posterior half, but the sutural margin throughout with 
larger uniform granules, and towards the apex elevated 
or ridged, the apex itself rounded, preapical callus 
moderately prominent; body beneath and legs with 
numerous minute narrow silaceous scales. 
Armiticus gibbosus. 
A. latiusculus, subellipticus, niger, squamulis silaceis 
sat confertim instructus ; prothorace brevi, leviter granu- 
lato, elytris in medio gibbosis, striato-punctatis, inter- 
stitiis irrregulariter granulatis, postice singulatim plaga 
albida notatis. Long. 6 lin. 
Hab. Brazil. 
Rather broad, subelliptic, black, with glossy granules 
above, the intervals closely covered with silaceous 
scales ; rostrum longer than the prothorax, somewhat 
robust, scarcely curved, coarsely punctured at the base ; 
antenne rather long, the second joint of the funicle three 
times as long as the first, the rest gradually shorter, 
club not longer than the last four together ; eyes shortly 
ovate; prothorax nearly twice as broad as long, con- 
tracted at the apex, the side well rounded, numerous 
small glossy granules irregularly scattered on the disk, 
few or none at the sides, in the middle a short raised line; 
scutellum narrowly triangular, covered with white 
scales; elytra broader than the prothorax, shoulders 
and sides rounded to the apex, convex to the middle, 
then gradually depressed to near the apex, when it again 
rises between the two preapical calluses, striate-punc- 
tate, the alternate interstices raised into an irregular 
ridge of sloping granules, each generally having one or 
occasionally two white scales at the base posteriorly, the 
other interstices with a few normal granules mostly con- 
fined to the anterior half; body beneath and legs with 
narrow silaceous scales; tarsi rather dilated ; claw-joint 
small. 
A peculiar species ; in some respects, especially in the 
shortness of the prothorax, approaching A. brevicollis; 
without, however, claiming too close an affinity, I think 
it may well stand as a congener of the above. 
Arniticus brevicollis. 
A. oblongus, piceus, squamulis angustatis silaceis 
indutus; elytris modice convexis, pone medium macula
