distinct here, are also present in C. cinerea. A good many specimens were received 

 from Guatemala, of which one is figured here. 



5. Chlamys sallaBi. (Tab. IV. fig. 23.) 



Oblong-ovate, above dark blue, pubescent ; head, posterior margin of the thorax, and the anterior legs bright 

 fulvous. 



Length 1-| line. 



Head scarcely visibly punctured ; antennae black, their four basal joints fulvous ; thorax of nearly the same 

 shape as in G. cinerea, very closely punctate, the anterior half dark bluish, the rest fulvous, this colour also 

 extending to the lateral margins ; elytra narrowed posteriorly, more strongly and more distantly punctured 

 than the thorax, with a narrow transverse tubercle behind the middle, and two others, more or less distinct, 

 situated respectively in front and behind the transverse one ; pygidium fulvous, with a large central blue 

 patch ; underside fulvous ; centre of the abdomen and the middle part of all the legs, with the exception 

 of the anterior femora, dark blue ; prosternum narrowed posteriorly. 



Eab. Mexico, Panistlahuca (Salle). 



6. Chlamys gerstseckeri. 



Subquadrate, dark blue and fulvous below, above bluish black, opaque ; thorax with a central band and the 

 lateral margins fulvous ; head entirely fulvous ; elytra rugose-punctate, with a transverse tubercle behind 

 the middle. 



Length 2 lines. 



Head fulvous, with a slightly impressed central groove ; antennae rather slender, as long as the thorax, fulvous, 

 the apical joints darker ; thorax with a moderately high elevation at the middle of the disk, surface closely 

 rugose-punctate and covered with very short and fine white pubescence, bluish black, the middle occupied 

 by a longitudinal bright fulvous band from the apex to the base, but narrowed to a point at the latter 

 place, the lateral margins also narrowly fulvous ; scutellum trigonate, impunctate ; elytra punctured and 

 pubescent like the thorax, and of the same opaque blackish-blue colour, the base near the scutellum distinctly 

 raised and convex, this convexity fitting into a corresponding concavity at the base of the thorax ; a deep 

 oblique depression is situated near the lateral margin at the middle of the elytra, a transverse short tubercle 

 is placed below the middle near the suture, and two others at the same place near the apex ; pygidium 

 fulvous, with a central blue spot, traversed through its entire length by a narrow ridge ; underside and 

 legs fulvous ; breast and centre of the abdomen dark blue ; prosternum in shape of a posteriorly narrowed 

 acute ridge. 



Eab. Costa Rica (Mus. Berol.). 



The type of this species, which has been kindly lent to me for description by 

 Dr. Peters, is a male, and is without doubt allied to C. cinerea and C. sextuberculata, 

 Jac, on account of the shape of its prosternum and the fine pubescence of the upper 

 parts. It is easily distinguished from both by the coloration and the total want of 

 any gloss, as well as by the more distinct and greater number of tubercles on its elytra.
