elytris latis, valde convexis, prnnoto latioribus, plus qnam seaqui longioribus, atque 

 magis leviter et magis remote punctatis, prope media latissimis, lateribus marginatis,

Body oval, rather broad, convex, very shining, remotely punctured, deep black, 



sparingly clothed with long black hair, which is frequently abraded. 

 Head very small, ferruginous ; eyes moderate ; antennte rather large, ferruginous. 

 Thorax rather large, anterior margin broadly reilexed, translucent, moderately and 



remotely punctured, with the interstices smooth and very shining, basal margin 



slightly sinuated, with the angles right angles. 

 Scntelhnn moderate, rounded and punctured. 

 Elytra broad, very convex, broader and more than one-half longer, and more 



faintly and more remotely punctured than the thorax, widest near the middle, 



sides margined, extremities much rounded, and narrowly pale. 

 Abdomoi with the pygidium exposed, piceous. 

 Legs robust, piceous. 

 Under parts piceous, with the head, coxse, and edges of the ventral segments 



ferruginous. 

 Differs from other species in its short, broad form, deep black colour, shining 



surface, and in some specimens, by the long black hair on all parts of its body. 



Habitat, Central America. Found in Chontales, Nicaragua (.Janson), and Senahu, 

 Vera Paz (Champion). 



This very distinct species appears to be originally clothed with long black hair, 

 which often becomes wholly abraded, leaving the upper surface smooth and shining. 

 It is very variable in size, but may always be recognised by its short, broad form 

 and shining black colour.
