Hab. Mexico, Juquila (Salle). 



Eight examples. A very distinct species, the somewhat tumid ascendent mesosternal 

 epimera of which alone justify its being included in Strigoderma. The striae, except 

 on the sides where they are sunk in two broad furrows, are regular, and the humeral 

 callus is feebly developed, as in S. sulcipennis.

Hab. Mexico 1 , Ventanas (Forrer), Cordova, Puebla, Guanajuato (Salle), Vera Cruz, 

 Oaxaca (Salle, Hoge), Jalapa, Durango city, Guadalajara, Atlisco, Iguala, Misantla, 

 Mexico city, Cuernavaca, Matamoros Izucar, Tapachula in Chiapas (Hoge), Mochitlan 

 in Guerrero (Baron) ; Guatemala (Salle), near the city, Duefias, Chacoj, Panzos, San 

 Geronimo, El Jicaro (Champion) ; Nicaragua, Chontales (Belt, Janson). 



Varies greatly in size (from 7-15 millim.) and in colour, the elytra being sometimes 

 blackish and sometimes tawny-brown, and the thorax black or coppery-black, and uni- 

 colorous or the sides broadly bright red or yellow or rich golden, in rare examples (two 

 from Guatemala) the whole surface gilded yellow. The punctuation and hairiness of the 

 thorax also varies. None of these colour-variations appear to be local ; most of them 

 occur together in all localities whence we have received the species in numbers. A 

 widely distributed and abundant insect in Mexico and Guatemala, but becoming rarer 

 southwards.
