158 Mr. G. C. Champion’s Notes on 
Priotoma contracta. 
Dorcatoma contracta, Gorh., Biol. Centr.-Am., Coleopt. 11, 
2, p. 209 (part.). 
Priotoma contracta, Gorh., loc. cit. p. 351 (part.). 
Short ovate, convex, shining, varying in colour from black to 
castaneous, the antennae in some specimens wholly rufo-testaceous, 
in others infuscate, the tarsi rufo-testaceous; sparsely clothed with 
rather long whitish hairs. Head and thorax very sparsely, minutely 
punctate; eyes moderately large, widely separated, feebly excised ; 
antennae apparently 9-jointed—(3) long, with the dentiform first 
joint of the club greatly produced inwards, and the succeeding joints 
broad and elongate, (2) shorter, and with the joints of the club 
smaller; elytra very sparsely, finely, subseriately punctate, the 
punctures becoming coarser and more crowded towards the suture, 
the two submarginal striae deep, the subhumeral stria short, the 
humeral callus moderately prominent, the latero-submedian promin- 
ence wanting. Beneath finely, the middle of the metasternum 
coarsely, closely punctate; ventral segments connate in the centre. 
Length 11-13, breadth 1-13, mm. (¢ 9.) 
Hab. Mexico, Teapa in Tabasco (H. H. Smith); GuatE- 
MALA, Capetillo, Aceituno, Cahabon (Champion); Panama, 
Tolé (Champion). 
Eleven examples. Gorham first included P. contracta 
in his section of Dorcatoma with 8-jointed antennae, sub- 
sequently placing it in Priotoma to which he ascribed 10 
joints, though the actual number of joints is nine. The 
feebly excised eyes, the partially connate ventral segments, 
the absence of the latero-submedian elytral callosities, the 
narrower form, and much smaller size, at once separate 
P. contracta from the other species he confused with it, 
which is described above under the name Caenocara quercus. 
P. tenuistriata and P. brevis (Gorh.) are larger allied forms.

Short ovate, convex, shining, black, the antennae and tarsi rufo- 
testaceous, the femora and tibiae rufo-piceous; sparsely clothed 
with long whitish hairs. Head and thorax very sparsely, minutely 
punctulate; eyes very large, separated above by about the width
