Forefemiir and tibia not greatly elongate, the tibia lacking the apical 

 conical tooth over the tibial spine, the spine however being still rather 

 short and stubby; the four lateral tibial teeth intermediate in size 

 between those of the male major and the female. 



Females. — Length 6 to 6.5 mm., width 3.5 to 4 mm. Differing 

 from the male major in the following respects: Clypeus rather evenly 

 arcuate, scarcely emarginate, only sligthly reflexed anteriorly and 

 laterally; disc very coarsely rugosely punctured, much more so than 

 in males; carinae of both clypeus and vertex pronounced, that of the 

 latter usually being slightly more pronounced and highest at the center, 

 occasionally vaguely indented medially; frons before the carina more 

 densely punctured than in male majors, the punctures being separated 

 by onl}' slightly more than their own diameters. 



Pronotum similar to male minor with the pronotal process evidenced 

 by a broad hump extending no farther than the anterior pronotal 

 margin. Punctures of the elytra more pronounced than in the major- 

 ity of males, those of the second and fom"th intervals being small, 

 often obsolete; punctures of pygidium more numerous than in males. 

 Prothoracic legs not elongate, the apical end of the femm* not extending 

 as far as the lateral margin of the thorax and the tibia proportionately 

 shortened; apical tibial spine long, curved inward near the tip, and 

 lacking the basally overhanging conical projection; laterally the outer 

 margin of the foretibia is serrate between and above the fom* large 

 teeth. Mesothoracic and metathoracic femora slightly thicker and 

 shorter than in male majors.
