492 SEEEICOENIA. 



which occurs also at Toxpam, Cordova, and Jalapa, but differs from it in the rather 

 less densely punctured thorax and elytra, and the paler and more golden pubescence of 

 the upper surface. The males are considerably smaller than the corresponding sex of 

 //. sericea, with the hind angles of the thorax a little more divergent. The elytra 

 vary in colour from brownish-black to reddish-brown, being often paler towards the 

 base ; the interstices are thickly and equally punctured throughout. In some of the 

 fresher specimens the hairs appear to be transversely combed inwards towards the 

 suture. The females are sometimes much larger, broader, and more elongate than 

 the males. If Germar has correctly identified Latreille's species, the name H. sericea 

 should be applied to this insect. 



3. Hypodesis aureipilis. (Tab. XXL fig. 22, $ .) 



Moderately elongate, broad, robust, feebly shining; reddish-brown' or castaneous, darker beneath, the legs 

 obscure testaceous or brown ; above and beneath thickly clothed with long and rather coarse golden hairs, 

 the hairs on the prothorax and on the second elytral interstice obliquely or transversely combed inwards, 

 the first four ventral segments each with a matted tuft of hairs at the sides behind. Head coarsely, 

 rugosely punctate, depressed in front; antennae extending to a little beyond the hind angles of the 

 prothorax in the male, shorter in the female, the joints from the fourth strongly serrate, 3 nearly as long 

 as 4. Prothorax convex, much broader than long, narrowed in front, the sides rounded anteriorly and 

 sinuate behind ; the hind angles long and divergent, carinate ; the surface thickly, coarsely punctate, a 

 narrow space down the middle behind and a small space on either side of the disc before the middle 

 impunctate, very distinctly canaliculate. Elytra about three and one-fourth times the length of the 

 prothorax, rapidly narrowing from a little below the base in the male, subparallel in their basal third in 

 the female ; finely punctate-striate, the punctures becoming coarse and deep towards the sides, the striae 

 deeply impressed on the basal declivity and also becoming deeper towards the apex, the interstices flat, 

 the second and fourth densely, the others distinctly more sparsely and a little more coarsely, punctate. 

 Beneath sparsely and finely, the prosternum and propleurse coarsely, punctured ; the ventral segments each 

 with a small glabrous spot at the sides. 



Length 10-11 £, breadth 3i-3§ millim. ( S 2 •) 



Hab. Panama, Bugaba (Champion), Chiriqui (Ribbe). 



Six examples. Very like H. chry Somalia, but differing from it in the unequally 

 punctured elytral interstices (the second and fourth being distinctly more densely 

 punctured than the others) and the coarsely punctured disc of the thorax ; also in the 

 shorter and more convex thorax, in the males, the sides being more rounded anteriorly 

 and less rapidly converging. The more transverse thorax and the less coarsely 

 punctured elytral striae distinguish H. aureipilis from H. punctata. 



4. Hypodesis cribricollis. 



Hypodesis cribricollis, Cand. Monogr. Elat. iv. p. 246 \ 

 Hob. Mexico (Salle l ), Jalapa (Edge). 



Four specimens of this insect have been examined, including the types; they appear 

 to be all females. H. cribricollis may be separated from H. sericea and H. chrysomalla
