9. At genius hirsutus. 



Atcenius hirsutus, Horn, Trans. Am. Ent. Soc. 1871, p. 288 \ 



Hdb. North America, Arizona 1 . — Mexico, Pinos Altos in Chihuahua (Buchan- 

 Eepbum), Presidio (Forrer). 



Taken in abundance by Forrer. His specimens agree perfectly with Horn's descrip- 

 tion, and vary very little. 



10. Atasnius setiger. 



Oblongus, niger, nitidus, thoracis elytrorumque lateribus rufo-castaneis pedibusque piceo-rufis, elytris griseo- 

 setosis ; eapite mediocriter convexo, subtiliter transversim granulato-rugoso, clypeo sat anguste sinuato, 

 angulis subacutis : thorace disco anteriore excepto grosse sparsim punctato et subtilissime punctulato, angulis 

 posticis retundatis ; scutello lsevi ; elytris profunde crenato-striatis, striis versus apicem magis exaratis et 

 fundo transversim punctatis, interstitiis subplanis, lsevibus ; ventro lsevi, lateribus baud profunde sparsim 

 punctatis. 



Long. 3|-4| millim. 



Bab. Mexico, Chilpancingo, Cuernavaca, Acapulco (Edge). 



I can detect very little difference of form which can be supposed to be sexual. The hind 

 angles of the thorax are in all examples rounded. The erect grey bristles of the elytra 

 are numerous only over the apical half. The species comes nearest to A. hirsutus, Horn, 

 the emargination of the clypeus and the distinct angle on each side being very similar 

 in both ; but the head and thorax are much more sparsely and finely sculptured. 



11. AtaBnius limbatus. 



A. strigato brevior et convexior prsecipue elytris mox a basi couvexis ; nigro-piceus, nitidus, calvus, thoracis ely- 

 trorumque lateribus indefinite castaneo-rufis ; eapite lsevi vel subtilissime punctulato, clypeo medio anguste 

 et sat profunde sinuato, extus valde rotundato ; thorace grosse irregulariter punctato, angulis posticis valde 

 obtusis ; elytris fortiter striatis, striis in fundo punctulatis, interstitiis convexis, lsevibus, versus apicem 

 angustis ibique l°-4 m elongatis, 5°-6° abbreviatis; corpore subtus glabro, abdomine toto punctato, mesosterno 

 opaco. 



Long. 4| millim. 



Bab. Mexico, Presidio (Forrer). 



Agrees with the preceding in the castaneous borders of the thorax and elytra; but 

 perfectly glabrous, and the clypeus differing in the sides of the emargination being very 

 obtusely rounded, not angulated. 



12. Atasnius capitosus.
