Hab. Mexico 1 2 3 (Salle, ex coll. Sturm), Morelia in Michoacan, Tonila in Colima 

 {Edge). 



Tbe numerous examples captured by Herr Hoge vary from 9-10 millim. in length, 

 the size given by Blanchard. Two of Sturm's measure 12 millim. The series 

 examined exhibit nearly all gradations between the colour-varieties above described. 



DILOPHOCHILA. 



Corpus elongatum. Caput magnum, praecipue post oculos elongatum, latum ; oculi parvi. Clypeus antice 

 medio incisus, margine reflexo. Labrum bilobatum, porrectum, lobis ciliatis. Mentum medio dense 

 pilosum. Antennae 9-articulata3, articulis 3° et 4° elongatis cylindricis. Tarsi antici (6 2) ungue exteriore 

 elongato subgracile, valde inaequaliter fisso, dente superiore brevi tenui dorsali ; ungues intermedii simplices. 

 Elytra margine postico membranaceo. Tibiae anticae bidentatae. 



The species constituting this genus much resembles, except in its narrow oblong 

 form, the genus Bolax, from which the porrect, deeply divided labrum amply 

 distinguishes it. The clypeus is large and subquadrate, with much rounded anterior 

 angles, and separated from the forehead by a straight suture which is somewhat 

 inconspicuous owing to the dense sculpture. 



l. Dilophochila bolacoides. (Tab. XIV. fig. 25.) 



Testaceo-rufa, fronte cum vertice thoraceque viridi- vel cupreo-aeneis pilis longis obsitis, hoc margine toto 

 lineaque dorsali rufo-testaceis, elytris fulvo-testaceis pallide lineatis ; pectore fusco-aeneo; capite toto 

 creberrime confiuenter punctato ; thorace paullo ante medium angulato-dilatato, postice sinuato-angustato, 

 angulis posticis subrectis, margine acuto basali integro, supra dense inaequaliter hie illic confiuenter 

 punctato ; elytris punctato-striatis, striis partim confusis interstitiisque transversim rugulosis, 2 vel 3 

 discoidalibus plus minusve costiformibus. 6 . Ungues valde elongati. $ . Elytra margine laterali 

 medio incrassato et verticaliter longe arcuato. 



Long. 8-11 millim. S $ • 



Hab. Mexico, Parada (Salle), Las Vigas (Edge). 

 Six examples. 



Subfam. BUTELINM 



This subfamily corresponds to the " Sous-Tribu Eutelides vraies " of Lacordaire, with 

 the exception of the genera Macropoides and Heterosternus, and the greater part of his 

 Groupe "Areodides." It excludes, therefore, those genera in which the head is 

 furnished with a frontal suture. The front edge of the labrum is deflexed in the 

 middle an^ in most cases closely folded under.
