fused as merely to impart a just perceptibly paler tint to the disk 

 of the elytra : and at first sight, therefore, they might be taken for 

 the B. manrus ; nevertheless their slightly larger size and somewhat 

 longer antenna3, in conjunction with their less shining surface and 

 less blackened tibisc and feet (the latter of which have their tarsal 

 claws almost simple internally), prevent their being confounded with 

 that species. I shonld add, however, that two examples which were 

 taken in the same island (Lanzarote) by John Gray, Esq., have their 

 discal patches well developed.

The i¥. patmelis (which is common in Porto Santo, and which 

 occurs, though very rarely, in Madeira likewise) abounds throughout 

 Lanzarote and Fuerteventura — the two eastern islands of the Cana- 

 rian archipelago ; but I have not yet observed it in any other por- 

 tions of the Group. It is found more especially in the driest regions, 

 and delights in sandy and calcareous spots. It was taken, also, in 

 Lanzarote by Mr. Gray, and in Fuerteventura by M. Hartung ; the 

 latter of whom wrongly identified it (as I can vouch from the pos- 

 session of one of his specimens) with the M. obscuror/iittatns, Dufts.

The present species and the following one are very closely allied, 

 but I believe that they are truly distinct ; and such also was the 

 opinion of Dr. Schaum. to whom I sent them for examination. They
