CANARIAN COLEOPTERA. 295 



dense obsita ; prothorace valde profunde et densissime piinctato, 

 setis apicalibus saepius distincte longioribus; elytris elongato-ovatis, 

 ad humeros vix oblique truncatis, valde profunde pnnctato-striatis 

 (punctis maximis), pone medium macula magna obluniformi (an- 

 tice, sod vix postice, plus minus obsciu-e nigro-terminata), necnon 

 nebida parva indistincta (plus minus obsoleta fractil) versus humeros 

 subcinereo-ornatis. 

 Variat fere immaculata, squamis pallidioribus plus minus obsoletis.

Habitat in Palma et Hierro, locis intermediis passim. 



In their somewhat elongate-ovate elytra, which are more gradually 

 narrowed towards the base (or less truncated, obliquely, at the shoul- 

 ders), the present species and the following one have much in com- 

 mon ; nevertheless when denuded of their scales they will be seen to 

 be abundantly distinct from each other ; for whilst the latter has its 

 striae comparative! 1/ fine and merely crenated, the E. hystrix has them 

 very deeply and regularly punctured — the punctures being of an 

 enormous size. This difference in their sculpture causes the inter- 

 stices of the crenata to be proportionally wide and flattened, whilst 

 in the hystrix they are narrower and more costate. In minor details, 

 the present insect is rather more obscurely coloured than its Tene- 

 riffan ally (the paler scales being usually less developed, and covering 

 a smaller portion of the entire surface) ; the setae with which it is 

 studded are somewhat more numerous and erect ; its rostrum is per- 

 haps a trifle longer and slenderer ; and the shape of its cloudy patches 

 is not quite the same. 



As yet I have observed the E. hystrix only in Palma and Hierro, 

 in the sylvan districts of which I took it, sparingly, during the winter 

 and spring of 1858.
