« 8 . Pubescence of the upper surface coppery-orange ; prothorax 



and elytra densely punctured sericea. 



b b . Pubescence of the upper surface golden ; prothorax and elytra 

 more sparsely punctured. 



a 7 . Elytral interstices uniformly punctured chrysomalla. 



b 7 . Second and fourth elytral interstices more densely punctured 

 than the others ; prothorax shortei', and more coarsely 



punctured on the disc aureipilis. 



b\ Prothorax coarsely, rugosely punctate, obsoletely canaliculate . cribricollis. 

 b*. Elytra coarsely punctate-striate, the striae shallow (obsolete in 



some specimens) ; prothorax canaliculate punctata. 



b'". Prothorax with a distinct projecting tuft of hairs in the centre at the 



base, canaliculate, and sparsely punctate penicillata. 



b". Elytra almost glabrous, submetallic (except in var. /3) ; prothorax with 



a projecting tuft of hairs in the centre at the base, canaliculate . . auricoma. 

 b'. Hind angles of the prothorax without distinct carina; elytra vittate . . vittata. 

 b. Ventral segments with a large smooth glabrous space on either side; pro- 

 thorax without distinct median groove, the hind angles carinate ; elytra 

 metallic viridipennis.

In this insect, of which upwards of a dozen examples are before me, the pubescence 

 of the upper surface is of a uniform coppery-orange colour and that of the lower 

 surface cinereous, the hairs on each of the first four abdominal segments (as in 

 II . chrysomalla, H. cribricollis, &c.) forming a matted tuft at the sides behind, this 

 being partly visible from above. The abdominal segments have each a small glabrous 

 spot at the sides. 



2. Hypodesis chrysomalla.

 Hypodesis chrysomalla, Cand. Monogr. Elat. iv. p. 244 2 . 



Hab. Mexico 1 , Toxpam, Cordova, Orizaba (Salle 2 ), Eortin in Vera Cruz (H. H. 

 Smith), Jalapa. Tapachula (Hoge) ; Guatemala, Coban (Conradt), San Juan in Vera 

 Paz, Zapote (Champion). 



Sent in plenty from Jalapa. The three specimens from San Juan (abraded females) 

 have the thorax less closely punctured than usual, but they appear to belong here 

 rather than to H. penicillata. H. chrysomalla is probably a variety of H. sericea,
