arc deep and directed against the eyes, which are round, moderate in si/-. 

 and finely granulated. The front cox* are widely separated; the tihi;i- 

 gradually dilated and the front pair are pubescent towards the tip; a dis- 

 tinct spine is seen at the inner apical angle; terminal hook long; tarsi with 

 rather broad joints, third a little wider, feebly bilobed, last joint longer 

 than the others united; claws large, divergent. Scutellum distinct, elytra 

 with punctured striae, which are deeply impressed near the tip. 



1. M. linearis, n. sp. 



Very elongate, cylindrical, piceous or brown, shining, glabrous ; head and 

 beak finely punctured. Prothorax more than one -half longer than wide, 

 more strongly but not densely punctured, without impressions; slightly 

 narrowed in front, sides rounded near the base. Elytra not wider than 

 prothorax, stride composed of approximate punctures, deeply exarate on 

 the posterior declivity for a short distance. Beneath distinctly but finely 

 punctured ; flanks of prothorax feebly concave in front. Antennae and 

 legs reddish brown. Length 3 mm. ; . 12 inch. 



Haulover; Florida, March: Messrs. Hubbard and Schwarz; abundant on 

 the sea shore; no sexual differences observed. The fifth ventral segment 

 is longer than the third and fourth united; the three together are scarcely 

 longer than the first and second; the first ventral suture is obliterated, even 

 at the sides. 



ALLOMIMUS n. g. 



I cannot refer Cossonus dubius Horn, 1. c. 442, to any of the genera 

 described by Wollaston. It is nearly allied to Macrancyclus, but is of less 

 elongate form, and very much more coarsely sculptured; the elytra are in 

 fact rather sulcate than striate, though the deep stria? are coarsely punc- 

 tured, and the interspaces narrow with single rows of small punctures. 

 The beak is stout, cylindrical, a little narrower than the head, and nearly 

 as long as the prothorax; the antennal grooves commence in front of the 

 middle, and run directly towards the eyes, which are small, rounded, 

 moderately convex and not very finely granulated; the antenna? are not 

 very stout, the scape straight, strongly clavate, extending to the front mar- 

 gin of the eyes; funicle 7-jointed, first joint a little larger and stouter, 

 remaining joints short, closely united, gradually but slightly broader, club 

 large, oval-pointed, pubescent, annulated. Scutellum distinct. Front 

 coxae widely separated; thighs rather stout, tibia? dilated, with a small spine 

 at the inner angle; terminal hook long; tarsi with the third joint a little 

 wider, and feebly bilobed; last joint long, with divergent claws. 



1. A. dubius Horn. 1. c. 442 (Cossonus). 



I have seen but one specimen from Illinois; it is easily known by the 

 characters given above, and by the very coarse sculpture. Length 1.75 

 mm.: .07 inch. 



STENOMIMUS Woll. 



I think that Phlocophagus pallidm Boh., Sen. Cure, viii, 2d, 279; Cossonus 

 Horn. Proc. Am. Phil. Soc. 1873, 441, may properly be referred to this
