Some apparently neiv Species and Forms of Noctuidae 227 



42. Parallelia subacuta Beth.-Bak. juncta subsp. nov. 

 $ ? , 46—52 mm. 



Averages slightly smaller than typical subacuta ; a little darker in 

 tone above and beneath. Differs chiefly in the reduced breadth of the 

 medial pale band on the fore wing, the basal and postmedial dark 

 patches being sometimes united behind the middle of wing in subacuta 

 juncta, the antemedial line being usually more excurved and a little 

 more oblique in this form than in typical subacuta. The postmedial 

 line is usually a little more strongly bent outward behind costa, and 

 rather more excurved about M 1 (more as in joviana Stoll) in subacuta 

 juncta than in the type-form. 



Manusela, 6,000 feet, October — December, 1919, ten $ $ , six 2 ? ; 

 also one $ , 4,600 feet, January, 1920. 



Both the typical form and the Ceram race of this species vary con- 

 siderably, but in the Ceram race the medial band almost invariably 

 narrows a good deal towards the middle, whilst in the New Guinea 

 form it appears always distinctly broader than in the majority of Ceram 

 specimens. 



DIPTHEKINAE. 



The name Mominse employed by Hampson for this subfamily rests on 

 the acceptance of ludifica as " first species " type of Moma. According 

 to generally accepted rules of nomenclature the type of Moma appears 

 certainly to be alpium Osbeck (fixed by Lederer in 1857; Acronyctinae). 

 Latreille first characterized the genus Diphthera (as Dipthera, Nouv. 

 Diet. Hist. Nat. xxiii, 20 [1818]), describing ludifica and aprilina ; 

 H — S., restricted to ludifica L. (Syst. Bearb. II, p. 176 [1843—5]) 

 which becomes the type of Dipthera Latr. The genus " Dipthera " of 

 Hampson thus becomes Panthea Hbn. 



43. Trisuloides trigonoleuca sp. nov. 



$ 56—58 mm. 



Head, thorax, palpus and antenna ochreous-brown with some 

 white intermixed, tegulae tipped with white, patagia banded with dark- 

 brown ; abdomen brown, tinged with ochreous, the anal tuft pale 

 ochreous ; pectus, legs and abdomen beneath brownish, paler in one 

 specimen than in the type. 



Fore wing ochreous-brown shaded with dark-brown and irrorated
