an egg, a fully developed young larva. On one occasion 

 the young larva seemed accompanied by a shred of mem- 

 brane that attached it to the leaf. Another larva apparently 

 had to free its legs from some membranous matter. But 

 on all other occasions, we could be sure of nothing in the 

 way of membrane or egg-shell accompanying the young 

 larva. 



The young larvae were close on 2 mm. in length, were 

 placed with their anal extremities to the leaf and 

 remained in that position, with head depressed, and legs 

 appressed to the body, for perhaps a minute. Very 

 quickly, however, the young larva was moving about, and 

 within the hour had eaten a small circular hole in the leaf 

 on which it was laid. The larva at first was quite white 

 and colourless, and to a great degree transparent. The 

 coloured parts being the jaw- tips, the six eye-spots, and 

 the nine pairs of spiracles. It assumed the normal black 

 colour in a few hours, in a closed box. I did not ascertain, 

 but believe it does so more rapidly exposed to light and air. 



The parturient female is expanded to considerable 

 dimensions, tne elytra failing by a considerable distance 

 to cover the abdomen. She Jays from three to six or even 

 more young at a time, or at least at intervals of a few 

 minutes, and does this once or twice a day, but not every 

 day, for a number of days. One specimen, for instance, 

 laid larvse from July 4 (or before) till July 26th : on the 

 8th it laid six; by the 13th it had laid eleven more; by 

 the 15th, seven or eight more ; 18th, six more ; 20th, one ; 

 22nd, seven ; by the 26th, eight more. Altogether I 

 separated twenty individual females with similar results. 



These observations of separate beetles were begun on 

 July 7th with beetles that had already deposited some 

 larvae. One beetle from this date to the 26th (19 days) 

 deposited 57 larvae, another 56, and another 43 in the 

 same period ; these beetles were noted as large. Of two 

 slender ones, one laid 11 larvae up to the 22nd and 

 then ceased ; the other laid 43 by the 22nd and then 

 died ; a greatly expanded beetle laid 37 by the 26th and 

 then ceased. That was the last date on which any 

 observed beetle laid any eggs. Though the beetles were 

 previously ill-used in the matter of being kept in the dark 

 or nearly so in very small boxes (some in pill-boxes with 

 glass lids, others in tins), they were supplied with plenty 

 of food.
