1875. ] MR. A, BOUCARD ON THE GENUS PLUSIOTIS: 123 
I have two specimens of this very rare species, one of which is the 
original type from which Mr. Gray took his short description. 
PuusroTis psitracina, Sturm, Cat. 1843, p. 340, t. 3. f. 6. 
P. psittacina : odlongo-ovata, supra viridi-prasina, fortiter punctu- 
lata; tibiis rufis violaceo-micantibus, tarsis aureis. Length 1 
inch 4 lines. 
This species has been considered by MM. Gemminger and Harold 
to be identical with P. auripes; but, having the typical specimen 
of the latter in my possession, and having examined attentively along 
with Mr. Charles Waterhouse the specimen in the collection of the 
British Museum under the name of psittacina, Sturm, which speci- 
men has still the label of Mr. Sturm’s own handwriting, we have come 
to the conclusion that it is altogether a good species, different from 
P.auripes,Gray. The elytra are much more punctuated, the colour 
is apple-green all over instead of a dark green,’and the tibiz are 
rufous, with purple reflections; it is also much longer, being 1 inch 
4 lines in length. 
Puusiotis costata, Blanch. Cat. Coll. Ent. 1850, p. 210. 
P. costata : oblonga, convexa, supra viridis, capite fortiter punctu- 
lato; thorace subtiliter punctulato, margine aureo-micanti ; 
elytris punctatis, punctis in striis regulariter dispositis, tibtis 
tarsisque aureo-viridibus, antennis rufis. Length 1 inch 2 lines 
to | inch 5 lines. 
Hab. Mexico. 
This handsome species-was described by Professor Blanchard on a 
red specimen which must be considered really only a variety of the 
species. His description is nearly the same as the above ; but, instead 
of being green, the head, thorax, elytra, tibice, and tarsi are described 
as of a brilliant red coppery colour. There is also a variety of the 
same red coppery colour, but darker, with purple reflections. 
I have a very fine series of this species with its varieties. Spe- 
cimens are also in the collections of the British Museum, Jardin 
des Plantes, Mnizech, and Sallé. 
PLusioTIs SALLI, sp.n. (Plate XXIII. fig. 3.) 
P. salleei: ovata, convexa, supra viridis ; capite crebre punctulato; 
thorace subtiliter punctulato, margine cupreo-pallido, scutello 
levi; elytris punctatis, punctis in stris regulariter dispositis ; 
infra viridis, femoribus viridibus, tibiis, tarsis, antennisque rufis 
violaceo tinctis. Length 1 inch 1 line. 
Head green, strongly punctured ; thorax green, slightly punctured, 
with a broad pale coppery margin on each side, which distinguishes 
at once this species from P. auripes and P. costata. Elytra 
punctured, the punctures disposed in regular strize ; tibize, tarsi, and 
antennez rufous, with a purplish reflection. 
Hab. Mexico. 
I have only one specimen of this rare species, which was taken in 
the neighbourhood of Orizaba.
