504 CANARIAN COLEOPTEEA. 



liarities being more expressed ; in its clypeus being less straightly, 

 and less widely, truncated at the apex, as well as more rounded-off 

 (or less prominent) in front of either eye ; in the hinder angles of 

 its prothorax being still more obtuse (the sides not being at all si- 

 nuated immediately before them); and in its limbs being both shorter 

 and more rufescent.

This appears to be the most widely spread of the Canarian mem- 

 bers of the genus, and by far the most variable — ^having a slightly 

 different phasis for nearly every district in which it occurs. It will 

 probably be found to be nniversal throughout the central and western 

 portions of the archipelago, though hitherto I have observed it only 

 in Grand Canary, Teneiiffe, Palma, and Hierro, — namely, in the re- 

 gion of El Monte, of the first ; around Orotava, the Agua Mansa, 

 Ycod el Alto, the Agua Garcia, Taganana, and Las Mercedes, of the 

 second ; just below the Cumbre above Buenavista, of the third ; and 

 near Yalverde, of the fourth. In Teneriffe it was taken likewise by 

 Dr. Crotch and the Barao do Castello de Paiva. 



The larger state (a), which may possibly be distinct specifically, 

 of the H. congener has a certain aifinity with the Madeiran H. Vul- 

 canus, whilst the smaller ones are still more evidently allied to the
