large oval spot on sides and narrow posterior border of pronotum, 

 tegulae, lateral posterior spot on mesoscutum above tegulae, superior

 broad apical bands on tergites one to five inclusive, incised laterally 

 on tergites three, four, and five, interrupted preapical band on sixth 

 tergite, interrupted apical band on second, complete on third and 

 fourth and four apical spots on fifth sternites; the following parts 

 burnt sienna : mandibles, antennal club beneath and legs below coxae ; 

 following parts piceous : flagellum except where mentioned and apical 

 margin of sixth sternite ; wings slightly smoky, the costa castaneous, 

 the other veins dark brown ; hair of head and thorax blackish. 



Front dull, with large separate punctures which are much closer 

 medially; clypeus finely punctulate with a few large punctures dor- 

 sally. Humeri rounded ; pronotum with separated punctures ; mesono- 

 tum with large, sometimes confluent punctures which are closer and 

 finer in the flattened posterior part ; scutellum with large, distinct 

 punctures laterally and with a rather narrow granular area medianly ;

"J*. Length about 12 mm. Very like tcxanus (Cresson), from 

 which it may be separated by the following characters: very few 

 large punctures on the front and these not sharply defined ; posterior 

 part of mesoscutum uniformly punctured (in texanus the depressed 

 area is more closely punctured) ; punctuation of abdomen finer; second 

 dorsal segment depressed by fully half of its entire length (in texanus 

 it is hardly depressed) ; third segment hardly depressed (in texanus 

 it is depressed by fully one-third) ; punctures of the apical dorsal seg- 

 ment more widely separated ; second cubital cell on the radius longer, 

 being in the type greater than the distance between the recurrent 

 veins (in texanus it is much less) ; markings whitish; clypeus except 

 apical part pale ; wings slightly yellowish in stigmal area, otherwise 

 hyaline. ' '
