TRIBE ANTHIINI. 

 GEN. POLYHIEMA, Chaud. 



POLYHIRMA COMMISTA, 11. sp. 



Black, moderately shining; head with a greenish-white pubescence 

 continued as a median band along the neck, the median part of the 

 prothorax and the scutellary region, and having also an apical median 

 patch on the elytra, the sides of the sternum are moderately densely 

 hairy ; prothorax cordiform very closely and somewhat roughly 

 punctate ; elytra elongated and having on each side in addition to 

 the supra-marginal carinule seven very sharp keels, the sixth of 

 which begins only at about three-fourths of the length, these keels 

 reach from the base to a short distance from the apex in both sexes, 

 and the intervals are very deeply alveolate, the bottom of the alveolae 

 is black, the basal part is not alveolate for about one-eighth of the 

 length, and the median hairy whitish band reaches only as far as 

 that. 



This species is closely allied to P. mad leu ta, and differs only in 

 the background of the alveolae not being fulvous. It might be con- 

 sidered as a mere variety of the former, which, however, it replaces 

 in Southern Ehodesia north of Buluwayo and in Damaraland and 

 Ovampoland, and it is therefore entitled to be considered as a valid 

 species. 



Length 20-224- mm. ; width 5f-6i mm. 



Hab. North- West Damaraland; Ovampoland; Southern Ehodesia. 



TEIBE CHL.ENIINI. 



GEN. CHL/ENIUS, Bon. 

 CHL^NIUS DITULUS, n. sp. 



Head and prothorax bronze green, shining, elytra bluish-green 

 with an elongated rufescent band extending from the third to 

 the eighth stria, beginning slightly past the median part and 

 reaching the apex, antennae fuscous with the three basal joints 

 reddish, legs and tarsi red ; head aciculate with the median part 

 smooth ; prothorax very elongato-ovate, as broad at the apex as at 

 the base, covered with deep, nearly contiguous and moderately 

 broad punctures ; elytra narrow, elongated, the humeral part 

 strongly rounded, intervals very deeply and closely punctured,.
