350 Mr. T. V. Wollaston on the Calathi 
prothorax (which is a trifle narrower behind than before) and 
the exceedingly numerous punctures on the alternate interstices 
of its elliptic elytra, will at once characterize it. It is the only 
Canarian species on which I have observed punctures on the 
fist elytral interval, there being usually two or three at the ex- 
treme base. Its smaller size and less-margined, differently 
shaped prothorax, added to its more-rounded, less-flattened ely- 
tra and more numerous impressions, will, apart from other dif- 
ferences, readily separate it from the last species. Indeed, in 
general contour it has perhaps more in common with the C. ca- 
rinatus than with any other member of the genus here described; 
but its paler colour, narrower and somewhat less depressed elytra 
(with their more numerous punctures and less arcuated basal 
line), in combination with its posteriorly narrower prothorax 
and the fimbriated hinder tibiz of its male sex, will immediately 
distinguish it from that insect. The C. angustulus occurs 
sparingly throughout the sylvan regions of Teneriffe, especially 
towards their upper limits, where it may be found under damp 
stones and beneath the loose rotting bark of trees. In such 
positions I have taken it on the ascent from Ycod el Alto to the 
Cumbre, at the Agua Mansa, and in the laurel-woods above 
Point Anaga and Taganana. It has also been communicated by 
the Bardo do Castello de Paiva. 
13. Calathus depressus. 
C. nigro-piceus, latus, subdepressus ; capite prothoraceque nitidis, 
hoe subquadrato, postice lato, ad latera vix pailidiore et paulo re- 
curvo ; elytris basi latiusculis, linea basali in utroque leviter ar- 
cuata, sat profunde striatis, interstitiis (in utroque sexu) sub- 
depressis, tertio punctis circa 6-10, quinto circa 5-7 et septimo 
circa 1—3 distinctis notatis ; antennis pedibusque piceo-testaceis. 
Mas tibiis intermediis versus apicem vix fimbriatis (posticis fere, 
forsan omnino simplicibus). 
Fem. tibiis simplicibus. 
Long. corp. lin. 4-5. 
Calathus depressus?, Brullé, in Webb et Berth. (Col.) 55, pl. 2. f. 1 (1838). 
Habitat in sylvaticis Teneriffee, sub lapidibus sat vulgaris. 
The dark hue and broad outline of this Calathus (the pro- 
thorax of which is considerably wider behind than in front, and 
is but slightly recurved at the edges), added to its rather deeply 
striated elytra (which are subopake in both sexes, and have their 
discal punctures of the number indicated above), will sufficiently 
characterize it. The hinder tibie of the male are almost (if not 
indeed entirely) simple; and even the intermediate ones are but 
very shortly and obscurely fimbriated towards their mner apex:
