10 PROCEEDINGS OF THE NATIONAL MUSEUM. vol.65. 



It is possible that this is the true Z>. correhiodes Felder as his 

 figure shows some black at base of fore wing, and it w^ould be neces- 

 sary to examine the type ; should this prove to be the case I suggest 

 the name of D. feldcri for the race from Colombia and Panama 

 which usually goes under the name of T>. correhioides ,' it differs in 

 having no black spot at base of fore wing, the lateral line on abdomen 

 much shorter, not reaching beyond middle of abdomen, the legs black 

 with the base of tarsi and coxae yellow. In collection from Merida, 

 Venezuela, and Panama. The race found from Costa Kica to 

 Mexico has all the coxae black and for this I suggest the name of 

 D. emerita. 



MACROCNEME EUPHRASIA, new species. 



Male. — Antennae black tip|)ed with white. Palpi fuscous black, 

 laterally white at base. Head black; frons with lateral white spots; 

 some white irrorations on vertex. Collar and thorax black; tegulae 

 with metallic golden green scaling and white lines on dorsal and 

 lateral edge; thorax mottled with golden green and a similar streak 

 on patagia. Abdomen above golden bronze; basal segment with sub- 

 dorsal black patches containing a white spot ; sublateral wliite spots 

 on two basal segments ; underneath black with transvei-se green bands 

 and ventral white spots except on last two segments. Legs black, 

 white points on coxae; hind tibiae with wliite fringe at tips. Fore 

 wing fuscous black; two white points at base; some golden green 

 scales on base of costa, a broad streak below cell on basal fourth, and 

 a streak along inner margin to beyond middle. Hind wing fuscous 

 black, faintly tinged Avith blue black; a white spot at base of cell. 

 Fore wing below with golden green irrorations on basal half of 

 costa, in cell to beyond middle and a streak below cell; some white 

 hairs at base of median, and a blue white line on submedian medially. 

 Hind wing below with a golden green streak on costa and one in cell. 



Expanse. — 35 mm. 



Hahitat. — Potaro River, British Guiana. 



Type.—Q'At. No. 25887, U.S.N.M. 



This species comes nearest M. lades Cramer, which has only a 

 golden green spot at base. 



The species identified by Hampson as lades is quite different and 

 must stand as M. leucostigma Perty. 



PSEUDAETHRIA, new genus. 



Male. — Proboscis fully developed; palpi upturned reaching vertex 

 of head, smooth, the third joint short; antennae bipectinate with 

 short branches dilated at extremity, the apical part serrate ; abdomen 

 slightly constricted at base, the last segment wuth lateral tufts. Fore 

 wings normal, the outer margin oblique; vein 2 from just beyond
