NORTH OF MEXICO. 27] 



TRIBE VII — ZOPHERINT. 



Mriitiini large, barely concealing ligula and maxillae, inserted on a broad short gular 

 process. Middle coxae entirely enclosed by sterna, without trochantin. Anterior coxa? 

 widely separated. 'Tibial spurs very minute. Eyes verj finely granulate. Bodj elon- 

 gate, apterous and covered with asperities. 

 Four genera are comprised in this tribe: — 

 Tarsi sulcate ; ligula concealed. 



Antenna' received in deep grooves. 



Joints 9—1 1. connate, truncate at tip. ZOPHERUS. 



" 10—11, " , pointed " " I'HUEODES. 



Antenna! cavities obsolete behind, antenna' as in Phlceodes. noserus. 



Tarsi not sulcate; eyes prominent, antenna' not received in groove-. 



Antenna' with joint K) broader than !) and 11, and tree. PHELLOPSIS. 



ZOPHERUS, /<<■ Cast. 

 Zopherus, Cast., Hi-t. Nat. In-.. Col. I!.].. ! 



The Zopheri are much more convex than the species of the other genera of this sub- 

 family, and present well defined specific differences among themsehe-. 

 Six species are known to inhabit our Territories — 

 Elytra quadrituberculate at apex. nodulosus. 



Elytra bituberculate at apex. 



Bodj above with narrow white marginal baud from anterior 



angle of thorax to apex of elytra. elegans. 



Body above entirely black. 



Elytra with smooth elevated tubercle-. 



Tubercle- round, very convex, approximate and shining, c o n c o lor. 

 Tubercle- round, flattened, distant and subopaque. guttulatus. 



Tubercle- elongate, flattened, moderate!] shining. t r i s t i s . 



Elytra finelj granulate, opaque. opacu-. 



Elytra finely punctured, moderately shining. gracilis.

• Since this paper has been placed in the hands of the Society for publication, I have been informed by letter 

 from M. A. --.ill . of Paris, that our common Texan sp< cies quoted in all American authors a- '/.. Sol., i- 



not that species, ami should receive another nam.'. In a monograph of all tin- species of Zopherus, prepared but -till 

 unpublished, Sall6 proposes to call it Baldemani. A true specimen of , Sol., is now before me, having 



been sent me by Salle, to whom tin- type was accessible. \ m ilongate, less r"l.u-t and rather less con- 



vex. The black spots of the thorax are more numerous and cover a larger space without becoming confluent into a 

 large patch, as in haldemani. The black spots of the Rutural row are small, elongate oval, distant and not confluent
