various Central American Coleoptera. 65 
eleventh, the margins of the thorax, and the tarsi more or less 
ferruginous. Head and thorax with a few widely scattered ex- 
cessively minute punctures (only visible under the microscope) ; 
antennae with joint 3 elongate, 4-6 gradually decreasing in length 
and increasing in width, 4 and 5 obconic, 6 angular within, the 
5-jointed club larger (the small strongly transverse eighth joint 
excepted); thorax strongly sinuate at the apex; elytra closely, 
finely, confusedly punctate, without trace of striae on the disc, the 
sutural stria shallow and running from about the middle to the apex. 
Beneath with excessively small and widely scattered punctures, 
each bearing a minute hair; prosternum deeply excavate laterally ; 
posterior coxae deeply grooved for the reception of the femora, 
the coxae raised greatly above the level of the first ventral segment ; 
fifth ventral segment unimpressed; legs long, tibiae narrow, tarsi 
slender, 4-jointed. 
Length (excl. head) 3, breadth 23; mm. (9.) 
Hab. Mexico, Omilteme in Guerrero, 8,000 feet (H. H. 
Smith). 
One specimen. Larger than the European L. orbicularis, 
the antennae more elongate, the legs longer and more 
slender, the elytra without trace of dorsal striae, and with a 
shallower sutural stria, the under surface almost smooth. 
L. confusus, Horn, is said to have rather coarsely punctate 
elytra.

Matthews enumerated three species of this American 
genus, including A. laevis, Lec., the type, from Central 
America. Two others are contained in our collection. 
The characters of Aglyptus have been given at great length 
by both Horn and Matthews, but I can find no mention 
of the very conspicuous curved impressed line (resembling 
one of the ventral sutures) which extends outward across 
the first ventral segment to a little behind the middle of 
the outer margin. Matthews, it is true, describes “ the 
basal segment as slightly but broadly elevated in a curved 
line at its base, enclosing the whole length of the coxa,’ 
but as the line is distinct from the coxa this definition is 
scarcely accurate. The anterior tarsi are said by Horn
