26 Phytophaga Mulayana. 



33. Lema Sumatrensis, n. sp. 



Elongata, subcylindrica, rufo-ferruginea, nitida, subtus aureo- 

 sericea; antennis filiformibus, pallidis, dimidio corporis longi- 

 oribus ; thorace elongatulo, medio profunde coarctato, dorso 

 laevi, basi non impresso ; elytris parallelis, nigro-caeruleis, 

 infra basin late transversim impressis, tenuiter punctato- 

 striatis, striis ad apicem distinctis, interspatiis planis, singulis 

 serie unica punctorum minutorum impressis; tibiis apice 

 fuscis, ungLiiculis nigris. 



Long. 3g lin. 



Hab. Sumatra. 



Head triangular, apex of jaws and eyes black, the latter deeply 

 notched ; antennae moderately robust, nearly two-thirds the length 

 of the body, filiform, joints cylindrical. Thorax rather longer 

 than broad, sides deeply constricted ; upper surfiice without any 

 basal depression or sulcation, middle of disc impressed with a few 

 very fine punctures, which are only visible under a lens. Scutel- 

 lura trigonate, obscure rufous, its apex obtusely trunctate. Elytra 

 parallel, narrower than in L. Smifhii, convex, finely but distinctly 

 punctate-striate ; interspaces plane, each one impressed with a 

 single row of very minute punctures, which can only be seen 

 under a glass. Legs robust ; extreme apex of til)i8e fuscous. 

 Mesosternum elongate, sides sinuate ; apex curved, obtusely 

 rounded. 



Nearly allied to L. Smifhii, narrower, one-third less in size ; 

 from L. cyanipennis it may be known by the much finer punc- 

 tuation of the elytra, and by the different form of the apex of its 

 mesosternum; from L. cyanesthis it can at once be separated by 

 the different form of the thorax. 



34. Lema atripennis, n. sp. 



Elongata, subcylindrica, rufo-testacea, nitida; antennis filiformi- 

 bus, obscure fusco-fulvis, articulis intermediis nigris, oculis 

 profunde emarginatis ; thorace latitudine pauilo longiori, 

 lateribus valde coarciato, disco ante basin transversim sul- 

 cato, medio punctis sparsis minutis impresso; elytris nitido- 

 nigris, infra basin transversim depressis, basi pauilo elevatis; 

 punctato-striatis, striis integris, punctis ante medium magnis, 

 profundis, postice parvis, minus fortiier impressis, interspatiis 

 ad apicem convexiusculis. 



Long. 3 lin.
