AMERICAN COLEOPTERA. 129 



A. septentrionalis, Lee. 



This is a somewhat more slender form than those which precede. 

 It differs notably by the absence of the oval finely-punctured space 

 on the prosternum and in lieu thereof a broad but feeble channel 

 extendino; from the tip of the prosternum nearly to the apical margin. 

 The same is seen in the female but to a much less marked extent. 



A. Putzeysii, n. sp. — Oblong oval, piceous, surface feebly bronzed. Head 

 smooth, frontal impressions moderate. Antennfe pale rufous. Thorax one- 

 half broader than long, apex very feebly emarginate, anterior angles broadly 

 rounded, sides moderately arcuate in front, slightly sinuous and feebly narrowed 

 to the base, hind angles rectangular and slightly prominent, base truncate, 

 basal impressions deep, the outer limited by an obtuse carina extending one- 

 fourth the length of thorax, inner impression rounded, disc of thorax moder- 

 ately convex, median line moderately impressed, surface smooth, basal third 

 coarsely punctured, punctures sparser at middle. Elytra oval, slightlj' broader 

 than the thorax, surface moderately deeply striate, (less deeply at apex) strise 

 crenato-punctate, punctures gradually finer and more distant toward apex. 

 Scutellar stria long. Intervals flat. Body beneath and legs piceous, shining. 

 Pro-, raeso- and metasterna at sides, also the parapleurae of the sterna, coarsely 

 punctured. Abdomen moderately coarsely punctured at the sides especially 

 segments one and two. Length .32 inchj 8 mm. 



One specimen, % , sent by Mr. Putzeys to Dr. Leconte, labelled St. 

 Pierre Miquelon, (Newfoundland.) 



The characters giveu in the synoptic table will enable this species 

 to be readily recognized. 



I take great pleasure in affixing to this species the name of an 

 entomologist whose labors have always produced good results and 

 whose kind reception and instruction will long be remembered by 

 myself. 



ANISODACTYIiUS, Dej. 



The large black Anisodactyli so abundant in California and Oregon 

 have been deemed troublesome to distinguish and all cabinets appear 

 to be in confusion on the subject. They appear to be separable by 

 well defined and easily seen characters. The following table is the 

 result of their study : 



Intercoxal process and middle of second and third abdominal segments punc- 

 tured; punctures with short setae. Metasternum in front and behind punc- 

 tured. 

 Thorax feebly narrowed posteriorly, basal imiDressions very feeble, surface 



entirely punctured seuiipuuetsitus. 



Intercoxal process and metasternum smooth. 



Thorax with broad but very shallow basal impression; elytra broad, sides 



very distinctly arcuate coiii^obriiius. 



Thorax with rather deep linear basal impression, surface of prothorax 

 much less densely punctured than either of the preceding species. 



califbruicus.
