to be where one pleases, aud to classify by superficial appearance. 

 There are in fact a few species with well-marked apex aud 8 un- 

 mistakeably below it, but most of the obviously allied species have a 

 rounded apex, causiug the termination of vein 8 to be accurately 

 stated only by the word 'iudclinite ' (the present species and the three 

 following are all examples, and tliere are plenty more), and therefore 

 I reject the genus as deceptive. The very strong tendency to round- 

 ing of the apex is perhaps more pronounced in Skuoma than in 

 any other genus of the Tuieina, and it renders all attempts to 

 arrange the species by the relation of the veins to the apex quite 

 useless, though in the case of those species with a distinct apex 

 the position of the adjacent veins should be stated as a specific 

 character. I take the opportunity of noting that in the same paper 

 Stenoma Ounni Busck is a synouym of Aataeotricha fascicularis 

 Zell., Stenoma maroni Busck a synonym of salutaris Jiutl. and 

 IStenoma iihoehe Busck a synonym of reductella Walk.
