or feeblj' arcuate 5 



5 — Larger species, seldom at all under 3 mm . in length 6 



Small species, always under 3 mm. in length 7 



6 — Prothorax short, one-half or more wider than long. 

 Sides of the prothorax parallel. 



Prothorax distinctly less than twice as wide as long. 



The sides evenly and very feebly arcuate; elytral pubescence rather 



long and dense 5. fratei'iilis 



The sides evenly and less feeljlj- arcuate; elytral pubescence very sliort 



and much more sparse ( aicr Bland ) 6. cyliiidricus 



The sides evenly and very strongly arcuate; elytral pulicscence rather 



short and only moderately dense 7. laticollis 



The sides Ijroadly subangulate behind the middle; pubescence con- 

 spicuous 8. ca^^tus 



The sides broadly and strongly sinuate in apical half 9. siiiliosus 



Prothorax very nearly twice as wide as long 10. traiisversus 



Sides of the prothorax slightly convergent, the apex somewhat narrower 

 than the base; l)ody strongly con\ex and very sparsely pubescent. 

 Prothorax feebly narrowed anteriorly, widest at or near the base; an- 

 tennae rapidly incrassate toward tip 11. sparsiis 



Prothorax less transverse, more strongly narrowed anteriorly, widest dis- 

 tinctly before the base ; auteunte scarcely at all incrassate.. 12. ciliatiiK 

 Prothorax much less transverse, the sides feeblj' convergent from base to apex 

 and just visibly, evenly arcuate; vestiture coarse but very short, easily 



denuded 13. atricornis 



T — Sides of the prothorax parallel or very nearly so. 



Body narrow and elongate, the elytral vestiture rather dense; thoracic cilia 



shorter and timbriform 14. fulvotarsis 



Body stouter, densely pubescent; thoracic cilia longer... 15. aiiteiiiiatus 

 Body shorter, the vestiture sparse; thoracic cilia long and not timbriform. 



Elytral punctures fine 16. discipiiliis 



Elytral punctures coarse 17. feiuoralis 



Sides of the prothorax convergent from near the base; body somewhat as in 

 Listrus, but with the anterior tibiae strongly spinose and the sides of the 



prothorax devoid of serrulation 8 



S — Pronotum shining and sparsely punctate; legs clear rufous throughout 9 



Pronotum densely sculptured 12 



O — Body stout ; elytral punctures sparse 10 



Body less stout, the elytral punctures close-set 11 



lO — Elytral pubescence very coarse 18. griseilS

Punctures of the pronotum tine tluougliout; marginal cilia of the elytra 



long, slender and erect 19. $«iinilluii<ii 



Punctures coarser, especially toward the sides; elytral cilia sliort, coarse 

 and recurved 20. iiiode^tii*:)
