minutely granulated) throughout, whilst the elytra are shining, and 

 merely roughened in the ordinary manner. Its colour is black, 

 except the hinder part of the prothorax (which is dull yellow), and 

 the tibiae, tarsi, and base of the antennce (which arc brownish- 

 testaceous). The only two examples which I have seen (a male and 

 a female) were captured by myself in Fuerteventura — I believe in 

 the Kio Palmas, early in April of 1859.

The present Attains, which has been observed hitherto only in 

 Gomera, is, like most of the species, very variable in colour ; never- 

 theless its subopake and densely and minutely rugulose head (in 

 which respect it somewhat resembles the Pecterojous aiignstifro)is), 

 combined with the rufo-testaceous hue of its four anterior legs and 

 the base of its antennte (the former of which, however, have the 

 upper edge of their femora, and occasionally of the tibiae also, black), 

 will sufficiently distinguish it. Its prothorax has usually the sides 

 and base broadly testaceo-rufous ; but sometimes it is entirely dark, 

 except towards the hinder angles, whilst at others even the discal 

 patch is almost obsolete, when nearly the whole surface is pale. It 

 was taken from off flowers by Mr. Gray and myself on the hUls above 

 San Sebastian of Gomera, at the beginning of February 1858.
