for one row of short hairs along the outer margin of the coxge and 

 a few appressed ones on the sides of the metasternum and on the 

 somewhat broad episterna ; hind femora broad, hind tarsi short, also 

 broad, and with only three long, stiff, single bristles underneath. 



Length 7 mm. ; width 4J mm. 



Hab. Southern Khodesia (Victoria Falls). 



This species very closely resembles examples of Autoserica 

 annectens, but it is easily distinguished owing to the tri-dentate„ 

 tibiae and other specific characters. 



DIAPHOROSERICA, n. gen. 



Plate XLVL, fig. 3. 



Very closely allied to Gryphonycha, the chief distinctive characters 

 being the shape of the fore tarsi and claws of the male ; the former 

 are short, the second, third, and fourth joints are triangularly dilated, 

 the fifth is much broader and longer, the claws are conspicuously 

 diverging, each one is deeply cleft, the upper tooth of the left one 

 being very slender, and the lower very broadly lobate, this lobe is 

 conspicuously wider in the outer than in the inner claw ; in the 

 female the claws are deeply cleft, the lower tooth is, however, wider 

 than the upper ; antennae 9-jointed in both sexes, the 3-jointed club 

 is nearly as long as the pedicel in the male. The prothorax curves 

 very strongly forwards, and the • mentum is not as densely hairy 

 as in Gry phony cha. This genus differs from Neuroscrica, Brensk., 

 in both the anterior claws of the male being toothed and not 

 widened, lobe-like, and in the club not being strongly elongated. 



DlAPHOROSERICA MASHONA, n. Spec. 



Rufescent, with a fleshy tinge and a more or less strong opaline 

 sheen ; antennae testaceous ; clypeus with a plain frontal suture, 

 arcuately emarginate in front but with the margin reflexed and 

 slightly aculeate in the centre, the outer angles are distinct, but 

 not prominent, the surface is deeply punctured, the head less 

 so ; prothorax slightly narrowed laterally in front, sinuate behind 

 and also along the base, sloping forwards, vaguely punctulate only 

 along the base and sides ; scutellum long, aciculate ; elytra elongated, 

 plainly striato-punctate with the intervals sub-tectiform, the punc- 

 tures of the striae impinge on each side of the sub-tectiform intervals ; 

 anterior tibiae bi-dentate. 



Length 6-7 mm. ; width 3J-4 mm. 

 ' Hab. Southern Rhodesia (Sebakwe).
