CYPHEROTYLUS. 105 



6. Cypherotylus 



Hob. Nicaragua, Chontales [Belt). 



An imperfect example of a distinct species allied to the Brazilian C. apiatus, but 

 with the breast and the middle of the femora and a line on each side of the thorax 

 reddish-yellow. 



Section III. Elytra evenly convex, the suture not keeled. 



7. Cypherotylus vicinus. (Tab. v. fig. 24, <j .) 



Erotylus vicinus, Guerin-Menev. Rev. Zool. 1841, p. 116 1 ; Lac. Monogr. Erotyl. p. 465 2 . 

 Cypherotylus vicinus, Crotch, Cist. Ent. i. p. 539 3 . 

 Erotylus melano stigma, Lac. loc. cit. p. 466 \ 

 Cypherotylus Jansoni, Crotch, loc. cit. pp. 149 5 , 539 6 . 



Hab. Mexico x 2 3 4 , Yucatan 2 ; Guatemala 3 , Cubilguitz in Vera Paz (Champion); 

 Nicaragua, Santo Domingo in Chontales (Janson 5 6 ). 



C. jansoni, Crotch, differs in nothing from C. vicinus but in the more reduced black 

 elytral spots, which in the present species often form an interrupted oblique fascia ; 

 and both are so very nearly allied to the Colombian C. goryi that I see no more 

 important distinction than a further extension of the black fascia, so that its oblique 

 disposition is lost. They are probably only local forms of one species. 



We figure a male specimen from Cubilguitz. 



8. Cypherotylus guatemalae. (Tab. VI. fig. 6, s .) 



Cypherotylus guatemalce, Crotch, Cist. Ent. i. p. 540 \ 



" C. vicino proximus, convexior, thoracis lateribus anguste rufo-cinctis ; elytris punctis nigris multo majoribus." 

 Hob. Guatemala \ Las Mercedes, Cerro Zunil, Zapote, Mirandilla, San Geronimo, 

 Purula, Tactic, Coban, Sinanja (Champion). 



The distinguishing character of this species is the narrow lateral rufous margin of the 

 thorax. The elytra have their black markings, especially the apical one, more developed 

 than in C. vicinus ; but I do not see any difference in their convexity, and the size of 

 the black punctures is very variable. The male characters are : — the widened front 

 tarsi, thickened front femora, and pilose dot on the ventral basal segment ; the thorax 

 scarcely differs, and the front tibiae are very little bent or compressed. A few examples 

 were found in each locality. 



9. Cypherotylus costaricensis. (Tab. VI. fig. 7, <$ .) 



C. guatemalce proxime affinis, oblongus, sequaliter convexus, niger, nitidus ; elytris flavo-testaceis, basi, apice 

 maculisque duabus medianis (oblique sitis, fere confluentibus) punctisque numerosis, nigris. Long. 22 

 millim.
