Hydroporus carolinus new species. 



Form rather broadly ovate, less than twice as long as wide, shining, 

 sparsely, finely ptibescent; head, thorax, antennae and legs rufous, elytra 

 brownish piceous with faint diffuse rufous spots at sides near the base (some- 

 times completely wanting), a postmedian lateral irregular rufous spot, and 

 the tip more or less obscurely rufescent. Prothorax slightly infuscate along 

 the basal margin and with a small diffuse fuscous spot at the middle of the 

 apical margin. Antennae entirely rufotestaceous. Head biimpressed as usual, 

 finely punctate, clypeus feebly thickened. Prothorax widely margined at sides, 

 rather coarsely, nearly uniformly punctate, the punctures separated by from 

 one to one and one half times their own diameters. Elytral punctuation simi- 

 lar to that of the prothorax, but slightly coarser. Metasternum and coxal 

 plates very coarsely, not closely, punctate ; apical margin of postcoxal processes 

 angularly prominent at middle. Front and middle tarsi of male moderately 

 and nearly equally dilated, the claws of the front feet evidently stouter and 

 more suddenly bent, but mutually equal. Length 3.75 to 4.1 mm.; width 2 

 to 2.2 mm. 



North Carolina (Highlands, June, '88). 



Described from a single pair (type 6) given me by the late Fred- 

 erick Blanchard, by whom they were collected. 



The combination of characters diagnostic of this species, are the 

 ovate form, obscurely marked elytra, coarse punctuation, wide thoracic 

 side margins, and slightly stouter equal front claws of the male. It 

 is most nearly related to mixtus Lee. The latter is of nearly similar 

 form, but the rufous color is brighter, the elytral markings conspicu- 

 ous, the side margins of the thorax narrower, the punctuation a little 

 less coarse, the front tarsal claws of the male unequal. 



Hydroporus brevicornis new species. 



Elongate oval, shining, sparsely, finely pubescent, broadly fuscocastaneous 

 on the disk, gradually changing to rufocastaneous at the margins. Head 

 rufous in front, darker posteriorly, finely, sparsely punctate, distinctly biim- 

 pressed, clypeus not thickened. Antennae unusually short, scarcely passing 

 the hind angles of the thorax, the intermediate joints but little longer than' 

 wide, rufous at base, becoming more or less completely infuscate apically. 

 Prothorax finely margined at sides, posterior lobe prominent, very sparsely,) 

 finely punctate at the middle of the disk, more strongly and closely so toward 

 all the margins. Elytra a little more coarsely punctate, nearly evenly so from 

 base to apex, the punctures separated by from one to two times their own 

 diameters. Beneath, prothorax, epipleurze and legs rufous, metasternum 

 black, abdomen piceous with tip and lateral spots on last three or four seg- 

 ments, rufous. Prosternal anterior intercoxal prominence moderate, meta- 

 sternum nearly flat along the median line; postcoxal processes conjointly sub-
