28 HALTICA ELONGATA. 



llültira (Graptodem) elongata , u. sp. 



Elongate , black below. Above obscure dark violaceous 

 or greenish. Posterior portion of thorax finely punctured. 

 Elytra more distinctly , very closely and finely punctured , 

 each elytron with a longitudinal costa near the sides. — 

 Length 3 lines. 



Head impunctate at the vertex; frontal tubercles rather 

 flat and contiguous; carina acute and narrow. Antennae 

 scarcely exceeding in length the basal third of the elytra, 

 black, closely pubescent, the fourth joint slightly but 

 distinctly longer than the third. Thorax one half broader 

 than long, the lateral margins very slightly but rather 

 regularly rounded , straight near the extreme base , poste- 

 rior angles acute, anterior ones more indistinct; basal 

 sulcation moderately deep and sinuate, the space behind 

 it finely but distinctly and rather closely punctured , rest 

 of the surface extremely finely and irregularly punctate. 

 Elytra elongate , narrowed towards the extreme apex only, 

 the latter rounded, of a leaden bluish colour, extremely 

 closely and rather finely punctured, the interspaces form- 

 ing narrow obsolete longitudinal costae more or less 

 distinct ; a strongly raised costa extends from the shoulder 

 to below the middle where it disappears. Underside and 

 legs black with a very obscure bluish tint, closely covered 

 with yellowish pubescence. 



Specimens from Soepajang , Datar , Silago , Moeara La- 

 boe , Soeroelangoen , Koetoer and Mesauw (Sumatra-Expe- 

 dition) , a single one from Soekadana (I. C. van Hasselt). 



I do not think to err in separating this species from 

 the other described Eastern forms , on account of its more 

 elongate shape, peculiar leaden bluish colour, punctured 

 thoi'ax and costate elytra. 



These insects are very closely allied in colour and diffi- 

 cult to determine, accurate descriptions are absolutely 

 necessary to distinguish the different species , a short diag-
