When we came to pack up our live stock, we found that we had secured eggs of 17 

 «pecie8 and varieties, all that we had tied but three. These three were Grapta Proyrw. 

 A very much worn hibernated specimen was caught on the 9th, and being mistaken for 

 G. Satiirus, was tied upon the wrong food-plant 



rhi/ciode,i N'l/rteiH, tied on Soliddgo as an experiment to see if eggs would be laid. 



LyctBiM Lucia, two specimens got into the folds of the gauze, and were killed by 

 flpidors from the outside. 



Some of our caged females were quite fresh, and as we thought we might get more eggs, 

 sticks were bent over our potted plants, and they were caged and packed away in their 

 basket for travelling Amongst them were G. Mamhm and the form Erlphyle of Coliaa 

 Eunithenu!. This last laid no eggs, and one only was obtained by a process which one of my 

 corres|>ondents calls " Egg laying extraordinary." It consists, simply, of gently pressing 

 the abdomen of a female, which lias died without laying eggs, until one, and sometimes 

 two, perfect eggs are passed through the ovipositor. This method may, I believe, at 

 some time, be useful in securing larvie of rare species. My first female Colian Interior 

 was taken in 1886, and died without laying. I then secured one egg, which hatched a 

 laydays afttrrwards; from not knowing the food-plant, however, it was lost. From a 

 beautiful variety of Pnpilio Turnus I secured two eggs in the same way, both of which 

 hatched. Fertile eggs were also got in this way from Carterncephalus Mandan, (and one 

 of these was the only specimen I got through all its stages to full growth,) and from 

 Coliaa Philodice. 



There are one or two points which should be remembered when obtaining eggs and 

 rearing larvte. In the first place the females should not be left exposed to the direct 

 rays of the sun ; but it will be found sometimes that if a butterfly is sluggish, putting 

 her in the sun for a short time will revive her and make her lay eggs. Confined females, 

 whether over branches or potted plants, should always be in the open air. If females do 

 not lay in two or three days they must be fed. This is easily done. Take them from 

 the cage and hold near them a piece of sponge (or, Mr. Edwards suggests evaporated apple) 

 saturated with a weak solution of sugar and water. As soon as it is placed near them 

 they will generally move their antennie towards it and uncoiling their tongues suck up 

 the liquid. If they take no notice of it the tongue can be gently uncoiled with the tip of 

 a pin when they will nearly always begin to feed. It is better to feed them away from 

 the plant they are wanted to lay upon, for if any of the syrup be spilled upon the flower 

 pot or plant it is almost sure to attract ants. I kept one female Colian Interior in this 

 way for ten days before eggs were laid. When eggs are laid they should as a rule be 

 collected at short intervals. They are subject to the attacks of various enemies — 

 spiders, ants, crickets, and minute hymenopterous parasites. Tliey may be kept 

 easily in small boxes, but do better if not kept in too hot or dry a place. When the 

 young caterpillars hatch they must be moved with great care to their food plant ; a fine 

 paint brush is the most convenient instrument. With small larvae, or those which it is 

 desired to examine often, glass tubes, or jelly glasses with a tight fitting tin cover, are 

 best. These must be kept tightly closed and in a cool place. Light is not at all 

 necessary, and the sun should never be allowed to shine directly upon them. If moisture 

 gathers inside the glasses the top should be removed for a short time. Larvro may also 

 be placed upon growing plants. These can be planted in flower-pots and the young 

 caterpillars kept from wandering, either by a cage of wir« netting, or by, what 

 I have found very satisfactory, glass lamp chimneys. These can be placed over 

 the plant, with the bottom pushed into the earth, and then should have a loose wad 

 of cotton batting in the top. This has the double effect of preventing too great 

 evaporation of moisture and keeping its occupants within bounds. Some larvie 

 wander very much and climb with the greatest ease over glass, spinning a silken 

 path for themselves as they go. When caterpillars are bred in the study it must 

 not be forgotten that the air inside a house is much drier than it is out of doors amongst 

 the trees and low herbage, where caterpillars live naturally. The amateur will require 

 some experience in keeping the air at a right degree of moisture, when breeding upon 

 growing plants. In close tin boxes or jars, where the leaves must be changed every day, 

 there is not so much trouble. An important thing to remember with larvse in jars, is to
