Like the last species, the C. barbatus would appear to be pe- 
culiar to Grand Canary,—descending, however, into sub-sylvan 
spots of a rather lower elevation than those tenanted by that 
insect. It may be known from it by its very much smaller size 
and by its sexes being almost equally shining, its prothorax 
being in them both (as is the case with all the Canarian Calath 
except the appendiculatus) equally polished. In minor charac- 
ters, its elytra are a trifle more convex than those of the appendt- 
culatus, and have their basal line rather more curved; and the 
four hinder tibiz of its males are fimbriated along a rather shorter 
portion of their inner edge. I took it, not uncommonly, in the 
region of El Monte, as also on the mountains of Tarajana, 
during the spring of 1858. 
16. Calathus spretus, n. sp. | 
C. fusco-piceus, subconvexus ; capite prothoraceque nitidis, hoe sub- 
quadrato, postice vix latiore, ad latera paulo pallidiore et leviter 
recurvo; elytris subconvexis, ovatis, paulo (preesertim in sexu 
foemineo) obscurioribus, linea basali in utroque recta, leviter striatis, 
interstitiis (in utroque sexu) subdepressis, tertio punctis 3-4 di- 
stinctis notato; antennis pedibusque rufo-testaceis. 
Mas tibiis posterioribus (sed preesertim intermediis) intus versus 
apicem paulo densius ciliatis. 
Fem. tibiis simplicibus, 
Long. corp. lin. 4-43. 
Habitat in ins. Hierro, mense Februario a. p. 1858 deprehensus, — 
In general aspect the present Calathus comes so near to the 
C. barbatus, that, were it not for the essential differences displayed 
by the tibie of the males of the two species, I should not have he- 
sitated to consider them as identical ; but since the former has the 
four hinder tibiz of its malesa/most simple internally, andthe poste- 
rior pair straight, whilst the latter has them powerfully fimbriated, 
with the posterior ones slightly curved, I cannot but regard 
them as dissimilar, and so lay greater stress on the other minute 
differences which they display inter se than I should ordinarily
