Cerylon humile. 
C. oblongum, rufo-ferrugineum, nitidum; prothorace transverso, fortiter 
punctato, lateribus subrotundatis; elytris subparallelis, seriatim punc- 
tatis. 
Hab, Ega? 
Much smaller than Cerylon angustatum, Er.; the prothorax transverse, 
with its sides slightly rounded, without any impressions at the base, 
and the elytra nearly parallel, and seriate-punctate rather than punc- 
tate-striate. Length 2 line. 
Of several species of Cerylon now before me, all very closely con- 
nected, this, I think, approaches most to the European Cerylon an- 
gustatum, Er., from which it differs principally in the characters of 
its prothorax and elytra as given above.

IX.—On the Canarian Longicorns. 
By T. Vernon Wottaston, M.A., F.LS. 
Or the sixteen Longicorns enumerated below, only nine, I imagine, 
can be regarded as certainly indigenous to the Canarian archipelago, 
—the remaining seven having, in all probability, either become na- 
turalized, or else accidentally introduced from other countries. How- 
ever, of the two Clyti and the Hesperophanes roridus, which I have 
included amongst the seven doubtful species (and which were re- 
corded originally from the scanty material amassed by MM. Webb 
and Berthelot), I am unable to speak with any precision, since they 
from the disk, and the humeral callosity not very apparent. It is also more opake, 
and covered with a sparse woolly pubescence. I add the diagnoses of this and 
the typical species, named but not described by Erichson. 
Discoloma vestita. Ovata, depressa, testaceo-brunnea, obscure griseo-pubescens ; 
elytris impunctatis, humero vix calloso. 
Hab. Mexico. 
Discoloma parmula (Er.). Ovata, depressa, flavo-brunnea, nitida ;*elytris sparse 
punctatis, limbo distincto, humero calloso. 
Hab. Cuba. 
Size and form of Discoloma paulla, but darker and nitid, with the elytra 
rather coarsely punctured.
