NOVITATES ZOOLOGICAE XXIV. 1917. 391 



33. Cyllopoda gibbifrons spec. nov. 



(J, 32 mm. ; 9, 37-39 mm. Face (especially in the S) even more strongly 

 protuberant than in postica Walk. (List. Ley. Ins. ii. 371) ; black above, becom- 

 ing pale below. Orbital rim white, mixed with a few yellow scales. Palpus the 

 same, with third joint and part of upperside of second joint blackish ; rather 

 short, with third joint rather small. Antennal pectinations much shorter than 

 in postica — less than twice diameter of shaft. Crown black. Thorax and 

 abdomen above black ; tegula with a yellow spot in front. Breast white, mixed 

 with j'ellow. Abdomen yellow on side, white beneath. Legs predominantly 

 grey to blackish ; hindleg in J whitish, the tibia with a pair of very short, very 

 thick terminal spurs, tarsus at least half as long as tibia. 



Foreu'ing with areole double ; bright gamboge-yellow ; the black costal 

 border in <J 15 mm. broad, in ? 2 mm. ; in addition, a few scattered black scales 

 behind this and nearly always a blackening of vein M ; the usual black distal 

 region and enclosed yellow spot, the latter ciuite narrow at C, \videning rather 

 rapidly, entering the cell, but not deeply, ending at M' ; apical fringe white. 



Hindwing with the black border in both sexes on an average a little wider 



than in postica, narrowing rather suddenly at tornus. 



Underside similar, the distal border of the hindwing in cJ shghtly narrowed.

In posiiui Walk., apart from the above-mentioned distinctions, the black 

 distal border of the forewing bends obUquelj' inward at hindmargin, which is 

 not, or scarcely, the case in gihhifrons. Like postica Walk., latiflava Warr. (Nov. 

 ZooL. xii. 312), and a few others, this species is intermediate between true 

 Cyllopoda and Flavinia *), agreeing with the former in the double areole, with 

 the latter in the less elongate palpus. Perhaps all form a single genus ; com- 

 pare variability of areole in the following species. 



34. Cyllopoda expansifascia spec. nov. 



(J, 39 mm. Similar to latiflava Warr. (Nov. Zool. xii. 312). Palpus, as in 

 that species, with third joint rather short. Antennal pectinations shorter than 

 in latiflava — scarcely twice diameter of shaft. Hindtibia with strong ochreous 

 tufts. Abdomen beneath yellowish white. 



Forewing with areole generall}' double ; coloration as in latiflava ; the black 

 posterior border proximally reaching, distally just crossing SM^ ; the j'ellow 

 proximal patch less triangular than in latiflava, its distal border more oblique, 

 rounded rather than angled where it meets the costal border at SC, rounded 

 also at its outer end (between M and SM') ; the transverse black band in conse- 

 quence expanding strongly, though gradually, anteriorly and rather abruptly 



posteriorly ; distal yellow patch moderately broad. Hindiving with the 



black distal border slightly broader than in latiflava, above extending a little 

 way along costal margin, beneath running narrowly along this margin halfway 

 to base ; abdominal margin above and beneath narrowly black in distal half
