Monocrepidius probus, Cand. Elat. Nouv. iii. p. 50 \ 

 Hab. Guatemala 1 , Capetillo (Champion). 



Three specimens, agreeing with the type, communicated by Dr. Candeze. It has the 

 third joint only a little longer than the second ; and the species is best placed in his 

 second group, near nocturnus. 



18. Monocrepidius notatus. (Tab. XV. fig. 13, <s .) 



Moderately elongate, broad, rather convex, finely pubescent ; ferruginous or testaceous ; the head usually 

 infuscate ; the prothorax with a broad black or pitchy-brown median vitta, which in one specimen is 

 divided down the middle by a rufo-castaueous stripe ; the elytra with a very large, broad, common subquad- 

 rate patch at the base, an angulate post-median fascia, and an ante-apical patch (sometimes obsolete), these 

 markings connected along the suture, black or piceous, or obscure castaneous, bordered externally with 

 black ; the antennae and legs testaceous, the under surface in great part piceous or pitchy-brown. Head 

 coarsely, closely punctate, depressed in the middle in front, the frontal carina truncate and moderately 

 prominent ; antennas reaching a little beyond the base of the elytra in the female, longer in the male, joints 

 2 and 3 very short, subequal. Prothorax a little broader than long, slightly narrowed in front, convex, 

 the sides rounded from the middle forwards and feebly sinuate behind ; the hind angles greatly produced, 

 slightly divergent, sharply carinate at the sides above, and with a carina extending from the apex 

 along the basal margin of the prothorax ; the surface closely, rather coarsely punctate, and obsoletely 

 canaliculate down the middle. Elytra barely two and one-half times the length of the prothorax, 

 narrowing in both sexes from a little below the base, the apices rounded ; rather deeply punctate-striate, 

 the punctures coarse at the sides, becoming finer towards the suture ; the interstices convex at the sides 

 and apex, flatter on the disc, thickly, finely punctate. Beneath closely, uniformly punctate. Fourth 

 tarsal joint strongly lamellate beneath. 

 Length ll£-12f , breadth 3£-4| millim. ( tf 2 •) 



Hab. Panama, Bugaba (Champion). 



Var. The prothorax with a piceous stripe on either side of the broad median vitta, not extending to the 

 base or apex ; the supra-marginal carina of the hind angles not extending so far forwards, and not 

 parallel with the margin anteriorly, the margins themselves subparallel behind. ( $ .) 



Hab. Panama, Bugaba (Champion). 



Five specimens of the typical form, and one of the variety; the latter is probably
