NORTH AMERICAN COLEOPTERA. 11)5 



than the head and thorax, joints 4-10 broader than long; head sub-orbicular, hind 

 angles smooth ; thorax wider than the head, not longer than wide, very slightly 

 narrowed in front, feebly sinuate when viewed laterally, dorsal punctures large 

 and deep, equidistant; elytra a little wider than the thorax, conjointly a little 

 wider than long, sparsely not coarsely punctate, rarely with a slight aeneous tinge ; 

 abdomen sparsely punctate, the punctures finer than those of the elytra; beneath 

 more coarsely punctate, the margins of the segments paler. Length .20 — .25 inch ; 

 5—6.5 mm. , 



il/rt/e.— Anterior tarsi very broadly dilated, patellate ; last ventral segment tri- 

 angularly emarginate, the emargination surrounded by a moderately wide gutter. 

 i^e/«a/e. — Anterior tarsi narrowly dilated; last ventral entire. 



The color of this species is variable. The ^e,<^s are, however, always 

 pale, and the tibiae and tarsi usually darker. It differs from the other 

 patellate species in the absence of the longitudinal impression of the last 

 ventral segment. I have seen some darker varieties labeled iiisipiens Fv. 

 in cabinets. 



Occurs in Europe and Africa, and in our fauna is found everywhere 

 in the eastern Atlantic region, extending as far west as Kansas and 

 Nebraska. 



I*. Tarians Payk. — Black, elytra sometimes brown, legs piceous; antennpe 

 piceou.s, a little shorter than the head and thorax, joints 4-10 scarcely longer than 

 wide ; head orbicular, hind angles sparsely punctured ; thorax wider than the 

 head, not longer than wide, very distinctly narrowed in front; sides not sinuate, 

 dorsal punctures moderate, equidistant; elytra a little wider than the thorax, con- 

 jointly nearly square, densely punctured, feebly shining, sparsely pubescent; ab- 

 domen somewhat iridescent, more coarsely and less densely punctured than the 

 elytra; beneath similarly punctured. Length .20 — .26 inch; 5— 6. 5 mm. 



A/'(/e. — Anterior tarsi moderately dilated; last ventral segment triangularly 

 emarginate, the emargination surrounded by a gutter, which extends slightly for- 

 ward on the segment. 



J^ewm/e.— Anterior tarsi slightly dilated ; last ventral entire. 



The determination of this species is based on specimens returned by 

 Fauvel to Mr. Schvvarz so labeled. The form occurring with us is the 

 variety agilis. I have suppressed niger Mels. as entirely synonymous. 



This species is nearly cosmopolitan. In our fauna it occurs in the 

 n:irthern portions of the Atlantic region, extending westward to Wash- 

 ington Territory and California. 



I*. I<»iigi(;ornis Sleph. — Black, shining; antennte piceous, nearly as long as 

 the head ;nid tlmrax. joints 4-1 a little longer than broad; head oval, hind an- 

 gles slightly punctate; thorax oval, a little longer than wide, distinctly narrowed 

 in front; sides scarcely sinuate, dorsal punctures moderately deep, the posterior 

 more distant; elytra wider than the thorax, conjointly a little wider than long, 

 moderately densely sub-muricately punctured, sparsely pubescent, sometimes 

 slightly aeneous; abdomen rather finely and densely punctured, especially at the 

 base of the segments; beneath finely densely punctulate, distinctly iridescent. 

 Length .24— .30 inch: 6—7.6 mm.
