New Geometridae and Dioptidae in Joicey Collection 261 



14. Problepsis plenorbis Prout $ . 



This fine species was described (Nov. Zool. xxiv, 309) from a unique 

 ? in the Tring Museum. Mr. Joicey has now obtained a good 8 

 from Lebong Sandai, Benkoelen, S.W. Sumatra. This enables me to 

 describe the coloration of the head (lost in the type) and to give the 

 cf characters, which latter show the affinities to be rather with 

 appollinaria Guen. than — as I had suspected — with conjunctiva Warr. 



Face dirty white, in upper half suffused with dark grey, which is 

 strengthened into a large black spot at each side of upper part ; palpus 

 black above, white beneath, with a small intermediate area of brownish, 

 which usurps most of the lower part of the short terminal joint ; crown 

 black, very narrowly white in front ; antennal shaft and pectinations 

 dark brown (distinctly darker than in vidgaris Butl.), the pectinations 

 nearly as long as in appollinaria, extending about to the 38th joint ; 

 8 hind tibia strongly dilated, with hair-pencil, proximal part more 

 strongly fringed than in appollinaria, tarsus less extremely abbreviated, 

 measuring about one-third of tibia. 



15. Scopula elwesi sp. nov. 



$ , 27 mm. 



Face with slight prominence below middle, appressed scaled ; chest- 

 nut with some blackish irroration. Palpus with rather long projecting 

 scales, slightly transitional towards those of Oar; ochreous, streaked 

 with blackish along outer side. Vertex, collar and antenna ochreous 

 with some black scales. Antennal joints somewhat projecting, with 

 slender fascicules of cilia rather longer than diameter of shaft. Thorax 

 and abdomen above pale, with very heavy black irroration, only the 

 abdominal incisions and anal end freer therefrom ; abdomen with a 

 lateral stripe of ochreous, the venter pale, with sparse irroration. Coxae 

 and femora ochreous, with much black admixture on upper and inner 

 sides (the hind leg least so), tibiae and tarsi pale ; hind tibia not dilated, 

 with a pair of well-developed terminal spurs ; hind tarsus not abbreviated . 

 Wings not very broad. Fore wing whitish cream-buff, sparse black- 

 grey irroration (at base denser) ; markings tawny ochreous ; fore wing 

 with some suffusion in proximal half, especially near base ; antemedian 

 and median lines rather straight, the latter enclosing the slightly elon- 

 gate black celldot; post-median from three-quarters costa to beyond 

 two-thirds hindmargin, very slightly incurved between the radials and 

 dentate outward on E 3 and M' ; proximal subterminal thick, nearly
