ferruginous colour will distinguish it from all other species except 

 crishna Wlk., which latter is easily separated by its leaden black 

 abdomen. The coloration of the posterior femora is variable, the 

 difference between the pale yellow basal half and bright tawn^^ 

 red apical half being sometimes very striking, whilst in some speci- 

 mens the colour is almost uniformly tawny. In its yellow face 

 it is allied to Walker's first species named costalis (from the Aru 

 Islands), but costalis has four black spots on its face and four 

 black lines on its thorax, whereas ferniginosus has only two black 

 spots (which are on the frons) and only two narrow black thoracic 

 lines, close together, which sometimes form one broad band by the 

 intervening space being darkened. 



S. crishna Wlk., 1861. 



Proc. Linn. Soc. Lond., v, 291. 



The only specimen that I have seen (a 2 in the Indian Museum 

 collection), and that I can identify with this species was captured by 

 Dr. Annandale's collector at Matiana (8,000 feet), Simla hills, on 

 28th to 30th April, 1907. It agrees in every particular with 

 Walker's description, except that he says the dorsum of the thorax 

 is black, whereas in the present specimen it is uniforml}' light 

 ferruginous with the rest of the body. I think Walker's specimen 

 may have been discoloured, and that my identification is correct. 



Two other species were described by Wiedemann, senex and 

 imhutus ; they are from unknown localities, and are in the Vienna 

 Museum. I mention them because the author's other three species 

 all occur in the East. 



S. senex Wied. is grey haired, with blackish brown antennae, 

 the 3rd joint being whitish at the base ; the face is yellow, frons 

 reddish yellow with two brown streaks, thorax with two blackish 

 lines on dorsum, and a white shimmer on the sides and front ; 

 abdomen brown, or in certain lights, blue ; wings deep yellow 

 with brown tips ; legs reddish yellow, posterior pair rather reddish 

 with pale base ; the fore pair and the tibiae black, cf long. <^^ mm. 



The deep yellow coloured wings mentioned by the author 

 readily distinguish this species. Locality ? 



5. imbutus Wied. is dull leaden, differing from senex in the 

 reddish yellow base of the 3rd antennal joint ; frons and face 

 pearl bluish ; wings very lightly yellow, tips distinctly brownish, 

 the darker colour extending to and enclosing the middle cross 

 vein. Minor differences as regards the colour of the legs are men- 

 tioned, (f long. 5 mm. Locality ? 



Either of these species ma^^ be found in the Oriental Region.
