CALOSOMA AUROPUNCTATUM (Payk.). 



ORIGINAL DESCRIPTION. 



[Translation.] 



Black, smooth, Trith thorax emarginate posteriorly, elytra finely punctate-striate, 

 and punctures of uneven depth a little larger in triple row. 



Description of male. 



Head entirely black'; antenna becoming brown at the apex. 



Thorax black, smooth, marginate, obovate, almost twice broader than long, sides 

 rounded; truncate anteriorly, somewhat emarginate posteriorly. 



Elytra black, scarcely broader than the thorax, very finely punctate-striate: 

 punctures a little larger depressed in triple row. 



Sternum black. 



Abdomen black. 



Feet black. Tibite curved. 



In size and length it almost exceeds the preceding, (Carabus reiiculatus) but it does 

 not equal it in breadth. 



Female similar to male, but somewhat greenish aboA'e in color, coppery punctures 

 in triple row, abdomen scarcel}^ broader, and anterior tibiae shorter. Habitat rare in 

 Sfmthern Switzerland. It differs from Carabus inquisitor in color, in emarginate thorax 

 and smootlier elytra, from Car. reticulatus in color, body more elongated and elytra 

 not at all reticulated.

 gator? is related to this, but this one is wingless as only a hasty description was seen 

 by the author. 



EARLY RECORDS OF THE SPECIES. 



This species was first doscril)ed by Paykull in 1790 and its habitat 

 given as southern Swilzei-lund. i)('j<-aii, in 182(5, put it in the genus 

 Calosoma as i1 had pnn^iously been i(hMiLified as Carabus. Gebler, in 

 \KV.i, writes of the great similarity of this specic^s to O. denticolle Gebl. 

 Houlbert and Monnot, in 1905, mack; a study of C. auroj)unctatum and 

 came to the conclusion that (J. sericeum of Fabricius and (J. indagator 

 of Gyllenhal w<!j'(; syiionyms of it.
