the punctures on the sterna rather widely separated, those on the "abdomen a little 

 closer together. 



Chevrolat's type is now in the British Museum.

This species is closely allied to A. prionurus, but is distinguished by the elytra 

 having a distinct subcosta and by the two white spots near the apex being directed 

 towards the suture anteriorly, while in A. prionurus they are nearly parallel or directed 

 outwards anteriorly. The metathoracic episterna are smooth on the inner margin, 

 closely and finely punctured on the outer margin. The prothoracic episterna are 

 clothed with nearly white pubescence and there is a somewhat large whitish spot on 

 the side of the third abdominal segment. 



The female example has a small white spot at the side of the elytra, rather behind 

 the middle.

 thorace disco eeneo-nigro, tenuiter punctato, leviter bi-impresso, lateribus sat profunde impressis, macula 

 flava ornatis ; elytris cyaneo-seneo-nigrescentibus, sat crebre evidenter punctatis, maculis quatuor aureo- 

 flavo-pubescentibus ornatis ; prosterno ruguloso ; metasterno sat crebre subtiliter punctulato ; episternis 

 intus laevibus, extus crebre subtiliter punctulatis ; abdomine sat crebre subtiliter punctulato.

Hab. Beitish Hondueas (Blancaneaux) ; Guatemala (Brit. Mus.). 



Closely allied to A. prionurus, but of different form and colour, and distinguished 

 moreover by the two shallow but distinct impressions on the disc of the thorax. The 

 impression on the front of the head is not very deep, and occupies about one third the 

 width ; the punctures immediately above the clypeus are united by short curved lines. 

 The thorax has at the posterior angles a short, smooth, oblique ridge. The elytra are 

 somewhat deeply impressed at the base, the impression being rugose and marked with 

 a spot of golden pubescence ; the subcosta is not very strongly marked.
