96 THE .ENTOMOLOGIST. 



eyes are projecling and promiuent ; the tail attenuate and 

 acute. The colour pale brown, with a medio-dorsal black 

 stripe. A specimen which became a pupa on the 23rd of May 

 came out a perfect insect on the 4th of June. I am indebted 

 to Mr. MoncreaflTfor this larva. — Ed/card Neivman, 



Descriplioii, of ihe Larva of Acidalia remutala. — The egg 

 is laid at the end of May or beginning of June, on the pros- 

 trate stalks of Pol}-gonnm aviculare (knot-grass) ; the young 

 larva emerges towards the end of June, and is full-fed at the 

 end of July, when it rests in an arched posture, the head and 

 legs closely appressed together and forming a mass ; when 

 annoyed it lucks in the head and curls iiself into a double 

 ring, and in that unwonted j)osture frequently falls from its 

 food-plant, feigning death. Head quite as broad as any seg- 

 ment of the body, prone, slightly notched on the crown ; the 

 cheeks gibbous, having a few scattered bristles : body very 

 long and slender ; the 2nd, 3rd and 4th segments broader 

 than the rest ; all the segments transversely and regularly 

 wrinkled, and thus divided into numerous very narrow sec- 

 tions ; 10th, 11th and r2tb segments somewhat warty, and 

 emitting scattered bristles. Colour various, sometimes light 

 putty- colour, and every shade between this and dark umber- 

 brown approaching to black : having, through the kindness 

 of Mr. Wright, had the opportunity of examining a consider- 

 able number of examples, i find it impossible to fix on any 

 normal ornamentation, but i may state that the dorsal sur- 

 face of the anterior segments, from the 2ud to the 6th 

 inclusive, is generally paler than the sides and ventral 

 surface ; in the lighter examples there are black markings 

 in pairs down the middle of the back ; but, as before hinted, 

 the colouring is very iuconstant. — Edward Newman. 



Life-hutory of Ypsipeies eltitaria. — The eggs are laid in 

 July, on several species of Salix, S. capraa and S. cinerea 

 being preferred: the young larvae emerge in twelve days, and 

 feed on the sallow-leaves until half-grown, when they hyber- 

 nate : in the spring the larva begins to teed again as soon as 

 the leaf-buds of the sallow expand : it then grows very 

 rapidly, and is frequently lull-fed by the 1st of June: it has 

 a singular and liitherio unrecorded habit of secreting itself 

 in the ^•eed-down of the sallow during the day, and of spin- 

 ning this together in masses : it seems to feed principally
