132 Mr. G. C. Champion’s Notes on 
Centr.-Am., Coleopt. 1, 2, p. 199 (1883); Fall, Trans. 
Am. Ent. Soc. xxxi, pp. 154, 171 (1905) ; Pic, Ann. Soe. 
Ent. Belg. xlvi, p. 408 (1902), and Cat. Anobiidae, 
p. 30 (1912). 
Gorham enumerated four species of this genus from 
Central America, eight are recorded by Fall from the 
United States or Lower California, and various others 
have been described by Pic from Mexico or 8. America. 
T. imperator, Cast., from Mexico, was, as stated by Pic, 
wrongly identified by Gorham, and the examples from the 
Mexican and Guatemalan localities quoted by him belong 
to various different species. These are described below, 
and some notes on the other Mexican forms are also 
appended. The thirteen species now known from Mexico 
and Central America may be tabulated thus :—

at the sides behind.
