CAPTUUFS AND FIELD REPORTS. 65 



two of their Catalogues — " Microscopes " and " Microscope Acces- 

 sories." To entomologists the most important of the contents of 

 the former is a new microscope specially designed for their use, of 

 which an illustration appears on the cover of our December number. 

 In the second catalogue, perhaps the most interesting things from an 

 ordinary working entomologist's point of view are the drawing and 

 measuring appliances. 



Emergence of Eustroma silaceata. — I took a worn female, 

 third week in August, 1909, at Folkestone. She laid about three 

 dozen ova. The larvae fed up on willow herb {Epilohium), pupated, 

 and instead of lying over till May, 1910, the imagines began to come 

 out the second week in October, the last emerging by mid-November. 

 A mating, and some three dozen more ova were obtained. For the 

 larva3 of these there was difficulty in obtaining food supplies, as all 

 but odd bits of Epilohium had by this time perished ; but with the 

 help of some old-fashioned fuchsia this brood also was got into pupa 

 state. They were put in a north porch, but on December 31st an 

 imago appeared, with another on January 1st, 1910, and others 

 followed on by twos and threes. By January 15th, 1910, I had 

 another forty ova. Larvse from these began to hatch out on the 20th. 

 I think I shall be able to feed them upon young growths at the base 

 of the small willow herb growing in the garden. — (Eev.) Archibald 

 Day ; Malvern Link. 



Papilio nireus Fourteen Months in Pupal State. — On Septem- 

 ber 28th and 29th, 1908, five larvte of Papilio nireus pupated, and 

 one attained the pupal state on October 18th ; the other four all 

 went over until August, 1909. On July 24th, 1909, I left Durban by 

 the ' Durham Castle ' for England, and three of the butterflies 

 emerged during the passage on August 11th and 12th ; the remaining- 

 pupa I put in a chip-box, and had it with me all the time I was in 

 London (seven weeks). I returned by the ' Dunluce Castle ' on 

 October 9th, and arrived here with the pupa on November 5th. 

 On November 25th, this pupa produced a small female specimen. 

 Thus, all but three days, it has been fourteen months in the 

 pupal state, during which time it has travelled 14,000 miles, and 

 crossed the Equator twice. This is, I think, very unusual, and I 

 cannot account for the butterfly not emerging, at any rate upon 

 either of the occasions when in the Tropics. I may mention that I 

 brought with me twenty-seven pupge of P. cenea that had pupated in 

 July, 1909, and from all of these butterflies emerged on the way 

 home before we got to Teneriffe. — G. F. Leigh ; Durban, Natal. 



CAPTUKES AND FIELD REPOKTS. 



Luperina gueneei at Southport. — It may be of interest to 

 report that I have in my cabinet a specimen of L. gueneei from 

 Southport (captured by the late Mr. T. Davies, of Birkdale). It 

 exactly corresponds with tig. 3, pi. vii. (Entom. vol. xlii.). Although 

 somewhat worn, it is easily, recognizable, and I have compared it 

 with Mr. Baxter's insects; it most resembles his early captures,
