front, the crenations slightly wider on the terminal segment. Pygidi- 

 um shining, smooth at apex, scabrous along transverse limiting carina, 

 a few scattered setigerous punctures over disc. Anterior femur without 

 mai^nal groove, posterior face smooth and shining. Posterior femur 

 one-third wider than middle femur, smooth, shining, no posterior 

 marginal line, a row of close, coarse setigerous punctures parallel to 

 but at some distance from the posterior edge. Middle and posterior 

 tibiae without transverse ridges, with longitudinal rows of tubercles. 

 Outer edge of posterior tibia twice as long as width of apex, spurs 

 sharp, narrowly foliacious, the longer subequal to combined length of 

 first two tarsal joints. Tarsus four-fifths as long as outer edge of tibia, 

 the first joint more than twice as long as its apical width and subequal 

 to following three joints combined. Length 3.4 to 4.6 mm., width 

 1.6 to 2.1 mm. 

 Type: Location unknown to me. 



Type locality: Harold's description of Psammodius cruentus 

 appeared without locality data in his paper on "Die Chilensischen 

 Aphodiden." The type locality, therefore, would be expected to be 

 in Chile. The fact that the species has been taken over much of 

 northern Argentina and in Bolivia and that at the time Harold wrote 

 his paper part of present day Argentina was claimed by Chile would 

 indicate Argentina may more likely have been the source of his speci- 

 mens. I have seen no specimens from Chile. 



Psammodius shermani Cartwright was described from Sullivans 

 Island, S. C.

Season: October to April in South America, June 3 to Sept. 10 in 

 North America. 



Remarks: I have been unable to study type specimens of Psam- 

 modius cruentus Harold; however, specimens from South America 

 and from museums in London and Munich determined as this species 

 are all identical and agree with the original description. The earliest 

 date I have seen on specimens from North America is that on a 

 specimen collected at Tybee Island, Ga., June 1927, by H. A. Wenzel,
