414 Coleopterological Notices. 



U. ma ri t iimis n. sp. — Elliptical, rather strongly convex, piceous 

 throughout, polished ; pubescence short, very coarse, recumbent, rather 

 sparse but pale flavate and conspicuous. Head much wider than long, feebly 

 convex, rather finely and sparsely punctate; epistoma strongly sinuate; 

 upper lobes of eye large, separated by scarcely four times their own width, 

 circular ; antennae slender but strongly compressed and dilated toward apex, 

 distinctly shorter than the head and prothorax, third joint slender, nearly 

 twice as long as wide and but slightly longer than the fourth, eleventh fully 

 as wide as the tenth and much longer, slightly wider than long, the apex 

 obtusely and rather obliquely rounded. Prothorax twice as wide as long ; 

 apex about four-fifths as wide as the base, broadly, deeply emarginate ; base 

 broadly, rather strongly arcuate in the middle, the lobe extending posteriorly 

 distinctly beyond the basal angles, broadly sinuate laterally ; basal angles 

 slightly acute, not at all rounded ; sides evenly, strongly arcuate throughout, 

 very feebly convergent anteriorly in basal half; disk somewhat coarsely and 

 sparsely punctate. Scutellum polished, with a few minute widely scattered 

 punctures toward base. Elytra in the middle slightly wider than the protho- 

 rax, more than three times as long ; sides evenly arcuate ; apex acute ; disk 

 with extremely feebly impressed series of coarse deep perforate punctures, 

 which are generally separated by nearly twice their own diameters ; intervals 

 flat, smooth, polished, minutely and sparsely punctate, equally pubescent 

 throughout. Abdomen, sparsely punctate, the punctures deep, gradually very 

 coarse and denser toward base ; pubescence short, sparse, pale and very stout. 



Male. — Anterior tarsi robust but not distinctly dilated, with very small 

 narrow tufts of fine yellow pubescence beneath, the basal joint very obsoletely 

 tutted ; intermediate tarsi and abdomen not modified. 



Length 4.9-5.7 mm. ; width 2.5-2.9 mm. 



Texas ; Florida. 



This species is similar in form to fimbriatus, but differs in its 

 smaller size, coarser and more distant strial punctures, larger eyes, 

 shorter pronotal fimbria? and many other characters ; it is peculiar 

 to the sand dunes which line the ocean beaches, and I have taken it 

 in considerable abundance at Galveston. The sexual modifications 

 of the male are extremely feeble. 



U. elongatulUS n. sp.— Elongate-elliptical, very moderately convex, 

 piceous-black throughout, rather shining ; pubescence short, robust, moder- 

 ately dense, pale ochreous-rlavate and conspicuous. Head strongly transverse, 

 rather coarsely deeply and densely punctate, the punctures distinctly sepa- 

 rated ; epistoma deeply sinuate ; upper lobes of eye moderately large, separated 

 by fully five times their width ; antenna? slender toward base, strongly dilated 

 toward apex, third joint slender, more than twice as long as wide, joints three 

 to five uniformly and somewhat rapidly decreasing in length, eleventh fully 

 as wide as the tenth, nearly as long as wide, narrowly and squarely truncate 

 at apex. Prothorax a little more than twice as wide as long; apex rather
