some new Species of Sagra, Sfc. 239 



Sagra P/eifferi, n. sp. 



Oblongo-ovata, crassa, viridi-senea, caeruleo micans, sub-nitida, 

 antennis extrorsum nigris ; thorace sub-quadrato, antice vix 

 producto, angulis anticis parum prominub's ; elytris ovatis, 

 basi truncatis, intra bumeros modice impressis, tenuiter reticu- 

 lato-strigosis, interstitiis ad apicem crenulatis ; gemellato- 

 punctato-striatis, striis fere deletis. 



Mas. — Femoribus posticis valde incrassatis, elytris fere dimidio 

 superantibus, subtus apice profunde sinuatis, sinu intus fulvo- 

 tomentoso, dentibus duobus validis armatis, horum secundo ad 

 angulum posticum emarginationis posito ; tibiis posticis apice 

 mucronatis, ante apicem bidentatis, dente externo valido ; ab- 

 dominis segmento basali vix deplanato, remote punctato, vage 

 flavo-tomentoso. 



Long. 10 lin. 



Robust, ovate, resembling S. quadraticollis in form, but rather 

 shorter and thicker than that insect, bright metallic green, with 

 metallic blue reflexions, sub-nitidous, outer half of antennae black, 

 opaque. Head finely punctured ; antennae robust, two-thirds the 

 length of the body, six basal joints shining metallic green. Thorax 

 sub-quadrate, almost transverse across the anterior angles, the 

 latter moderately prominent, anterior margin very slightly pro- 

 duced ; upper surface sub-opaque, impressed near the basal 

 margin with a shallow fovea ; sparingly covered near the base by 

 a few very minute punctures, only visible under a lens. Scutellum 

 semi-ovate, its base deeply excavated. Elytra shorter, ovate, 

 truncate at the base, their apex sub-acutely rounded ; above very 

 convex, moderately impressed within the shoulders, the latter 

 somewhat prominent, basilar space indistinctly elevated, bounded 

 beneath by a nearly obsolete transverse depression ; surface 

 covered with fine irregularly confluent grooved lines, more 

 crowded towards the apex, where their interstices are raised, 

 and form irregular crenulations ; on each elytron are six or seven 

 double rows of punctures, visible only here and there, principally 

 on the anterior half of the surface, being entirely obliterated for 

 the remainder of their course; on the outer disc, just before its 

 middle, is a small smooth spot, shining blue-green. 



Male. — Posterior thighs strongly incrassate, extending beyond 

 the elytra for nearly half their length, their outer surface very 

 convex, the thickest portion of the thigh being across its middle ; 

 lower edge deeply notched at the apex and armed with two stout 

 teeth, the anterior larger and situated immediately in front, the 

 other placed just at the posterior angle of the notch, the inner
