clypeus prolonged anteriorly, usually evenly rounded, occasionally 

 sharply emarginate. Other features of head as described for s. striat- 

 ulus. Pronotum with margins, angles, and protuberance as de- 

 scribed for s. striatulus; punctures shallow and poorly defined, ante- 

 rior margin of each punctui'e with a pronounced tubercle which bears 

 a short whitish (not usually blackish as stated by Blatchley, 1916, 

 p. 94) seta at its base, often appearing more tuberculate than punctate. 

 Elytra as described for s. striatulus except that the surface of the in- 

 tervals between the tubercles is smooth and shiny, not alutaceous as 

 in s. striatulus; tubercles of the intervals in two or three irregular rows, 

 each tubercle with a short white seta at its base. Pygidium and 

 ventral surfaces black and shining with morphological characteristics 

 falling within the limits described for s. striatulus. 



Male minors. — Length 5.5 to 5.9, width 3.3 to 3.5 mm. Seemingly 

 infrequent in the population. Color black, shining, rarely vaguely 

 greenish. Pronotal tubercles pronounced with whitish setae more 

 evident than in male majors. Elytral intervals still smooth between 

 the two or three rows of tubercles. In other features (carinae of head, 

 pronotal modifications, length of fore tibia, etc.) male minors of s. 

 floridanus resemble those of s. striatulus. 



Females. — Length 6.8 to 7.2 mm., width 3.8 to 4.2 mm. Dorsal 

 color shining black, occasionally faintly greenish. Pronotal tubercles 

 more pronounced than in males, punctures shallow. Setae on pro- 

 notum, elytral intervals, and ventral sm'faces whitish and conspicuous. 

 Elytral intervals between the two or three rows of tubercles smooth 

 and shining. In other respects females of s. floridanus resemble those 

 of s. striatulus. 



Type. — Purdue University, Lafayette, Ind. 



Type locality. — Dunedin, Fla. 



Specimens examined. — ^107. 



Distribution. — (See fig. 1, p. 17.) 



Georgia: Alma (Bacon Co.). Florida: Bartow, Crescent City, Dunedin, 

 Gainesville, High Springs (Columbia Co.), Lutz, Miami, south Carolina: 

 Aiken, Bulls Island, Goose Creek (Berkeley Co.), Hampton, Longs (Waccamaw 

 River), Marion, Meredith, Summerville. (Fifteen additional specimens from 

 Dunedin, High Springs, and Gainesville, Fla., and from Florence, Longs, Mere- 

 dith, and Scranton, S.C., show varied amounts of faint alutaceous sculpture on 

 the elytra. These should perhaps be considered intermediate forms.) 



Remarks. — The subspecies 0. striatulus floridanus Blatchley is 

 largely confined to peninsular Florida and the Atlantic Coast north- 

 ward to Myrtle Beach, S.C. Blatchley took his type specimen, a 

 male, at Dunedin, Fla., on Nov. 1 from a "decaying flesh}^ fungus." 

 He stated that the pronotal setae were blackish and the elytral setae 

 very fine. In specimens taken by F. N. Young at Miami and in
