clivity; each puncture with a small tubercle in front of the seta, the 

 tubercles disappearing laterally and posteriorly and the punctures 

 becoming much coarser and farther apart, with a few fine punctures 

 intermixed, the surface otherwise smooth and shining. Elytral striae 

 vaguely punctate, intervals smooth and shiny and, except for the su- 

 tiu-al one, each with a double row of minute tubercles having setigerous 

 pmictm-es at their bases. Pygidium feebly convex, with scattered, 

 coarse, setigerous punctiu-es, the punctures becoming smaller apically; 

 surface between the punctures finely alutaceous basally, apically al- 

 most smooth. 



Ventral surfaces and legs reddish brown to black. Antennae 

 reddish brown, the club slightly lighter in color. Proepisternum only 

 slightly excavated to receive antennae. Mesothorax and lateral areas 

 of prothorax and metathorax coarsely setigerously punctate and finely 

 alutaceous. Median area of metathorax smooth and shiny, with 

 scattered nonsetigerous punctures, often with a vague sulcus along 

 the median line. Abdomen except for fu'st segment with a basal row 

 of minute setigerous punctures extending across each segment, last 

 segment narrowed medially. Forelegs approximately the same length 

 as those of female, tibia stoutly and conspicuously quadridentate ; 

 outer margin smooth between the teeth, occasionally vaguely serrate 

 above them; conical projection lacking above apical spine. Femora 

 of all legs with numerous setae in an irregular row at their anterior 

 and posterior edges, the flattened ventral surface with scattered 

 coarse setigerous punctures. 



Male minors. — Length 4.7 to 6. mm., width 2.7 to 3.7 mm. Very 

 similar to male majors. Anterior clypeal margin slightly less re- 

 flexed but of approximately the same shape; clypeal carina and frontal 

 carina less pronounced than in male majors but of the same con- 

 figuration. Pronotum considerably less convex with pronotal pro- 

 tuberance scarcely evident, disc often with minute scattered punctm*es. 

 Except for slightly more pronounced punctm^es and setae on elytra 

 and other parts of body, the male minors do not differ conspicuously 

 from the male majors. 



Females. — Length 5.5 to 6.4 mm., width 3.0 to 3.6 mm. Very 

 similar to male minors, the major difference being in the slightly more 

 elongate shape of pygidium and in the last abdominal segment which 

 is not narrowed medially. Little indication of a pronotal protuber- 

 ance; the punctures and setae usually more in evidence than in the 

 male. Little apparent difference in other aspects (carinae, legs, etc.) 

 between the male minors and the females. 



Type. — Lectotype, present designation, USNM 1300, a female 

 specimen collected at Crescent City, Fla., July 15 by H. G. Hubbard; 

 deposited in USNM in 1896 as type.
