1. Goniocleus umbrinus. (Tab. XI. figg. 27, 27 a, 6.) 
Goniocleus umbrinus, Jordan, Nov. Zool. xi. p. 264. n. 45 (1904) *. 
Easily recognized by the mesial carina of the rostrum extending from the base to near the apical edge. 
Hab. Mexico}, Toxpam (Sallé); Guatemata, San Juan in Vera Paz (Champion), 
Coban in Vera Paz (Conradt) ; Nicaragua, Chontales (Belt, Janson); Panama, Volcan 
de Chiriqui (Champion). 
Numerous specimens. 
2. Goniocleus orbitalis. (Tab. XI. figg. 28, 28 a.) 
Stroboscopus orbitalis, Lacord. Gen. Col. vii. p. 584, nota 1 (1866)*; Gemm. & Har. Cat. Col. 
ix. p. 2733 (1872) *. 
3 2. Head and rostrum dispersedly punctured. Eye edged with buff; dots of similar pubescence also on 
the prothorax and elytra, those on the latter numerous in the seventh and ninth interspaces and in 
the posterior half of the first and third. Pronotum almost smooth, there being only a few punctures 
on the disc at each side of the slight mesial callosity, and some more punctures towards the lateral carina. 
The mesosternal process is very slightly bent backwards at the apex, the apical edge projecting below 
the metasternum as a distinct ridge. The punctures of the elytra are small and the stripes hardly at all 
impressed. 
Hab. Mexico, Toxpam (Salle). 
One male and two females. 
3. Goniocleus funereus, sp.n. (Tab. XI. figg. 29, 29 a, 6.) 
3 2. Similar to G. orbitalis. The pubescence more variegated, especially on the pronotum ; elytron with a 
few buff dots, of which one stands on the postmedian tubercle of the third interspace. 
Rostrum shorter and, like the frons, much more densely and coarsely punctured. End-segment of antenna 
longer than in G. orbitalis, being longer than broad. Puncturation of pronotum also coarser and more 
extended. Elytra again coarsely punctured; fifth interspace with a tubercle in between the subapical 
tubercles of the third and fifth interspaces, all the interspaces being more or less pustulated. Meso-
