does not profess to include more than the full-fed larva, the 

 pupa, and the imago. I hope hereafter I may have more 

 time to devote to the subject, and work out the changes from 

 the egg to the perfect insect. It has been very tantalizing to 

 me this seasoji to have to neglect so many caterpillars from 

 want of leisure for feeding them. And not only this, but my 

 work, requiring me sometimes in the town and sometimes up 

 in the hills, prevents my keeping any living creatures at 

 either place, for they would be sure to be left without food 

 some time or other. 



" I have tried collecting specimens and transferring them 

 to trees in the neighbourhood of my ranch, so that I could 

 look at them without having to keep them in the house. 

 But the results have not been satisfactory ; for the larvae were 

 sure to get full-fed and wander away whilst I was in town. 



"You will see that the Nos. of the species are not consecu- 

 tive ; for instance, Nos. V, VI, VIII, XI, XII, &c., do not 

 appear. This is because I have not all the species in all three 

 stages, having perhaps found only one specimen of the cater- 

 pillar, and kept it to work through the metamorphoses. These 

 species I hope to send you at some future time, if I am 

 fortunate enough to find specimens to complete the series. 



" I have now worked out eighty-three species, and have 

 some pupse now that I am anxiously watching to see what 

 new glory they will produce." 



The present paper includes forty- six species, five of which 

 are believed to be new to science. The total of eighty-three 

 species worked out by the author's own unaided exertions in 

 two or three years whilst busily engaged in laborious pro- 

 fessional duties, compares not unfavourably with the results 

 obtained in the same line of research conducted under the 

 far more favourable conditions of a high official position* 

 abundant help, artistic and otherwise, and (it is not un- 

 charitable to suppose) the smaller amount of high-pressure
