428 CASEY 



more strongly rounded at base to the prothorax, with series of 

 rather coarse, close-set punctures, feebly impressed except lat- 

 erally, the interstitial punctures but little smaller than those of 

 the series, confused and closer toward base, sides and apex, 

 sparser centrally ; abdomen finely but strongly, sparsely punc- 

 tured medially, coarsely toward the sides; basal joint of the hind 

 tarsi equal in length to the fourth. Length S.6 mm. ; width 

 3.25 mm. Panama (Nata) * subaeneus n. sp. 



The Mexican and Central American species described by Mr. 

 Champion under the names Schoenicus salviin, viridt's, riififeSy 

 tmpressus^ ckalybeus, difficilis^ basalis and niger, belong to the 

 present genus and stibcBneus seems to be allied most closely to 

 salvini, differing in the form of the prothorax, which is said to 

 be widest at base in that species. The sides of the prothorax 

 in this and the preceding genus are very finely, though evidently, 

 margined, in marked contrast to the following two genera. 



Schoenicus Lee. 

 This genus is a constituent of the Floridian province of the 

 Caribbean faunal region, and is represented at present by a 

 single rather rare species, of comparatively small size and slen- 

 der form. It is distinguishable at once from Phcgoneus by the 

 exposed elytral humeri and large and very prominent, coarsely 

 faceted eyes, without vestige of supra-orbital carinee. The front 

 of the head, epistoma, mandibles, mentum and antennae are of 

 the usual type in the preceding genera, but the prosternum 

 between the coxaj is narrow and convexly declivous at the hind 

 margin of the coxee, and the mesosternum is not even tumid, 

 though its surface before the middle coxas is rapidly and strongly 

 depressed far below the level of the intercoxal part of the meso- 

 sternum and metasternum. The anterior and, to a less degree, 

 the middle tarsi, have conspicuous pads of fine dense pubes- 

 cence beneath, but the posterior are simply spinose and the 

 anterior and middle tibiie are feebly prolonged and acute at the 

 outer apical angle. The scutellum is moderately developed, as 

 long as wide and strongly ogival ; the upper line of the epipleurce 

 attains the very acute sutural angles. The type and only known 

 species may be outlined as follows : — 



Form elongate-subovai, convex, dark brownish-testaceous throughout, 

 shining and without evident metallic lustre, sparsely covered with
