carina with the reflexed part of the clypeus ; prothorax sub- vertical 

 in front in the male, w^ith the anterior part excavated and the upper 

 margin of the excavation forming an overhanging ledge sinuate in 

 the middle, or in the middle and on the sides according to the 

 development, and with the angles of the emargination acute, almost 

 dentate especially in the centre, this excavation is almost smooth, 

 but slightly villose inwardly along the upper ledge, and the posterior 

 and lateral parts of the disk are covered with round, moderately deep 

 punctures, rarer and less closely set in the median part, in the 

 female the prothorax is simple but has a faint marginal impression, 

 the punctures are also denser ; scutellum with a few faint punctures 

 in the male, but deep ones in the female ; elytra elongate, somewhat 

 depressed, covered with round but shallow seriate punctures, and 

 having on each side three distinct double rows representing the 

 striae ; propygidium, pygidium, abdomen, legs, and sternum densely 

 villose ; inner claw of anterior tarsi cleft into two divaricating teeth 

 carinate at base. 



Length 12-21 mm. ; width 7-10 mm. 



This species is crepuscular or nocturnal. It is found in the old 

 heaps of accumulated fteces brought out of the underground termite 

 nests Hodotcrmes havilandi. I found the larva also there, and also 

 another Dynastid SyrichtJms vents.

Pychnoschema diversa, Yv.S|»- 

 Plate XL., fig. 23„ P'^- ^^• 



A close ally to Pychnoschema corydon, but distinguished, however, 

 by the shape of the genital armature and the following characters : 

 the colour is piceous black, seldom piceous red on the elytra ; the 

 clypeus and the cephalic horn are similar except that the latter is 

 not so much hooked at tip in the large development, the genge are 

 narrower and are produced into a triangular process projecting much 

 beyond the eye and carinate in the middle ; the prothorax is more 

 oblique laterally in front in the male, the median excavation is not 

 so declivous and has no trace of an overhanging sinuate ledge, and 

 the posterior part of the disk is less sloping ; the elytra are not so 

 plane in the anterior part, and the punctures are broader, deeper, and 

 more closely set in both sexes. 



Length 13-17 mm. ; width 8-9 mm.
