GONIOCLGUS. 325 
sternal process curved backwards at the apex, the apical edge hardly projecting beyond the base of the 
metanotum. Abdominal segments 2—4 of the ¢ mesially subcarinate, segment 5 of ¢ more punctured and 
less convex than in the ¢ of G. orbitalis. 
Length 9-104 millim. 
Hab. Nicaraaua, Chontales (Belt); Panama, Volcan de Chiriqui [type] (Champion). 
Three males and one female. The male from Chontales differs from the type in some 
details, the frons being rather wider, the abdomen less distinctly carinate, &c., but 
evidently belongs to the same species. 
4. Goniocleus tholerus, sp. n. 
3 2. In colour practically the same as G. funereus. Rostrum one-third broader than long, very densely and 
coarsely punctured, like the head. Tenth antennal segment broader than long in both sexes, eleventh 
as long as broad in the ¢, broader in the 9. Pronotum cvarsely punctured, except at apex and on the 
callosities, which stand in front of the carina, the middle one of which is rather more elevate than in 
the preceding ; carina angulate in the middle, the angle pointing backwards. Elytra coarsely punctured 
and pustulated as in G. funereus ; the base of both together feebly emarginate, almost straight ; post- 
median tubercle of fifth interspace closer to the large postmedian tubercle of the third interspace than 
in G. funereus. Prosternum coarsely punctured. Abdomen feebly convex along the middle in the ¢. 
Length 8-9 millim. 
Hab. GuatEMAta, Chacoj and San Gerénimo in Vera Paz (Champion). 
One pair. 
5. Goniocleus fractus, sp. n. 
9. Like G. tholerus. Rostrum longer, not so coarsely punctured. Frons one-third the width of the 
rostrum. End-segment of antenna a little wider than long. Pronotum without distinct callosities, 
though depressed at each side near middle in front of carina; the latter rather widely interrupted in 
middle. Apical tubercle of elytron less prominent than in G. funereus and G. tholerus; seventh 
interspace without tubercle in middle. 
Length 9 millim. 
Hab. Panama, Bugaba (Champion). 
One female. 
6. Goniocleus niger. (Tab. XI. figg. 30, 30a.) 
Monocleus niger, Jordan, Nov. Zool. xi. p. 260. n. 37 (1904) *. 
In this species, which was originally described from a single specimen, the pronotum appears almost smooth, 
the punctures not being so large as in G. fractus, G. tholerus, and G. funereus, and the mesial callosity 
vestigial. 
Hab. Costa Rica, Zarzero! (Schild-Burgdorf, in Mus. Tring); Panama, Volcan de 
Chiriqui (Champion: one male, two females). 
7. Goniocleus carbonarius, sp. n. 
g. Upperside irrorated with clay-colour, which forms a narrow, interrupted, mesial vitta on pronotum. 
Rostrum and frons very coarsely punctured ; the former one-third broader than long ; frons less than 
one-third the width of the rostrum. Pronotum with large punctures from the carina forward, except
