( .300 ) 



cell-spot of forcwiugs outlined with black, of liiadwings wholly black and louud ; a 

 curved black line at two-thirds on forewings and three-fonrths on hindwings; a brown 

 cloud along hiiidiuargiu of forewings above vein 3. Head, thorax, and abdomen 

 concolorons with wings. 



Expanse of wings : c?, 38 mm. ; ? , 42 mm. 



A ])air from Palma Sola, Venezuela, and a ? from Fort St. George, Trinidad. 



Hindraargin of forewings in ? with a prominent depressed tooth at apex and 

 veins fj and 3, with a slighter one at vein 4 ; of hindwings with slight teeth at all 

 the veins, most prominent at 3, 6, and 7. In the d all the teeth are reduced and 

 blunt. 



In certain cases the brighter ochraceous tint is altogether absent, and the 

 wings take a darker more rnfous brown colonr ; bnt the size and markings remain 

 precisely the same. This form ma}" be convenicntl}' named ab. obscurior. 



A (J from Popayan, Colombia (Lehmann), and a ? from between Manaos and 

 R. Jutahi, on the Amazons (Stuart), both belong to it. The antennae of the S are 

 subdentate, with quite short fascicles of cilia. 



231. Perg'ama plagodiata sp. nov. 



Foreicings : pale straw-colour, traversed by numerous fine ochraceous strigae, 

 which are more dense towards hindmargin; basal patch deeper ochraceous, becoming 

 rich brown on inner margin ; this patch is much smaller than in P. iiohjgonaria 

 H.S., diffusely edged externally and extending much farther along inner margin 

 than on costa ; two pale brown cell-spots, and one or two indistinct dark dots before 

 the upper tooth ; fringe concolorous. 



Hindwings : straw-colour, with the outer third dilFnsely ochraceous, passing 

 into pale brown towards anal angle ; fringe concolorous, brownish towards anal 

 angle. 



Underside yellow-tinged: forewings with outer third slightly ochraceous and 

 with a deeper streak from costa at three-fourths ; hindwings with outer third 

 brownish ochraceous. Head and thorax brown and rufous ; abdomen i)aler, 

 becoming ochreous on anal segments. 



Expanse of wings : 40 mm. 



One S from Cucuta, Venezuela. 



In shape of wings, etc., like F. pohjyonariu; but the colouring and markings 

 remind one strongly of the species of Plagodis Hiib. 



232. Pergama uniformis sj). nov. 



Forewings: grey, with an olive tinge, and finely dusted with dark atoms; the 

 central area darker, brownish olive; first line before one-third of costa, olive- 

 brownish, running obliquely outwards and rounded in cell, then oblique inwards and 

 curved below median to inner margin at i|uite one-third; outer line from costa at 

 three-fourths to inner margin at two-thirds, oblique, slightly bulging in cell and 

 submedian interspace, preceded by a broad olive-brown shade, darker than the rest 

 of the median area, which towards the costa is of the same grey tint as the basal 

 and marginal areas; cell-spot small, white, semihyaline, on the upper half of the 

 discocellnlar ; some oblique olive streaks across the marginal area ; two or three 

 submarginal black dots below apex ; fringe greyish olive.
