On Hybrid Forms in the Genus Satyrium. 
293 
The following spiders and insects have been kindly determined by 
Dr. Peringuey : 
Thomisus sp. 
Synaema sp. 
Apis mellifica, var. caffra. 
Anisonyx ursus. 
Platychelus dimidiatus. 
In conclusion, it must be noted that fairly well advanced embryos were 
found in the ovaries of single specimens of each hybrid, but the significance 
of this in connection with what appears to be a distinctly intermediate 
morphological form between two good morphological species is, in the 
present state of our knowledge, of no deciding value. 
With the object of experimenting with the parent forms I have 
gathered individual plants with which I have initiated experiments in 
cross pollination.
