Male. Grass-green. Head and prothorax on each side with a whitish 

 brown-bordered line which extends from the eye to the base of the fore 

 wing. Head elongate; tip of the vertex concave, nearly triangular, the 

 furrow on each side linear; front oblique, with four distinct keels 

 which diverge towards the face, the inner pair connected at their 

 junction with the tip of the vertex. Prothorax with three very slight 

 keels ; lateral keels occupied by the two lines, parallel from the fore border 

 to the first transverse furrow, very slightly diverging from thence to the 

 hind border, which is rounded. Abdomen testaceous, a little shorter than 

 the hind femora. Hind femora with a brown stripe beneath. Hind tibiae 

 with a paler band near the base. Fore wings nearly pellucid, with a grass- 

 green lanceolate stripe on the costa and another on the hind border; a row 

 of pale brown dots between the stripes and three very irregular rows of very 

 pale brown dots in the exterior part. Hind wings slightly cinereous, 

 brownish about the apical part of the exterior border; a brown streak along 

 the exterior part of the costa ; veins black, testaceous at the base and along 

 the interior border. Length of the body 9 lines; expansion of the fore 

 wings 16 lines. 



The structure of the tip of the vertex will distinguish it from S. via- 

 torius, and the slight transverse furrows of the prothorax will distinguish it 

 from S. tepanecus. The lateral keels 011 the prothorax of S. mystecus are 

 parallel.
