angles, strongly attenuate from the middle to the apex, which is con- 
jointly broadly rounded, and obsoletely serrate; humeri well devel- 
oped; each elytron with a deep, rather broad basal depression, and 
without lateral carina; surface with rows of punctures which are large 
at the base, but gradually becoming smaller toward the apex, where 
they are not very distinct, with an obsolete broken, transverse fascia 
at middle, and the entire apical third very sparsely clothed with 
rather long, recumbent, cinereous hairs; there are also a few scattered 
hairs of the same color behind the scutellum; intervals shining and 
coarsely rugose anteriorly, becoming finely and densely granulated 
at apex. Abdomen beneath moderately convex, sparsely and obso- 
letely punctate, the punctures shallow, oblong, and open on the one 
side, each puncture bearing a short, recumbent hair; intervals finely 
and densely reticulate; last segment broadly rounded at apex, with 
the apical groove broadly angulated at middle. Metasternum more 
coarsely and distinctly punctured than the abdomen. Prosternum 
finely and densely rugose. 
Length, 3 mm.; width, 1 mm. 
Type locality —Juan Mina, Canal Zone, Panama. 
Type.—Cat. No. 25121, U.S.N.M. 
Described from a single male specimen collected by J. Zetek 
February 18, 1921. This species resembles 7. attenuatus Fisher in 
form and color, but is not as strongly attenuate posteriorly, and the 
elytra is ornated with transverse pubescent fasciae. 
TAPHROCERUS UNIFORMIS Waterhouse. 
Taphrocerus uniformis WATERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 
1889, p. 130. 
This species was described from specimens collected near Mexico 
City, Mexico, and the type, which is in the British Museum, has not 
been examined. The species has been placed in the key solely upon 
the character given in the original description. 
TAPHROCERUS PURPUREIPENNIS Waterhouse. 
Taphrocerus purpureipennis WaTERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, 
pt. 1, 1889, pp. 129-130. 
This species was described from material collected on Taboga 
Island, Panama, by Mr. Champion. It is represented in the National 
Museum Collection by the following material: One specimen collected 
at Paraiso, Canal Zone, Panama, April 19, 1911, by E. A. Schwarz; 
one collected at Juan Mina, Canal Zone, Panama, February 18, 1921, 
by J. Zetek; and two other specimens collected at Finca Trece 
Aguas, Alta Vera Paz, Guatemala, at an altitude of 900 feet, March 
26 and April 15, 1906, by Barber and Schwarz. The specimens 
from Guatemala are not quite as broad as those from Panama, and 
have the head a little more deeply grooved.
