18/8.] MR. A. BOUCARD ON THE GENUS PLUSIOTIS. 295 



underside is of a paler green with silvery reflections ; tibiae coppery 

 purple, and tarsi coppery metallic ; antennae rufous. 



Hab. Mexico. 



The female of this species is of the same size, but a little wider ; 

 the tarsi are less coppery ; and the colour of the thorax, elytra, and 

 pygidinm is slightly paler. 



This species must be placed between P. gloriosa, and P. lacordairei. 



I have pleasure in naming this fine insect after my friend Doctor 

 Baden, to whom I am indebted for the specimen now in my collection. 



Types, museums Baden and Boucard.

Hab. Guatemala. 



I have only one specimen of this charming species, the only one 

 which was collected in the neighbourhood of Guatemala City by my 

 intimate friend Mr. Juan Rose Rodriguez, to whom I have the plea- 

 sure of dedicating this fine insect. It was found by him in the forests 

 of oak trees near the capital. Its place is between P. costata and 

 P. sallei, Bouc.
