species, in a small collection of insects made by Mr. Rogers. It is 

 of the most splendid brass-colour ; it was found near Rancho redondo, 

 on the Volcano of Irazu, by an Englishman who was in the company, 

 Mr. Rogers. 



This insect is now in the collection of Mr. Du Cane Godman. 



Plusiotis chrysargyrea. 



Pelidnota chrysargyrea, Salle, Aunales de la Soc. Ent. de France, 

 tome iv. p. 362. 



One specimen of this magnificent species, found in April in the 

 Candelaria Mountains, at the altitude of 5000 feet, in the oak-tree 

 region. 



It is quite perfect, and was taken alive on a roble tree (Tecoma 

 pentaphjlla, Jacq.). Being somewhat different from the types of the 

 species, I give a description of it : — 



Oblongo-ovata ; capite thoraceque aureo-pallidis, margine ruhro ; 

 elytris aureis, tenuiter punctatis, punctis in striis regulariter dis- 

 positis ; infra aurea, tibiis tarsisque cupreis, antennis fastis. 



Length 1 inch 1^ line. Mus. Boucard. 



Head, thorax, and elytra very slightly punctured, of a pale burnished 

 gold-colour with coppery-red reflections ; the anterior margin of the 

 head and the sides of the thorax of a coppery-red colour, which dis- 

 tinguishes this species from P. batesi ; tibiae and tarsi of the same 

 colour, with blue claws ; abdomen and pygidium of a brilliant golden 

 colour ; antennae rufous. 



Its place is near P. batesi, to which it is closely allied. 



Plusiotis l.ota, Sturm, Cat. 1843, p. 341. 



According to M. Auguste Salle, of Paris, who possesses the type of 

 P. Iceta, Sturm, this species must be abolished, as it was described 

 from a bad specimen of Plusiotis psittacina, which is from Mexico. 



This proves that I was right when I suggested in my former paper 

 that the locality of Valparaiso for this species was probably wrong ; 

 as up to this date no species of Plusiotis has been found south of 

 Columbia. 



Plusiotis badeni, n. so. (Plate XVI. fig. 2.) 



Oblongo-parallela, valde conve.va, supra viridi-argentea, capite 

 cnpreo-violaceo, medio viridi crebre punctulato ; thorace subtiliter 

 punctulato, margine cupreo-violaceo, scutello violaceo Itevi; elytris 

 tenuiter punctatis, punctis in striis profundis regulariter dispo- 

 sitis ; infra viridi-argentea, femoribus viridibus, tibiis cupreo- 

 violaceis, tarsis cupreo-aureis, antennis fuscis. 

 Length 7^ lines. 



Head of a coppery purple colour with the centre green, thorax 

 silvery green, with a broad margin of the same colour as the head, 

 both slightly punctured ; the scutellum is also of that same colour ; 

 elytra silvery green, slightly darker than the head and thorax, 

 strongly punctured, the punctuation disposed iu regular strise ; the
