TRIBE VII — ZOPHEBINI. 



Mentum large, barely concealing ligula and maxillae, inserted on a broad short gnlar 

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

 widely separated. Tibial spurs very minute. Eyes very finely granulate. Body elon- 

 gate, apterous and covered with asperities. 



Four genera are comprised in this tribe: — 

 Tarsi sulcate; ligula concealed. 



Antennae received in deep grooves. 



Joints 9—11, connate, truncate at tip. zopherus. 



" 10-11, " , pointed " " phi/eodes. 



Antennal cavities obsolete behind, antenna) as in Phlceodes. noserus. 



Tarsi not sulcate ; eyes prominent, antennae not received in grooves. 



Antennae with joint 10 broader than 9 and 11, and free. PHELLOPSIS.

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

 family, and present well defined specific differences among themselves. 

 Six species arc known to inhabit our Territories — 

 Elytra quadritubcrculate at apex. 

 Elytra bituberculate at apex. 



Body above with, narrow white marginal band from anterior 



angle of thorax to apex of elytra. 

 Body above entirely black. 



Elytra with smooth elevated tubercles. 



Tubercles round, very convex, approximate and shining, c o n c o 1 o r . 

 Tubercles round, flattened, distant and subopaque. guttulatus. 



Tubercles elongate, flattened, moderately shining. t r i s t i s . 



Elytra finely granulate, opaque. o p a c u s . 



Elytra finely punctured, moderately shining. gracilis. 



Z. no dulosus, Sol.,* Ann. Ent. Soo. Franco V — 42. Texas. 



* Since this paper lias boon placed in the hands of the Society for publication, I have been informed by letter 

 from M. A. Salle, of Paris, that our common Texan species quoted in all American authors as Z. nodulosus, Sol., is 

 not that species, and should receive another name. In a monograph of all the species of Zopherus, prepared but still 

 unpublished, Salle proposes to call it Haldemani. A true specimen of nodulosus, Sol., is now before me, having 

 been sent me by Salli:, to whom the type was accessible. Nodulosus is more elongate, less robust 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 tho sutural row are small, elongate oval, distant and not confluent
