 

 with an elevated margin ; posterior with a double line of coarse, erect spines 

 near the lateral margin ; outer face bristling with erect, coarse setfe. Antennje 

 short, rather slender, four-jointed ; third joint obconical, shorter than the 

 second ; fourth small, subulate, enlarged and bulbous at base, the enlarge- 

 ment enclosed by the apex of the third joint. Maxillre well developed ; base 

 very large and prominent. Maxillary palpi rather slender, not compressed, 

 with three free joints, the basal being very short, broad, and anchylosed to 

 the supports; first free joint slightly longer than wide, truncate at apex, 

 slightly obconical ; second fusiform, distinctly longer than wide, broadly 

 truncate at base and apex ; third small, oblique, sides nearly parallel, twice 

 as long as wide, two-thirds as long as the second, apex truncate. Mentum 

 longer than wide, rather small, transversely, strongly convex ; surface setose, 

 granulose, also coarsely asperate ; gular peduncle trapezoidal, well marked. 

 Ligula slender, projecting far beyond the mentum. Labial palpi small, ap- 

 parently of two joints, terminal slender, oblique, much longer than wide. 

 Eyes wanting. 



Prothorax much longer than wide, slightly narrowed from apex to base ; sides 

 very feebly arcuate ; apex and base broadly, transversely truncate ; surface 

 cylindrical, having a double row of four small setigerous punctures near the 

 middle and extending from base to apex ; lateral suture inferior ; under surface 

 behind the coxae conical, ascending upward from the base, shining, glabrous 

 anteriorly, setose toward base. Legs far before the middle, short, robust, com- 

 pressed ; coxffi approximate, short ; basal joint triangular, with a few short 

 robust tubercles near the apex interiorly ; second larger, triangular, with a 

 double row of small tuberculiform spines along the inner apex ; third as long 

 as the second, longer than wide, with a row of long, erect, very strong spines 

 along the inner edge ; terminal claw very large, acuminate at apex. 



Mesothorax short, scarcely longer than wide, cylindrical, constricted at apex ; 

 surface with a few setigerous punctures anteriorly near the constriction, and a 

 more widely distant row near the base. Legs at the middle of the segment, 

 very small, rather robust. Surface before the coxje carinate in the middle ; 



remaining the one on the left represents the anterior leg with its coxa, and 

 that on the right the antenna.
