Coleopterological Notices. 147 



Elytral punctures extremely fine and sparse, separated by from three to five 

 times their own diameters. 

 Elytra and abdomen alutaceous, the latter excessively feebly, minutely 

 punctate, the punctures very sparse, scarcely visible and not appreci- 

 ably more distinct laterally ; elytral pubescence very minute and sparse. 



nioiitaniis 



Elytra and abdomen strongly shining, the latter very minutely but rather 



distinctly punctate, the punctures sparse, very slightly larger near the 



apex, and less distinctly so near the sides perpolitiis 



Pronotum highly polished throughout and perfectly devoid of reticulation at 

 the sides. 



Punctuation of elytra denser, deeply impressed and very distinct ater 



Punctuation sparser and very feebly impressed, almost invisible near the 

 sides and suture iiitidlllus 



Group II. 

 LiMNiCHiTES u. subgen. 



Abdomen densely, coarsely cribrate ; pimctures of the pronotum very dense. 

 Larger species, oval ; sides distinctly arcuate ; punctures of the elytra 



slightly separated piiuctattis 



Smaller species, more oblong, with the sides nearly straight in the middle ; 



punctures of the elytra larger, polygonally crowded neliulostis 



Abdomen densely, coarsely cribrate toward the sides, but sparsely and much 

 more finely punctate toward the middle and base ; punctures of the pronotum 

 fine in the middle, sparse, those of the elytra rather fine, separated by dis- 

 tinctly more than their own diameters olivaceiis 



Abdomen more sparsely pianctate ; punctures of the pronotum toward the 

 middle sparse and fine ; punctures of the elytra very narrowly separated. 



perforatiis 



Group III. 

 LicHMiNcs n. subgen. 



Ovate, pointed behind ; piabescence rather fine, recumbent, moderately dense, 

 dark brown in color tenuicornis 



Group IV. 

 LiMNiCHODERus u. subgcn. 



Abdomen completely devoid of punctures ;i each elytron with a subapical and 

 two lateral submedian indefinite patches of paler pubescence. 



naTicitlatus 



1 In this subgenus the abdomen is always rendered more or less dull by an, 

 extremely minute rugose reticulation. The punctures here referred to are 

 entirely distinct from this ; they are deep and perforate, and distributed 

 generally somewhat unevenly over the surface.
