262 Mr. Warren on the Piivdlulina rollected 



Walker erected into the genus Iza. In his preHminary 

 remarks on the family Siculodida in general, Guenee 

 states (Ann. Soc. Ent. de France, ser. v., vol. 7, 1877) 

 that they are entirely destitute of a frenum. This is 

 certainly not the case. In the three specimens of Iza 

 nebulosa it is quite plain and strongly developed, heing, 

 as usual in the ? , divided into three branches. It is 

 also present, though liner and less conspicuous, in the 

 $ of Siculodes rhomboidea. In the fore wing the costal 

 nervure is armed at its base with a large curved tuft of 

 scales, but this is quite distinct from the loop further on, 

 which is clear enough. Along the centre of the cell 

 beneath is a double row of short, curved, glistening 

 hairs. 



46. Siculodes rhomboidea, n. s. 

 Fore wings glossy ocbreous, mottled with darker, and with brown 

 markings ; these form two narrow curved fasciae near the base, 

 which coalesce on the inner margin ; an irregular central fascia, 

 narrow on the costa and inner mai'gin, where it approaches the 

 two basal fasciae, broadening out into an angle towards the apex, 

 where it joins an angulated narrow submarginal fascia ; in it at its 

 widest part are two or three brown flecks ; extreme apex lighter. 

 Hind wings ocbreous with darker mottlings, with three irregular 

 dark brown fasciae, honeycombed with paler ; in the paler space 

 between the central and submarginal fasciae is an isolated brown 

 spot. Apex of the hind wing prominently blunt. Head, thorax, 

 and abdomen mottled light and dark ocbreous. Fringes dark. 

 Expanse of wings, 32 mm. 



One ? . Laranjal, E. Manhes, May 5th, 1874. 



The species belongs to Guenee's second group, in 

 which the palpi are upcurved, the terminal joint fully 

 as long as the second, erect and narrow, the top of the 

 second joint even reaching as high as the summit of the 

 head. The fore wings are narrow and elongated, and 

 the hind wings have the apical angle prominently but 

 bluntly produced, with the hind margin beneath it some- 

 what indented.

47. Iloterodes nervosa, n. s. 



Fore wing white, semidiaphanous; with the nervures fuscous, 



and with some fuscous furry scaling along the nervures towards 



the base of the wing ; costa broadly wliite to the apex ; hind wing
