Family TIPHIID^. 



Genus TIPHIA Fabricius. 



The following three species of TipTiia do not agree with the descrip- 

 tions of any of the described species. The species of this genus, 

 although as a rule possessing good characters, have in America not 

 been described with sufficient accuracy to make their determination 

 certain.

Female. — Length 10.5 mm. Clypeus rounded anteriorly, not 

 dentate; nasal margin of the eyes diverging to the clypeus; head with 

 large, distinct, rather close punctures which are closer on the front; 

 a glabrous streak from anterior ocellus; postocellar line distinctly 

 shorter than the ocellocular line; ocelloccipital line and ocellocular 

 line of approximately the same length; third antennal joint slightly 

 shorter than the fourth, apical joint slightly tapering much longer
