stones in grassy spots, and in Madeira are most abundant at intermediate and 

 lofty altitudes. 



20. Calathus vividus. 



C. apterus fusco-piceus, prothorace augusto elongato-quadi'ato lateribus valde reflexis ferrugiiieis, 



elytris ovatis profunde striatis, siugulo punctis tribus vel quatuor impresso, antennis pedibusque 



longissimis testaceis. 

 Long. corp. lin. 6-7. 



Carahus vividus, Fab. (testibus D.D. Scliaum, AVestermann et Scbiodte) Syst. Eleu. i. 194 (1801). 

 Sclion. Syn. Ins. i. 199 (1806). 



Habitat sub lapidibus truncisque arborum prolapsis in montibus JMaderse, sat frequens. 



C. apterous, light brownish-piceous, rarely dark ; the males slightly shining, the females opake. 

 Head and pruthurax elongated ; the latter narrow and nearly parallel, mth the sides usually much 

 reflexed and ferruginous ; longitudinally channelled in the centre, and with a large impunctate 

 fovea on either side at the base. Elytra ovate, broadest about the middle, deeply striated, and 

 each with three or four usually distinct impressions down its disk near the third stria from the 

 suture. Legs and antenna exceedingly long, and, with the palpi, usually pale ferruginous, or 

 testaceous. 



The present species may be cUstinguished from every variety of the C. con/p/a- 

 natiis by its larger size, by the greater length of its legs and antennse, and by its 

 narrow, elongated, parallel prothorax, which has the lateral margins usually much 

 recurved. The colour also is generally somewhat paler than in that insect, and its 

 legs and antennse are more testaceous. It is decidedly rarer than either of the 

 other Madeiran Calathi, nevertheless it is sufficiently abundant in certain districts 

 of a lofty elevation. I have taken it near the summit of the Pico Ruivo, at al)out 

 6000 feet above the sea ; and it was captured by Professor Heer on the Pico dos 

 Bodes and at the Jardina de Serra, ia 1851. That the insect is correctly identified 

 I am enabled to state on the authority of my fi'iend Dr. H. Schaimi of Berlin, wlio 

 examined the original type in the Royal Museum of Copenhagen in the year 1815. 

 This conclusion has been recently corroborated by a communication from M. Dohrn 

 of Stettin, who forwarded my own specimens for comparison to Copenhagen, where 

 they were pronounced, by both "VYestermann and Schiodte, to be imquestionably 

 the true Carohus vividus of Fabricius. It is -wi'ongly stated in the Systemu Eleu- 

 tliemtorum to be winged, since, like the rest of the Madeiran Calathi, it is invari- 

 ably apterous : and had not the original tyjies been stUl in existence, it would ha-\e 

 been impossible to have recognised oiu^ present insect in the miserably poor 

 diagnosis there given of it, which would seem indeed, — if it conveys the slightest 

 idea of anything at all, being equally applicable to about two-thirds of the entire 

 CaraUdce, — to be better adapted perhaps to the Sarpalus which Dejean erro- 

 neously, though not unnaturally, afterwards referred to it, than to the Calathvs 

 now under consideration.
