SCLOMIAS. 173 
placed as near to the insertion of the antenne as to the front of the thorax. The 
latter subcylindric, not longer than broad, very slightly rounded at the sides in the 
middle, the sculpture obscured by the squamosity, which, however, is not dense. 
Scutellum not distinct. Elytra convex, rising suddenly from the base of the thorax, 
their base not wider than the base of the thorax, but becoming rapidly broader, much 
narrowed towards the apex, so as to be acuminate behind; with series of coarse 
punctures, and clothed with a white squamosity distributed vaguely into spots, and 
also set with erect truncate sete. Under surface not squamose; second, third, 
and fourth ventral plates armed with erect, pallid, rigid sete or bristles. Three 
specimens. 
2. Sciomias subtilis, sp. n. (Tab. VII. fig. 11.) 
Fusco-brunneus, subtiliter ochraceo-squamosus, subvariegatus; antennis tibiis tarsisque testaceis; elytris 
ovalibus, convexis; setis subtilibus raris armatus., 
Long. 37 millim. 
Hab. Mexico, Omilteme, Chilpancingo (H. H. Smith). 
Antenne not elongate, unicolorous, yellow ; first joint of funiculus moderately long, 
stout, nearly twice as long as the second. Rostrum moderately long, a little breader 
at the tip; eyes convex, coarsely facetted, placed but a short distance in front of the 
thorax, very widely separated from one another. Thorax cylindric, covered with a 
delicate squamosity or setosity, which, however, is not dense. Elytra convex, almost 
regularly oval, with striz that are well marked and moderately coarsely punctured ; 
with a fine squamosity arranged so as to give a slight variegate appearance, and with 
some distant, excessively fine, rather short, erect hairs. Under surface piceous, not 
squamose, bearing only a few extremely fine hairs. Five specimens. 
3. Sciomias rugicollis, sp. n. 
Piceus, parcius squamosus, parcius breviterque hispidus ; antennis pedibusque rufis; prothorace angusto, 
fortiter rugoso-punctato ; elytris profunde punctatis, interstitiis subconvexis. 
Long. 2? millim. 
Hab. Guaremaa, San Gerdénimo (Champion). 
Antenne unicolorous, not long, scape slightly bisinuate ; first joint of funiculus 
not elongate, second quite small. Rostrum a little broader towards the tip, very 
coarsely sculptured ; eyes not very widely separated, placed at a considerable interval 
in front of the thorax. The latter slender, but rounded at the sides, very densely and 
coarsely sculptured. Elytra oval, with very regular series of large punctures, the 
interstices somewhat convex, bearing a scanty squamosity and also an exudation which 
when removed brings away the scales; there are also very short, erect, truncate, 
pallid seta. Two specimens.
