NOYITATES ZOOLOGICAIC XXIV. 1917. 29& 



both wings more noticeably darkened, and especially in having a conspicuous 

 black patch on the third and fourth abdominal tergites. 

 Khasis. S S3, in coll. Tring Mu.seum. 



18. Diplodesma mystica spec. nov. 



?, 27 mm. Face deep red, narrowly white below. Palpus twice as long as 

 diameter of eye, third joint as long as second ; red above, white beneath. Vertex 

 white. Thorax and abdomen pale greenish above, whitish beneath. Hindtibia 

 without median spurs. 



Foreiving with termen gently curved ; SC from near end of cell, SC arising 

 after SC, R' stalked, M' connate ; *pale ohve-yellow (probably faded) ; costal 

 edge white ; a fine, not very conspicuous white hne from three-fifths hind- 

 margin, nearly parallel with termen about to R' or R», then curving slightly 

 away from it, but becoming obsolescent ; no terminal line ; fringe whitish. 



Hindwing with abdominal margin fairly long, termen full, very feebly 



bent at R> and inappreciably at R' ; C approximated to SC for a short 

 distance near base, M' stalked ; as forewing, the hne about central, complete, 

 very gently curved. 



Underside whitish, unmarked. 



South Celebes, August— September 1S91 (W. Doherty). Type in coll. Tring 

 Museum. 



Will not fit into any known genus, but in the absence of the 3 I place it 

 in Diphdesma, Sect. IV. (Gen. Ins. fasc. 129, p. 185), into which— assuming that 

 the cJ frenulum is present— it would fall by my Key (loc. cii. p. 13). SC of fore- 

 wing, C of hindwing, and the shape are, however, against this location. 



19. Hemistola malacbitaria spec. nov. 



<?, 27 mm. Face blackish on upper half ; whitish ochreous on lower. 

 Palpus slender, not reaching beyond frons ; whitish ochreous, with some blackish 

 irroration on outer side. Vertex narrowly whitish ; occiput green. Antennal 

 shaft whitish ochreous ; pectinations slender, not long, rather widely separated, 

 becoming very short towards the 20th joint. Thorax and abdomen green. 

 Hindtibia not dilated. 



Forewing with DC not very deeply curved, SC from near base of stalk of 

 SC-', anastomosing moderately with C, R' barely stalked ; light green, almost 

 as in chrysoprasaria Esp., only a shade more bluish; antemedian hne scarcely 

 indicated ; postmedian whitish, quite indistinct, especially anteriorly, appar- 

 ently not crenulate, perhaps slightly more oblique than in chrysoprasaria ; no 



terminal line. Hindtving with termen rounded ; postmedian line cui-ved 



almost as strongly as in dispnrtita Walk. 



Underside scarcely paler ; unmarked. 



Kukli, N.W. India, August 1891. Type in coll. Tring Museum. 



In spite of the colour and the shorter antennal pectinations, this is probably 

 nearer to dispartita than to chrysoprasaria, and I expect the 9 will prove to have 

 non-pectinate antenna.
