from anterior angles of head; surface of anterior part of head level, 
without any trace of deep excavations on either side. Antennae with 
six well developed lamellae none of which are very long or slender. 
Dentition normal, complete and well-developed on both mandibles. 
Primary scars') on mentum present, secondary scars'!) not extending to 
posterior margin. Anterior intermediate and lateral areas of metasternum 
fused. Type, K. trigonophorus (ZANG 1905, p. 316). Only one species 
of this genus is yet known. 
Kaupioloides trigonophorus (Zang). 
Redescribed from four specimens from New Guinea, in the colleetion 
of the Deutsches Entomologisches Museum. Two of tlıe specimens 
(including the type) are from the Toricelli Mountains in Kaiser-Wilhelms- 
Land, one is from Sattelberg, and one probably from Humboldt Bay. 
Length 32—34 mm. The anterior margin of the labrum is straight 
or slightly concave; the sides are slightly convex; the angles are rounded, 
that of the left side being often somewhat more acute than that of the 
Fig. 1.

right. The upper tooth of both mandibles is more or less obsolete; the 
three terminal teeth and anterior lower tooth are conical, well-developed 
and perfectly distinet one from another on both sides. The mentum bears 
a row of hair-bearing punctures along its posterior margin; otherwise it 
is unpunctured between the primary scars, and punctured as-usual laterally. 
The form of the anterior margin of the head has already been described 
in the definition of the genus; its surface is somewhat rugose, that of all 
the rest of the head being smooth, with or without a few broad punctures 
!) Ooncerning the distinetion between primary and secondary scars, and the other 
terms applied here to different parts, see GRAVELY, 1913 (pt. ID.
