OANAKTAN COLEOPTEEA. 479 



Habitat Canariam Grandcm, in arenosis subinaritimis jiixta Las 

 Palmas capta. 



The present species and the following one may at once be known 

 from the others here enumerated by the somewhat anomalous fact 

 (for the Pimeliadai) of their scutellum being so completely covered 

 by the pronotum as to be perfectly in\-isible from above, except 

 when the prothorax is unnaturally bent downwards so as to leave the 

 mesonotum exposed. It is consequently so extremely short that it 

 does not extend in the slightest degree beyond the basal line of the 

 elytra. I cannot, however, detect any other structural pecuKarities 

 to warrant their generic separation from the remainder. 



The P. (jranulkolUs is remarkable for its subopake surface, and 

 rather narrow, and densely and minutely granulated, prothorax. 

 Its elytra are roundish in oiitline (being a good deal subtruncated 

 posteriorly), closely and minutely, but lif/hth/, uneven (or malleated), 

 and have the lateral of theii' three costse pretty distinct, and made up 

 (particularly behind) of closely-set tubercles which form a serrated 

 line, whilst the two inner ones (though well defined) are but faintly 

 raised — the subsutural one being quite simple anteriorly, and the 

 discal one nearly so. As in the following species and the P. lutaria, 

 the upper, or concave, face of its tibiae is densely clothed with a 

 minute decumbent cinereous pubescence. It appears to be exceed- 

 ingly rare, the only specimens which I have seen (six in number) 

 having been captured by myself in Grand Canary — on the sand-hills 

 between Las Palmas and the Isleta — during March 1858. 



721. Pimelia auriculata. 



P. oblongior quam prrecedens, ac multo nitidior; prothorace paulo 

 latiore convexiore, basi sensim rectius truncate, esculpturato (tu- 

 berculis lateralibus exceptis) ; elytris minus ruguloso-ina3qTialibus, 

 sed juxta suturam grosse sod levissime transversim malleatis, gra- 

 nules perpaucis minutis (versus suturam minutissimis) parcissime 

 asperatis, singulis costa sublaterali tubercula majora ac multo 

 pauciora efflciente, discali vel indistincta (sensim serrata) vel obso- 

 leta, et subsuturali obsoleta ; spatio parvo ante oculos (mox intra 

 genas auriculatas) tibiisque in facie superiore breviter cinereo- 

 pubescentibus. — Long. corp. lin. 8-12. 



Pimelia bajula, Br. [nee Kltig, 1830], in Wehbet Berth. ( Col.) 57 (1838). 

 Habitat Canariam Grandem, hinc inde vulgaris. 

 That this is the Pimelia referred by M. Brulle to the Egyptian P. 

 bajula I can state for certain, having examined his specimens care- 

 fully, whilst in Paris. I have not been able to procure an example
