TAPHROCERUS GUTTATUS Waterhouse. 
Taphrocerus guttatus WATERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 
1889, p. 129. 
This species was described from San Juan in Vera Paz, Guatemala, 
and the type, which is in the British Museum, has not been exam- 
ined. This species has also been reported from Panama, and is rep- 
resented in the National Museum Collection by a single example 
collected at Livingston, Guatemala, May 11, 1906, by Barber and 
Schwarz. 
TAPHROCERUS MEXICANUS Waterhouse. 
Taphrocerus mexicanus WATERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 
1889, pp. 128-129. 
This species was described from material collected in a number of 
localities in Mexico and Guatemala, without giving any definite 
type locality. The type is in the British Museum and has not been 
examined. There is only one specimen in the National Museum 
Collection which would apply to this species, but for the present is 
retained under the following species, which is probably a synonym. 
TAPHROCERUS LEONI Duges, 
Taphrocerus leoni Ducks, La Naturaleza, ser. 2, vol. 2, 1891, p. 35, pl. 2, fig. 61, 
6la. 
This species was described from Tupataro, State of Guanajuato, 
Mexico, and the location of the type is unknown to the writer. There 
is a specimen in the National Museum Collection, which was received 
for determination from Eugenio Dugés a number of years previous 
to the publication of his description of Taphrocerus leoni, and labeled 
in his own handwriting, ‘‘No. 562, Brachys albosignatus H. Dug.,”’ 
without any locality given. This is probably a manuscript name of 
Dugés, and no published description of it can be found. This speci- 
men probably was taken from a set, from which he described this 
species a few years later. Waterhouse described his Yaphrocerus 
mexicanus from a series of specimens, including material from Sallé, 
which is from the same locality as leoni described by Dugés. In 
carefully comparing the descriptions, I can not find sufficient char- 
acters for separating the two species, and probably Taphrocerus leon 
Dugés is a synonym of Taphrocerus mexicanus Waterhouse. 
A specimen received from Prof. H. F. Wickham, which was col- 
lected by himself at Tepehuanes, Durango, Mexico, differs slightly 
from the specimen from Tupataro by being slightly more slender and 
brassy, the pubescent spots not quite as distinct, but the brassy 
punctured areas are present, which indicates that the surface has 
been denuded of some of the pubescence.
