 THE COLLECTION OF MR. H. J. ADAMS, F.E.S. 



By Percy I. Lathy. 



Syntomis sulana, sp. nov. 

 $ . Blackish with a purple gloss ; antennae whitish towards tips ; 

 thorax with lateral crimson patches ; abdomen with only faint indi- 

 cation of crimson on basal segment ; complete crimson bands on next 

 three segments ; terminal segments with bands incomplete dorsally. 

 Fore wing with long wedge -shaped hyaline patch in end of cell ; a 

 larger oblong patch below cell ; an oblong patch above vein 6, and 

 two patches between veins 3 and 5. Hind wing with two small 

 elliptical hyaline spots below cell, and divided by vein 2. 



Hab. Sulla Mangola (type) ; Sulla Besi. 



This species may be distinguished from S. celebesa, Walk., by 

 the two hyaline spots of the hind wing, and from ab. gracilis, 

 Bober, by the abdominal bands being incomplete dorsally. 



Sarosa xanthotarsis, sp. nov. 

 $ . Head and thorax black ; frons and thorax with patches of 

 olive yellow ; thorax at side and legs with patches of metallic blue ; 

 minute metallic blue points on tegulaa ; tarsi completely orange ; 

 abdomen black, with olive yellow patch on first segment and narrow 

 bands on the others ; dorsal and sublateral series of metallic blue 

 spots, and one or two metallic blue spots on ventral surface ; wings 

 yellowish hyaline, the veins and margins black. Fore wing with 

 minute metallic blue basal spot just below costa ; the inner area 

 orange ; veins orange towards base ; the terminal band very wide on 

 apical area, and expanding slightly at tornus. Hind wing with the 

 terminal band expanding between vein 2 and tornus. 



Hab. Venezuela. 



Closely allied to S. sesiiformis, Walk., but may easily be 

 distinguished by the completely orange tarsi and orange inner 

 area of fore wing. 



Cosmosoma rubrobasalis, sp. nov. 



$ . Head black, with metallic blue on frons and vertex ; antennas 

 white at tips ; tegulaa black, with metallic blue points ; thorax scarlet, 

 the patagia rather widely fringed with blue-black ; fore and mid-legs

 except on last two segments, leaving dorsal and lateral triangular 

 black patches containing metallic blue spots ; ventral valve white ; 

 wings hyaline, the veins and margins black. Fore wing with the base 

 scarlet, extending slightly along costa and inner margin ; discocellulars 

 with rather more black than other veins ; terminal band very wide on 

 apical area, and expanding at tornus. Hind wing with terminal band 

 expanding at apex and tornus.
