152 MEMOIRS ON THE COLEOPTERA 



flatter strial intervals; from simplex Dej., which it more nearly 

 resembles in the small head, it differs in its more elongate form, still 

 slightly smaller head, more apically narrowed prothorax, more 

 elongate elytra and flatter strial intervals; simplex is not identical 

 with elongatus, being smaller, with more abbreviated elytra and 

 smaller head. 



Dicaelus ovipennis n. sp. Elongate, rather slender and feebly convex, 

 somewhat shining, the elytra alutaceous, deep black throughout; head 

 elongate, relatively large, nearly as in teter but with still more elongate 

 neck and smaller apical impressions, two-thirds as wide as the prothorax, 

 the latter relatively small, a fourth wider than long, in general form, im- 

 pressions and sculpture nearly as in teter, but with more evenly arcuate 

 sides, widest at the middle and not before the middle as it is in that 

 species; elytra relatively much more inflated, evenly oval, with arcuate 

 sides, widest at the middle and nearly one-half wider than the prothorax, 

 one-half longer than wide, the striae, intervals and humeral carina as in 

 teter. Length (c?) 17.0 mm.; width 6.4 mm. North Carolina (locality 

 unrecorded). 



Allied rather closely to teter but differing very greatly in general 

 facies, because of its small parallel prothorax, with evenly rounded 

 sides, and the inflated elytra; the anterior tarsi of the male are less 

 dilated than in that species, the middle tarsi shorter, the second 

 palpal joint longer and the fourth shorter; the micro-granulation 

 of the elytra is less fine and stronger, so that the surface is more 

 opaque, especially at the sides. 



Dicaelus angustus n. sp. Form and facies nearly as in politus, the 

 integuments similarly deep black and polished; head and prothorax 

 relatively a little larger, the latter flatter and more nearly as long as wide, 

 much less distinctly narrower than the elytra, the impressions nearly 

 similar but the side margins anteriorly are less narrowly reflexed; elytra 

 broader, one-half longer than wide, barely a fourth wider than the pro- 

 thorax, the sculpture throughout similar. Length 14.0 mm.; width 5.0 

 mm. Tennessee. 



This species is allied closely to politus Dej., but is a little larger 

 and broader, with larger and more depressed, more quadrate pro- 

 thorax ; it differs very perceptibly in habitus from any one of a very 

 large series of politus, kindly given me by Mr. A. B. Champlain 

 and taken at Rockville, Pennsylvania, and others from Indiana in 

 the Levette collection, the latter examples agreeing perfectly with 

 the former. 



Dicaelus speciosus n. sp. Form and coloration nearly as in splendidus, 

 but with a notably smaller head, this being barely at all more than half
