TAPHRCCERUS PSILOPTEROIDES Waterhouse. 
Taphrocerus psilopteroides WATERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, 
pt. 1, 1889, p. 129. 
This species was described from Chiacam, Guatemala, and the type 
is in the British Museum. It has been reported also from Mexico 
and Panama by Waterhouse, and is represented in the National 
Museum Collection by three examples; one collected at Paraiso, 
Canal Zone, Panama, January 26, 1911, by E. A. Schwarz; one col- 
lected at La Ceiba, Honduras, August 15, 1916, by F. J. Dyer; and 
another specimen swept from grass and cowpeas at Juan Mina plan- 
tation, Canal Zone, Panama, July 13, 1918, by H. F. Dietz and J. 
Zetek. 
TAPHROCERUS SULCIFRONS, new species. 
Male.-—Hlongate, attenuate posteriorly, subcylindrical, ‘uniformly 
brownish, with a strong aeneous tinge, and with pubescent spots 
above; beneath of the same color as above. 
Head nearly as wide as pronotum at base, feebly convex and 
broadly flattened behind the epistoma, causing two feeble, smooth 
gibbosities on the front, with a longitudinal groove extending from the 
occiput to near the epistoma, the groove obsolete on the occiput, but 
becoming deeper on the vertex and front; surface sparsely, irregularly, 
and coarsely punctate, the punctures very shallow and obsolete on 
the occiput, and much finer and denser on the flattened area behind 
the epistoma, sparsely clothed with short, inconspicuous hairs, except 
along the epistoma, where the pubescence is longer and much denser; 
intervals finely and densely granulated. Pronotum moderately con- 
vex, one and two-thirds times as wide as long, slightly narrower in 
front than behind, widest at the base; sides when viewed from above 
feebly, obliquely dilated to the posterior angles, which are rather 
obtuse; anterior margin truncate; base transversely truncate to 
middle of elytron, then turning obliquely backward to the scutellum, 
in front of which it is feebly, arcuately emarginate; surface with a 
broad obsolete depression along the anterior margin, and a more 
narrow, obsolete one along the sides, broadly concave in front of 
scutellum, the concavity extending on each side into a deep depres- 
sion, which is prolonged obliquely toward the anterior angles, these 
depressions cause the surface to be broadly gibbose on the median 
anterior part, and a small gibbosity on each side near the posterior 
angles, sparsely, irregularly punctate, the punctures very shallow 
and somewhat denser in the depressions, sparsely clothed with short, 
recumbent, cinereous hairs; intervals finely and densely granulated. 
Scutellum triangular, obsoletely reticulate, feebly rounded in front. 
Elytra rather strongly convex, slightly narrower than pronotum at 
base; humeral angles rather obtusely angulated; sides rather strongly 
sinuate behind the humeri, as wide at the middle as at the humeral
