lowing joints are more strongly dentate. Thorax pale yellow, the 

 sides much reflexed. Elytra with the basal third pale yellow ; each 

 elytron with eight costse, the alternate ones less elevated ; the inter- 

 stices with rather close transverse punctures. 



Metriorrhynchus cribripennis. 



(Plate XIII. fig. 6.) 



Niger, subtus nitidus, supra opacus ; thorace septemareolato, 

 ochraceo ; scutello ochraceo, apice fortiter excise ; elytris ochraceis, 

 thorace latioribus, apicem versus paulo latioribus, quadricostatis, 

 interstitiis biseriatim confertim transverse costatis, seriebus costa 

 tenui divisis. Long. 10 lin. 



Hab. Ternate, Batchian. 



This species is very distinct on account of the elytra being less 

 parallel than in any of the foregoing, slightly widened towards the 

 apex. The transverse costae of the interstices of the elytra are 

 extremely close and distinct, with the intervals between these costse 

 scarcely as much as the thickness of the costae themselves. Abdo- 

 men slightly bluish black.

M. cribripeiDii affinis ; angustior, thorace paulo longiori ; scutello

 Hab. Philippine Islands {H. Owning). 



Very close to the preceding, but rather narrower, of a rather 

 deeper ochraceous colour, the thorax a little more elongate, the me- 

 sial areolet narrower. Scutellum narrowed towards the apex, deeply 

 but more narrowly excised at the apex. Elytra similarly sculptured 

 to the preceding ; but the elytra being a little narrower, the inter- 

 stices are narrower, and consequently the transverse costae are 

 shorter. The abdomen and sterna are brighter steel-blue-black. 



Metriorrhynchus sericeus. 

 (Plate XIII. fig. 5.) 



Elongatus, parallelus, ater ; anteunis brevioribus ; thorace, scu- 

 tello elytrisque ferrugineo-ochraceis, his parallelis, octocostatis, costis 

 intermediis parum elevatis, interstitiis crebre transverse costatis ; 

 abdomine nigro-cyaneo. d , $ . Long. 7-9 lin. 



Hab. Java (J. C. Bowring, Esq.). 



An elongate, parallel species, with rusty yeUow thorax, scutellum 

 and elytra, and blue-black abdomen. The antennae are unusually 

 short and stout ; the thii'd joint, however, is very long. Thorax with
