1(a). Doliema bifurcata. 
Reddish-testaceous, shining. Head finely, rather sparsely punctate; antennw very elongate in the male, 
shorter in the female; prothorax strongly transverse, considerably narrowed behind, the hind angles 
acute, the basal fovese very deep, the surface very finely, sparsely punctate; elytra elongate, parallel, flat, 
finely and lightly punctate-striate, the interstices sparsely punctate, the lateral carina sharp and 
extending nearly to the apex, the space between this and the marginal carina vertical. 
dS. The sides of the front dilated and thickened, and produced anteriorly into a short, broad lobe, which is 
emarginate at the apex, the emargination limited internally by an angular projection, and externally by 
a long, curved, downwardly-directed tooth; the epistoma extremely short, truncate in front, deeply trans- 
versely excavate on either side within. 
Length 43-5 millim. (¢ Q.) 
Hab. Mexico, Temax in North Yucatan (Gaumer). 
Six examples, two of which are males. Larger than D. plana; the lateral processes 
on the head of the male much broader and bifurcate in front, and without an additional 
tooth beneath. This last-mentioned character will easily separate D. bifurcata from 
the same sex of D. plana and D. pallida. 
2. Doliema pallida,

Doliema cucujiformis, huj. op. p. 158”. 
To the localities given, add :—Nortu America!, Middle and Southern States °. 
Dr. Horn has kindly forwarded male specimens of D. pallida and D. plana for 
examination. D. cucujiformis, Reitt., is inseparable from D. pallida. The male, as in 
the same sex of D. plana, has a small horn beneath the larger one on the head. 
2(a). Doliema quadridentata. 
g. Reddish-testaceous, shining. Head very broadly and deeply excavate anteriorly, densely, minutely punc- 
tate, the sides of the front thickened and strongly subangularly produced anteriorly, the epistoma large 
and angularly produced on either side at the apex; antennz elongate; prothorax strongly transverse, 
only a little narrowed behind, the hind angles acute, the basal fovese very deep, the surface very finely, 
sparsely punctate ; elytra elongate, parallel, flat, finely punctate-striate, the interstices sparsely, minutely 
punctate, the lateral carina sharp and extending nearly to the apex, the space between this and the 
marginal carina vertical. 
Length 53 millim. 
Hab. Mexico, Tehuantepec (Hége).
