of S. quadrivittatus, but as Salle's specimens must have come from the same 



jre is little doubt about the determination. The above description of the 



source there is little 



sexual characters is taken from the series obtained 



are three males. 



Truqui, amongst which ther 



18. Sphenophorus lineatus, sp. n. (Tab. VIII. fig. 7, s .) 



Very Hke S. quadrivittatus, black beneath, ferruginous above, the prothorax with three vittse on the disc, and 

 the elytra sometimes with the alternate dorsal interstices, infuscate or black ; the legs ferruginous, the 

 femora striped or maculate with black. Rostrum moderately stout, feebly curved, almost smooth, 

 angulate at the apex beneath (as seen in profile), feebly dilated just before the base, foveate 

 between the eyes, the basal portion not sulcate. Prothorax as in S. quadrivittatus, the elytra more 

 coarsely crenate-striate, with feebly convex interstices. Pygidium with the depressed spaces at the apex 

 still more coarsely punctate. Femora almost smooth, the anterior and intermediate pairs in both sexes 

 with a small pencil of hairs at the base similar to that on the coxae. Ventral excavation of the <5 very 

 long and deep, almost smooth ; the fifth segment in both sexes transversely depressed at the tip and 

 coarsely punctured throughout, the other segments similarly punctate laterally. 



Length 7^-9, breadth 2|-3§ millim. ( tf $ .) 



Bob. Mexico, Amula in Guerrero 6000 feet (II. H. Smith). 



Three males and one female. The non-sulcate, coarsely punctate fifth ventral 

 segment, and the very small tuft of hair on the anterior and intermediate femora and 

 coxse, in the male, and the coarsely punctured fifth ventral segment in the female, 

 distinguish S. lineatus from S. quadrivittatus. The allied S. -American S. brunnei- 

 jpennis, Germ, (signaticollis, GylL), has a longer and more coarsely punctured area on 

 the disc of the prothorax, the anterior and intermediate femora fringed with short hairs 

 beneath, the pygidium convex, &c. 



19. Sphenophorus imus.

$ . All the femora along their lower face, a large patch on the anterior coxse, a smaller one on the inter- 

 mediate coxae, and a rather broad space down the middle of the fifth ventral segment, clothed with short, 

 decumbent, ochreous hairs ; tibiae ciliate within ; ventral excavation long and deep, closely punctate. 



§ . Anterior and intermediate femora with a few hairs at the base, and the coxae of the same legs each with 

 a small tuft ; tibiae fringed with shorter hairs. 



Var. The prothorax with four narrow vittae, and the elytra with the alternate interstices, rufescent.
