DISSOCTENA, Stgr. 



[PL iv., fig. 21.] 



Dissoctena affinis, sp. n. 



Antennas bipectinate, each of the long pectinations slender and 

 pubescent. Palpi very short, subochreous. Head brownish 

 cinereous. Thorax cinereous. Fore wings with rather straight 

 costa, rounded apex, and oblique (scarcely convex) apical margin : 

 brownish cinereous, with two indistinct paler subochreous costal 

 patches beyond the middle, and before the middle a very indistinct 

 oblique fascia-form shade of the same colour, dilated outwards from 

 costal to dorsal margin ; about three very indistinct subochreous 

 spots on the lower half of the apical margin before the brownish 

 cinereous cilia. Hind wings slightly darker than the fore wings, 

 and with a more fuscous shade owing to the absence of subochreous 

 scaling ; cilia unicolorous. Abdomen and Legs cinereous fuscous. 

 Exp. al. 14 mm. 



Hob. Estcourt (Natal), three specimens (Hutchinson).

The subochreous markings on this plainly coloured 

 species are very indistinct, and probably almost obsolete 

 on some examples, unless taken in fine condition. They 

 seem to constitute a sufficient ground for separating the 

 species from the South European D. granigerella, Stgr., 

 to which it is nevertheless closely allied. 



It seems desirable to subdivide the Tineida of Heine- 

 mann as follows : 



A. Maxillary palpi obsolete. 



1. Fore wings with veins 7 and 8 arising from a common stem out 



of vein 9 = SETOMOKPHIN^E. 



2. Fore wings with veins 7 and 8 not arising from a common stem 



out of vein 9 = EUPLOCAMIN^E. 



B. Maxillary palpi 4 6-jointed == TINEIN&:, 



SETOMORPHIN^. 



SETOMORPHA, Z. 

 [PI. vii., fig. 73.] 



The neuration of Setomorpha rutella, Z. (the type of 

 the genus), is as follows :
