202 Mr. E. Meyrick's Descriptions of 



gradually narrowed upwards, second about f, narrowed on costa, 

 anterior edge convex on upper half, posterior somewhat irregular; 

 a suffused orange patch on lower part of termen ; three or four 

 dashes of blackish irroration on veins above this, confluent on 

 apical margin ; a fine oblique white strigula from costa at J : cilia 

 grey, on costa and apex with basal half fulvous-orange and a fine 

 whitish basal line, beyond this with two or three rows of black 

 points opposite apex. Hindwings with 3 and 4 connate; grey, 

 darker on veins and towards apex and termen, basal half hj^aline 

 except veins and a streak through middle of cell ; cilia grey. 



British Guiana, Bartica and Mallali, from January 

 to March {Parish) ; ten specimens. I had unhesitatingly 

 identified this conspicuous insect with poecilosoona , Wals., 

 from Panama, regarding the neural differences as varietal ; 

 but having received through the kindness of Mr. A. Busck 

 two fine examples of the latter species, I find that the 

 characteristic distinctions of marking are unfortunately 

 omitted in Lord Walsingham's description and not shown 

 in the figure (Biol. Centr. Amer. IV, p. 51, pi. ii, f. 11); 

 I therefore redescribe it beneath. The genus is a good 

 one, though the two points on which stress is laid are the 

 very two which are shown by the above species to be 

 unreliable ; it is allied rather to Glyphidocera. 



Zelosyne poecilosoma, Wals. 



(J. 11 mm. Head white. Thorax fulvous, with waved white 

 transverse line before middle and white posterior spot edged an- 

 teriorly with blackish. Forewings with termen obliquely rounded 

 (much less oblique than in olga); 7 and 8 coincident; fulvous- 

 brown, towards tornus fulvous-ochreous ; two broad snow-white 

 fasciae as in olga, but black margins stronger, anterior convexity 

 of second below middle; an elongate suffused white patch, resting 

 on termen below middle ; an oblique white strigula on costa at t, 

 whence a narrow streak of very fine black and white transverse 

 striation runs to termen below apex, costal space above this deep 

 ferruginous : cilia as in olga. Hindwings rather dark grey, basal 

 half hyaline except veins ; an oval prismatic-hyaline tornal patch 

 forming in reflected light an eye-shaped violet-crimson spot edged 

 with pale blue; cilia grey. 



Panama. The distinctive characters of the transverse 

 thoracic line, the white subapical spot of forewings (indi- 

 cated inaccurately in figure), the praeapical striated streak,
