3. New Geometridae (Lepidoptera) in the South African Museum. 



By Louis B. PROUT, F.E.S.* 



SUB-FAM. HEMITHEINAE. 



GEN. ALLOCHLOKODES, gen. nov. 



Face smooth. Palpus very short, 2nd joint shortly rough-scaled 

 beneath. Tongue vestigial. Antenna in <$ less than one-half forewing, 

 bipectinate to near apex with rather short branches (in 9 merely 

 serrate?). Pectus somewhat hairy. Femora glabrous. Hindtibia 

 in J not dilated, with terminal spurs only. Abdomen not crested 

 Wings with scaling opaque, not glossy. Frenulum wanting. 



Forewing with costa straight except close to base and apex, termeu 

 smooth, oblique, gently curved, tornus not very pronounced ; cell about 

 one half , DC 3 deeply incurved, SC 1 from cell, anastomosing with C, 

 SC 2 shortly stalked with SC 30 , rather steep, anastomosing strongly 

 with SC 1 , R~ from much before middle of DC, M 1 widely separate 

 from B 3 . Hind wing with costa long, apex rounded, termen smooth, 

 moderately convex, straighter posteriorly, tornus moderate ; cell one- 

 half, DC 3 incurved, becoming oblique, C anastomosing with SC to 

 scarcely one-half cell, SC' 3 stalked, E- from well before middle of DC, 

 M 1 rather widely separate. 



Type of the genus : Allochlorodes elpis, sp. nov. 



May be placed between Allochrostes Prout and Xenochlorodes 

 Warr., having nearly the subcostal venation of the latter, the separation 

 of M 1 even wider than in the former, with which the palpus nearly 

 agrees. The anastomosis of C of the hindwing is much less strong 

 than in either, and the shape and facies more suggest the Omphax 

 group. 



1. ALLOCHLORODES ELPIS, sp. nov. 



. 27 mm. Face, palpus and upper and inner sides of fore and 

 middle legs rufous. Vertex and auteunal shaft white. Occiput and 

 thorax above green. Body and legs otherwise dirty white. 



* The types are in the South African Museum.
