510 SUPPLEMENT. 
8. Eusattus sculptus. 
Broad-oval, convex, black, almost glabrous, the head and prothorax opaque, the elytra slightly shining. Head 
and prothorax smooth or exceedingly minutely punctate, the prothorax deeply grooved at the sides behind, 
the lateral margins moderately thickened ; elytra each with six rather broad, faint costs, without marginal 
carina, the interspaces rather coarsely, confluently punctate, and feebly transversely reticulate ; epipleure 
and flanks of the prothorax slightly hairy, the epipleure gradually widening to the base and feebly 
punctured ; prosternum strongly, horizontally produced, the apex immarginate ; anterior tibie strongly 
produced at their outer apical angle. 
Length 93-13, breadth 53-8 millim. 
Hab. Mexico, Northern Sonora (Morrison), Paso del Norte, Villa Lerdo in Durango 
(Hoge). 
Sent in abundance by Herr Hége from the Mexican frontier. The elytra are sculp- 
tured as in E. reticulatus, but they are without a marginal carina; in some specimens 
the basal portion is smooth. The thorax is deeply grooved on either side behind, so 
that the margins appear to be somewhat expanded posteriorly. The elytral punctuation 
shows no tendency to become muricate. Dr. Horn, to whom I have forwarded an 
example, informs me that this species also occurs in Arizona and Colorado, and that it 
is allied to E. difficilis, which has the epipleure more hairy and the elytral sculpture 
muricate. 
9. Eusattus mexicanus. 
Oblong-oval, broad, convex, dull black, almost glabrous. Head finely, sparsely punctate, strongly trisinuate in 
front, the anterior margin reflexed and grooved within; prothorax minutely, sparsely punctate on the 
disc, the punctures more distinct towards the sides; elytra with three more or less distinct raised lines 
on the disc, without marginal carina, the interspaces finely transversely reticulate and rather coarsely 
punctured, the inflexed portion sparsely punctate; the flanks of the prothorax with a few hairs; the 
epipleure abruptly widened at the base, smooth, almost glabrous ; prosternum very broad, rather convex, 
moderately produced, the apex broadly rounded and immarginate; anterior tibie strongly and somewhat 
obtusely produced at their outer apical angle. 
Var. The elytral coste nearly or quite obsolete. 
Length 93-14, breadth 53-83 millim. 
Hab. Mexico, Villa Lerdo in Durango, Colima city, Sayula in J alisco, Chilpancingo 
(Hoge). 
Sent in considerable numbers from Sayula. This species. closely resembles L. venosus, 
but differs from it in having the anterior margin of the head more strongly trisinuate 
and more distinctly carinate; the elytra are without marginal carina and usually have 
three raised lines on the disc—these being obsolete in some of the Colima and Villa 
Lerdo specimens,—the interspaces reticulate and rather coarsely punctate, the punc- 
tures here and crowded together in large shallow fovee ; the prosternum is very broad. 
10. Eusattus obliteratus. 
Oblong-oval, black, opaque. Head and prothorax very sparsely, minutely punctate; elytra with exceedingly 
shallow, rather coarse, widely scattered punctures, and here and there faintly, transversely wrinkled, and 
usually with indications of broad obsolete coste, each puncture bearing a very minute scale-like hair,
