New Geometridae and Dioptidae in Joicey Collection 259 



2 . 28 mm. Bather larger, third joint of palpus very long. 



"British Guiana." Allotype ex coll. Druce. 



The British Museum has a ? aberration from La Chorrera, 

 Panama, April 1 to May 15, 1898 (C. H. Dolby Tylor) with the 

 cellspot of hind wing nearly filled with black. 



Both this and renistigma belong to the urcearia group, with M 1 of 

 hind wing closely approximated at its origin to B 3 . 



12. Ptochophyle definita sp. nov. 

 ? , 25 mm. 



Face almost entirely overlaid with red. Palpus very short, ochreous 

 on inner side, red on outer. Vertex ochreous, weakly overlaid with 

 reddish. Antenna ochreous, above strongly reddened proximally. 

 Thorax and abdomen pale ochreous, somewhat irrorated (above 

 strongly suffused) with red. Legs strongly mixed with red, fore leg 

 on inner side almost wholly red. 



Fore wing not broad, termen straight and not very oblique from 

 apex to M 1 , very oblique from M' to tornus ; yellowish ochreous with 

 coarse red irroration ; a rather broad chocolate costal margin, triangu- 

 larly expanding a little at origin of median line, gradually narrowing 

 to apex, being bounded by SC 4 ; antemedian line thick and chocolate 

 coloured in cell, where it is slightly oblique outward, posteriorly 

 slender and red, sinuate inward at fold, oblique outward to hind- 

 margin ; median line deeper chocolate, almost blackish, very straight 

 and firm, arising just proximal to the cellmark, somewhat oblique 

 inward to hindmargin proximally to the middle, continued across hind 

 wing, reaching abdominal margin somewhat beyond the middle ; cell- 

 mark elongate, equally dark ; postmedian reddish, arising at about two- 

 thirds, mixed with chocolate anteriorly, slightly angulated outward at 

 B 1 , lost at M\ reappearing more proximally behind M 1 near its base and 

 running irregularly and indistinctly to an oblique darker mark at hind- 

 margin near tornus ; a highly sinuous dark chocolate line from five- 

 sixths costa, oblique outward, thickened at B 2 , merged with the 

 terminal between B 3 and M', reappearing as an irregular tornal 

 triangle with thickened apex and a spot of the ground-colour at its 

 base ; terminal line dark chocolate ; fringe olive-grey, at base reddish 

 chocolate. Hind wiug with termen strongly gibbous, the projection 

 at B 3 to M 1 somewhat accentuated by an otherwise scarcely noticeable
