in middle of apex and on the callosities, mesial callosity distinct. Tubercles of elytra less elevate than 
in all the preceding species ; the basal tubercle the largest, the second and third of the third interspace 
not much longer than the fourth, lateral tubercles (in fifth and seventh interspaces) small, but distinct ; 
basal edge of each elytron somewhat rounded, not emarginate; punctures large. End-segment of 
antenna hardly longer than broad. 
Length 6 millim. 
Hab. Guatema.a, Panzos in Vera Paz (Champion). 
Two males. 
8. Goniocleus laticeps, sp. n. 
2. Close to G. carbonarius. Rostrum twice as broad as long, narrowed from antenne forward, very densely 
punctured. Frons more than half the width of the rostrum. End-segment of antenna luteous, as long 
as broad. Prothorax nearly half as broad again as long, densely punctured except a narrow space 
along apical edge ; mesial callosity not much elevate, bearing also some punctures ; dorsal carina feebly 
angulate in middle, the angle pointing backwards. Tubercles of elytra not provided with clayish tufts, 
the second and third of the third interstice elongate, less elevate than the first, no fifth tubercle in third 
interstice. Legs black-brown, tibia with an indistinct grey ring near base.

9. Goniocleus tarsalis. (Tab. XII. figg. 1, 1a.) 
Goniocleus tarsalis, Jordan, Nov. Zool. xi. p. 263. n. 43 (1904) *. 
There is a ¢ in the Godman and Salvin collection which I believe is that of G. tarsalis, described from 
a Q from Costa Rica. It bears a conspicuous luteous-grey spot on the pronotum extending from the 
mesial tubercle to the base. As the specimen differs also somewhat in structure from the three females 
known to me, I append a description of it. 
Rostrum not quite twice as broad as long, with shallow depressions, not densely punctured. Hye twice as 
long as broad. Frons one-third the width of the rostrum. Club of antenna slender, segment 10 half 
as long again as broad, 11 one-fourth longer than wide. Pronotum with three feebly elevate callosities, 
punctured from carina forward, except in these callosities and in middle of apex; carina feebly curved 
backwards in middle. Elytra emarginate together at base, coarsely punctured ; four tubercles in third 
interspace, the second small, the third very large, the fourth minute; interspaces 5, 7, and 9 pustulated 
and tubercled, the last tubercles of the seventh interspace rather acute and prominent; sutural angle 
raised into a prominent tubercle. Underside somewhat villose in middle; prosternum punctured ; 
mesosternal process slanting; abdomen minutely punctured in middle. Posterior trochanter not 
mucronate; mid tibia with spur at apex ; claw of hind tarsus with tooth. 
Length 10 millim.

10. Goniocleus politus, sp.n. (Tab. XII. figg. 2, 2a.) 
$ 2. Rufescent-brown, strongly glossy, clothed with an ochraceous pubescence, more or less variegated 
with grey beneath ; base of antenna and the legs more or less rufous, tibie with a brown ring in middle ; 
club of antenna blackish, the last segment not being luteous. 
Rostrum twice as broad as long, with a short obtuse mesial carina which does not reach apex, coarsely 
punctured like head. Pronotum short, at least half as wide again as long, with three prominent 
tubercles of nearly equal height, dise punctured around these tubercles. Elytra nearly straight at base,
