more indefinite behind, so that it may be doubted whether it should remain in 
Epicerus ; but as E. squamosus to some extent connects it with # meaicanus, the 
typical species of the genus, I think it would be wrong to separate it at present. The 
truncation of the tip of the hind tibia is almost completely absent in Z. oscillator, but 
this is also the case with some other species of Epicwrus. 
We have received only three examples of this species. It apparently varies in a 
similar manner to Z. mexicanus, the sculpture and squamosity being a little dissimilar 
in each of the examples. The male is much smaller than the female, but exhibits 
scarcely any difference in the shape of the elytra. 
30. Epicerus minor, sp. n. (Tab. V. fig. 9.) 
Brevis, convexus, niger, squamosus, hispidus, subvariegatus; antennis rufis; rostro brevi, fere squali, fronte 
fovea elongata munita. 
Long. 53 millim. 
Hab. Guaremata, San Gerénimo (Champion). 
Rostrum very short, not broader in front, covered with scales, the nasal plate very 
prominent, polished, the forehead with a deep elongate fovea; the eyes large, not 
prominent. Thorax short, much rounded at the sides, deeply and coarsely punctate, 
covered with griseous scales, the basal margin distinct. Elytra densely squamose, the 
squamosity griseous, whitish, and fuscous, but not forming a definite pattern; with 
regular series of fine punctures, the interstices very broad but scarcely perceptibly 
convex. One specimen. 
I can detect no good character for distinguishing this insect from Hpicerus, though 
the apex of the hind tibia is so simple that Lacordaire would no doubt have considered 
the corbels to be open. There is, however, much variety in Epicerus as to this 
character, and even in £. minor there is visible a slight incrassation of the apical face 
of the outer lamina, so that I consider the corbels to be cavernous in a rudimentary 
degree. The insect bears a good deal of resemblance to Epagrius pumilus and LE. levi- 
nasus, but they have broader scrobes. 
31. Epicerus monclove, sp. n. (Tab. V. fig. 10.) 
Brevis, convexus, dense griseo-squamosus, minute setosus; elytris seriatim fortiter profunde punctatis. 
Long. 7 millim. 
Hab. Mexico, Monclova in Coahuila (Dr. Palmer). 
Antenne rather stout, the second and third joints equal in length; club rather long, 
dark in colour. Rostrum short and broad, densely squamose, and bearing white sete, 
feebly impressed along the middle; eyes moderately convex, the fovea between them 
obsolete. Thorax convex, transverse, narrowed in front and a little rounded at the 
sides, densely squamose, without depressions or channel. Elytra convex, truncate at
