CONCLUDING REMARKS. 351 



student of Natural Science is keenly alive to the value of aid 

 such as this, for he knows that, isolated, he can accomplish 

 little indeed. 



To James Henry Bowker, Esq., Inspector of the Frontier 

 Armed and Mounted Police, I am indebted for all the know- 

 ledge I possess regarding the Lepidoptera which inhabit 

 Kaffraria Proper, that productive Coast region which extends 

 from the Rr/er Kei to the Southern Frontier of Natal. Mr. 

 Bowker's services to Botany are well-known, and his con- 

 tributions to Entomology during the past four years have 

 been no less important. In that period, he has collected, 

 and transmitted to the South African Museum, several 

 thousands of entomological specimens, mostly very well pre- 

 served, and has been in constant correspondence with me 

 regarding them. His labours have been rewarded by the 

 discovery of several species new to Science, and by the cap- 

 ture in abundance of many previously very rare in collections. 

 But I need not further descant on services which are best 

 borne witness to by this work itself, in the Second Part of 

 whnh Mr. Bowker's name, usually accompanied by his inte- 

 resting notes, occurs upon every other page. 



Mrs. Barber, of Highlands, near Graham's Town, has 

 supplied me with many species taken in her neighbourhood, 

 together with graphic observations on their habits and earlier 

 stages of being. This lady is an accomplished botanist, and, 

 like her brother, Mr. Bowker, is gifted with observant 

 powers of the highest order. 



Another phytologist, M. J. McKen, Esq., Superintendent 

 of the Botanic Gardens at Port Natal, has, during the past 

 year, most assiduously cultivated entomology, supplying the 

 South African Museum and my own collection w'ith fine 

 series of Natal insects, including many essentially tropical 

 forms which do not appear to extend further to the South, 

 and several species which I believe to be undescribed. Mr! 

 McKen is now engaged on the observation and description 

 of Lepidopterous larvse and pupse, a study that will assuredly 

 throw much light upon our knowledge of the African species. 

 John A, Bell, Esq., of H. M. Customs, Port Elizabeth, 

 upon his return from a journey through Damara Land to 

 Lake Ngami, most liberally presented me with all the Lepi- 

 doptera (chiefly Butterflies) that he had collected in those 

 little- explored regions. Mr. Bell, despite his lack of all 

 entomological apparatus, collected specimens throughout the
