37(5 MOVITATES ZOOLOGICAE XXII. 1915. 



Crambometra geu. nov. 



Face with slight projecting cone of scales. Palpus rather long, heavily scaled 

 above and beneath, third joint concealed. Antenna in S bipectinate almost to apex, 

 with very long branches. Thorax and abdomen slender, not crested. Pectus hairy. 

 Femora glabrous ; hindtibia of c? not dilated, all spurs developed. Forewing long 

 and narrow, costa nearly straight, termen short, curved, oblique ; cell over one-half, 

 rather narrow ; SC free, SC--^ stalked, SC^ approaching SC but not anastomosing, 

 SO*-* stalked from before end of cell, radials normal, M' almost connate with R'. 

 Hindwing ample, apex moderately rounded, termen very feebly concave between the 

 radials ; cell oue-half, DC inbent ; C approximated to cell to beyond one-half, SC- 

 separate from R', R- vestigial, from middle of DC, M' approximated to R^ SM^ 

 long, running to distal margin. 



Type of the genus : Crambometra derelicta sp. nov. 



AfiSnities very obscure, apparently rather a primitive form, perhaps verging on 

 the Oenochromi iiae ; as there seem to be traces of SM' in the hindwing and the fore- 

 wing venation is almost unique in the Geometridae (if we except Perusiopsis AVarr. 

 and the problematical Debos Swinh.) it may possibly even demand ftimily separation. 

 The narrow forewing and very ample, much folded hindwing jwint to a probable 

 position of rest at least as much folded as in Alsophila, while the colouring indi- 

 cates some similarity of habit to Leucania, the Crambiis group, etc. 



127. Crambometra derelicta sp. nov. 



c?, 34 mm. Head, body and legs very pale wainscot brown ; a fuscous line 

 from upper extremity of face across vertex, collar and front of thorax ; some dark 

 shading and spotting on foreleg. 



Forewinq very pale glossy wainscot brown, with sparse but coarse fuscous 

 atoms ; a dark discal dot ; a very slight suggestion of darkening along the fold from 

 base to about one-third and along the radial fold just proximally and distally to the 

 discal dot (chiefly an optical illusion due to the depth of the folds themselves) ; 



fringe long, pale, its proximal half with large blackish dots at the vein-ends. 



Hindwing glossy white, absolutely unmarked ; fringe with weak dark dots. 



Forewing beneath with slight smoky suffusion (strongest at base of costa), 

 fading out at about three-fourths, distal region whitish, fringe nearly as above. 



Hindwing beneath white, some slight suffusion and irroration in anterior 



part. 



S. Africa : Tongaat, 1900 (H. C. Burnup). Type in coll. L. B. Prout, sent by 

 the Natal Museum, which I understand possesses tojwtypes. 



128. Hebdomophruda diploschema sp. nov. 



?, 31-32 mm. Head and palpus grey, mixed with brown ; face more brown. 

 Antenna with slender pectinations about twice as long as diameter of shaft. Thorax 

 grey, above mixed with brown. Abdomen grey, mixed with brown and blackish, a 

 rather conspicuous dark dorsal belt on 2nd— 3rd segment, an ill-defined dark stripe 

 on side of venter. 



AVinga very narrow, more so than in apicata AVarr. {Nob. Zool. iv. 101) ; other- 

 wise similarly shaped and scaled. Foreiving with SC^ connected by very short 



bar with SC"', ISC' present (as doubtless in the ? of the other species) ; anterior 

 part light brown, darkening distally, along costa more or less strongly dark-spotted
