Eab. Mexico 1 , Cordova, Tuxtla, Vera Cruz (Salle), Jalapa, Misantla, Tapachula in 

 Chiapas (Edge); Guatemala (Salle), Zapote, San Isidro, Escuintla, El Eeposo (Cham- 

 pion) ; Nicaragua, Chon tales (Belt, Janson), San Lorenzo (Janson) ; Costa Rica ( Van 

 Patten, Sogers) ; Panama, Volcan de Chiriqui (Champion). 



Distinguished by its very elongate-ovate form ; the elytra gradually flattened behind, 

 with long and sharp sutural spine, and the thickened reflexed lateral margins 

 continued nearly to the apex. In Mexico and Guatemala the colour is almost always 

 testaceous-yellow, with strong brassy or golden reflections, but some Guatemalan 

 examples are rich dark coppery with brassy-green reflections. The legs are coppery 

 or reddish, with brassy femora. An example from Cordova is figured. In the southern 

 parts of our region, according to the few examples received, the species is represented 

 by a tolerably well-marked local variety : — 



Var. P. alutacea. Caput et thorax densius punctata hoc punctis minutis intermixtis, versus latera punctulato- 



alutaceo, subopaco ; corpore subtus cum pedibus suturatius viridi-seneo, pedibus nigris vel piceis. 

 Long. 27-30 inillim. 



Eab. Costa Eica (Van Patten); Panama, near the city (J. J. Walker), Volcan de 

 Chiriqui (Champion), Chiriqui (Bible). 



9. Pelidnota punctulata. (Tab. XVI. fig. 7.) 



Elongato-oblonga vix ovata, capite thoraceque fusco-seneis, hoc lateribus clypeo et elytris fuscescenti-ochraceis, 

 subtus obscure viridi-eenea, punctulato-alutacea, pedibus obscure testaceo-rufis seneo-tinctis ; capite et 

 thorace subconfluenter punctulatis hoc medio vel paullo- post medium latiore, sulculo marginali basi 

 indistincte impresso; elytris striato-punctulatis, interdum medio confuse punctatis, margine laterali 

 incrassato mox pone medium terminata, apice suturali spinoso. Mesosterni processus brevis, conicus. 

 Clypeus apice, <$ minus $ magis et angustius, productus obtusus reflexus. Pygidium <S $ lateraliter
