MEGAPENTHES. 381 



Hab. Mexico, Jalapa (H'6ge\ Yucatan [Pilate, in coll. Janson). 



Two female specimens. The Yucatan example, which is in a mutilated condition, 

 differs from the one from Jalapa in its ferruginous colour, and in having the elytral 

 interstices more distinctly granulate ; it is labelled Steatoderus rufus, Pilate. M. mexi- 

 canus is a near ally of M. bicarinatus, but may be known from it by the less coarsely 

 punctured thorax, the interspaces between the punctures smooth and shining, the 

 elytra more parallel, more shining, and with coarser sculpture. This is one of several 

 closely allied species of which very few examples are available for examination. 



8. Megapenthes sobrinus. 



Moderately elongate, feebly convex, rather dull, pubescent ; the head obscure ferruginous, the prothorax 

 piceous or pitchy-brown, with the base and hind angles broadly flavo-testaceous and the apex ferruginous, 

 the elytra brown, with the base on either side of the scutellum more dilute in colour ; the under surface 

 ferruginous ; the legs and antennae testaceous. Head moderately convex, closely, somewhat coarsely 

 punctate ; antennae rather slender, in the male about half the length of the body, in the female only 

 reaching the hind angles of the prothorax, joint 3 a little longer than 2, the two together not longer 

 than 4. Prothorax longer than broad, narrowing from the base forwards in both sexes ; the hind angles 

 acute, divergent, finely unicarinate ; the surface closely and rather coarsely punctured, with the narrow 

 interspaces dull, obsoletely canaliculate behind. Elytra moderately long, gradually narrowing from the 

 base, rounded at the apex ; deeply and somewhat coarsely punctate-striate, the interstices slightly convex, 

 thickly punctate, and subgranulate. Eeneath thickly punctured ; posterior coxal plates broadly and 

 angularly widened opposite the point of insertion of the femora. 



Length 6-6f , breadth li-l| millim. ( <5 $ •) 



Hab. Panama, Bugaba [Champion). 



Two males and one female. This insect somewhat resembles M. opaculus, Cand., 

 from Cuba; but it is much smaller and less elongate, the third joint of the antennae is 

 very little longer than the second (it is as long as the fourth in M. ojoaculus), &c. The 

 insect is unknown to Dr. Candeze. 



9. Megapenthes asperatus. 



Moderately elongate, feebly convex, dull, thickly pubescent ; the head black, ferruginous in front, the 

 prothorax black, with the base broadly and the apex narrowly testaceous, the elytra pitchy-brown ; the 

 under surface in great part piceous ; the antennas ferruginous, the legs testaceous. Head convex, closely, 

 rather coarsely punctate ; antennas ( $ ) short, about reaching the hind angles of the prothorax, joint 3 

 a little longer than 2, the two together scarcely longer than 4. Prothorax longer than broad, very 

 gradually narrowing from a little before the base to the apex, the sides slightly rounded in front ; the hind 

 angles acute, not divergent, unicarinate ; the surface closely impressed with very shallow, umbilicate 

 punctures, the narrow interspaces opaque, feebly canaliculate behind. Elytra moderately long, gradually 

 narrowing from about the basal third, conjointly rounded at the apex ; deeply and rather finely punctate- 

 striate, the interstices feebly convex, roughly punctured and subgranulate. Beneath closely punctured ; 

 posterior coxal plates strongly and angularly widened opposite the point of insertion of the femora. 



Length 6^, breadth If millim. ( $ .) 



Hab. Guatemala, Teleman in Vera Paz (Champion). 



One female example. Closely allied to M. sobrinus, from the same sex of which
