ANALYSIS OF THE GKNERA. 



Marginal vein very sliort or wautiDg. 



Mesoscutum with a sculpture very similar to that of head. 



Mesoscutura very short, only half as long as scutellum; autennal club as 

 lung as all funicle joints together; postmargiual vein as long as stig- 



mal Chalcaspis. 



Mesoscutum at least as long as scutellum ; autennal club shorter than funi- 

 cle; postmargiual vein much shorter than stigmal Bothhiothorax. 



Mesoscutum with punctures less dense than those of head, and with a plain 

 shagreeniug of the surface; autennal club shorter than funicle; postmar- 

 giual and stigmal veins short, subequal Pentelicus. 



Marginal vein long, rarely shorter than stigmal; mesoscutum shagreened, with sparse 

 punctures Ph.exODISCUS. 



CHALCASPIS, new genus. 



Female. — Body very short and very stout; Lead very thin antero- 

 posteriorly, very broad (laterally); eyes loDg oval, very widely sepa- 

 rated, faintly hairy; face very convex, not furrowed; occipital border 

 very sharp; genal sulcus distinct, widely open at eye border; ocelli 

 indistinct, at the corners of a very obtuse angled triangle, lateral ones 

 near the eye border. Antenna^ inserted at border of mouth; scape 

 slender, not broadened, rather short; tiagellum rather longer than 

 scape; first funicle joint shorter than pedicel, remaining funicle joints 

 not longer than wide; club large oval, slightly obliquely truncated, as 

 long as all funicle joints together. Pronotum nearly covered by occi- 

 pital border of head. Mesoscutum very short. JMesoscutellum long 

 and broad, twice as long as scutum, nearly flat, rather pointed, with 

 entire border emarginate; axillar sutures very indistinct, axilla^ meeting 

 at tips. Abdomen very short and broad. Legs stout. Wings short 

 and broad; submarginal vein reaches costa at about one-half wing 

 length; marginal vein lacking; stigmal long, curved; radial angle nar- 

 row ; postmargiual as long as stigmal. 



CHALCASPIS PERGANDEI, new species. 



Female. — Length, 1.3 mm.; expanse, 3.4 mm.; greatest width of fore- 

 wing, 0.59 mm. Punctation of head (except the smooth occiput), meso- 

 cutum, and mesoscutellum nearly uniform throughout, the punctures 

 round, lengthened somewhat posteriorly on scutellum; tegulai smooth, 

 with a shallow fovea at inner base; mesoj)leura finely shagreened; rest 

 of body smooth. Funicle joints of antcnnsp short, all broader tbau long, 

 increasing in length and breadth from 1 to 0. Head, pronotum, and 

 mesonotum greenish or coppery in color, with strong metallic reflec- 

 tions; eyes dark red or black, mandibles black; antenual scape honey 

 yellow with black bulbus; pedicel and club dark brown or black; 

 funicle joints honey yellow, joint 1 darker than the others. Pleura 

 and abdomen metallic with greenish or' bluish luster. All coxte metal-
