18 CHBTSOMELID^E. 



26. Lema semiregularis, sp. n. 



Fulvous ; labrum black ; elytra metallic violaceous ; underside 

 and legs fulvous. 



Vertex of head triangularly raised, very slightly grooved, the 

 base not constricted behind the eyes ; labrum black ; antennae 

 very long and slender, the third joint shorter than the fourth, 

 terminal joints very elongate. Thorax moderately constricted at 

 the sides, the anterior portion not much widened, the basal sulcus 

 very deep; the surface impunctate, fulvous. Scutellum fulvous. 

 Elytra with a short but rather deep depression below the base 

 and there very strongly punctured, with the interstices trans- 

 versely wrinkled, the puncturation as usual, gradually finer 

 posteriorly yet very distinct. Beneath and the legs fulvous. 



Length 6 mm. 



Hob. Mauipur (Doherty). Type in Brit. Mus. Malabar coast 

 (CWZ. Jacdby). 



Amongst the fulvous species with blue elytra, the present form 

 may be known by the unequal size of the third and fourth joints 

 of the antenna? and the coarse puncturation at the base of the 

 elytra, which looks somewhat confused on account of the trans- 

 versely rugose interstices. A specimen with partly black elytra 

 does not seem to differ in any other respects, but two specimens 

 from Mahe (Malabar) in my collection are rather larger and more 

 robust, the vertex is more strongly raised and the punctures at the 

 base of the elytra are rather less confused ; but these differences 

 do not seem to me important enough to be considered specific. 



27. Lema malabarica, sp. n. 



Eufous ; the antennae (basal joint excepted), clypeus, labrum, 

 apex of tibiae and the tarsi black ; elytra metallic blue, extreme 

 apical margins fulvous. 



Head impunctate, intraocular space highly raised and deeply 

 longitudinally divided ; eyes acutely notched ; clypeus and labrum 

 black ; antennae with the basal joint rufous, the following five 

 joints black (the rest in the type and only specimen wanting), 

 third and fourth joints equal, twice as long as the second joint. 

 Thorax broader than long, the anterior portion strongly transverse, 

 the angles prominent but not tuberculate ; basal sulcus deep, 

 sinuately widened at the lateral constriction but not forming a deep 

 excavation nor bounded by a ridge above ; surface with a few 

 minute punctures on the middle. Scutellum fulvous. Elytra 

 feebly transversely depressed below the base, closely and deeply 

 punctured, the punctures round, the spaces dividing them much 

 smaller at the basal portion than the punctures, the latter gradually 

 diminishing in size posteriorly. 



Length 5 mm. 



Hob. Malabar: Mahe (Coll. Jacoby). 



To be separated from other very similarly coloured species 

 with black clypeus and labrum by the colour of the tibise and the 

 tarsi and by the closely approximate large punctures at base of 

 elytra in connection with the general size.
