shining, with rather scattered shallow punctures . . 3. aequalis (Banks) 

 Fourth cubital cell with its basal 0.7 subhyahne and its apical 0.3 hghtly 

 infuscate so that the forewing has a conspicuous pale subapical spot; frons 

 mat to polished, with closer deeper punctures or not obviously punc- 

 tate 10 



10. Frons dull, with close small punctures that are difficult to see so that it may 



appear mat and impunctate; forewing with a conspicuous fuscous mark

fig. 24) 4. hcstia (Banks)

 mark over the basal vein, the mark not invading the anal cell (pi. 2, figs. 

 22, 23) 11 



11. Clypeus with a median weak transverse elevation just before the apex that 



gives the impression of a weak flattening just beyond the elevation; frons 

 more densely punctate; frons and pleura more strongly mat; forewing 6 to 9
