DESCRIPTIONS OF TWO NEW SPECIES OF THE 

 GENUS COMPHOCERA 



OLIVER E. JANSON. 



The first of the two beautiful Cetoniidae here described 

 is au exceedingly interestiug addition to our knowledge 

 of this group as being a very close ally of the Heterorrhina 

 dives Westw. ^), a species so extremely rare that, although 

 first described as long back as 1833^), the original type- 

 specimen in the Paris Museum is still, I believe, the only 

 example known, and this it has been suggested is an "arte- 

 fact" ^), made up of the body of a Coryphocera and the 

 head of a Diceros, but as the new species here described 

 has a very similar cephalic armature, I do not think any 

 reason should exist for the supposition of the type-specimen 

 of dives having been manufactured. The new species is 

 remarkable in having the head similarly armed in the 

 two sexes, which probably will be found to be the case 

 also in dives^ when the female may be discovered. My 

 description has been taken from a pair, sent by Mr. 

 Ritsema, with a request to name the species after the dis- 

 coverer. 



The other species, I have taken this opportunity of de- 

 scribing, has a quite difierent form of head, but is very 

 similar in other respects.
