is closely allied to S. infantilis, but is differentiated by the shape of 

 the genital armature.

Boheman's co-type of S. oblonga does not differ in any appreciable 

 degree from S. affinis, except that the clypeus is a little more arcuate, 

 but this character seems to vary somewhat in individuals of the 

 same species.

Shape, size, colouring, and sculpture of S. affinis, the punctures of 

 the prothorax are only slightly deeper. But in spite of this great 

 resemblance to S. affinis, the difference in the shape of the genital 

 armature of the males of the two species is very great (vicl. pi. li., 

 figs. 63, 66) ; the clypeus is blunt in front instead of being semi- 

 circular, and the last abdominal segment is somewhat broad and 

 swollen.

SCHIZONYCHA IGNAVA, n. Spec, 



Plate XLIIL, fig. 56. 

 Pale testaceous, but with the head, prothorax, and legs light 

 testaceous-red ; clypeus blunt in front, hardly sinuate, but with the 

 sides broadly rounded, carina transverse, plainly sinuate in the 

 centre, no suture, basal carina sharp, projecting triangularly in the 

 middle, the clypeus is closely foveolato-punctate and the frontal 

 part plainly asperous ; club of antennae long in the male ; prothorax 

 ampliated laterally and rounded slightly past the median part, very 

 much less attenuated thence to the sharp basal angle than in the 

 anterior part, covered laterally and broadly along the anterior 

 margin with closely set, asperous punctures, but on the discoidal part 

 the punctures from about the median part to the base are round 

 and non-asperous, «in the centre of the disk there is an elongated 

 smooth patch ; scutellum pluri-punctate on each side ; elytra 

 moderately elongated, slightly ampliated laterally before the median 

 part, deeply punctured, the diameter of the intervals lesser than 

 that of the punctures, and coriaceous in the dorsal part ; pygidium 

 with moderately closely set punctures, leaving a median smooth 

 longitudinal band ; penultimate abdominal segment slightly broader
