256 New Geometridae and Dioptidae in Joicey Collection 



Underside similar, but with the fore wing slightly darker anteriorly, 

 paler posteriorly, and lacking the white and brown streaks at M. 

 S. W. Protectorate, South Africa, without more exact locality. 



8. Maxates dysides sp. nov. 



? , 42 mm. 



Palpus long, second joint reaching beyond frons, third joint slender, 

 as long as second. 



Similar to macariata Walk. Wings rather broader. Fore wing 

 with termen rather less oblique, not excised between the radials ; 

 distal boundary of the green area less oblique than termen, rather 

 more deeply incurved between the radials ; shadowy (on underside 

 distinct) subterminal band less broad, but continuing (though tapering) 

 to costa. Hind wing with tail rather less long ; distal boundary of 

 green area much less produced at M 1 , blunter ; subterminal band less 

 broad proximally, marked with elongate black (beneath weaker) marks 

 before and behind E 2 . 



Lebong Sankei, Benkoelen, S. W. Sumatra. 



Leptocolpia gen. nov. 



Face smooth. Palpus short. Tongue wanting (?). Antenna in $ 

 bipectinate. Pectus hairy. Femora scarcely hairy. Hind tibia of g 

 dilated, with hair pencil ; all spurs present, rather short, rather approxi- 

 mated. Abdomen not appreciably crested. Frenulum in $ moderately 

 strong, from before basal expansion of hind wing. Fore wing rather 

 narrow, with costa gently arched. Apex acute, termen slightly waved, 

 very slightly subconcave to E 3 , here sharply angled, posteriorly ex- 

 tremely oblique; cell rather less than one-half, DC deeply incurved 

 very oblique posteriorly, SC 1 anastomosing with C, SC 2 ' 5 " 3 " 4 rather long 

 stalked, E 1 about connate, M 1 approximated at base to E 3 . Hind wing 

 with costa rather long, apex rounded, termen waved, produced to rather 

 strong teeth at E 1 and E 3 , with a shallow sinus between them, tornus 

 moderate ; cell less than half, DC incurved, oblique posteriorly ; C very 

 slightly approximated to cell near base, rapidly diverging, SC 2 well 

 stalked, E 2 very characteristic, M 1 approximated to E 3 . 



Type of the genus : Leptocolpia viridicatena sp. nov. 



Differs from Bathycolpodes (which it should precede) in the pectinate 

 antenna, narrower wings, separation of M 1 of both wings, &c.
