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 costse of the interstices of the elytra are 

 extremely close and distinct, with the intervals between these costae 

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

 men slightly bluish black.

 ffab. Philippine Islands {H. Cuming). 



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 costse are 

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



Metriorrhynchus sericeus.

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

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

 short and stout ; the third joint, however, is very long. Thorax with
