at the first moulting, with drawings ilh 

 the hab tlie larva, whether solitary or ous, 



whether a day <»r night feeder; the ichneumon para 

 and their mode of attack. Specimens of larvae in the dif- 

 ferent moul tings should be preserved in alcohol. The ap- 

 pearance of the larvae when full-fed, the date, number of 

 days before pupating, the formation and description of the 

 •on, the duration of larvae in the cocoon before pupation, 

 their appearance jus! before changing, their appearance 

 while changing, and alcoholic specimens of larvae in the act, 

 Bhould all be studied and noted. 



3. Date of pupation; description of the pupa or chrysalis; 

 duration of the pupa state, habits, etc.; together with al- 

 coholic specimens or pinned dry ones. Lepidopterous pupae 

 Bhould be looked for late in the summer, or in the fall and 

 Bpring, about the roots of trees, and kept moist in mould 

 until the imago appears. (Many Coleopterous pupae may 

 also occur in mould and. if aquatic, under submerged ■-' 

 and stones, and those of borera under the bark of dee.,

l. hate when the inseel escapes from the pupa, and 

 method of escape; duration of life of the imago; and the 

 number of broods in a season. 



Drawing Caterpillars.- Alter some practice any one can 

 make a recognizable drawing of even an insect, especia 

 a caterpillar, and alter a little experience even a -ketch in 

 water-colors. Drawing in natural history is all-important 

 to the beginner; it trains the eye to obsen . and 



good sketches of the early stages of insects are espe< 

 needed in this country. Various cameras have 1 

 to enable the artist to get a correct outlin< oi ts, while 



for Hat. microscopic objects the use of the camera lucida is 

 invaluable; after a few trials it can be nsed or draw- 



ing outlines and filling in details. In this way the larva 

 of the Micro-lepidoptera mounted on gla s ma; 



drawn.
