Since my last papers on African Phytophaga in the Transactions 

 of the Entomological Society of London for 1895 and in the 

 'Deutsche entom. Zoitschrift ' of the same year, a good deal of 

 new material bas come into my hands. M. Alloaud, of Paris, has 

 kindly submitted to me the Madagascar species obtained by him, 

 which, as the number of species was not large, I have included 

 here, although the fauna of Madagascar has little in common with 

 that of Africa, while Mr. Guy Marshall has been busy collecting 

 in Natal and Mashonaland with good results; and although not 

 much is gained for science, in my opinion, by continuing to add 

 new species to the already enormous material known and unknown, 

 it is to be hoped that one day we shall be enabled to work out 

 a Biologia of the country now under investigation, as has been 

 done in the case of Central America with such splendid results by 

 Messrs. Godman and Salvin. 



The present paper deals only with the Crioeerince, Cryptocephalin(F, 

 and ClytJirivce ; the other families I hope to deal with in a future 

 paper. Types of all the species are contained in my collection and 

 in that of the British Museum. 



Lema peinceps, n. sp. 



Eufous ; the antenna? (the basal joints excepted) and the tarsi 

 black ; thorax foveolate at the sides ; elytra metallic bright blue or 

 violaceous, deeply foveolate below the base, strongly punctate- 

 striate. 



Length 3| lines. 



Head impunctate, bituberculate between the eyes, the clypeus 

 and labrum black ; antennte long and slender, black, the lower five 

 joints rufous, the fourth joint one-half longer than the third one, 

 the fifth very elongate ; thorax not longer than broad, the sides 

 moderately constricted, rather strongly produced above the con- 

 striction, the base with a deep transverse sulcus, a small transverse 

 fovea is also placed immediately above the constriction at the sides, 

 the disc with two roMS of punctures at the middle, some other 

 punctures also placed near the anterior angles ; scutellum fulvous, 

 not longer than broad ; elytra with a deep depression below the 

 base near the suture, bright metalHc blue, strongly punctate-striate, 

 the punctures slightly elongate and distinct to the apex, the inter-
