450 INSECTA MADERENSIA. 



busque (apice femorum posticorum picescente excepto) testaceis, prothorace parvo antice angus- 

 tato, elytris saturate testacescentibua leviter punctato-striatis. 

 Long. Corp. lin. 1|. 



Habitat super plantas cruciferas in vinetis hortisque culinaribus Maderse et Portus Sancti, aestate 

 rarior. 



P. subelliptical and rather slender, more depressed than any of the other species, shining, and 

 greenish- (or dark) seneous. Antenna at base, and ler/s (except the picescent apex of the two 

 hinder femora), testaceous. Prothorax more coarsely punctulated than that of the P. chrijso- 

 cephala ; very small, and narrowed in front. Ehjtra less acuminated behind than in the last or 

 following species ; of a diluted brassy-testaceous hue ; faintly punctate-striated ; and with the 

 interstices distinctly punctulated. Antenna at apex dark fuscous. 



Likemse, in all probability, an introduced insect into the Madeira Islands, — 

 occurring only, I believe, in vineyards and cultivated spots in and about the towns 

 (especially on plants allied to Sinapis, and other Cniciferce) ; nevertheless, not 

 ha\dng been able to identify it with any recorded species, I have been compeUed to 

 describe it as new. It may be known by its more depressed, less apically-aciuni- 

 nated form, by its small and rather coarsely punctured prothorax, and by the 

 brassy-testaceous hue of its {lightly punctate-striated) elytra. It is apparently the 

 only Madeu-an PsylUodes in which the wings are fully developed. I have taken 

 it, sparingly, in gardens near Funchal ; as also in Porto Santo, in the immediate 

 vicinity of the Cidtide.

P. obovato-elliptica convexa nitida aenescenti- (vel cyanescenti-) vii-idis, antennarum basi pedibusque 

 (apice femorum posticorum picescente excepto) testaceis, prothorace parvo antice angustato. 

 elytris punctato-striatis. 



Long. corp. lin. 1|. 



Habitat in gi-aminosis humidiusculis Maderre, inter 2000' et SOOC s. m., sestate rarissima, locis snni- 

 libus ac Longitarsus nubigena occurrens. 



P. somewhat short and thick, obovate-elliptical, convex, exceedingly shinhig, and of either a brassy- 

 or bluish-green. Antenna at base, and legs (except the picescent apical portion of the two hinder 

 femora), testaceous. Prothorax neither quite so small, nor so coarsely punctulated as m the 

 P. hospes ; narrowed in front. Elytra acuminated behind ; rather deeply punctate-striated, and 

 with the interstices very distinctly punctulated. Antenna at apex fuscous. 



Distinguished by its somewhat thickened and exceedingly convex body, and by 

 its very shining, brassy-green hue. It is in all prol)ability a truly indigenous 

 insect to Madeira, occurring in remote spots of a lofty elevation, where it is 

 scarcely likely to have become natm-alized. It is apparently very rare, the few 

 examples which have come under my observation having been captured by myself
