PRACTICAL HINTS. 199 



24. — The larvtc of lUicenlntrix cidardla are to be found iu 

 Se})tenil)er, on Icavt's oi" alder. They sjjin thin ril)l)ed cocoons on the 

 stem. 



25. — The hirviu oi" (It'li'diin frijiarflln feed between united oak 

 leaves, at the end of Au<i;ust. They are not uncommon on scrubby oak 

 bushes, in lanes near Waustead. 



20. — Lyonetia I'lcrckelld feeds on apple, ])ear, hawthorn, mountain- 

 ash, Itireh, sallow (X. aiprca) and Cofoiicdsfcr alJinis (Fletcher). 



27. — Lyonctid padifortclla turned u[) at Worthiut;' in some plenty 

 in 18!».'i, feediiiii,' on apple, ('(doneastcr njfi)t is and l'raiu(s japonica 

 (sinensis) in Au<''iist-Septendjer. On ap})le, the larvtc patronised tiie 

 topmost leaves of the shoots of the year. The lepidopterist, therefore, 

 should not summer-prune his a]j])le-bushes (Fletcher).

:r510TES ON LIFE-HISTORIES, LARViE, &c. 



On the dipfkrentiation of the larvae of Tepiirosfa bistortata 

 AND T. BiUNDULARTA. — I havc read Mr. liacot's notes on the larvie of 

 T. bistortata and T. hiitmlularia with much interest. I missed his 

 point by directing- attention es}tecially to the end of the stadia in 

 which the inverted V is present when the larvte are more nearly full- 

 fed. I have examined larvte i)reserved in spirit directly after the 

 ecdysis, in which the V tirst apjjcars, and some broods at;"ain this year, 

 and from such, toyether with t>'eneral recollection, I think Mr. Bacot 

 has been successful in findin<>' a true dift'erence lietween the larvi\3 for 

 that ])eriod of development, i.e., the earlier jiart of the stadia in which 

 the mark is ])resent. As he st.ates, the dittereuce between the open and 

 closed V is then very well detiued, and the few exce]itious met Avith 

 are capa})le of ex}>lanatiou. Perhaps some entomologists who take 

 T. hiurnhdaria in the southern counties, other than Somerset and 

 Sussex, will examine the character on the first o])])ortunity, and note 

 whether anv exce]»tions are ])resent iu their broods. — "W. 8. RiuiNiJ, 

 M.I)., F.F.S., Puekerell. J»/// Itl,, 18<»,S. \JS\r. J>n,ut tells us that 

 one of the ))roods which he examined ((Difc, p. 177), and which entirely 

 confirmed j\Ir. Bacot's observations, was from West Wickham, Kent.

Emergence of tue l.\rva of CirrH(Rdia xerampelina from the egg. 

 — On the 27th of November last, five larvrc of C. xt'ramjHiina emerp;cd 

 from the o'^q, eleven others following them on the 2Hth. The box in 

 which the ep;fi;s were placed was kept out-of-doors, but protected from 

 the wet. The parent moth was captured at Everinghani, East York- 

 shire, during the last week of August last, by Mr. J. Sumner. So 

 little is known of the hybernation of this species that every scrap of 

 HI formation is valuable. — W. Hewett, 12, Howard Street, York. 



HvHERNATiNr} LARV.E. — Acidalia citiutaria and //. anrsata. — P)Oth 

 raised from eggs. The larv.-c feed on knotgrass, well. They begin 

 hybernating in August, and eat nothing until spring. They were 

 kept in a cool place, l)nt A. anrsata will hybernate ipute completely 

 even if kept in a warm greenhouse.
