Tricentrus pilinervosus Funkh., Journ. Ent. & Zool. (1914), 6, 68, 

 figs. 2 and 2a. 



A black, stout species with rather widespreading, elevated 

 suprahumeral horns. Near T. decoratus Dist., but differing 

 particularly in the shape and position of the posterior process. 

 Veins of tegmina very hairy. 



Black, densely and coarsely punctate, sparsely pilose. Supra- 

 humeral horns extending upward, outward, and slightly back- 

 ward, as seen from above rounded before and almost straight 

 behind. Posterior process narrow, acute, carinate, extending 

 beyond internal angle of tegmina. Tegmina fuscous hyaline, 

 base black and punctate, costal and apical margin clouded ; veins 

 each bearing two rows of short bristly hairs. Undersurface of 

 body black. Legs dark ferruginous. 



Length, including tegmina, 6 to 7 mm. ; width between extrem- 

 ities of horns, 3.5 to 4 mm.

Tricentrus plicatus sp. nov. Plate II, fig. 12, a and b. 



Near T. fairmairei Stal, but larger and different in color, in 

 the form of the posterior process, the wrinkled condition of the 

 tegmina, and the shape and position of the suprahumeral horns. 



Black, punctured, pubescent; pronotum convex, lateral angles 

 prominent, suprahumeral horns very slender, posterior process 

 gradually acuminate, extending beyond internal angle of teg- 

 mina ; tegmina smoky hyaline, much wrinkled, black and punctate 

 at base. 



Head wider than long, black, finely punctate, very densely 

 pilose with yellow hairs; eyes large, reddish brown, extending 

 beyond lateral margin of pronotum at base of head ; ocelli opaque 

 brown, almost equidistant from each other and from the eyes 

 and situated slightly above a line passing through center of eyes ; 

 clypeus extending for half its length below the line of the face, 

 sharply emarginate at base, lower margin slightly turned out at 

 edge. Pronotum moderately convex, almost perpendicular above 

 head, rounded between horns, black, finely and densely punctate, 

 thickly pilose with long golden hairs; dorsal carina obsolete be- 

 fore horns, percurrent behind them; humeral angles prominent 

 and auriculate ; suprahumeral horns arising from extreme dorso- 

 lateral margin of pronotum, very thin as seen from the front, 

 distance between their bases almost twice as great as length of 

 horn, horns extending strongly outward, upward, and backward.
