[LeConte. 



10. A. crassulus, n. sp. 



Rather robust, black, densely clothed with dark brown scales, and enct 

 thick bristles, which are shorter upon the prothorax. The latter is about 

 as long as wide, rounded on the sides, slightly wider at the middle, much 

 narrowed in front and broadly constricted; densely punctured, with a few 

 pale brown scales at the sides, and a small spot at the middle of the base. 

 Elytra as in A. davatus; brown towards the base, and with an irregular, 

 broad, yellowish brown band behindi occupying the posterior third of the 

 elytra. Legs clothed with yellow browji scales. Length 3.5 mm. ; .10 inch.

11. A. longulus, n. sp. 



This species is colored exactly like the preceding, but is of verj- different 

 form, and the bristles of the elytra are longer. The prothorax is a little 

 longer than wide, and is distinctly- wider at the middle than at the base. 

 The elytra are oblong, nearly parallel on the sides, suddenlj' wider at base 

 than the prothorax, with the humeral angles prominent and rounded; less 

 obliquely narrowed, and more broadlj' rounded behind than usual. Length 

 2.5 mm. ; .10 inch. 



Haulover, Florida; Messrs. Hubbard and Schwarz. I should consider 

 this as the cT of the preceding species, if the bristles of the elytra were not 

 so much longer. The form of the elytra is quite different from any other 

 Acalles known to me, and resembles that seen in certain small CryptoThyn- 

 chi. The longitudinal distance between the middle and hind coxte is also 

 greater than in the other Acalles, and full^- as great as in C. minutissiinun ; 

 but the metathoracic episterna are not visible, while in the insect last named 

 they are narrow, and very apparent. 



12. A. nuchalis, n. sp. 



Veiy robust, clothed witli brown scales, dark and paler intermixed. Beak 

 strongly punctured and sulcate, linely carinate, occiput clothed with pale 

 scales. Prothorax neai'ly twice as wide as long, rounded on the sides, 

 scarcely wider at the middle, then rapidly narrowed to the tip, but not con- 

 stricted; coarsely and densely punctured, with three very indistinct pale 

 brown lines; a slight trace of a narrow median smooth line. Elytra ovate, 

 truncate at base, much rounded on the sides, obliquely narrowed behind; 

 l)asal angles obtuse, not prominent; striae composed of large, quadrate punc- 

 tures; interspaces wide, slightly convex, each with a row of moderately 

 long, pale, clavate bristles; the scales of the posterior third are more mixed 

 with yellowish brown, and are limited in front by an angulated line of pale 

 scales extending to the fifth stria. Beneatli nearly black, with scattered 

 pale scales; mesosternum less deeply emarginate than in the preceding 

 species, but more strongly than in A. pectoralis. Metasternum as short as 

 in the other species, but with the episterna narrow and distinct. Length 

 4 mm. ; .16 inch. 



Capron, Florida; Messrs. Hubbard and Schwarz; one specimen. An 

 anomalous species, which with the form of Acalles combines the distinct
