 the general facies is that of P. aries.

Smaller than the preceding and black above, but chestnut-brown 

 beneath, and with the whole pectus clothed with fulvous hairs ; the 

 elytra are also a little more ampliate nearer the median part laterally, 

 but they appear so because there is no slight supra-lateral depression 

 as in P. capicola; the median part of the clypeus is rounded and not 

 dentate laterally, the carina is transverse, and distinct, but although 

 a little raised in the centre it is not tuberculate, the sculpture of the 

 head is identical ; the prothorax is attenuate laterally in front, but 

 although rounded from the median part to the basal angle, it is very 

 little attenuate there, the base is much less distinctly sinuate on each 

 side, and the punctures are much deeper and more conspicuous ; 

 striae of elytra deeper and also more deeply punctured, the punctures 

 on the intervals disposed in a single row ; prosternum closely and 

 deeply punctured but with a narrow basal transverse band finely 

 aciculate ; anterior tibiae with only a serrate tooth above the digita- 

 tion ; inner claw of anterior tarsi moderately developed, and very 

 feebly bifid laterally near the tip. 



Length 16-17 mm. ; width 9-11 mm. 



The shape of the genital armature is quite different from that of 

 the other species, except that of H. deceptor.

Pentodontoschema deceptoe, n, spec, 

 Plate XL., fig. 16. 



This species is so closely allied to the preceding that it can hardly 

 be differentiated without examination of the genital armature which, 

 although shaped somewhat alike, is very different ; the head is 

 similar in shape and in sculpture, but the punctures on the prothorax 

 are deeper and slightly more closely set on the sides and in front, 

 and the punctures on the strijB of the elytra are very much less 

 distinct especially on the sides, the elytra themselves have a more 

 cylindrical appearance, and the pygidium is not quite so large, but
