234 MR. MARTIN JACOBY OX [Feb. 16, 



Lema humeronotata, sp. n. (Plate XYII. fig. 2.) 



Black ; head and thorax dai-k feneous, closely punctured ; elytra 

 deeply punctate-striate, lolackish feneous, the shoulders with a 

 subquadrate fulvous spot ; base of the tarsi and of the antennae 

 testaceous. 



Length 3 millim. 



Head with a deep longitudinal central groove, obscure seneous, 

 finely punctured, eyes very large and subglobular ; antennae 

 gradually thickened towards the apex, the second to the fifth joint 

 gradually lengthened, terminal three joints shorter again, the base 

 of each joint fulvous ; thorax not longer than broad, the sides only 

 slightly constricted near the base, obliquely widened towards the 

 apex, anterior angles not prominent, the base with a shallow 

 transverse sulcus, the surface finely and closely punctured ; scu- 

 telhxm black ; elytra with a deep depression below the base, 

 strongly and closely punctate-stria te, the ninth row of punctures 

 entire, the interstices raised at the sides and apex, dark seneous, 

 the shoulders with a subquadrate fulvous spot, extending inwards 

 to the fourth row of punctures ; tarsi slender, pale testaceous or 

 fidvous, darker at the apex of each joint ; antei'ior tibiae obsciire 

 fulvous. 



Hah. Malvern, Natal {C. Earlier). 



Of this pretty little Lema Mr. Barker sent a single specimen ; its 

 system of coloration and the shape of the thorax will distinguish 

 it from every other except L. pauli Weise, with which I should 

 have identified it but for the following diflierences. Weise deseril )es 

 the thorax of his species with a distinct transverse ridge in front 

 of the basal stripe (I suppose by the latter is meant the sulcus) ; 

 of this no trace can be found in the present species ; the general 

 shape of the thorax is not given nor the stiiictvire of the antenna:* ; 

 the elytra are described as blue and the humeral spot as beginning 

 very narrowly at the base ; the opposite is the case in the species 

 described here, where the humeral mark is of nearly equal width, 

 except at the lateiul margins, where it is slightly lengthened. In 

 Weise's species the elytral depression is also described as obsolete ; 

 in the Malvern species it is deep. 



Lema icterica Weise. 



Three specimens obtained at Malvern, Natal, and kindly sent 

 by Mr. Barker, I must, for the present, refer to this species 

 (Archiv f. Naturgesch. 1901, p. 160), as the insect is evidently a 

 most variable one. The structural characters and the sculpture 

 agree very neai'ly with Weise's description, but not the coloration ; 

 in the type the clypeus and labrum are described as black. In 

 the Malvern specimens these parts ai'e flavous, all three -^-arying 

 in coloration as follows : — 



No. 1 . Flavous ; antennae black, the basal joint flavous ; thoi-ax 

 with a greenish-black lateral stripe at each side ; elj'tra with the 

 greater portion of the disc dark aeneous, only a basal spot and a 

 naiTow lateral stripe remaining flavous.
