Tliis is the most splendidly ornamented Prosojtis known to 

 me ; whether it is strictly of that genus may be doubted, but 

 1 have not been able to see the mouth-[)arts. It is very easily 

 recognized by its peculiar markings.

Bomhus tetrachromiiSj sp. n. 



$. — Size o^ B. riifo/asciatusj Sm., which it resembles in 

 pubescence of head and thorax, but in the abdom^'u it is 

 quite different, inasmuch as the hair of the basal part, before 

 the red band, which is black in rufofasciatus, is bright 

 canary-yellow. The sides of the first segment have long 

 white hair, as in rufo/asciatus. As in ru/o/asciutue, the 

 median band on tiie abdomen is bright red and tlie ajiical part 

 is white. Superficially this is so exactly a rufofasciatus with 

 yellow in place of black on the abdomen, that I thought it 

 might be merely a remarkable variety, but the following 

 structural differences show that this cannot be: — 



Malar space about as long as broad ; fourth antennal 



joint longer tliuu wide rufofasciatus, Sm, 



Malar space much shoiter; fourth antennal joint 



shorter, rather wider than loujj telrachromus, CklL
