This was sent to me by Dr. J. F. 3Ii'lsheimer ; I have not found 

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

 cies. The name prasiiius 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 ; antennx, mouth 

 and tibiae black. 



Length seven-twentieths of an inch. 



Head obsoletely punctured, deep violaceous ; antennae fuscoue, 

 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. viridipennt's, but is more 

 depressed and wider. Brought by Mr. Nuttall from the 31i8- 

 souri. 



[I have referred this species to Gli/cia Chaud., but have 

 since failed to find sufliciently distinct characters for. that genus< 

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

 1823.]
