Although in structure this species comes nearer to G. imperialis, it bears a greater 

 general resemblance to the Venezuelan and Peruvian G. cegeon ; from the latter it differs 

 in its more cinnamon-tawny hue and less distinct black suture and margins, and in the 

 form of the thoracic horn in the different developments of the male, the horn in G. cegeon 

 being strongly compressed laterally in all stages, except the somewhat dilated apex of the 

 most highly-developed individuals. The basal joint of the anterior tarsi is short (not 

 longer than the second) in G. cegeon ; the hind tarsi robust and densely hairy beneath, 

 and the mandibles narrow and bifid. A well-developed male is shown on our Plate. 



4. Golofa Championi. (Tab. XX. figg. 12, 12 a, 13, 13 a, 6 ; 14, 14 a, $ .) 



c? . Quoad corporis formam G. cegeoni similis, sed tborace fere inermi etc. valde differt. Supra fulvo-castanea, 

 thorace fusco-nigro nebuloso, elytris vage fusco-nigro vittatis sutura et margine fuscis, capite, corpora 

 subtus pedibusque fuligineo-nigris, pectore et femoribus flavo-cinereo villosis ; tborace disperse disco 

 posteriore confertim punctato, elytris irregulariter striato-punctatis. Tibiae anticae sicut in Golofis typicis 

 tridentatn, intermedin medio extus unispinosn apice extus valide bidentatn, posticn medio et apice 

 inermes ; tarsi antici articulo basali 2° dimidio longiore, postici subtus brevissimo setosi. Mandibuln 

 apice intus indentatn, interdum subfissae. 



S major. Cornu capitis mediocriter elongatum, gracile, recurvum, postice punctatum, basi et capite longe 

 pilosis. Cornu thoracis breve, compressum, acutum, oblique elevatum, antice et sulco thoracis anteriore 

 longe pilosis. 



S minor. Cornu capitis brevissimum, thorace inerme, antice medio fovea longe pilosa. 



$ . Nigra, nitida, elytris fere sicut in G. pizarro $ dense punctatis, clypeo magis elongato ; subtus dense 

 vulpino-rufo pubescens. Tibiae anticae 4-dentatn, intermedin sicut in <S , posticae medio et apice brevis- 

 sime dentatae. 



Long. 34-42 millim. c? $ . 



Eab. Guatemala, Cerro Zunil 4000 to 5000 feet (Champion). 



Fifteen examples of the two sexes. The male minor agrees in many respects with 

 the description of G. inermis, Thorns. Arcana Nat. p. 11, but the size (21-28 millim.) 

 and locality (Chili) and some minor discrepancies lead me to conclude that the species 

 are different. 



We figure a well-developed male, a male minor, and a female, all from Cerro Zunil. 



5. Golofa imbeUis. (Tab. XX. figg. 16, 16 a, tf ; 18, 18 a, $ .) 



G. cJiampioni affinis ; corpore postice magis ampliato ; omnino castaneo-nigra, $ nigra nitida, subtus corpore 



toto cum propygidio et pygidio vulpino-rufo pubescentibus; thorace sat crebre, hie illic confertim, punctato ; 



elytris sericeo-opacis subtiliter punctulatis, hie illic substriatis, versus suturam rugoso-punctatis et niti- 



dioribus. Pedes sicut in G. championi. Mandibulae apice integrae. 

 <5 major. Cornu capitis brevissimum, capite postice vulpino-piloso. Thorax nullo modo cornutus, medio antice 



leviter carinatus et juxta margin em fovea dense vulpino -pilosa. 

 c? minor. Caput unituberculatum, thoraceque antice haud carinato.
