seen. They are hatched prmcipally between six and 

 nine o'clock in the morning ; and for some little time 

 after emerging from pupa they remain upon the trunk of 

 the tree stretching and drying their wings, when, of 

 course, they are readily taken. If the entomologist will, 

 during these hours, visit the trees frequented by them, 

 he will, with comparative ease, acquire a supply of good 

 specimens. As they are very lively, they must not, by 

 any means, be put into pill boxes, as they would soon 

 spoil themselves, but mixst be pinned at once. At first 

 sight they resemble wasps, but, since they cannot sting, 

 the entomologist need not fear them. 



We will now pass on to that section of internal feeders 

 which live on the pith in the stems of plants. Amongst 

 these is Gortyna flavago, which may be found feeding in 

 the stems of thistles in May and June. The larvae are 

 difficult to rear ; but the species may be successfully 

 bred, if collected in the pupa state. The pupse may be 

 found in those stems in Avhich the larvae last fed. The 

 larvse of Nonagria typlice feed in May and June within 

 the stems of the various species of Reed-mace (Typha). 

 These plants are often termed Bull-rush. The remarks 

 made about the last species will apply equally to this. 



Adapted to their natural habitats, the internal feeders 

 are elongated, and differ very much from ordinary cater- 

 pillars. Allied to them are the larvse of the Hepiulidce, 

 and many of those which feed at the roots of grass and 

 other low plants : these are also diflicult to rear. 



Fresh foi'ms will now continue to appear until the end 

 of September, in which month and the preceding some of 

 tlie most singular may be obtained. Three new examples 

 are now becoming fine. The ver}^ hairy black and orange- 

 coloured caterpillar, Avhich is so often seen running on 

 the road or footpath in sunny weather, is familiar to every 

 one. It changes into the common Tiger-motli (Arctia
