TLAOCEBA, n. gen. 



Mentum broad, rounded laterally, not clearly separated from the 

 broadly truncated, cone-shaped ligular part which is only half the 

 width of the hollowed mentum ; palpi inserted laterally, last joint 

 swollen, nearly fusiform ; maxillae robust, upper lobe somewhat con- 

 cave, laminate, emarginate at the tip, inner lobe very plain, sharp ; 

 maxillary palpi robust, apical joint swollen, strongly fusiform out- 

 wardly, less so inwardly ; mandibles strong, arcuate at the tip, com- 

 pressed inwardly on each side, not membranaceous at the base ; 

 antennae 10-jointed, the sixth and seventh joints compressed, the 

 latter projecting slightly in the inner part, club tri-jointed, as long 

 as the pedicel, joints laminate, straight outwardly but ampliated 

 inwardly ; clypeus semicircular in front, slightly shorter than the 

 head and separated from it by a strongly bi-sinuate, shallow suture, 

 broadly perpendicular in front with the anterior margin much 

 reflexed, labrum well-developod, deeply incised ; prothorax little 

 convex ; plainly ampliated and rounded laterally in the middle, 

 bi-sinuate along the base with the outer angles not sharp, but also 

 not rounded, strongly depressed in the anterior part (male) ; elytra 

 sub-parallel, not convex on the upper side, projecting beyond the 

 propygidium and pygidium, the latter vertical ; anterior tibiae tri- 

 dentate, and with a long inner spur ; intermediate and posterior 

 ones with an oblique carina on the outer side, apical part of the 

 latter somewhat dilated, spurs long, but not very sharp ; tarsi longer 

 than the tibiae, stiffly bristly at apex, claws long, curved, and having 

 a juxta-basal, short, vertical tooth underneath. 



I propose this genus for a singular insect, the prothorax of which 

 is strongly impressed on the anterior part, and having a tubercle on 

 the frontal part, in the manner of a $ Pachypus ; the general facies, 

 however, is not unlike that of Achloa. 



Tlaoceea saga, n. spec. 



Male : Black, with the elytra and antennae chestnut-brown, frontal 

 part, prothorax, scutellum, pectus, and femora clothed with long, 

 dense fulvous hairs ; clypeus semicircular in front, straight laterally, 

 concave, having a double row of deep punctures on the anterior part, 

 but smooth along the suture, frontal part deeply punctured, each 

 puncture bearing a long hair, plane, and having a sharp, compressed, 

 somewhat longitudinal tubercle in the centre ; prothorax broadly and 

 somewhat deeply impressed in the anterior part, which is also a little 

 more closely punctured than the posterior part where the punctures
