2(12 TiTE entomologist's keoorh, 



powder was Ijlown into the burrows of tlie larva\ " The burrows 

 liollowed. by each larva cross, more or less, those formed by other 

 larva?, contamination seemed therefore, a priori, to be easy, first by the 

 diffusion of the infected spores and then by the contact of healthy 

 with diseased larv;e. In fact, in one week, of the larvae contained in 

 the tree experimented on, 15 in number, 12 were found infected and 

 dead or d3'ing." The results of this experiment might make it worth 

 while for the Americans to give the plan a trial, in the case of 

 Zeuzera pyrina, which is giving some trouble over there. 



One of the best known collections of Fen Lepidoptera, that of Dr. 

 F. Wheeler, is to be disposed of at Stevens' Sale Eooms on July lOtli. 

 We understand that that of Mr. Farren is to come into the market in 

 September. 



Practical hints. 



On the managejient of the newlv-hatched lakva. — So far as I 

 am aware, no instructions are given \ipon this important subject in any 

 of the entomological handbooks. The plan which has succeeded best 

 in my hands is the following : — I transfer the newly-hatched larvfe, 

 by means of a camel's hair brush, to a small pill-box or glass-bottomed 

 box, place some bits of the food-plant into this, shut up the box, and 

 then put it into a corked or stoppered glass bottle. I tried transferring 

 the larvas to a small bottle with a cork or metal cover, but found that 

 moisture collected on the sides of the glass to sucli an extent tliat 

 many of the larva? were drowned. By the method described above 

 this is avoided, while, on the other hand, the drying up of the food, 

 which occurs if tlie box is exposed to the air, is prevented. — Francis 

 JouN BrcKELL, M.B., 32, Canonbury Sciuare. May \2tli, 189;"). 

 [We shall be glad to hear from others of our readers what methods 

 they find most successful. — En.] 



HOTES ON COLLECTING, Etc. 



('olias edusa at Wimbledon. — Whilst ci'ossing Wimbledon ("ommon 

 on June 3rd, my brother and I saw a specimen of C. edusa. I think 

 the fact worth recording, as I have never seen the species in this 

 locality before. — A. E. Dewey, 3o, Moore Park Eoad, Fulham, S.W.

Notes from the Isle of Man. — Since the 31st ult., sugar has 

 been used by me ever}^ evening at Sulby, and with good results. 

 Several exceedingly fine varieties and striking forms have turned up. 

 llie following are some of the insects taken during the last two 

 nights : — 3 Choerocampa, elpenor (new to my list of Manx Heterocera) ; 

 Acronycta (Viminia) rumicis ; Helotropha leticostigvia ; XyJ aphasia rurca ; 

 Apamea hasilinea ; A. gemina ; A. didyma ; Miana strigilis (very dark); 

 Graiinncsia frigratnmica ; J?usina tenchrosa ; Agrotis segeinm (light and 

 dark) ; Nodiia f estiva ; Hccatera serena ; Brotolomia meticnlosa ; 

 Euplexia lucipara ; Hadena oleracen, H. pisi var. splendens ,- Scoliopteryx 

 Uhatrir. Flowers of the white jjink are yielding Choerocampa porcellus, 

 Ciicidh'a Kiiihratica, Plnsia jiidchriita and P. gamma (hybcrnated and 

 fresh specimens. — H. Shoktridge Clarke, Su11)v Barsonage, Lezavre,
