216 MACRIMA SUnCOSTATA. 



limited behind by a deep transverse groove; elypeus thick- 

 ened, triangular; labrum and palpi testaceous; apex of jaws 

 black; antennae slender, elongate, the first joint very 

 long , slender and curved , thickened at the apex , second 

 joint very short , third dilated and flattened , fourth 

 longer than the third , widened at its base ; thorax one 

 half broader than long , narrowed at the base , the sides 

 rounded towards the apex ; surface impunctate , with a deep 

 transverse depression not extending quite to the sides and 

 interrupted at the middle by a narrow , short and slightly 

 raised space; scutellum obscure piceous; elytra a little wi- 

 dened posteriorly, closely aad very finely punctured , the 

 interstices closely but not strongly longitudinally costate , 

 the costae disappearing below the middle; posterior tibiae 

 mucronate; posterior first tarsal joint as long as the 3 

 following ones united ; claws appendiculate ; anterior coxal 

 cavities closed. 



The elytra in this species have each a pale longitudinal 

 stripe , more or less distinct , from the base to the apex ; 

 the description given above is that of the male insect. 



Macrima malayensis , n. sp. 



Breast black ; abdomen testaceous ; above pale flavous ; 

 thorax deeply transversely depressed; elytra finely punctu- 

 red, shining. — Length 2^\^ — 3 lines. 



Head impunctate; antennae two thirds the length of the 

 body, the fourth joint one half longer than the third; 

 thorax impunctate , impressed as in the preceeding species ; 

 elytra finely and closely punctured. 



The two specimens before me difi:er in the colour of the ab- 

 domen which is testaceous in one and black with the ex- 

 ception of the last 2 segments in the other; the specimen 

 which I refer to the female sex has a little more strongly 

 punctured elytra, the punctuation being slightly arranged 

 in longitudinal rows, but only seen under a strong lens. 



The present species may be distinguished from M. ahdo- 

 ?fotes from the Leyden JMuseum , "Vol. VI.
