This species^ the onlj^ representative of its genus, was for long 

 supposed to be confined to the southern slopes of the Himala3^an 

 range (see M'Lachlan, loc. cit.) Martin, however, has recorded it 

 from Tonkin and Ris from Formosa. 



The Museum collection contains 2 2 5 in spirit from Pashok, 



5,000 ft., Darjiling District, 14.vi.16, scarcely adult ( hy) ' ^^^ 

 one d' from Bhim Tal, Kumaon, 19—22. ix. 06 ( cj-) {N.A.). I have

The immature females have a large ^-ellow mark occupying the 

 middle of the dorsum of the prothorax ; and on the synthorax 

 there is a yellow stripe along each side of the mid-dorsal carina, 

 and another along the line of the first lateral suture : whilst from 

 the second lateral suture ventralwards the thorax is 3'ellowish 

 white. The dimensions of the female specimens are :

I have not seen an example of this rare and splendid Lestine. 

 I quote form M'Lachlan's account, '' wings for the greater part 

 "^ opaque blackish in the male, petiolated up to the first basal post- 

 '' costal nervule, which latter is placed nearer the level of the second 

 " than of the first antenodal nervule. Nodal sector commencing 

 " 8| cellules after the nodus in anterior wings {7-7I after in the 

 " posterior) ; ultra nodal sector commencing 3-4 cells after the 

 '* nodal. None of the sectors distincth^ broken (angulose) except- 

 '* ing the inferior of the triangle at its apex (the ultra nodal and 

 '* short sectors very slightly broken) ; one supplementary 

 '* sector (and rudiment of another) interposed between nodal 

 '* sector and median ; pterostignia very large, dilated, more than 

 '* four times as long as broad, surmounting 5-6 cellules. Ouadri- 

 '^ lateral broad, lower side twice the length of the inner, the outer 

 " angle somewhat acute. 

 *' Abdomen slender, spines of legs moderate. 



'' Head black above — prothorax olivaceous green. — Thorax above 

 " bronzy green, not metallic, somewhat paler (yellowish ?) on 



1 Species so mnrked are in the Indian Museum, Calcutta.
