Genera of the Cossonidcc. 531 



divaricate), the two together thus constituting a single 

 joint, bifurcated at its tip. And from the analogy of the 

 similar (though more enlarged) lobes at the angles of the 

 joints which precede it, I conclude that these two terminal 

 diverging processes do not represent the claws (which seem 

 to be altogether absent), but rather the prolongations of 

 the anterior angles of the ultimate joint. 



In its habits Onyclwlips appears to be much the same 

 as Pentatemnus and Lipommata, though more decidedly 

 fbssorial, its spinulose posterior tibia3 being eminently on 

 a burrowing pattern ; and it is still more conspicuously 

 beset (like so many sand-infesting insects), with remote, 

 elongated hairs. Indeed, these latter are not confined to 

 the body alone, both the scape and club of the antenna 

 being singularly pilose. I have captured it in the three 

 eastern islands (Lanzarote, Fuerteventura, and Grand 

 Canary) of the Canarian archipelago, where it resides 

 on, and beneath, the surface of the sandy hillocks, in the 

 vicinity of the coast, which have accumulated gradually 

 around the roots of the few shrubby plants which stud 

 those arid spots. 



33. RAYMONDIONYMUS (== RAYMONDIA, pars, Aube, 

 Ann. de la Soc. Ent. de France, 195. 1861). The 

 blind and anomalous genus Raymond! onymus (or Ray- 

 ?nondia*), which appears to occur in Mediterranean lati- 

 tudes, has somewhat the fusiform outline, rather elongated 

 rostrum, and rufo-piceous hue of Amaurorrhinus ; but its 

 funiculus is composed of six articulations (instead of only 

 five), its metasternum is shorter still, its tibia3 (which have 

 no terminal hook) are compressed and triangularly dilated, 

 and its feet are short, broad, and thick, furnished with long 



* I regret that it should be absolutely necessary to change the name of 

 this gcnns,"liaymondia" having been preoccupied by M. Frauenfeld, for 

 a group of the Diptera (vide Sitzungsb. d. Wien. Acad. xviii. 320), six years 

 before it was employed by Aube. In real fact, however, this is perhaps 

 the less to be deplored, since I strongly suspect (judging from the diagnosis 

 and figure) that Aube's R.fossor is not actually congeneric with the larger 

 species which have subsequently been associated with it, but more properly 

 with Alaocyba, as recently enunciated by Ferris ; and if this should be the 

 case, it follows that the larger species, of which I would regard the R. Mar- 

 quetl as the type, have not yet been separated generically from the smaller 

 ones. Be this however as it may, the title " Ilayniondia" must of neces- 

 sity be altered ; and therefore, being unwilling to disconnect the group 

 with the name of the eminent Coleopterist to whom it was originallv dedi- 

 cated, I have (rather than take the opposite alternative) proposed for it, 

 instead, the perhaps not altogether euphonious one of Baymondionymiis.
