LEMA. 41 



space undivided ; labrum piceous ; antennae long, black. Thorax 

 nearly subquadrate with an anterior and posterior transverse 

 sulcus, the latter not very deep, the disc entirely impunctate. 

 Elytra with a deep subquadrate sutural depression below the base, 

 the punctures not very deep at the base, gradually diminishing 

 posteriorly. Underside black, entirely glabrous, the last abdominal 

 segments margined more or less with dark fulvous. Legs black. 



Length 7-8 mm. 



Hob. Assam (Coll. Jacoby). 



This species, although closely allied to L. hcumatomelas, Lac., is 

 larger than the latter and the elytral depression is much deeper ; 

 the thorax also is somewhat longer ; from other similarly coloured 

 species the two thoracic depressions and the black underside will 

 separate the present insect. 



76. Lema pallide-testacea, Clark, App. Cat. Phytoph. 1866, p. 28. 



Pale testaceous ; labrum and antenna? black ; legs piceous. 



Head sparingly punctured at the vertex, with a deep central 

 groove, lateral sulci deep ; labrum black ; antenna? extended 

 slightly beyond the base of the elytra, third and fourth joints 

 nearly equal, intermediate joints elongate, terminal joints shorter. 

 Thorax with a few fine punctures at middle, the anterior angles 

 rather pointed, basal sulcus deep, anterior portion with another 

 shallow transverse groove. Elytra parallel, with basal depression, 

 the punctures round and distantly placed. 



Length 6| mm. 



Hab. East India. 



Described from a single specimen, now in the British Museum. 

 The species is of elongate, parallel shape, pale testaceous, with dark 

 antennae and legs and a bisulcate thorax. The exact locality of 

 this insect is doubtful as Clark gives only the above habitat, which 

 may mean any part of the East. 



77. Lema clypeata, gp. n. 



Fulvous ; the antennae, parts of the breast and the legs black. 



Head not constricted, the intraocular space finely punctured, 

 with a deep central fovea ; the emargination of the eyes and the 

 clypeus closely pubescent, the latter bluish-black ; antenna) black, 

 rather short, gradually widened at the terminal joints. Thorax 

 quadrate, the anterior angles with a small tubercle, lateral ex- 

 cavations deep, blackish, furnished with a ridge above, basal sulcus 

 deep, anterior sulcus distinct at the sides only, another narrow 

 transverse groove is placed below the basal sulcus near the basal 

 margin. Scutellum broadly ovate. Elytra subcyliudrical, dark 

 fulvous with a slight iridescent gloss, without trace of a basal 

 depression ; the punctures large and round, closely placed at the 

 base, where the interstices are also transversely rugose, the 

 posterior portion more finely and more closely punctured, the
