nevertheless the latter are, I think, quite sufficiently so to warrant 
its admission into my second section. Although M. Brullé’s very 
brief and meagre description applies almost equally to about 
two-thirds of the Canarian Calathi, yet, with the assistance of 
his figure and of the size there given of it (though, as already 
mentioned, that length does not tally with what he states), I 
believe that this is the insect to which he intended to apply the 
name of C. depressus, and I have consequently quoted it as 
such. 
It is universal within the sylvan districts of Teneriffe, and is 
perhaps the most common of the Canarian Calathi; neverthe- 
less, although widely distributed over the island, I have never 
met with it in actual profusion anywhere. I have taken it at 
and above Ycod el Alto, at the Agua Mansa, and at the Agua 
Garcia, as also at Las Mercedes and in the woods towards Ta- 
Sey, and Point Anaga. I have likewise received it from the 
arao do Castello de Paiva, and from Professor Heer of Zurich, 
who obtained it from M. Hartung. 
14. Calathus appendiculatus, un. sp. 
C. fusco-piceus, depressus ; capite nitido; prothorace subequali, 
subquadrato, postice latiore, ad latera paulo pallidiore anguste et 
leviter recuryo, ad basin ipsissimam fere immarginato; elytris 
linea basali in utroque recta, striatis, interstitio tertio punctis circa 
3-5 sat distinctis notato ; antevnis pedibusque testaceis. 
Mas omnino nitidus, interstitiis subconvexis; tibiis posterioribus 
intus densissime fimbriatis. 
Fem. prothorace elytrisque opacis, interstitiis valde depressis ; tibiis 
simplicibus. 
Long. corp. lin. 53. 
Habitat Canariam Grandem: in montibus sylvaticis inter oppida

Apart from all other characters, the peculiar sexual differences 
of this fine Calathus (the males of which are entirely bright, 
whilst the females have their prothorax and elytra opake) will at 
once separate it from all the others as yet detected at the Cana- 
ries. In their elytral impressions, the present insect and the 
two following ones are on the ordinary type, the number being 
reduced to three or four on the third interstice, from which it 
would appear that those species which have them more or less 
increased are, according to the data hitherto accumulated, con- 
fined to Teneriffe. The C. appendicu/atus seems to be peculiar 
to the sylvan regions of Grand Canary, where, on the 21st of 
April, 1858, I captured several specimens of it, beneath moist 
rotting bark, in the remains of the ancient forest of E] Dorames, 
on the mountain road between Galdar and Teror.
