11. Calathus auctus, un. sp. 
C. fusco-piceus, angustulus, depressus ; capite prothoraceque sub- 
nitidis, hoc ineequali, angustulo, subconico, ad latera paulo palli- 
diore late et valde recurvo; elytris subellipticis, linea basali in 
utroque profunde arcuata (ergo ad humeros valde acutis porrectis), 
striatis, interstitiis (in utroque sexu) depressis, tertio punctis circa 
10-14 et quinto circa 6—9 valde distinctis notatis; antennis pedi- 
busque elongatis, rufo-testaceis. 
Mas elytris opacis ; tibiis posterioribus intus versus apicem densis- 
sime fimbriatis. 
Fem. elytris valde opacis ; tibiis simplicibus. 
Long. corp. lin. 6-7. 
Habitat Teneriffam humidam excelsam, in iisdem locis ac preecedens. 
As already implied, the rather smaller size and less widened 
outline of the present Calathus (the prothorax of which is espe- 
cially narrower and more conical), in conjunction with its more 
elliptic elytra (which have their basal line more curved, and their 
shoulders consequently acuter or more porrect) and its more 
numerous discal punctures, will at once separate it from the last 
species. It differs also in its males having the elytra somewhat 
more opake (with the interstices flatter), and the four hinder 
tibie fimbriated along a rather shorter portion of their inner 
edge. At the same time, I should add that I am by no means 
perfectly satisfied that it may not be an extreme state of that 
imsect. The C. auctus is found in precisely the same spots as 
the ciliatus, occurring in damp localities at a high elevation on 
the mountains of Teneriffe. I took it, in company with that 
species, during May of 1859; and it has been communicated by 
Professor Heer of Zurich (captured by M. Hartung), as also by 
the Bardo do Castello de Paiva. 
12. Calathus angustulus, n. sp. 
C. pallide fusco-piceus, angustus, subdepressus ; capite prothoraceque 
nitidis, hoc angustulo, subquadrato, postice vix angustiore, ad latera 
paulo pallidiore anguste recurvo ; elytris ellipticis (antice et postice 
subzequaliter rotundatis), opacis, linea basali in utroque profunde 
arcuata, striatis, interstitio primo (ad basin) punctis 1-3, tertio 
circa 12-16, quinto circa 8-12 et septimo circa 8-14 valde di- 
stinctis notatis; antennis pedibusque rufo-testaceis. 
Mas interstitiis subconvexis ; tibiis posterioribus intus dense sed 
breviter fimbriatis. 
Feem. interstitiis depressis ; tibiis simplicibus. 
Long. corp. lin. 43-5. 
Habitat Teneriffam excelsam humidam, sub lapidibus corticeque 
arborum laxo putrido, rarior.
