86 LAMELLICORNIA. 



B. Apical seta? of the hind tibiae unequal in length. 

 a. Base of the thorax margined. 



12. Aphodius flohri. 



Elongato-oblongus, convexus, niger, politus, capitis margine tarsisque (interdum pedibus totis) piceo-rufis, 

 antennis fulvis ; capite semicirculari, clypeo antice emarginato et utrinque distincte angulato, genis haud 

 rotundatis; fronte <$ grosse rugose, $ subtiliter sparsim, punctata, media tumidula, carinulaque utrinque 

 ante oculum : tborace basi subtiliter marginata, angulis posticis valde obtusis ibique nee sinuato, dorso 

 mediocriter dense punctato punctisque minutis intermixtis, linea dorsali laavi ; elytris relative elongatis, 

 exarato-striatis, striis punctulatis parum crenulatis, interstitiis planis subtiliter sparsim punctulatis ; meso- 

 sterno grosse oblongo-punctato, metasterno utrinque linea uuica punctorum. 



Long. 6-7 millim. 



Hab. Mexico, near the city (Flohr, Edge), Guanajuato, Oaxaca (Salle), Durango 

 city, Eefugio (Edge). 



This species seems to be closely allied to A. coloradensis, Horn. 



13. Aphodius ? 



Eab. Mexico, Northern Sonora (Morrison). 



A species sent by the late Mr. Morrison as the A. ursinus, Motsch., an insect known 

 previously only from Alaska and Kamchatka, and, according to Von Harold and Dr. 

 Horn, belonging to the section having equal apical seta? to the hind tibiae. Morrison's 

 species certainly agrees very well with the descriptions of both authors, with the excep- 

 tion that the apical setse are decidedly unequal; hence I hesitate to adopt the name. 

 It is closely allied to A. flohri. 



14. Aphodius glyptus. (Tab. VI. iig. 12.) 



A. stwpido (Horn) proxime affinis. Mger, subopacus, supra setis brevissimis argenteo-griseis dense obsitus ; 

 capite toto subdense subtiliter punctulato ; clypeo sinuato et, extus subangulatim rotundato, margine ante 

 genas perparum sinuato ; fronte media convexa ; tborace creberrime hie illic confluenter et tequaliter 

 punctulato, basi utrinque late sinuata angulisque obliquis obtusis ; elytris exarato-striatis, striis nitidis, 

 fere lsevibus, interstitiis usque ad apicem planis et subtiliter complicato-reticulatis ; antennarum clava 

 fusco-nigra.

15. Aphodius latecrenatus. (Tab. VI. fig. 13.) 



A. stupiclo (Horn) affinis. Obscure castaneo-fuscus, subopacus, capitis thoracisque lateribus plus minnsve 

 castaueo-rufis, elytris obscure rufo-maculatis ; capite toto fere aequaliter discrete punctulato, inermi ; clypeo 

 medio convexo, antice subsiuuatim truncato, lateribus usque ad genarum apicem leviter sinuatis subrectis ; 

 tborace confertissime fere reticulatim punctato, punctulis minutis dorsi intermixtis, lateribus sicut corrosis, 

 angulis posticis valde sinuatis ; elytris latissime exarato-striatis striisque grosse et late confertissime 

 punctatis, interstitiis crebre punctatis, incumbente pubescentibus. 



Long. 3|-5 millim. 



Hab. Guatemala, Totonicapam 9000 to 10,500 feet (Champion).
