abruptly recurved at apex. Middle and hind femora with scattered 

 coarse punctures each bearing a long seta. 



Male minors. — ^Length 5.2 to 7.1 mm., width 3.2 to 4.1 mm. Dif- 

 fering from male majors in the following respects: Clypeus rather 

 evenly rounded, reflexed upward only slightly more anteriorly than 

 laterally; disc evenly, rugosely punctate, the punctures bearing short 

 setae; clypeal carina more pronounced than in male majors, but of 

 uniform height and extending completely across the posterior margin 

 of the clypeus. Surface between the clypeal carina and frontal 

 carina as described for the male major; frontal carina evident through- 

 out its length, highest laterally where it forms a small knob at each 

 end; a few scattered, coarse punctm'es behind the carina; gena scarcely 

 produced. 



Pronotum with tubercles and setae as in male major, tubercles 

 almost to the anterior margin; disc generally less convex than in male 

 majors and lacldng the identations in the anterior angles ; protuberance 

 usually indicated by a slight anterior median swelling. General aspect 

 of elytra and pygidium similar to male major. Except for a slight 

 difference in punctures, the ventral surfaces resemble those described 

 for male majors. Forelegs are shortened, the apices of the anterior 

 femora extending no further than the lateral margins of the thorax, 

 the foretibia proportionately shortened, but still slender and inwardly 

 curved, the apical conical projection lacking. The middle and hind 

 legs slightly more stocky than in male majors, but otherwise similar. 



Females. — Length 5.6 to 7.6 mm., width 3.2 to 4.5 mm. Differing 

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

 rounded, slightly more reflexed anteriorly than laterally with disc 

 very coarsely, rugosely punctate, at least some of the pmictures bearing 

 reddish setae; clypeal carina extending completely across the posterior 

 margin of the clypeus, evenly elevated across middle; surface behind 

 the carma coarsely, setigerously punctate, many of the punctures with 

 small indistinct tubercles at basal edges. Frontal carina pronomiced, 

 slightly indented medially, and abruptly terminated laterally near 

 the eyes; behind it an irregular double row of setigerous punctures 

 bearing rather pronomiced tubercles at their posterior margins. 



Pronotum less convex than male majors with tubercles distributed 

 rather evenly over the enthe sm-face, the tubercles usually larger 

 and more pronounced than in males, separated generally by only 

 1 to 2 diameters; pronotal setae often less conspicuous than in males, 

 somewhat finer; protuberance indicated by a vague hump which 

 is often delimited laterally by a small shiny swelling, the distance be- 

 tween these lateral swellings approximately the same as the length of 

 of the frontal carina of the head. Elytra generally similar to those of
