Phytophaga Malayana. 21 



gitudinal rows of fine subremote punctures, visible only with a 

 lens. Scutellum semiovate, obtuse. Elytra much broader than 

 the thorax, parallel, their basilar portion indistinctly elevated ; 

 each elytron impressed with ten rows of deep distinct punctures, 

 the outer row sulcate ; interspaces plane in front, subcostate 

 towards the apex, each impressed with a row of fine punctures ; 

 external half of outer disc obsoletely wrinkled transversely; 

 hinder thighs ampuliate, much shorter than the abdomen, mode- 

 rately incrassate. 



Var, A. In this variety the head and thorax (with the exception 

 of an obscure patch on the vertex of the former) are concolorous 

 with the elytra. 



24. Lema cccruleata, n. sp. 

 Elongata, parallela, caerulea, nitida ; antennis modice robustis, 

 subfusiformibus, basi excepts, nigris ; thorace elongatulo, 

 medio valde coarctato, dorso Isevi, disci medio subtilissime 

 punctato, ante basin transversim sulcato ; elytris infra basin 

 transversim depressis, distincte punctato-striatis, striis ad 

 apicem distinctis, interstiiiis planis, ad apicem paullo con- 

 vexiusculis. 

 Long. 3 lin. 

 Hab. Tonda. 



Neck deeply constricted behind the eyes ; face triangular ; 

 forehead impressed with a longitudinal groove; eyes deeply 

 notched ; antennee nearly two-thirds the length of the body, 

 moderately robust, slender at the base, slightly tapering at their 

 apex, third and fourth joints equal, each rather shorter than tlie 

 fifth. Scutellum subtrigonate, its apex impressed with a deep 

 fovea. Elytra nearly four times the length of the thorax, sides 

 parallel ; subcylindrical, broadly depressed below the basilar 

 space, the latter obsoletely elevated. Abdomen clothed with very 

 short adpressed sericeous hairs ; hinder thighs scarcely thicker than 

 t!ie others, extending slightly beyond the second abdominal segment. 

 Very near in form and colour to the blue variety of L. Bow- 

 riugii, rather larger than that insect, the apex of the antennae 

 black, the transverse sulcation on the thorax less deeply im- 

 pressed.
