following one ; tliorax transversely suboval ; abdomen subquad- 

 rate. 



1. C. sCRrTATOR. — Violaceous; thorax with a golden margin ; 

 elytra green margined with reddish-cupreous. 



Length from twenty-three-twentieths to fiye-fourths of an 

 inch. ■ [74] 



Carabus scrutator Oliv. Ent. No. 35, pi. 3, 32, a. b.

Body beneath green yaried with golden cupreous ; head im- 

 punctured, black, with violaceous reflections, orbits above golden; 

 antennae with ferruginous hair towards the tip ; beneath green ; 

 tooth of the labium very short, hardly prominent ; thorax im- 

 punctured, blackish-violaceous, with an uninterrupted golden 

 margin, dorsal line abbreviated, obsolete, basal lines none, basal 

 edge subrectilinear, the lateral angles not extending backwards ; 

 elytra bright green with a very slight cupreous reflection ; striae 

 reticulated by much smaller transverse lines which are more 

 deeply impressed in the striae so as to resembles transverse punc- 

 tures, stritK fifteen, transverse lines very numerous, fourth, eighth, 

 and twelfth interstitial lines each with several distant impressed 

 punctures, exterior margin reddish-cupreous; feet violaceous: 

 venter green, incisures each with a golden cupreous base and 

 lateral spot. 



Var. a. Head distinctly punctured, disk of the thorax green 

 with a very slight violaceous tint ; length nine-tenths of an inch. 



This species makes a very near approach to the sycophanta of 

 Europe ; but, as Dr. Leach observes, it difiers from that insect in 

 color, in being less convex, and in having a shorter thorax. 



2. C. CALIDUM.— Black ; elytral striae reticulated, equal, with 

 a triple row of indented gold dots. 



Length from nine-tenths to nine-eighths of an inch.

Carabits calidus Melsh. Catal. 



Head black, wi^h crowded minute confluent punctures ; an- 

 tenna brown towards the tip ; [75] thorax black, with crowded, 

 minute, confluent punctures, posterior lateral margin reflected, 

 posterior angles rounded and extending backwards beyond the
