concave base. The legs are black, and the claspers ochreous-green 

 with black feet. 



The larva begun to prepare for pupation on July 9th at mid-day. 

 A few of the stalks of the food-plant were connected with ragged - 

 looking threads of silk enclosing the larva. It then placed itself in 

 the centre on a stout stalk, head uppermost, and spun a girting thread 

 below its thoracic segments which passed under the lateral spines on 

 the 1st abdominal segment, and in front of those on the dorsal surface, 

 without making any anal attachment whatever. These proceedings 

 were done in a leisurely manner, and were completed by ten o'clock 

 on the morning of the 10th. The larva remained in this position 

 until the 15th, when it was found to have pupated at 8 a.m., and was 

 now hanging head downwards and suspended at the anal end to the 

 cast skin, which was held in position by the girting thread. The 

 pupa is stout in form at the head and thorax, with an elongated and 

 rather tapering abdomen. Its colour a variegated umber, darker on 

 the wing-cases, and with a wide dark dorsal marking on the thorax. 

 This is accompanied by a wavy, lighter, subdorsal line on either side 

 as far as the 3rd abdominal segment. The spiracles are very strongly 

 marked with dark irregular spots, black in the centre. Projecting 

 from the head are two short cases containing the palpi, with dark tips 

 furnished with minute seta^. There is a subspiracular darkish line on 

 each side, and on the ventral surface of the abdominal segments are 

 broad, dark, brown blotches. — J. C. Dollman, Hove House, Newton

Ecid OF Hemithea sTKKfATA (thy.miaria). — To the naked eye the 

 egg of H. striyata looks like a pale green, shiny, much flattened, oval 

 scale. Under a strong hand lens it is seen to have a regular oval 

 outline ; the length : breadth : height is about 4:3: 1^, rather higher 

 at what one may suppose to be the micropylar end, although the 

 micropyle is not discernible after the power used. The surface 

 appears to be finely pitted, and it thus gets the appearance of having 

 a texture similar to finely woven silk. The upper surface is slightly 

 depressed over the greater part of the area, the sunken oval giving 

 the shiny appearance to the egg when viewed with the naked eye. 

 The eggs are attached firmly by the whole of the basal area. Laid 

 during the night of July 31st, the ? caught the preceding day at 

 Chavoire, near Annecy. — J. W. Tutt. AiKjust 2/a/, 1902. 



SCIENTIFIC NOTES AND OBSERVATIONS. 



Silk mixed with the ova of Tephrosia bistortata. — I am at a 

 loss to explain tlie source of the silk which this species mixes with its 

 ova when laying them. A newly-emerged ? captured on the morning 

 of July 29th on the tree-trunk of a plane tree near Annecy, laid a 

 large number of ova between the upper rim of the box and the lid, 

 during the three nights following capture. The bright green eggs 

 were so thickly covered with and mixed with the well-known short 

 pieces of greyish fiossy silk, as to give one the impression that they 

 must have been laid by the 2 of a woolly- tailed species. I have 

 noticed this before, but have never seen such a free use of the silk as in 

 this instance. I believe the source of the silk has been noted, but I 

 canuoi just now remember where.- J. W. Ti xt. Aiujint 2n(l. 1902.
