wise scarce. The best recent seasons for the species were 

 1906 and 1914, when it was abundant. 



I have no early record of the immigrant appearances. 

 Latest observed, October 1st, 1903. 



32. P. atalanta, L. Always fairly common, affecting the 

 Eupatoi'ium cannahinum and scabious. It was in profusion 

 one year upon a small plot of lucerne near the top of " a pass." 



Earliest seen, advena, April 23rd, 1900; latest, October 9th, 

 1914, near Great Missenden. (In Middlesex to October 18th.) 



33. Vanessa io, L. I have never found this species abun- 

 dant ; it was, however, fairly common in a small patch of 

 lucerne, usually devoted to cereals, in August, 1909. 



Earliest seen, after hibernation, April 20th, 1912 ; latest. 

 May 23rd, 1904. Normal emergence, first seen, August 3rd, 

 1899 ; last seen, September 14th, 1908. 



34. Aglais urticce, L. First seen, March 17th, 1906 ; latest, 

 a second generation from larvae found on nettles and bred under 

 natural conditions. First moult, September 12th. All had 

 pupated, September 28th. Imagines from October 12th to 20th, 

 1907, some very dark ; all showing a disposition to hibernate 

 immediately. 



35. Eugonia polijchloros, L. Very rare. I have never found 

 it in the Chilterns, though there are plenty of elms in the 

 villages skirting the Vale of Aylesbury. Mr. Spiller says he took 

 one at sugar in 1893, and saw some others in the western 

 district, that being a year of plenty elsewhere. Not observed by 

 Mr. Peachell (1900) at High Wycombe. Reported from Drayton- 

 Beauchamp by the Rev. II. H. Crewe.

NOTES AND OBSERVATIONS. 



Entomologists at the Front. — Speaking in the House of 

 Commons on Thursday, April 22nd, Mr. H. J. Tennant, Under- 

 Secretary of State for War, paid a high tribute to the splendid work 

 of the Royal Army Medical Corps. All epidemic diseases such as 

 measles or typhoid had been brought under control and localised, 

 and special illnesses to which troops are particularly prone had been 

 either prevented altogether, or treated at so early a stage that 

 recovery had been effected in the shortest possible time. Proceed- 

 ing to explain the precautions adopted against summer sickness, he 

 continued : — " Now that the rigours of winter were giving way to 

 what might be the intensity of summer heat, they were rather 

 apprehensive of a plague of flies and insects, and they had sent out, 

 in order to combat that evil, entomologists of world-wide reputation, 

 who were now engaged in taking such precautionary and preliminary 

 steps as were possible while these creatures were in the larva stage
