Species of African HalticiniB and Galerucinie. 17 



their tibise widened at the apex, carinate but not sulcate ; proster- 

 nuni narrow, anterior cotyloid cavities closed. 



Hah. Malvern, Natal {C. Barher). 



On account of the structure of the antennae which have 

 their outer joints trianguhirly widened, the acute anterior 

 thoracic angles, non-sulcate tibioe and generally elongate 

 shape of the insect, this species agrees with Weise's genus 

 better than with Amjjhivicla to which it is allied by the 

 well-separated bases of the antennae. 



Ochrosis natahnsis, sp. n. 



Ovate, black, head, the antenn?e, thorax, and the legs fulvous, 

 thorax impunctate, elytra black, punctate-striate, the interstices 

 finely punctured. Length 2|mil]im. 



Head impunctate, fulvous, the frontal elevations both broad and 

 indistinct, labrum piceous, antennaj with short and rather robust 

 joints, the third more slender and slightly longer than the others, 

 terminal joints slightly stained with fuscas ; thorax transversely 

 convex, not much more than one-half broader than long, the sides 

 strongly rounded at the middle, the disc convex, entirely impunctate, 

 fulvous, at the base a very shallow transverse sulcus is placed (only 

 seen in certain positions) which gradually curves downwards at the 

 sides to the basal margin, scutellum black : elytra subcylindrical, 

 black, rather shining, strongly and regularly punctate-striate, the 

 interstices fiat, sparingly and very finely punctured, legs robust, 

 fulvous, the metatarsus of the posterior legs as long as the following 

 joints together, tibia) with a very small spine ; breast and abdomen 

 black, the posternum narrow, the anterior cavities closed. 



Hab. Ifafa Mts., Malvern, Natal (C. Barker). 



Ochrosis, Foud., appears to be the only possible genus for 

 the reception of this species, agreeing as it does with 

 the European representatives of the genus in the structure 

 of the thorax and its shallow sulcus which gradually joins 

 the base. It is the first recorded species from Africa. 



Chx-locnema dunhrodensis. 



sp. n. 



Dark feneous, very shining, the antenna? (the apical joints excepted) 

 and the legs flavous, posterior femora teneous, head and thorax 

 strongly punctured, elytra pointed posteriorly, strongly punctate- 

 striate, the interstices impunctate. Length 2| millim. 



Head broad, without oblique grooves, deeply but not very closely
