Pachycopsis geu. uov. 



?. ForetciiKjs : with costa shuukk'red iit base, tlicii straiglit, ami hardly convex 

 before apex, which is blnutly rounded ; hiudmargiii curved. 



1 Undid lujs: narrow, the inner margin long, and anal angle squared; apex 

 strongly rounded; hindmargin rounded, with a percejitible indentation beyond the 

 cell. 



Palpi slender, porrect, twice the length of head; antennae thickened, with 

 close deep and stout serrations, gradually decreasing to apex; hindtibiae with two 

 spurs, the outer quite short, the inner very long. 



Neurotion: forewings, cell half as long as wing; the discocellnlar concave 

 above, vertical below: (irst median at four-fifths, second before end, third from end 

 of cell; lower radial from the top of the vertical lower arm of discocellnlar; (i, 7, 8, 

 0, 10, stalked; 11 from cell, anastomosing and becoming coincident with the costal. 

 Hindwiugs with the two subcostals from upper end of cell. 



Type : Pachi/copsis tiidentata sp. nov. 



49. Pachycopsis tridentata sp. nov. 



Forewings: very pale green, with three white denticulate lines; the first near 

 base ; the second just beyond middle, jutting out and forming a rectangular jjrojection 

 towards hindmargin between veins 3 and 4; third line submarginal; fringe cou- 

 colorous, preceded by a row of large pale siiots between the veins. 



llindwings : the same. 



Underside whitish green. Head, thorax, and abdomen jiale green; vertex 

 white; antennae ferruginous. 



Expanse of wings: 14 mm. 



One ? from Paramaribo, November 1892 (C. W. Ellacombe)- 



A very delicate species; the specimen is probably somewhat faded, but is 

 certainly much paler green than either of the two small species Sguchlora froiidarin 

 and Aplodes glaucaria of Guen^e. 



Paromphacodes geu. nov. 



Forewings : elongate, widening outwards; costa faintly curved ; apex subacute; 

 hindmargin obli(jue, hardly curved. 



llindwings : with apex strongly rounded, hindmargin nearly straight; anal 

 angle square. 



Antennae of cj shortly bipectinatc, the pectinations stiii' and ciliated; of ? 

 subserrate; palpi porrect; tongue and frenulum present. 



Neurotion : forewings, cell nearly half the length of wings; discocellnlar 

 oblique below; first median at two-thirds, second shortly before, third from the end 

 of cell; lower radial from above middle of discocellnlar, ujiper from up])er angle ot 

 cell or stalked with 7; T, 8, 9, lu, stalked; 11 anastomosing with lli, and 10 with 11 

 or 12. llindwings with the costal straight, gradually diverging from subcostal; 

 the twd subcostals short-stalked: radial from above centre of discocellular; medians 

 as in forewings. 



Type : Paromplmcodes ruhrimargo sp. uov. 



In the African genus Omphacodes the costal of hindwiugs anastomoses strongly 

 with the subcostal for three-fourths of cell.
