PLUSIOTIS. 277 



teristic of the Central- American region, including the southern borderlands of the 

 United States. I have seen two species only (one of which belongs to the burnished- 

 metallic group of the genus*) from South America. P. lazta, Sturm (=P. psittacina), 

 the type specimen of which is in the Salle collection, is a Mexican species recorded 

 erroneously from Chili. 



1. Plusiotis victorina, (Tab. XVI. fig. 13, s .) 



Pelidnota victorina, Hope, Proc. Ent. Soc. Lond. 3 Aug. 1840 (vol. iv. Proc. p. 8) \ 

 Plusiotis victorina, Burm. Handb. der Ent. iv. 1, p. 418 2 . 



Hab. Mexico \ Tepansacualco (Salle), Oaxaca {Edge ; Fenochio, in coll. Bates), 

 Villa Alta in Oaxaca 2 . 



Burmeister places this remarkable species at the head of the genus. 

 An example from Tepansacualco is shown on our Plate. 



2. Plusiotis boucardi. 



Plusiotis Boucardi, Salle, Ann. Soc. Ent. Fr. 1878, Bull. p. xvii * ; Boucard, Proc. Zool. Soc. 1878, 

 p. 296, t. 16. fig. 3. 

 Hab. Costa Rica (Van Patten), mountains of Candelaria 5000 feet (Boucard, 1 ). 



Most examples are smaller than P. victorina (27-32 millim.), to which it approaches 

 in the dark brick-red colour with coppery tinge of the underside, and in the sculpture 

 of the elytra. The whole upper surface is apple-green, with yellowish reflections. 

 The pygidium in the male is strongly convex near the apex, in the female convex in 

 the middle with retuse compression on the sides. The mesosternal process is subelon- 

 gate and acutely conical as in P. victorina. 



3. Plusiotis aurora, 



Plusiotis aurora, Boucard, Proc. Zool. Soc. 1875, p. 119, t. 23. fig. 7\ 

 Hab. Panama, Veragua 1 . 



I know this species only from the description and figure given by Boucard ; the 

 following is a variety, or possibly the typical form of it : — 



Var. Plusiotis chrysopedila. (Tab. XVI. fig. 12.) Elongato-oblonga, pomaceo-viridis rufescenti-relucens, 



* Plusiotis argenteola. 



P. resrplendenti affinis, splendidissime argentea subaurata, sed quoad formam valde differt, magis elongata 

 elytrisque ad trientem apicalem latioribus. Clypeus (cT?) antice sinuato-angustatus, margine apicali 

 reflexo et sinuato ; capite et thorace distincte disperse punctulatis et crebre subtilissime vix impresse 

 punctulatis; elytris striato-punctulatis, interstitiis subtilius punctulatis, margine laterali tenui usque 

 prope apicem coutinuato, versus basin verticaliter dilatato, intus stria punctata delimitate); subtus 

 splendide aurata, tibiis rosaceis, tarsis nigris. Mesosterni processus acute conicus, validus. Pygidium 

 versus apicem valde convexum, punctulatum, glabrum. 



Long. 32 millim. c? • 



Hab. Colombia, inter Pasto et maris Pacifici littora.
