2. Another Contribution to the Knowledge of African 

 Phytophagous Coleoptera. By Martijv Jacoby, F.E.S. 



[Received January 9, 1904.] 



(Plate XVII.*) 



The following descriptions are based on new species from 

 different parts of Africa and contained in my collection, which 

 were sent to me for identification by Mr. Cecil Barker of Malvern, 

 Natal, the Rev. J. A. O'Neil of Cape Colony, Dr. Brauns of the 

 same place, and Mr. Sheppard of Beira. The present paper deals 

 with the first groups as far as the Chrysomelincf ; the rest of the 

 Phytophaga will form the subject of another contriliution. 



CRIOCERINiE. 



Lema aveisei, sp. n. 



Underside and antennae and legs black, upperside dark brown ; 

 thorax with several rows of very fine punctures at middle of disc, 

 otherwise impunctate ; elj^tra with a, sutural depression at tlie 

 base, deeply punctate-sti-iate, the interstices costate posteiiorly. 



Length 7 millim. 



Head constricted behind the eyes, with two highly raised, 

 deeply divided, and sparingly pubescent tubercles, dai'k brown, 

 the anterior portion black ; eyes large and prominent, deeply 

 notched ; antennae not extending to the middle of the elyti'a, the 

 third and fourth joints equal, terminal joints slightly thickened ; 

 thorax scarcely longer than broad, the sides not sti'ongly con- 

 stricted, with the usual deep fovea which gradually diminishes 

 towards the disc, the base deeply transversely svdcate, the surface 

 with three or four rows of fine punctures at the middle, anterior 

 angles slightly tuberculiform ; elytra with a more or less deep 

 depression below the base near the suture, strongly punctate- 

 sti'iate, the first row of punctures double at the anterioi- portion, 

 the interstices near the apex strongly costate and closely approached ; 

 below finely pubescent. 



Hal). Lambarem, Fr. Congo (Coll. Belgian Mus. and my own). 



This is another and no doubt quite distinct species belonging 

 to the group of L. armata Lac, L. hottentota Lac, and L. macro- 

 dera Weise. The sculpturing of the thorax is quite difterent, 

 inasmuch as there is scarcely any punctuation excepting the 

 median rows, and these are very fine ; there is also an entire 

 absence of any transverse wrinkles, and the antennae are much 

 longer than in L. ce2)halotes Lac. " I have received several specimens 

 of this species from M. Clavareau. 



Lema cyaneoplagiata Jac. 



Var. Elyti-a metallic blue, the apex, in shape of a triaugulai- 

 spot, testaceous.
