 black." 



( $ , no. 10.) " Apex of eye reddish brown, balance greyish 

 green. Epicranium, clypeus, and labrurn olivaceous. Dorsal 

 aspect of mesepisterna and notum olive-green. 



" Tergal aspect of abdomen rufo-flavescent, marked longi- 

 tudinally towards the outer edges of each tergite and near its 

 base with yellow. Median line and edges of tergites black. 

 Cercopoda tipped with black." 



Twelve specimens in all. 



Trithemis Tyleri, sp. n. (PI. XV. fig. 1.) 



(<^,no. 13.) u Apex of eye piceous, balance bluish grey. 

 Postclypeus olivaceous. Epicranium, anteclypeus, and 

 labrum dark olivaceous generally. 



" Dorsal aspect of mesepisterna, notum, and abdominal 

 tergites 1-3 dark infumated green, 4-10 fuscous, bordered 

 with black. Cercopoda olivaceous." 



Closely allied to T. umbrata, Linn. ; but in that species 

 the purplish-brown band lies between the nodus and the 

 stigma, whereas in T. Tyleri it extends from about the 

 triangle of the fore wings to halfway between the nodus and 

 the pterostigma, and the lower basal cell is slightly clouded 

 as far as the base. The hind wings are clouded from the 

 base to the outer level of the band of the fore wings, but the 

 basal part of the hind wings is paler than the rest of the 

 clouded portion, especially in the female. 



Described from three males and two females.
