CANARTAN COLEOPTERA. 237 



copperj'' hue of its head and prothorax, and by its cyaneous elytra. 

 So far as observed hitherto, it appears to be confined to Lanzarote 

 and Puerteventura ; and in its habits it is (for a Corynetes) exceed- 

 ingly anomalous, for I have never yet captured it except in the dung 

 of cattle (horses, oxen, camels, (fee.) in the open country. But in 

 such situations it is far from uncommon during the spring months 

 (in company with the Notiomimus Jhnicola and various Saprini and 

 Aphodii), preferring the driest and most barren spots. In Lanza- 

 rote it was found also by Mr. Gray.

Habitat in sylvaticis subeditioribiis humidis Teneriffie, rarissimus. 



I do not think it necessary to give any lengthened details (dia- 

 gnostic or critical) respecting the members of the present Family here 

 enumerated, having fuUy done so (both as to genera and species) in 

 my Paper on the " Ptinida; of the Canary Islands " which has lately 

 been published in the ' Trans, of the Ent. Soc. of London.' I must 

 therefore refer the reader, for all minute particulars, to that Memoir. 



The large and posteriorly-acuminated C. Bonvouloirii appears to be 

 confined to the damp sylvan regions of a rather high elevation, in 

 Teneriffe, my specimens being from the mountain -district of the Agua 

 Mansa. It is evidently both local and rare. It was found also, though 

 sparingly, by Dr. Crotch. 



37(3. Casopus dilaticollis. 



Casapus dilaticollis, WuU., Trans. Ent. Soc. Lond. (3rd series) i. 197 

 (1862). 



Habitat Teneriffam et Gomeram, in locis inferioribus necnon inter- 

 mediis (pra3sertim illis) degens. 



Whilst the C. Bonvouhirii is confined to the damp sylvan districts 

 of a rather high elevation, in Teneriffe, the present species (which, 

 inier alia, has its prothorax much dilated anteriorly) descends to the 

 sea-level, — the upper limit of its range scarcely reaching the lower 

 one of that insect. Indeed the examples from the intermediate dis- 

 tricts (Taganana, Las Mercedes, Souzal, (fee.) are less typical than those
