838 Goleopterological Notices, V2. 



A. dilatatiis n. sp. — Stout, the elytra very abruptly dilated behind the 

 base, black throughout; pronotuin with some velvety-black scales before the 

 middle and near the apex; elytra with the patches of white scales disposed 

 nearly as in huhbnrdi, the scales of the third interval in the posterior band 

 more prolonged anteriorly; each of the large foveas with a broad whitish scale. 

 Head finely, strongly punctate and squamose, more than one-third as wide as 

 the prothorax, the interocular fovea extremely large and deep; beak stout, 

 dull, squamose at base, finely but strongly, not very closely punctate. Pro- 

 Ihorax slightly wider than long, strongly rounded at the sides, narrowed at 

 base and still more strongly toward apex, the latter one-half as wide as the 

 base; disk coarsely and closely punctate, the punctures coarser and more con- 

 fluent toward base; median carina strong at the middle, not attaining the base. 

 Elijtra not as long as wide from above, twice as long and twice as wide as the 

 prothorax, the post-humerdl protuberancies extremely developed, their oblique 

 anterior sides deeply emarginate midway to the base; sides strongly convergent 

 and rounded behind the tubercles, the apex obtuse; disk deeply perpendicular 

 behind in profile, having deep series of very large contiguous subtransverse 

 fovese, the series separated by strong tuberculiferous ridges, the humeral ridge 

 most pronounced. Abdomen sparsely punctate and squamose; legs densely 

 and unevenly clothed with scales. Length 8.0 mm. ; width 5.6 mm. 



Florida. Mr. Jiilieh. 



The single specimen in my cabinet, which was probably taken 

 in the extreme southern part of the State, represents a close ally 

 of hubbardi, differing in the greater development of the post- 

 humeral tubercles and consequently much stouter form of the body, 

 but more particularly in the very close and roughly tuberculose 

 sculpture, deeper and less elongate frontal fovea and other char- 

 acters. The elytral fovese are so closely crowded that they 

 coalesce, producing deep broad furrows between the ridge-like 

 intervals, while in hubbardi the fovese are isolated and rounded.
