THE CANADIAN ENTOMOLOGIST 141 



Dermestes elongatus Lee. A single specimen was taken 

 from beneath the carcass of a gopher turtle on March 8. LeConte 

 described it from Georgia as rare, and Schwarz records one speci- 

 men from Haulover, Florida. 



Moncedus guttatus Lee. Taken in numbers Feb. 23 — 29, and 

 again December 13, by beating masses of a very slender milkweed, 

 Metastelma scopanum Nutt., near the border of a wet hammock. 

 Horn in 1882* characterized the genus Moncedus, placing it in the 

 family Lathridida:', and described M. guttatus (crediting the species 

 in a footnote to Dr. LeConte) from "a single specimen taken by 

 H. G. Hubbard at Cedar Keys, Fla."** 



In 1894 Sharp erected the family AdimeridcB for a supposed 

 new genus, Adimeriis, of which he described three species from 

 Central America. f Arrow in 1909 states! that Adimeriis Sharp 

 (1894) is a synonym of Moncedus Horn (1882), and corrects Horn's 

 mistake regarding the number of tarsal joints. He retained the 

 family name AdimeridcB and listed five species of Monoedtis. In 

 1913 Champion + + accepted Arrow's conclusions regarding the 

 synonymy of Adimeriis and placed M. dubius Sharp as a synonym 

 of M. guttatus, but still retained the family name proposed by Sharp. 



In conformity with Article 5 of the International Rules of 

 Zoological Nomenclature the family name AdimeridcB Sharp should 

 be abandoned, being based on a generic name which was a synonym, 

 and should be replaced by Moncedidce, with Moncedus Horn as the 

 typical genus. ^ The genus is represented in Guadeloupe and 

 Central America by sev^eral species which are said to occur under 

 bark. M. guttatus is represented in the U. S. National Museum 

 collection by three specimens from Florida, all taken by Hubbard 

 and Schwarz at Biscayne on May 10; also by specimens from 

 Tampico, Panama, Cuba, Guatemala and Monteserrat.^

**Mr. H. S. Barber, in a recent letter, states that Mr. Schwarz "avers that 

 guttatus was not taken by either Hubbard or himself at Cedar Keys, but that 

 the type specimen came from Jupiter, Fla."

1 Since this was in type Mr. Barber has called my attention to the fact 

 that Leng and Mutchler (Bull. Am. Mus. Nat. Hist., vol. 33, p. 415) have used 

 the family name Moncedidce for four species of Moncedus from Guadeloupe.
