LeConte lutulentus Lee. 



A — Nearly similar to lutulenttis but still narrower and of a paler 



• brownish-flavate color, the head deep black, narrower; prothorax 

 narrower, slightl}^ elongate, otherwise almost similar, the foveae 

 still more feebly impressed; under surface of the hind body deep 

 black, excepting the pale side-pieces of the mesosternum and the 

 last ventral segment, which are abruptly pale, the prosternum, 

 epipleura and legs very pale rufo-flavate; in lutulentus the last 

 abdominal segment is not so abruptly pale. Length (cf ) 6.4 mm.; 

 width 2.1 mm. New Jersey elegantulus n. subsp.

 brownish-flavate in color, the under surface and legs similarly 

 pale, the basal and lateral parts of the abdomen blackish; pro-

 and rather shallow, the intervals flat. Length (cf 9 ) 5.4-6.4

• broader, rather convex, shining, pale brownish-flavate, the head
