NOTES AND OBSERVATIONS. 255 



The only note on the larva of P. lipsiana that I can find is in 

 Barrett, ' Brit. Lep.,' x, p. 234, which reads : " Larva green with 

 brownish head ; feeds upon Vaccinium vitis-idaa in Julj^ other 

 authors say upon birch and wild apple." 



The larva? are to be found at Eannoch on V. viijytillus and 

 V. vitis-idcea, perhaps most frequently upon the former ; they are 

 apparently generally distributed upon these plants, I obtained 

 about two dozen, with a much larger number of P. maccana, 

 one afternoon in the Black Wood, and three or four dozen on 

 some hillocks around the house at which I stayed at Cam- 

 ghouran ; this was situated immediately to the west of the Black 

 Wood. One larva was discovered on Calhina vulgaris whilst 

 searching for those of P. mixtdna, which were common. This 

 larva when offered C. vulgaris and V. myrtillus immediately took 

 to the latter. Probably, like so many of the Peroneas, it will, on 

 necessity, feed upon various plants, but I did not breed a single 

 example out of the hundreds of iarvse I obtained upon Myiica gale. 



The larva spins the leaflets of a spray of Vaccinium to each 

 other, forming a tube similar to that of P. maccana, in which it 

 lies concealed, but in the case of the present species the tube is 

 considerably longer — in some cases it has a length of two or 

 three inches. In confinement it is particularly irritable, resenting 

 the presence of other iarva3 of the same species, and if interfered 

 with in its tube by one will vacate it. When I first had a stock 

 I ke})t them rather crowded in a glass-top tin ; under these con- 

 ditions a number were continuously wandering about without 

 feeding. I afterwards came to the conclusion that unless each 

 had a separate spray in which to form its tube, and the entire use 

 of that tube without molestation, they would not thrive. When 

 they had plenty of room they were quite content, but the result 

 of the earlier crowding was that many of the moths bred were 

 not full size. 



P. lipsiana is distinctly a later species than P. maccana. My 

 first moth emerged on August 19th and the last one on September 

 4th. A series of two dozen examples was bred. I should give 

 the second half of July as the time for the larva to be full grown. 



(To be concluded.) 



NOTES AND OBSEEVATIONS. 



Dragonfly at Light. — In the ' Entomologist,' 1895, pp. 62 and 

 314, 1 have recorded a few species of Neuroptera taken at light by me 

 during that and the preceding year. Certain Trichoptera are 

 common in such a situation, but I cannot recall noting any of the 

 Odonata at artificial light ; nor, I think, does Mr. Lucas mention such 

 an occurrence. Consequently I was most surprised to see and hear 

 a great .Esclina cyanea careering around the dining-room lamp here 

 just an hour after dusk on August 20th, 1919. — Claude Morley ;
