CALOSOMA AUROPUNCTATUM (Payk.). 



ORIGINAL DESCRIPTION. 



[Translation.] 



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

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



Description of male. 



Head entirely black; antennae 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. Tibiae curved. 



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

 not equal it in breadth. 



Female similar to male, but somewhat greenish above in color, coppery punctures 

 in triple row, abdomen scarcely broader, and anterior tibiae shorter. Habitat rare in 

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

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

 not at &\\ reticulated.

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

EARLY RECORDS OF THE SPECIES. 



This species was first described by Paykull in 1790 and its habitat 

 given as southern Switzerland. Dejean, in 1826, put it in the genus 

 Calosoma as it had previously been identified as Carabus. Gebier, in 

 1833, writes of the great similarity of this species to C. denticolle Gebl. 

 Houlbert and Monnot, in 1905, made a study of O. auropunctatum and 

 came to the conclusion that C. sericeum of Fabricius and O. indagator 

 of Gyllenhal were synonyms of it.
