Pentodontoschema diversa, 

 Plate XL., fig. 14. 



Resembles small female examples of the preceding species, but it 

 is black ; the head bears a conical horn intermediate in length 

 between that of the male and of the female of P. aries, but the 

 clypeal carina is quite distinct ; the shape of the prothorax is similar, 

 and the sculpture nearly the same, although the punctures are a little 

 closer, but the two sinuatiens on the base are not so distinct, and in 

 the male the anterior part is not retuse nor excavate ; the elytra are 

 much more cylindrical, the striae are deeper but a. little narrower, and 

 the punctures which are similarly disposed in the strige and the 

 intervals are smaller, but they extend as far as the base, which is 

 seldom the case in P. aries ; the upper half of the pygidium is 

 aciculate and rugulose in the lateral part of the base ; in the male, 

 the only sex I know, the inner claw of the anterior tarsi is very dis- 

 tinctly bifid. 



Length 20 mm. ; width lOi- mm. 



Hab. Cape Colony (Uitenhage). 



Pentodontoschema fraudulenta, n. spec, 



Piceous black, shining ; facies intermediate between that of P. 

 capicola and that of P. nireus, but approximating more to that of the 

 former owing to the shape of the elytra which are diagonal laterally 

 from the shoulder to two-thirds of the length, where they are 

 ampliated ; the whole head is equally rugose, and the clypeus is bi- 

 de ntate, but there is no frontal tubercle, and the transverse carina is 

 distinct ; the prothorax is similar in shape and sculpture ; the striae 

 on the elytra are identical, but the punctures which in P. capicola 

 are numerous on the two first alternate dorsal intervals, are uni- 

 seriate in the present species ; the whole pygidium is covered in both 

 sexes with moderately closely set round punctures, has a narrow basal 

 aciculate basal band, and the basal corners are rugulose, there is no 

 excavation in the female ; the anterior tibiae have no intermediate 

 serrate tooth between the basal and the second digit, but whereas 

 in general facies this species approximates to P. capicola to such an 

 extent that it could be mistaken for it except for the differences 

 mentioned here, the genital armature of the male is almost entirely 

 similar to that of P. nireus, the only difference being in the shorter 

 and more broadly triangular emargination in the middle of the 

 penultimate joint which is also not grooved longitudinally on the
