Cis Lair. 



Only those species represented before me are included in the follow- 

 ing table : — 



Elytra with shallow, variolate and nude punctures, intermingled with others smaller and 

 deeper which bear the setae 2 



Elytra deeply punctured throughout, all the punctures bearing hairs or setae 1 1 



2 — Body stout and convex, the elytra confusedly rugulose ; maxillary palpi very stout ; 

 anterior tibiae acute and feebly everted externally at tip ; apical angles of the 

 prothorax right and somewhat prominent, the apex prolonged and broadly 

 rounded over the head ; base not distinctly margined 3 



Body narrowly elongate oval and more depressed, the surface less rugose but with the 

 elytral series more distinct ; maxillary palpi variable but generally less stout ; 

 antennal club smaller, with the two basal joints wider than long ; apical angles 

 of the prothorax obtuse, the apex broadly, evenly rounded over the basal parts of 

 the head, the base finely margined ; scutellum transversely oval 8 



3 — Elytral bristles moderate in length, more or less distinctly serial in arrangement, 

 the antennal club long and loose, with the two basal joints as long as wide ; head 

 and pronotum finely, evenly punctured, the elytral punctures fine, not very dis- 

 tinct and rather sparse ; male sexual characters very feeble . , 4 



Elytral bristles extremely short, distributed uniformly but without order; antennal 

 club shorter, with the two basal joints wider than long ; male characters pro- 

 nounced 7 



4 — Third and fourth joints of the antennae elongate and equal, each as long as the 

 fifth and sixth together. Body stout, shining, castaneous in color, the head 

 moderate, with the clypeal margin feebly reflexed and broadly subtruncate ; eyes 

 rather well developed; prothorax distinctly wider than long, the sides reflexed, 

 feebly convergent and feebly, evenly arcuate from the obtuse basal angles to the 

 apex ; elytra one-half longer than wide, twice as long as the prothorax and just 

 visibly wider. Length 2.4-2.8 mm. ; width 1. 05-1. 25 mm. North Carolina 

 ( Asheville) caroling, sp. nov. 



Third joint much longer than the fourth, the latter distinctly shorter than the fifth 

 and sixth combined 5 



5 — Concave side margin of the pronotum not at all inwardly prolonged at base ; body 

 large, generally pale in color, shining; prothorax more than one-half wider than 

 long, the basal angles very obtuse and rounded ; sides slightly convergent and 

 very feebly, evenly arcuate throughout ; elytra barely one half longer than wide, 

 nearly two and one-half times as long as the prothorax and slightly wider, the 

 humeral callus small but pronounced. Length 2 8-3.0 mm. ; width 1.1-1.3111111. 



Montana (Missoula) pallens, sp. nov. 



• Concave margin more or less distinctly prolonged inwardly at base ; color black or 

 piceous-black, the size smaller 6 



6— Male with the prothorax simple throughout. Atlantic regions, from Massachusetts 

 to Iowa and Texas ( Houston) f uscipes Mell. 



Male with the prothorax broadly impressed at apex. Body moderately stout, strongly 

 convex, blackish in color and shining, the elytral punctures generally stronger
