3. Pecteropus angustifrons, n. sj). (PI. XX. fig. 1.) 



P. cyaneo-niger prothorace laete rufo, pubescens ; capite angusto, ovali, 

 opaco, densissime et minute subgranulato-rugoso, fronte excavato- 

 depressa, oculis minus prominentibus, clypeo pallido ; prothorace in 

 disco nitido et ibidem distincte punctulato; elytris nitidis, dense 

 ruguloso-punctulatis ; antennis ad basin pedibusque anterioribus rufo- 

 testaceis, tibiis anterioribus in toto femorib usque ad apicem ipsum plus 

 minus infuscatis ; pedibus posticis nigris, femoribus ad basin rufo- 

 testaceis. 



Mas antennis vix longioribus, tibiis anticis subcurvatis, tarsorum anti- 

 corum articulo secundo in lobum brevissimum pectinato-spinosum aegre 

 observandum supra producto. 



Variat prothorace in disco antico interdum nigro-nebidoso.

Apart from its structural characters (of narrower and more rostrate 

 head, &c.) which have already been pointed out, the present insect 

 is prima facie remarkable amongst the Attali, to which it necessarily 

 bears a general resemblance, by its brightly rufous prothorax and 

 dark-cyaneous elytra and head, the latter of which is subopake, and 

 most densely and minutely roughened. Its four anterior legs also 

 are more or less rufo-testaceous, whilst the two hinder ones are 

 nearly black. The second joint of the front feet of its males is so 

 very slightly produced into a hood-like lobe on the upper side that 

 the latter is scarcely perceptible, except beneath the microscope ; 

 but when thus viewed it will be seen, nevertheless, to be more 

 strongly pectinated, or spinose, than is usually the case in the true 

 Attali. Hitherto it has been observed only in Gomera, where, 

 during February 1858, it was taken sparingly by Mr. Gray and 

 myself from off flowers on the ridge immediately to the north of San 

 Sebastian. 



Genus Attalus.

In describing the following Attali I do not think it necessaiy to 

 indicate their sexual distinctions, which are almost exactly the same 

 in the whole of them. It will be sufficient to state here that the 

 males have their antennas usually just perceptibly longer, their eyes 

 a trifle more prominent, their elytra for the most part somewhat less 

 ovate (or more parallel at the sides), and the second joint of their 

 fore tarsi produced externally into a more or less elongated, concave
