70 DIURNAL LEPIDOPTERA. 



said nervure. Thus curtailed, the genus Thecla will contain a large number of species 

 of great diversity of form and colour. The species with which I have commenced the 

 genus, amongst them some of the most glorious things in creation, have the anal 

 angle slit into two parts, the terminal joint of the palpi of the males very short, of the 

 females very long. I may not have placed this genus in the best position with regard 

 to the neighbouring genera, but I have been anxious to commence it, having had by 

 me for a long time all the new species from the collections of Mr. Bates and of Mr. W. 

 W. Saunders, whose kindness, together with the stores of the British Museum, will 

 enable me to figure in my next Part upwards of one hundred new species.

 Guatemala. 



The male of this gorgeous species, which surpasses the imperialis and regalis, is born with- 

 a crown upon its head, the male having between its eyes a remarkable conical projection, highly 

 gilded in front. Its palpi are longer than those of T. regalis.
