cellate, roughly fusiform ; 4 moderately clavate, 5 and 6 somewhat broadly 

 united : 3 and 4 Avith long, slender double trichomes, and 6 with a long, 

 slender, single trichome near outer side of apex. 



Prothorax transverse, angles rounded, about 0.6 as long as broad ; surface 

 irregularly transversely striate, minutely and sparingly setose ; about 0.9 the 

 length of the head. 



Pterothorax a little longer than broad, sides of metathorax narrowing 

 towards the base of the abdomen. Legs moderately long, tibiae somewhat 

 more than usually stout. Wings fully developed, reaching to the eighth 

 abdominal segment; setse minute, lower vein of fore-wing more or less 

 regularly set, 17 or more to distal fifth ; upper vein with four or five near base, 

 1 near middle, 1 about distal fourth, and 1 at extreme apex ; costa similarly set 

 with similar weak seta?. Lower cilia of fore-wing wavy, those of hind-wing 

 rather sparse. 



Abdomen elongate-oval, slightly broader than the pterothorax and about 

 0.6 the length of the entire insect, rapidly narrowing from base of segment 8 to 

 tip ; spines on 9 longer than, and on 10 as long as, the 10th segment, which is 

 open above.

THE FOOD-PLANT OF PLATYPTILIA MIANTODACTYLA. 

 BY THE HON. N. CHARLES ROTHSCHILD, M.A., F.L.S. 



In a previous number of this Journal (Ent. Mo. Mag., Ser. II, Vol. 

 XXIV, pp. 159-160, 1913) I stated that the probable food-plant of 

 the larva of Platyptilia miantodactyla was Achillea ochroleuca. This 

 supposition I now have proved to be correct, as both Mr. K. Predota 

 and myself have reared this moth from larvae found feeding on the 

 above-mentioned plant.
