from anterior angles of liead; surface of anterior part of liead 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. 

 Priraary scars 1 ) on mentum present, secondary scars 1 ) not extending to 

 posterior margin. Anterior intermediate and lateral areas of metasternnm 

 fused. Type, K. trigonophorus (ZANG 1905, p. 316). Only one species 

 of this genns is yet known. 



Kaupsoloides trigonophorus (Zang). 



Eedescribed from fonr specimens from New Guinea, in the collection 

 of the Deutsches Entomologisches Museum. Two of the 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

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 distinct one from another on both sides. The mentum bears 

 a row of hair-bearing punctnres along its posterior margin; otherwise it 

 is unpunctnred between the primary scars, and pimctnred as usual laterally. 

 The form of the anterior margin of the head has already been described 

 in the definition of the genns; its surface is somewhat rugose, that of all 

 the rest of the head being smooth, with or without a few broad punctures 



') Concerning- the distinction between priraary and secondary scars, and the other 

 terms applied here to different parts, see GRAVELY, 1913 (pt. II).
