10 SEEEICOENIA. 



punctured spots. On these dorsal costse may be seen here and there a single punc- 

 ture ; the lateral costse and strise, both being very deeply and irregularly punctured, 

 are much confused and interrupted ; but there are no finely punctured spots as in 

 P. monilis. The punctuation above and below is like that of P. monilis : i. e. the head 

 is very strongly punctured ; the thorax has strong punctures, which on the disk are 

 placed irregularly, the spaces between them being sometimes very little and at others 

 as much as three or four times the diameter of a puncture. The prosternal process is 

 deeply channelled on each side, with the middle convex and smooth. The femora, 

 sterna, and abdomen are all closely and very strongly punctured.

Hab. Panama (Boucard). — Colombia, Cartagena \ 



This beautiful species is one of the few which have the narrow portion of the posterior 

 coxee densely and finely punctured and pilose, whilst the inner or broader part is coarsely 

 punctured and shining. I have not seen this important character noticed.

9. Psiloptera cortesi.

 Lampetis polymita, Chev., Silb. Rev. Ent. v. p. 59. 



Hab. Mexico, El Cameron, Oaxaca (Salle) ; Nicaragua, Chontales (Belt). 



The specimen from Nicaragua may prove to be a distinct species ; the thorax is less 

 angular at the sides, the punctures are more regularly disposed, and the spots on the 

 interstices of the elytra are smaller and more punctiform.
