H. C. FALL 295 



As there is obviously no doubt as to what Chevrolat's name was 

 intended to cover, I shall cite him as authority for the genus, and 

 I shall spell the name correctly.^ This seems to me the common 

 sense of the matter, and the conclusion is to me all the more 

 satisfactory since it coincides with the views of Dr. LeConte, 

 and recjuires no deviation from American custom. 



Chronology 



Chronologically our species have been described as follows: 



1798. Fabricius — Suppl. Ent. Syst., p. 109. Here appears 

 luridus, the first of our species to receive a name. A com- 

 mon species, known to all collectors. 



1801. Fabricius — Syst. Eleuth., II, p. 49 — makes known 

 viduatus from "Carolina" in a very brief description of ten 

 words. The species is confined to the Southeastern states 

 and is not overly common in collections. Until recently 

 the name viduatus has been commonly and erroneously 

 applied to the hivittatus of Say. 



1808. Olivier — Entomologie, VI, p. 810, 820 — describes femora- 

 tus and puhescens. The former is one of the numerous 

 mottled species, and the description is insufficient for posi- 

 tive identification. I have followed LeConte's interpreta- 

 tion, which I believe to be correct. Puhescens is a well 

 known species which has been more often alluded to under 

 Haldeman's name morosa. 



1824. Say— Jour. Acad. Nat. Sci. Phila., III. pp. 436-440— 

 describes abdominalis, hivittatus, nigricornis and Jemoratus. 

 The last named is a synonym of luridus Fab. Hivittatus 

 is a well known species which has passed as viduatus Fab. 

 LeConte seems to have properly identified ahdominalis, 

 but both this and nigricornis have remained unknown to 

 most American entomologists. 



1824. LeConte (Major)— Ann. Lye. Nat. Hist. N. Y., I, p. 173— 

 describes subfasciatus. A well known species. 



1824. Germar— Ins. Sp., p. 560— describes picturatus. Our 

 interpretation of this species is not entirely certain; it is of 

 rare occurrence.
