LIUS PARVULUS, var. Waterhouse. 
Iius parvulus, var. WATERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 
1889, p. 136-137. 
This variety with the head and pronotum cupreous or cupreo- 
aeneous, is recorded by Waterhouse as occurring with the typical 
form at Bugaba, Panama, and also from Zapote, Guatemala, but 
without giving it any varietal name. It differs only slightly from 
the descripton given for Lius amabilis, described by Kerremans from 
Mexico, and it is just possible that two forms are identical. It is 
represented in the National Museum Collection by the following ma- 
terial: Five specimens collected at Paraiso, Canal Zone, Panama, 
between January 16 and March 18, 1911, by E. A. Schwarz; two 
others from the same locality collected April 10, 1911, by A. H. 
Jennings; and another specimen collected at Finca Trece Aguas, 
Alta Vera Paz, Guatemala, at an altitude of 900 feet, March 30, 1906, 
by Messrs. Barber and Schwarz. 
LIUS VARIABILIS Waterhouse. 
Lius variabilis WatERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 1889, 
p. 136. 
This species was deseribed from material collected by Mr. Champion 
at Chiacam, San Joaquin, and San Geronimo, Guatemala, without 
designating any definite type locality. It is represented in the 
National Museum Collection by a single specimen, which may be 
one of the paratypes, received from F. D. Godman and labeled “S. 
Gerénimo, 3000 ft. Champion.” This species is longer in proportion 
to its width than any of the other species examined, and is more 
regularly convex. The color is quite variable, and the specimen in 
the National Collection has the head, pronotum, and scutellum aene- 
ous, and the elytra of a purplish-coppery color, with a slight greenish 
tinge on the disk. 
LIUS AMABILIS Kerremans. 
Lius amabilis Kerremans, Ann, Soc. Ent. Belg., vol. 40, 1896, pp. 329-330. 
Described from material collected in the refuse of tobacco imported 
into Paris, France, from Mexico. The origin of the specimens col- 
lected under these conditions should be verified, as tobacco from 
Brazil and other localities was stored in the same building. It is 
placed in the key solely upon the characters given in the original 
description. From the description given it is closely allied to the 
variety of parvulus with the cupreous pronotum, recorded by Water- 
house from Panama and Guatemala. 
Genus TAPHROCERUS Solier. 
Taphrocerus Sourer, Ann. Soc. Ent. France, ser. 1, vol. 2, 1833, pp. 314-315. 
The species of this genus are elongate and agriliform, and their 
distribution is confined to the Western Hemisphere. The genus con-
