296 AMERICAN PACHYBRACHYS (cOLEOPTERa) 



1825. Say — Amer, Ent., II, PI. 28 — othonus; common, and 



familiar to all collectors. 

 1838. Randall — Boston Jour. Nat. Hist., II, p. 46 — describes 



marginaticollis. A synonym of othonus Say. 



1840. Newman — Mag. Nat. Hist., IV, p. 250 — describes limba- 

 tus. This name is preoccupied by Menetries (1836) for a 

 species from Asia Minor; discoideus Bowditch (1909) replaces 

 it. 



1841. Newman — Entomologist, p. 78 — describes sparsiis which 

 has been declared to be the same as femoratus Oliv. 



1843. Mannerheim — Bull. Mosc, II, p. 311 — describes sig- 

 iiatijrons. The first species from the Pacific coast to receive 

 a name. 



1847. Melsheimer— Proc. Acad. Nat. Sci. Phila., Ill, pp. 170- 

 172 — describes in the following order — m-nigrum, atomarius, 

 trinotatus, aesculi, pectoralis, hepaticus, tridens, flavicornis. 

 Of these, aesculi and flavicornis are slight varieties of luridus 

 and tridens respectively. The others are all more or less 

 common in the North Atlantic Coast region, though atoma- 

 rius and pectoralis are usually wrongly identified in collec- 

 tions. 



1849. Haldeman — Jour. Acad. Nat. Sci. Phila., 2d Series, I, pp. 

 257-263 — describes punctatus (^hepaticus Melsh.), morosus 

 ( = pubescens Oliv.), carhonarius, infaustus ( = atomarius 

 Melsh.), sohrinus and mollis { = tridens Melsh.). 



1853. Suffrian — Linn. Ent., VII — describes a large number of 

 species from the United States, Mexico and the West Indies. 

 Many of these have remained unknown to American stu- 

 dents, but the recent loan to Mr. Bowditch and myself of 

 certain types from the Suffrian collection has enabled us to 

 clear up much of this uncertainty. I give below in the order 

 of their description the species occurring (so far as known) 

 in our fauna, with some notes as to our present knowledge 

 of them. 

 haematodes. Described from Mexico, but known to us from 



the states along the Mexican border. 

 pulvinatus. Identified with certainty from a type sent by 



Dr. Taschenberg of Halle. 

 varicolor. Determined by comparison with specimens sent
