428 Mr, T. V. Wollaston on the Canarian Malacoderms. 



(or galeiform), and internally-pectinated lobe. In 3 out of the 16 

 species described below (namely, the A. comnilxtus, IcevicoUis, and 

 posticus), I have not yet captured the males ; but I believe, never- 

 theless, that they are strictly members of this genus.

The present Attains and the following one are the universal species 

 of Teneriffe, occurring on flowers from the sea-level to an elevation 

 of at least 8000 feet. The A. rujicollis may be known by its bright- 

 red prothorax, which is usually quite immaculate. The specimens 

 from the higher altitudes are generally a little more densely punc- 

 tured and ajnescent, and have their minute under--^i\e (of short, 

 decumbent, subcinereous hairs) more evidently developed ; but they 

 merge gradually into the others as we descend into the lower 

 districts, and have no character sufficiently constant to warrant the 

 suspicion that they are distinct. The " var. /3 " appears to be only 

 a small state peculiar to Palma, in which the tibise and tarsi and 

 the base of the antennae have a tendency to be testaceous : I captured 

 it high up in the Barranco da Agua, as also in the Barranco de Galga, 

 and (in a state approaching nearer to the TeneiiiFan one) at the 

 Banda. In Teneriffe it seems to occur universally : my specimens 

 are chiefly from the neighbourhoods of S*^ Cruz, Orotava and Laguna, 

 from Taganana, Souzal, the Agua Garcia, the Agua Mansa, Yeod el 

 Alto, and (from oif the blossoms of the Spartium nuhigena) on the 

 two lofty Cumbres — above the Agua Mansa, and adjoining the 

 Canadas. Near S*'' Cruz it was taken also by Mr. Gray and the 

 Barao do CasteUo de Paiva.
