around the body, and the degree of striation in the dorsal scales, are 

 likewise other differences which can not be overlooked. 



"In coloration a vast difference is apparent at once. In sepsoides, 

 the ventral surface is immaculate yellowish, while in haetiana this 

 surface is black, spotted with irregularly shaped blue-white markings. 

 In sepsoides, the slight amounts of dark pigment appearing in the 

 dorsal scales are found in the central region of each scale, but in 

 haetiana all the dark pigment is concentrated at the lateral regions of 

 each scale, leaving the central portion conspicuously paler."
