40 CHBYSOMELIDJE. 



Length 5 mm. 



Hab. Malabar: Mahe (Coll. Jacoby).

 elytral depression and differently coloured underside. 



73. Lenia rngifrons, Jac. Ann. Mus. Civ. Genova, xxvii, 1889, p. 151. 

 Pale testaceous ; labrum, antennae (basal and apical joints 



excepted) and tarsi fuscous. 



Head broader than long, not constricted posteriorly ; eyes 

 large and deeply notched, intraocular space not raised, with a 

 short central groove, finely rugose and pubescent ; labrum black ; 

 antennae with the basal and apical joints fulvous, the others 

 fuscous, third and fourth joints equal. Thorax slightly broader 

 than long, the sides with a rather deep excavation, the latter 

 joined to the basal sulcus which is deep and placed near the 

 base, anterior portion rather strongly widened, with another 

 transverse sulcus at each side ; the surface impunctate or with a 

 few fine punctures at middle. Elytra without basal depression, 

 strongly and closely punctate-striate, the punctures very closely 

 placed ; extreme apex of the tibiae and the tarsi more or less 

 fuscous. 



Length 4 mm. 



Hab. India: Calcutta; Burma: Eangoon.. 



The sculpture and pubescence of the head will at once separate 

 this species from any other placed in this section. 



74. Lenia feae, Jac. Ann. Mus. Civ. Genova, xxxii, 1892, p. 873. 

 Fulvous ; the breast and the abdomen (partly), black. 



Head not constricted posteriorly ; eyes large, deeply notched 

 and margined by deep lateral grooves ; lower portion of face 

 testaceous ; antennje fulvous, about half the length of the body, 

 the eighth joint slightly concave at its upper edge. Thorax 

 slightly broader than long, moderately constricted at the sides, the 

 disc with an anterior and posterior transverse sulcus, entirely 

 impunctate. Scutellum truncate at the apex. Elytra deeply 

 depressed below the base, deeply punctured within the depression, 

 the posterior portion more finely punctate, the punctures 

 surrounded by a piceous ring ; the interstices impunctate, strongly 

 thickened at the apex. Underside black, the last four abdominal 

 segments fulvous. 



Length 5 mm. 



Hab. Burma: Karennee. 



Can be known by the colour of the breast and abdomen, in 

 connection with the deep elytral depression.
