TERACOLUS sub-fasciatus, 

 Burchells Yelloiv. 



Family Papilionidse. Sub-family Coliana?. Genus ( ? ). Terocolus 



JVob. 



Generic Characters. 



Antennas with the club abrupt, and more or less compressed 

 anterior wings trigonal, posterior rounded; Palpi as in Colias, 

 but the scales intermixed with hairs. 



Specific Character. 



interior wings pale yellow, with a terminal orange spot, 

 margined externally with brown, and internally by a short 

 black bar ; areola with a black dot ; posterior wings yellow- 

 ish white, both beneath immaculate. 



Mr. Burchell was the first who discovered this unpublished 

 species in the interior of Southern Africa, and by his kind- 

 ness we are enabled to illustrate it. His specimens, 

 unfortunately, are not in the best condition, for he was 

 obliged to preserve many of his insects in books; and these, 

 having been among the number, may probably have had 

 the antenna; more compressed than they were in nature. 

 The form of this butterfly, nevertheless, is perfectly distinct 

 from Colias, as may be seen by comparing the nerves of 

 the anterior wings, here given in outline. 



Not having completed our analysis of the Colianse, we 

 cannot speak with any confidence on the rank or the 

 station of this type ; we are inclined to believe it is a genus 

 between those of Colias and Terias, connecting this sub- 

 family with the Licininee. It may, however, be one of the 

 sub-genera of Colias, in which case the genus, which it 

 would then represent, is unknown. Fig. I. represents 

 the anterior wing of Teracolus, 2, of Terias, and 3, of 

 Colias.
