3. C. VIRIDIPENNIS. — Elytra green, polished, margined with 

 cupreous. 



Carabus prasinus Melsh. Catalogue. 



Inhabits Pennsylvania; rare. 



Body destitute of hairs ; head purple-black ; vertex gla- 

 brous ; front impressed each side near the antennae ; antennse 

 testaceous, rather darker towards the tip j thorax green, 

 tinged with purple ; a longitudinally impressed line, and trans- 

 verse, minute, parallel ruga3; posterior angles angulated ; be- 

 neath purple-black, green each side ; feet purple-black, paler to- 

 wards the tips; penultimate tarsal joint bilobate; scutel testa- 

 ceous ; elytra striate, green, polished, reflecting in some lights a 

 slight purpuresceut tinge ; outer margin cupreous ; striae distinct, 

 acute, distant, the marginal one with distant punctures from the 

 humerus to the apex ; venter blackish. 



Length half an inch. 



This was sent to me by Dr. J. F. Melsheimer ; I have not found 

 a specimen, and therefore have considered it as a rare [10] spe- 

 cies. The name prasinus having been already applied to a dif- 

 ferent species has rendered it necessary to change it. 



[Belongs to Calleida, and described by Dejean as C. margi- 

 nata. — Leg.] 



4. C. PURPUREUS. — Purple or violaceous; antennae, mouth 

 and tibiae black. 



Length seven-twentieths of an inch. 



Head obsoletely punctured, deep violaceous ; antennae fuscous, 

 three basal joints rufous, obscure ; trunk deep violaceous ; a lon- 

 gitudinal impressed line, and transverse obsolete rugae ; elytra 

 deep violaceous, obsoletely punctured, and with minutely punc- 

 tured, acute, distant striae; a line of marginal punctures ; tibiae 

 and tarsi black-brown ; penultimate tarsal joint bilobate ; venter 

 violaceous ; tail black. 



In form and magnitude resembles C. viridipennis, but is more 

 depressed and wider. Brought by Mr, Nuttall from the Mis- 

 souri. 



[I have referred this species to Gl^cia Chaud., but have 

 since failed to find sufficiently distinct characters for that genus 

 to enable me to confirm this reference. The present species be- 

 1823.]
