In its rather variable hue, as well as in the enormous punctures of 

 its elytra, this Metophthalmus is nearly coincident with the M. encaus- 

 tus ; and indeed it may properly be regarded as the Madeiran repre- 

 sentative of that species. Although thus far agreeing with it, how- 

 ever, I am satisfied that the two are perfectly distinct. Thus, the 

 M. sculpturatus is very conspicuously smaller than its Canarian ally, 

 and also just perceptibly less ovate (or more parallel), its prothorax is 

 considerably less flattened- outwards (or expanded) at the sides, and 

 its shoulders are less acute. It was detected, in abundance, by the 

 late Mr. Bewicke in Madeira proper, under the dry, loosened bark 

 of plane-trees (at the Palheiro) on the mountains above JFunchal. 



Metophthalmus exiguus. 



M. prsecedentibus multo minor, angustulus, ovalis, omnino ferrugi-

Metophthalmus exiguus, Wott., Ann. Nat. Hist. v. 261 (1860). 

 Habitat Maderam, a Dom. Bewicke in inferioribus semel lectus. 



This diminutive Metophthalmus differs from all the preceding ones 

 in its very small size and comparatively narrow and more or less 

 oval (or elliptic) outline, as well as in its elytra! sculpture being 

 comparatively fine, with the alternate interstices less raised. In 

 colour it seems to be entirely ferruginous, judging at least from 

 the only example which has been brought to light, and which was 

 captured in Madeira proper by the late Mr. Bewicke, amongst 

 Euphorbia-refuse which he had brought from Porto Novo in the 

 east of the island. It is probable therefore that the species is of 

 Euphorbia-infesting habits; though, at the same time, it is un- 

 doubtedly possible that the presence of Mr. Bewicke's specimen in 

 that particular spot may have been merely accidental.
