of notata received from the New Forest, or from the bred female of 

 maculicollis. On May 10th, 1914, the last-named was shut up for 

 several hours with the bred male of the same species, but pairing 

 was not observed to take place. Indeed, the insects took very little 

 notice of each other, and, whenever a confrontation took place, the 

 female, especially, manifested great alarm, and at once began to I'un 

 backwards. 



A few details concerning the life-histories of these larvae are 

 appended : — 



No. 1 (? notata). — Obtained at Woking, July 19th, 1913. Continued to feed 

 until October. Provided with a piece of soft wood, December 26th ; rested on 

 under-surface of wood throughout the winter. Found lying on its side, on floor 

 of box, partly coiled up and very inactive, April 14th, 1914. Still showed faint 

 traces of life as late as May 4tli, but expired shortly afterwards, finishing its 

 existence in the larval state. 



No. 2 (maculicollis, $ ). — Collected at Woking, July 28th, 1913. Ceased 

 feeding early in October, and remained resting on its side, in a semi-circular 

 position, on the floor of the box. Ke-examined o\\ October 17th, after an 

 interval of two days, by which time it had movilted and pupated, disclosing the 

 rudimentary wings. On April 23rd, 1914, 6 p.m., piipa quite active and 

 crawling about the box ; by 8 p.m., the final moult had been completed. Imago 

 found dead, July 3rd, 



No 3 (maculicollis, $ ). — Caught at Woking, Jvily 28th, 1913. During 

 October became qviiescent, lying i^pon its side. Re-examined on November 

 2nd, and found to have pupated since last observation, a day or two before. 

 Pupa running about actively on April 23rd, 1914 ; ovipositor noticed for the 

 first time, carried on dorsum of abdomen. Imago emerged between 10 p.m., 

 April 23rd, and 7 a.m. April 24th. Foimd dead, July oth. 



No. 4 {? notata). — Taken at Wisley, Aiigust 4th, 1913. Continued to feed 

 until the end of October, at least. Eemained a more or less active larva until 

 May 4th, 1914 ; during this period of hibernation the larva was, for the most 

 part, resting on the dark under-surface of a large chip of wood. After 

 May 4th, life gradually became extinct, withoiit the final metamorphosis 

 taking place.
