1875. ] MR. A. BOUCARD ON THE GENUS PLUSIOTIS. 121 
argenteo-viridis, elytris levibus margine lato argenteo-splen- 
dido, tibiis et tarsis aureis, antennis piceis. Length 11 lines. 
Hab. Chiriqui (Veragua). 
This species has been well described by Mr. Charles Waterhouse 
in the ‘ Entomologists’ Monthly Magazine’ for June 1871. The type 
is in the collection of the British Museum. Besides, another speci- 
men of this charming species is in the collection of Mr. H. W. Bates. 
My description was taken from this specimen. 
It is one of my desiderata.

Plusiotis ornatissima, Sturm, Cat. 1843, p. 341, t. 3. f. 7. 
P. adelaida: oblongo-ovata, capite thoraceque viridibus, margine 
aurato ; elytris viridibus, lineis argentatis ; infra viridi-enea, 
tibiis cupreis, tarsis cupreo-metallicis, antennis rufis. Length 
1 inch 2 lines to 1 inch 4 lines. 
There is a fine variety of this species, with the head and the 
thorax green, with rufous lines, the elytra rufous with silvery lines 
and gold margin. This variety has been described by Sturm as 
ornatissima. 
I met with this fine insect at La Parada, near Oaxaca (Mexico), 
during the year 1858. It used to fly about at sunset ; and I was able 
to catch several specimens by running after them with a butterfly-net. 
May and June are the months when there is some chance of meeting 
with this insect. 
As La Parada is a very mountainous country, covered with pines 
and oaks, it is very probable that it feeds on the leaves of these trees. 
My colleague (of the Commission Scientifique du Mexique), M. 
Bocourt, has found a certain number of this species in Guatemala. 
It is in the collections of the Jardin des Plantes of Paris, of the 
British Museum, MM. Mrizech, Sallé, Bates, &c.

P. leta: viridi-prasina, pedibus subauratis, tarsis eneis nitidiori- 
bus ; elytris costatis, interstitiis latioribus, punctatis. Length 
1 inch. 
This species is very closely allied to P. adelaida, from which 
(according to the description of Sturm) the only difference to be 
observed is in the colour of the tarsi, which are of a shining brassy 
green instead of metallic coppery. It is said to be from Valparaiso ; 
but I believe this to be very doubtful, and, unhappily, I have not 
been able to see the species.
