CONCLUDING REMARKS. 353 



nach Mossambiqiie : Zoologie, V. Insecten und M3'riopoden ;" 

 and Walleogren's treatise in the " Kongliga Svenska Veten- 

 skaps — Akademiens Handlingar " of 1857, entitled, " Lepi- 

 doptera Rhopalocera in Terra Caffi-orum annis 183tt — 184:5 

 collecta a J. A. Wahlberg." 



I have also to record my obligations to the numerous sub- 

 scribers (headed by the Colonial Government), who, together 

 with other most liberal contributors towards the expenses of 

 publication, have enabled me to issue this work without 

 pecuniary loss. To them, as well as to the public generally, 

 is due a word of explanation as to the long delay which has 

 taken place in the publication of the Second Part. This 

 has been solely owing to unexpected difficulty in bringing 

 about the completion of the plates, the desciiptive portion of 

 the Second Part having been in print more than two years 

 ago. Vexatious as the delay has been in many respects, it 

 has proved of benefit to the work by affording time for the 

 collection of much fresh material and information, as may be 

 gathered from the list of " Additional Species " and the 

 copious " Additions and Corrections." 



Most gratifying has it been to me, during the progress of 

 this work, to note the increasing attention paid to Entomo- 

 logy both at home and abroad ; and the thought that I have 

 been instrumental in extending the cultivation of the Science 

 in South Africa has increased the pleasure of what has on 

 my part been truly a labour of love.
