2. Proculus opacipennis. 



Passalus opacipennis, Thomson, Archiv Ent. i. p. 420, t. 21. f. 4\ 

 Proculus opacipennis, Kaup, Monogr. der Passal. p. 68, t. 5. f. 3. 



Hab. Guatemala \ Coban, Senahu (Champion). 



3. Proculus mniszeclii. 



Passalus goryi, Thomson, Archiv Ent. i. p. 421 (nee Melly) \ 



Proculus mniszechi, Kaup, Harold's Col. Hefte, iv. p. 11 ; id. Monogr. der Passal. p. 67, t. 5. f. 2 2 . 



Hab. British Honduras, E. Sarstoon (Blancaneausc) ; Guatemala 1 2 (Salle), Sabo, 

 Tactic, and elsewhere in Alta Vera Paz (Champion). 



B. Antennal leaflets moderately elongated. 



PROCULEJUS. 



Proculejus, Kanp, Monogr. der Passal. p. 60. 



Kaup gives the antennal leaflets as " short." They are certainly much shorter than 

 in Proculus, but not so short as in the restricted genus Passalus and its allies. The first 

 and second leaflets are more than twice the length of the body of the joints, and the 

 third leaflet is moderately slender. 



The leaflets have an extremely finely-shagreened sensitive surface and short pubes- 

 cence ; in Proculus the surface is sparsely punctured and shining, and the pubescence 

 very long. 



Five species have been described, four from Mexico and one from Ecuador. 



§ 1. Marginal interstices of the elytra more or less punctulate and hairy. 



1. Proculejus brevis. 



Passalus brevis, Truqui, Eev. & Mag. Zool. 1857, p. 263 \ 

 ? Proculejus brevis, Kaup, Monogr. der Passal. p. 61 2 . 



Hab. Mexico 1 , Jacale (Salle), Jalapa (Hoge), Mirador 2 (Dr. Sartorius). 



Kaup's P. brevis is cited with doubt, as he says the mandibles have three apical teeth. 

 M. Salle's specimens from Jacale, the locality whence came M. Truqui's types, have only 

 two apical teeth. 



2. Proculejus hirtus. 



Passalus Hrtus, Truqui, Rev. & Mag. Zool. 1857, p. 264 \ 

 Proculejus hirlus, Kaup, Monogr. der Passal. p. 62 2 . 



Hab. Mexico x (Salle), Huachinango 2 (coll. Mniszech).
