Genus CALATHUS. 

 Bonelli, Observ. Ent. i. (1809). 



Calathus obliteratus, n. sp. 



C. ovatus, pone medium convexus, fusco-piceus, nitidus ; prothorace 

 conico, subdepresso, ad latera late subrecurvo; elytris basi de- 

 presso-desilientibus, in medio subinflato-convexis, linea basali in 

 utroque fere recta sed obsoleta obliterata, leviter striatis, interstitio 

 tertio punctis circa 6 notato ; antennis pedibusque rufo-testaceis, 

 tibiis tarsisque elongatis, gracilibus (horum art l mo praecipue 

 elongate). Long. corp. lin. 5|. 



Mas adhuc latet. 



Habitat Gomeram, in lauretis editioribus a DD. Crotch semel captus. 



06s. Species corpore ovato, pone medium subinflato-eonvexo, 

 prothorace valde conico, elytrorum linea basali obsoletii obliterata, 

 striis levibus sed haud tenuibus punctisque circa 6 ad striam ter- 

 tiam annexis, necnon tibiis (rectissimis) tarsisque elongatis gra- 

 cilibus inter cognatas subanomala distincta. 



In compiling the above diagnosis I have had but a single (female) 

 example, which was captured by the Messrs. Crotch in Gomera, to 

 judge from ; nevertheless it presents so many points of peculiarity 

 that there can, I think, be no question whatever as to its specific 

 claims. Its affinities, I imagine, are more with the C. abacoides and 

 coynatus than with any of the other species ; and therefore I have 

 little hesitation in placing it accordingly, even though I am unable 

 to pronounce for certain whether the posterior tibia? of its male sex 

 are simple or internally fringed. It may at once be known from the 

 allied forms by its ovate outline and posteriorly convex upper surface, 

 by its very conical prothorax, by its elytra having their basal line 

 obsolete (or obliterated), their striae shallow (though rather wide) 

 and with about six punctures adjoining the third one from the suture, 

 and by its tibia? and tarsi (the former of which are very straight, 

 whilst the latter have their basal joint longer than is usual) being 

 elongated and slender. 



Calathus fimbriatus. 



C. latiusculus, C. complanato plerumque paulo brevior, valde depres- 

 sus, piceus ; prothorace latiusculo ; antennis pedibusque fcrrugi- 

 neis. Long. corp. lin. 5-5^. 



Mas nitidus ; tibiis posterioribus intus (praesertim versus apicem) 

 pilis longis densissime fimbriatis. 



Fcem. opacus ; tibiis fere simplicibus. 



Calathus complanatus, var. y, Wull., Ins. Mad. 30 (1854).
