It may justly be suspected that Ch. fortunata and suhcostctlis are 

 only insular forms one of the other, but maintaining their dis- 

 tinctive characters. Ch, suicostaUs is considerably more like dor-

 antennae indicated by a blackish transverse line. Palpi green, 

 slightly marked with blackish externally; the terminal joint

 Ilesonotum with a broad transverse black band in front at the 

 junction with the pronotum, somewhat dilated on each side ; all
