and the weaker one is very small in one of my examples but normal 

 in the other ; in the latter the hind tibite are also plainly mucronate 

 underneath at apex. 



There is a little discrepancy between this description and that 

 of Burmeister, who says that the clypeus is quadri-dentate, and 

 the teeth of the anterior tibiae very obtuse. The first might be 

 a /«2JS?6S calami, the other an accident. My example was labelled 

 by Drege under this name. This species resembles P. semivirgatus, 

 but the head is more finely granulose, and the prothorax is equally 

 and also more finely scabrose right to the base ; the shape of the 

 clypeus is also different, being plainly tri-dentate. This last feature 

 gives it also the appearance of a species of Goniaspidius , from 

 which, however, it is distinguished by the short, obtusely triangular 

 scutellum.

Platychelus unguiculatus, n. spec. 



Black, with the elytra and legs red, shining; head and prothorax 

 clothed with villose sub-flavescent hairs ; elytra moderately densely 

 pubescent ; the pubescence is somewhat greyish, but along the 

 suture and the apical margin there is a band of denser and longer 

 white hairs turning to yellow on the apical margin; pygidium 

 clothed with very dense, appressed flavescent squamose hairs ; 

 clypeus sharply angular laterally, head and prothorax closely 

 scabrose ; scutellum clothed with long, dense white hairs ; the 

 elytra are punctate, impressed longitudinally along the humeral 

 callus ; the propygidium, abdomen, pectus, and legs are clothed 

 with greyish or white hairs ; the anterior tibicB are strongly tri- 

 dentate outwardly, the teeth are very sharp, and the apical one is 

 broadly separated from the other two, which are nearly connate ; 

 the hind claws are double and deeply cleft, the two parts of the 

 fissured inner claw which is cleft to beyond the median part being 

 equal in length and nearly so in thickness. The two sexes are alike. 



In no other species of the group to which P. unguiculatus belongs 

 is the cleavage of the inner claw so greatly developed. 



Length 5-6 J mm. ; width 3-3|- mm.

Platychelus hottentotus, n. spec. 

 Shape and sculpture of P. unguiculatus, but somewhat more 

 robust ; the shape of the clypeus is the same, the prothorax is
