14 PECTLNICOKNIA. 



PAXILLUS. 



Paxillus, MacLeay, Horse Entom. i. p. 105 ; Kaup, Monogr. der Passal. p. 80. 



Two species are known, both widely distributed in Tropical and Subtropical America. 



1. Paxillus leachi. 



Paxillus Leachii, MacLeay, loc. cit. p. 106 ; Kaup, loc. cit. p. 80. 

 Passalus Leachii, Percheron, Monogr. des Passales, p. 37, t. 3. f. 2. 



Hab. Mexico, Cordova, Orizaba, Tux tla (Salle), Jalapa (Edge); British Honduras, 

 Belize (Blaneaneaux) ; Guatemala, Capetillo, Zapote, San Isidro, Las Mercedes, 

 Mirandilla, Calderas, Panima, Chacoj, Cubilguitz, Cahabon, Teleman (Champion); 

 Nicaragua, Granada (Salle), Chontales (Belt, Janson) ; Panama, Bugaba (Champion). — 

 South America to South Brazil. 



NELEUS. 

 Neleus, Kaup, Monogr. der Passal. p. 85. 

 Ninus, Kaup, loc. cit. p. 89. 



The characters given by Kaup as distinguishing the two above-named genera are 

 evidently only of specific value : one is the free apex of the horn or tubercle of the 

 vertex in Neleus, which varies greatly, and another the median teeth of the clypeus, 

 approximated and obtuse in Neleus and widely separate and acute in Ninus. The 

 last-named character does not hold good, specimens of Neleus tlascala var. punctiger 

 having the teeth as distant and acute as in Ninus interstitialis. 



Seven species are known, distributed throughout Tropical America, north and 

 south. 



1. Helens tlascala. (Tab. I. figg. 15, 15a*.) 



Passalus tlascala, Percheron, Monogr. des Passales, p. 45, t. 3. f. 5 \ 



Hab. Mexico \ Tres Marias Islands (Forrer), Cordova, Chiapas (Salle), Jalapa (Edge) ; 

 Guatemala, Yzabal (Salle), Cerro Zunil, San Isidro, Zapote, San Geronimo, Chacoj, 

 Panzos, Lanquin (Champion) ; Nicaragua, Chontales (Belt, Janson) ; Panama, Volcan 

 de Chiriqui, Tole (Champion). — South America to South Brazil and Paraguay. 



Tar.? N. punctiger, Serv. Ene. Meth. x. p. 20'; Percheron, 1. c. p. 47, t. 3. f. 6 \ — Magis depressus, elytris 



fortius punctatis, clypeo dentibus medianis acutis distantibus. 

 Long. 30-45 millim. 



Hab. South America, Cayenne \ Amazons. 



Kaup reunited the two above-named species, whereby the older name, N punctiger, 

 was retained for the form so common in our region. Judging from Amazons examples, 

 which agree with Percheron's description of N. punctiger, for which he names Cayenne 

 as the sole locality, the two forms seem to be sufficiently distinct to be treated 

 as separate species. 



* This species is badly drawn ; the insect is much flatter than represented by our artist.
