veins lielow the iiiiclilli' : :in o1iscnn> diirk grey linear coll-mavk ; the fascia is 

 ].rerp(led and followed liy jialer bands with no distinct traversing lines ; marginal 

 ;iiea dark grey, the subniarginal line marked in the upper half by pale spots ; 

 marginal line formed of jiairs of ill-defined black sjiots : fringe grey with darker 

 ilividing line, especially beyond the vein-ends. 



Uintlwinqs: smoky grey, with similar lines to the forewings, but all less defined. 



Underside of forewings dull pale grey, with outer band of central fascia and 

 marginal area, esiiecially in the upjier half, dull blackish : the snbmarginal line 

 marked by pale spots throughout; the baud beyond central fascia distinctly pale 

 grey ; hindwings paler, the outer band of central fascia formed of three crinkb'd 

 lines ; cell-spots of both wings blackish. Head, thorax, and abdomen grey dusted 

 with darker grey.

One cJ, 1 ?, from Ibarra, Ecuador, May and .Tune 1807 (Rosenberg). 



Extremely like //. .^tremwria Wlk., from which it is distinguished by the 

 entire absence of the green tinge above, and of the ochreons ground-colour below ; 

 the cell-spots on the underside are both small, while in strenuaria they arc large, 

 black, and conspicuous. The folil on the inner margin of hindwings is slight. 



Ts. Hammaptera constricta sp. nov. 



Fomriiu/.s: white, with grey dusting; the lines fuscous grey, tlie darker 

 shades tinged with dull reddish or brownish ; basal i)ateh rather large, its edge 

 curved from one-third of costa to one-third of inner margin, crossed near base 

 by a darker band edged by two dark lines ; a narrow grey-dusted band with darker 

 central line precedes the central fascia, which is narrower than usual, especially 

 from vein 2 to inner margin, where the edges are vertical and parallel ; the outer 

 edge forms two teeth between veins 2 and 4, a small tooth on vein and a sinus 

 beyond cell : the dark cell-mark lies in a pale grey space; the central fascia is 

 followed by a broad pale band, traversed by a grey line, and edged outwardly 

 by a blackish line angled outward at vein ; apical space filled up with reddish 

 fuscous (the apex itself remaining greyer), through which the subniarginal line 

 is obscurely visible ; all the markings beyond the central fascia become obsolete 

 below vein 4, the anal sjiace being whitish without lines ; a dark marginal line 

 interrui)ted by pale dots at the vein-ends ; fringe ochreons whitish, chequered with 

 dark beyond the veins in tlie njiper half of wing. 



Ilnulinnt/s : ochreons whitish, witli interrupted dark marginal line and shade ; 



fringe white. 



Underside ochreons white, with cell-marks and marginal line in both wings ; 

 forewings with the outer band of central fascia, and the ai)ical area, except the 

 extreme apex, blackish, the former as far as vein 2, the latter only reaching vein 4. 

 Head, thorax, and abdomen ochreons whitish ; collar and thorax much mixed with 

 brownish grey, the abdomen more ochreons ; palpi externally pale brownish. 



Expanse of wings : 3o mm. 



One (J from La Soledad, Entre Rios, Argentina. 



Very much like some forms of Epivrlio'e emberizata Guen., but without any 

 green tinge and with the central fascia of forewings much narrower. The abdominal 

 fold of hindwings is only slightly marked and fringed towards anal angle with 

 ochreons hairs like the rest of the underside.
