216 CANARIAN COLEOPTERA. 



which I possess two Sicilian siiecimens) in being a little smaller, nar- 

 rower, and more shining, — its entire surface (which is studded with 

 longer, more erect, and paler hairs) being less sculptured. Indeed its 

 prothorax (which is more cyhndric, being much less widened, or mar- 

 gined, at the hinder angles) is almost free from punctures, whilst its 

 elytra are less densely (though perhaps even more roughly) rugulose. 

 Its head is usually, like the prothorax, of a light red (being rarely 

 somewhat darkened behind) ; its antennae (instead of being black) 

 are of a pale rufous-brown ; and its tibise and tarsi are more brightly 

 testaceous. It is of the greatest rarity, — the only specimens which 

 I have seen (seven in number) having been captured by myself, in 

 the Rio Palmas of Fuerteventura, at the beginning of April 1859, by 

 brushing the Arundo donax in swampy spots alongside the stream. 

 I believe that they are all of them males. 



Fam. 35. TELEPHORID^. 



As the members of the present and following two families (MaJa- 

 cJiildce and Meh/ridce) formed the subjects of a lengthened Paper "on 

 the Canarian Malacoderms," published by myself in the first volume 

 of the ' Journ. of Ent.' in 1862, I must refer to that memoir for the 

 actual descriptions of the several species. Nevertheless, since (as in 

 the analogous case of the CalatJii) the diagnostic, and other, observa- 

 tions which it will be desirable here to add can scarcely be compressed 

 into less space than that which I there devoted to them, I shall in 

 the present re-enumeration extract such of them, verhatim, as appear 

 necessary to impart the information required. Two additions, how- 

 ever, and some fresh loccdities, the result of Dr. Crotch's late re- 

 searches in the islands, will render occasional alterations necessary. 



Genus 143. MALTHINUS.

 Habitat insulas omnes Canarienses, ad flores, frequens. 

 The present Malthinus may be regarded as the representative in 

 these' islands of the European M. JJaveolus. It is, however, on the 

 average considerably smaller than that insect (descending to a com- 

 paratively minute size) ; its limbs and elytra are relatively shorter ; 

 its head, although greatly narrowed, is not quite so attenuated pos-
