(? ? Antennis corpore longioribns ; elytris baud mfo- 

 rittatis, suturaque pallida ; thorace disco nigro-yittato. 

 Cbontales. 



The elytra are broadly and rather obtusely truncated at 

 the apex ; the sm'face punctulated, chiefly in lines ; the 

 sides (above the epipleurre) bicarinated. The thorax is 

 considerably narrowed in front, the sides tumid, ahnost 

 tuberculated, in the middle. 



I have some doubt about the ^ here described belononng 

 to the same species ; as what I take to be the $ of the 

 slight New Granadan variety differs fr'om it considerably. 

 But I have only seen one specimen of each sex of the 

 Chontales form. 



Erana pusilla, n. sp. Xigra, griseo subtiliter pubescens, 

 et sparsim erecte pilosa ; capite, thorace antice scutelloque 

 testaceo-frih'is ; antennis filiformibus, pilosis, infi-a longe 

 sparsim ciliatis, testaceo-fidvis, scapo elongato et articulo 

 secundo nigris, cseteris apice fuscis ; pedibus flavo-testaceis, 

 tibiis intermediis et posticis apice nigris, tarsis fusco- 

 maculatis; episternis albo-tomentosis ; corpore supra, et 

 metasterno subgrosse hand dense punctatis. Long. 3 lin. 



One example. 



The same species occiu's in Mexico, as a variety, differ- 

 ino" only in the head being dusky and the thorax having a 

 laro-e fulvovis spot in the middle, instead of on the anterior 

 margin. Having only one example of each before me, it 

 cannot be decided whether this is a local form, or whether 

 (which is more probable) the colour is variable. 



The genus Erana, according to the typical species, 

 E. cincticornis, has the head retractile and the scape long 

 and rather slender ; it is, therefore wrongly defined by 

 Lacordafre, who places it in the group jErenicites, which 

 have the head exserted. Saperda triangularis, Germar, 

 must be removed fr-om the genus.
