SPURITJS. — POPILITJS. 11 



SPURIUS. 



Spurius, Kaup, Monogr. der Passal. p. 75. 



The following is the only species known of this well-marked genus. 



1. Spurius bicornis. 



Passalus bicornis, Truqui, Rev. et Mag. Zool. 1857, p. 317 \ 

 Spurius bicornis, Kaup, Monogr. der Passal. p. 75, t. 4. f . 2 2 . 



Hab. Mexico 1 2 , Cordova (Salle), Jalapa (Hbge) ; British Honduras, R. Sarstoon 

 (Blancaneaux) ; Guatemala, Escuintla, Coban (Champion). 



POPILIUS. 



Popilius, Kaup, Monogr. der Passal. p. 75. 



Kaup enumerates five species under this genus, all from Mexico and Colombia. It is 

 distinguished by its rather broad flattened clypeus, separated from the front by a fine or 

 shallow (sometimes indistinct) line, having a tubercle at each end only; and by the 

 oblique frontal declivity of the tubercle of the vertex, from the bottom of which spring 

 the frontal carinas . 



The antennal leaflets are moderately elongated, and the genus is not widely distinct 

 from Soranus of the subsection B. 



1. Popilius klingelhoferi. 



Oileus klingelhofferi, Kaup, Harold's Col. Hefte, v. p. 5. 

 Popilius klingelhoferi, Kaup, Monogr. der Passal. p. 76 1 . 



Hob. Mexico 1 . 



2. Popilius mysticus. 



Sat angustus, mediocriter depressus ; tuberculo verticis compresso, tuberculis basalibus latissimis antice verti- 

 calibus ; carinis frontalibus apud tuberculi verticis basin baud orientibus sed per lineam longitudinalem 

 conjunctis ; thorace margine antico utrinque prope angulum sinuato (sed angulis baud acutis), sulculo 

 anteriori dilatato et punctato, lateribus medio plus minusve punctatis ; elytris punctato-striatis, interstitiis 

 mediocriter convexis : metasterno basi et vitta lata lateral! depressa, punctato-rugosis, apice utrinque punctis 

 majoribus paucis vel nullis; tibiis intermediis unispinosis carinaque superiori gradatim elevata ciliata. 



Long. 25 millim. ; tborax 6, elytra 15 millim. long. 



Hab. Guatemala, Cubilguitz 1000 feet (Champion), Yzabal (Salle). 



Apparently very closely allied to P. klingelhoferi. Kaup, however, does not mention 

 in his description of that species the remarkable position of the frontal carinae : these 

 instead of originating at the apex of the central tubercle (which in P. mysticus is almost 

 vertical, and on nearly the same level as its broad flanking tubercles) commence lower
