attenuated posteriorly, terminal joint distinct or partly concealed. 

 Posterior tibiae fringed with hairs above. Forewings elongate, 

 rather narrow, costa in male simple, slightly arched, apex acute, 

 hindmargin straight, very oblique. Hindwings rounded-elongate, 

 broader than forewings. Forewings with veins 7 and 8 separate, 

 7 running to hindmargin, secondary cell distinct. Hindwings 

 with veins 3 and 4 from a point, 5 very closely approximated to 

 4 at base, 6 and 7 stalked. 



A small genus of rather doubtful affinity, but apparently con- 

 nected with Serieoris by the rootfeeding species of Orthotcenia. 

 The larva is believed to feed in the stems of Jimcus. The species 

 described below appears to occur all over the world, whether 

 introduced or indigenous it is hard to say ; it is at all times very 

 variable, but I do not think the local forms can be maintained 

 as distinct species. It is abundant through Europe, and occurs 

 also in North America ; I have taken it in Ceylon, and it is found 

 in both Australia and New Zealand. 



1. Aph. lanceolana, lib. 



^ ? . 6 J"-9". Head, palpi, antennae, and thorax varying from 

 pale ochreous to ochreous-brown, sometimes reddish-tinged ; 

 palpi variable in length (in one New Zealand specimen extremely 

 elongate). Abdomen elongate, varying from whitish-ochreous to 

 fuscous. Legs whitish-ochreous, more or less suffused with 

 fuscous. Forewings elongate, costa very slightly arched, apex 

 acute, hindmargin very oblique, slightly rounded beneath ; very 

 variable ; pale ochreous, often almost wholly suffused with 

 fuscous, sometimes unicolorous fuscous mixed with reddish- 

 ochreous ; costa generally with numerous very fine oblique darker 

 striguloe ; sometimes a straight ill-defined dark fuscous central 

 streak from base to apex, entire or interrupted so as to form two 

 or three irregular spots, or visible at apex only, or wholly absent: 

 cilia varying from whitish-ochreous to fuscous. Hindwings 

 grey-whitish, slightly darker at apex ; cilia grey-whitish, some 

 times with a darker line.
