TORTRICINA. 149 



A. subaurantiana. The anterior wings are pale yellowish 

 orange, sometimes drab, with slight indications of darker mark- 

 ings with silvery streaks or dots, very rare : the specimen in the 

 Stephensian Cabinet at the British Museum was captured at 

 Darenth Wood. It is also in the Cabinets of Messrs. Edwin 

 Shepherd, William Machin and others. 



The imago appears in June throughout the metropolitan dis- 

 trict ; it occurs also at Birch and Darenth Woods, in the New 

 Forest, Devonshire, near Dover, in Cheshire, and in other parts 

 of the country ; likewise in the vicinity of Edinburgh and in 

 Ireland. 



Genus VI. DICTYOPTERYX, STEPHENS. 



Palpi twice as long as the head, compressed, porrected horizon- 

 tally, or slightly ascending, approximate, clothed with long scales 

 partly enveloping the apical joint ; basal joint drooping, moderately 

 stout, pyriform, truncate ; apical slender, cylindrical, much longer 

 than the basal, horizontal ; middle ascending, stout, nearly straight, 

 thickened beyond the centre, not quite three times the length of the 

 apical. Maxillae slender, as long as the palpi. Thorax slender, 

 ovate, with a small crest or tuft behind. Anterior wings : length 

 equals twice the breadth ; costa arcuated, obtuse at the base ; apex 

 produced; apical margin entire (in D. Lceflingiana truncate and 

 oblique) ; dorsal margin nearly straight. The discoidal cell is situ- 

 ated towards the middle of the wing, and extends two-thirds its 

 length. The subcostal nervures equidistant, the first inserted at the 

 middle of the subcostal vein. Posterior wings ample ; apex acute ; 

 apical margin concave. Abdomen stoutest in the $ , tufted in both 

 sexes. 



The insects in this genus, as determined by the late J. F. 

 Stephens in the Museum Catalogue, are remarkable for the net- 

 like markings on the anterior wings ; but the structure of the 

 wings themselves differs very considerably, so much so that it 

 has been considered necessary to remove from it one of the 

 Stephensian species (Forskaliana), although, in the markings, 

 more reticulated than the rest of his genus, and to associate it 

 with C. Bergmanniana, which it not only resembles, but bears 

 considerable natural affinity to it. Of the three remaining 

 species, contaminana and Shepherdana are well associated ; but 

 we think that for Lceflingiana another position must ultimately 

 be found; perhaps a distinct genus.
