Group BRACHYTROX. 



Series Boyeria. 



The genera of this series are characterized by the abseuse of 

 a fork to Rs, and by the single row of cells between Rs and RspL, 

 and between M^ and Mspl. respectively. These genera are but 

 few in number, and are generally regarded as primitive. The 

 oriental genus Jagoria shows some specialization in respect of the 

 large eyes and of the dentigerous plate of the female. 



Jagoria martini, n. sp. 



I 5 . Near pool, Tiger hill, 8,300 ft , Darjiling Distr., 26-vi- 

 1918 {S. II'. Kemp). 1407-2. The specimen is the type. 

 Length of hinder-wing 40 mm, of abdomen 40 mm. 

 Venaiion. That characteristic of the genus. Nodal indicator 



8 — Q~ Ti — it ■ 1 riangles of fore-wings of three cells, of hinder-wings 



four celled. Supra-triangles free. Space between M^ and Mspl. 

 of two rows of cells on all wings. Pterostigma dark brown, 2 mm. 

 long, braced. Extreme base of wings saffron tinged, the colour 

 not reaching Ax^. 



Head. — Lower lip, and all the anterior surface orange brown. 

 Dorsal surface of frons very dark brown, black against the eyes : 

 enclosing a yellow mark on either side in front of each eye, so 

 that the dark colour forms a T-shaped median mark. Verte.K and 

 occiput black, the latter minute, with a tuft of black hairs. 



Prothorax. — Dark brown. 



Synthorax. — Dorsal surface very daik brown, with a pair of 

 oblong oval bands of a blue green colour, running upwards and 

 inwards almost to the upper end of the mid-dorsal carina, but 

 not reaching it ; a pair of small lines of the same colour start from 

 near the upper end of the first pair and run transversely towards, 

 but not so far as the humeral suture ; meso- and meta-notum green. 



Laterally the synthorax is very dark brown with a large, 

 vivid green bar on the mesoepimerite and a second bar of the 

 same colour nearly covering the whole of the metepimerite. 



Undersurfaces orange brown. 



i-l&rfowie« constricted sharph' at the third segment, widened 

 again from the fourth to the sixth, the remaining four being narrow ; 

 colouring, black above, the sternites orange brown. Segment i 

 has a large, green, lateral mark, similar to those of the sides of the 

 synthorax, but slightly more yellow in tone ; 2 has a lateral yellow- 

 band. Dorsally segments 2-6 have each a pair of apical green 

 spots, semilunar m shape, and very small on 6. In addition 2-4 

 have each a pair of small transverse marks of a green colour at 

 about the centre of each. Further, 2 has a minute basal triangle 

 of yellowish green. 



The legs are black ; the coxae, trochanteres and bases of the 

 femora brown.
