Long. 1(3 mm,, elytr. 1U|, lat. o. 



Vertex with one blackish streak at each side behind the antennae, and witli 

 one or two behind the eyes ; the sparse white pubescence of the head denser 

 between tlie streaks. Tip of the antennal joints black ; the last five joints entirely 

 black, or with a reddish spot on the underside ; fourth and fifth joints, or only the 

 fifth, white underneath. The white pubescence of the prothorax denser anteriorly 

 and posteriorly between the streaks, aud especially so above the coxal cavities. 

 Punctures of the elytra coarse at the base, arranged in rows near the shoulders, 

 lieciimiug minute and sparse from behind the middle, and nearly wanting at the 

 apex. Elytra with a broad triangular blackish patch at the base, common to both 

 elytra, extending from the scutellum almost to the middle of the suture, aud 

 laterally so before the middle of the outer margins, with the humeral side somewhat 

 incurved; the shoulder angles, a transverse band liefore the apex, aud a small spot 

 at the suture behind the middle also blackish or brownish black ; the sjiace in 

 front of the ante-apical band bears an ill-defined triangular white jiatch, or some 

 small and more or less confluent white spots. Body beneath blackish laterally, 

 clothed with a sparse white pirbescence, forming spots on the sides, chiefly on the 

 abdomen. Femora Ijlackish, with reddish spots.

Closely allied to Armatosterna buquetiana (White) (in the Munich Catalogue 

 as Trwiocephala hu<iueticumm White), from which it is distinguished by the longer 

 tubercles of the prothorax, aud by the apex of the elytra being produced into a 

 long spine at the external angles ; the basal region between the shoulders and the 

 triangular patch has no white pubescence, and the dark jiatch itself is much better 

 defined in the new species.
