RHOPALOCERA MALAYANA. 



Genus LOGANIA, * gen. nov. 



Anterior wings irregularly subtriangular ; costal margin convex, the apex acutely 

 produced, outer margin deeply and concavely sinuate, inner margin nearly straight ; costal 

 nervure extending to near middle of costal margin, first subcostal nervule emitted a little 

 beyond middle of cell, second midway between base of first and apex of cell, third and 

 fourth bifurcating at about two-thirds the distance from end of cell and apex of wing; 

 bases of the first and second median nervules one-third nearer together than the bases of 

 the second and third. Posterior wings elongate, the costal margin nearly straight, the 

 posterior margin deeply sinuate, first subcostal nervule emitted a little before the end of 

 cell ; palpi very long, hirsute, the apical joint slender, but clothed with adpressed hairs 

 {antenna: mutilated) ; legs with the apices of the tibife more or less globosely incrassated, 

 the femora with a few slender spines. 



This peculiar genus, which possesses superficially a Heterocerous appearance, 



is probably found throughout the Malay Peninsula. I have received but one 



Fio.oi.-Postorior specics ; but a second, from Tenasserim, belonging to the Calcutta Museum, has 



^^i^yic^"/'""" been shown me by Mr. F. Moore. Of the species here described female specimens 



have alone reached my hands. 



1. Logania malayica, n. sp. (Tab. XXII., fig. 21 2 .) 



Female. Wings above white ; anterior wings with the costal margin narrowly fuscous and the apical 

 area narrowing to outer angle of the same colour ; posterior wings with the outer margin very narrowly 

 fuscous. Wings beneath white, thickly and irregularly mottled with brown. Body and legs brownish. 



Exp. wings, 2 , 23 to 25 millim. 



Hab. — Malay Peninsula; Sungei Ujong (Godfery and Durnford — coll. Dist.). 



Genus ALLOTINUS. 



AUotimts, Folder, Eeise Nov. Lop. ii. p. 285 (1865). 



"Antennas sensim incrassatse, paullo longiores, quam in Mileto." 

 "Palpi articulo tertio aciculari sat longo, praBsertim in feminis." 



" AlcE antics vena subcostali triramosa,t ramo tertio sat longe poue cellulam emisso vena discoidali 

 superiore e celluL-e clausa nata, venula discocellulari suprema distincta." 



" Pedes sat longi, gracillimi, aciculares, tibiis posticis femora subiequantibus." 



Feldcr's original diagnosis of his genus is here given, as I have neither the Singapore 

 species which he includes in it, nor have I both sexes of any other species of the genus, which 

 is readily separable from the preceding genera by the position of the third subcostal nervule of 

 the anterior wings. 



One species has been described from Singapore, and others from Java, Celebes, and the 

 Philippine Islands, but doubtless many more remain to be discovered and the true geographical 

 range of the genus cannot at present be rigidly defined, though its head-quarters appear to be 

 in the Indo-Malayan region. 



* I have dedicated this genus to my friend and colleague, David Logau, the inspirer and sustainer of this work,
