rather long, and consisting of three cells. Hind wings 

 slightly tinged with deep yellow at the extreme base, fore 

 wings scarcely at all. Upper ulnar appendages slender, as 

 long as the last two segments, not much longer than the 

 lower appendage. 



Breves, Jan. 13, 1896. 



One specimen only. 



Diflfers from M. didyma, De Selys, and other allied species, 

 in the first row of post-triangular cells being formed of two 

 cells only, not three. 



I have named this species after Mr. Pickard-Cambridge, 

 who accompanied Mr. Austen in his journey. 



MicratJiyria eximia, sp. n. (PL XIII. fig. 3.) 

 Long. Corp. 22-26 millim. ; exp. al. 36-37 millim. ; long, 

 pter. 2 millim. 



Male. — Face pale yellow, inclining to greenish on the 

 sides ; antennal tubercle and centre of vertex metallic blue ; 

 mentum whitish, the medial line and the mandibles black. 

 Prothorax and front of pleura metallic green ; meso- and 

 metathorax and hinder half of the pleura pulverulent blue; a 

 broad pale yellow stripe, narrowed behind, on each side of 

 the thorax above, and three more, partly interrupted, pale 

 yellow stripes on each side, the uppermost narrow, slightly 

 angulated, the others more or less obliterated by the pulveru- 

 lescence ; tegulse pale yellow. Legs black, front femora 

 yellowish beneath towards the base. Abdomen black, 

 thickened towards the base and tip, with yellow lateral stripes 

 in front of segments 3-6 ; on segment 7 is a much larger 

 one on each side, separated by the dorsal carina; sometimes 

 there is also a lateral spot at the base of segment 8. Anal 

 appendages as long as the ninth segment, upper appendages 

 slightly curved downwards, of nearly equal thickness through- 

 out; lower appendage scarcely shorter than the others. Wings 

 clear hyaline ; fore wings with 7-8 antenodal cross-nervures, 

 the last not continuous, and 5-7 postnodals, the first two not 

 continuous ; triangle not traversed, followed by two rows of 

 cells, only increasing to three on the hind margin; subtrian- 

 gular space consisting of one cell only : hind wings with the 

 triangle not traversed and the sectors of the triangle separated 

 at the base. One cross-nervule in the lower basal cells ; no 

 supra-triangular nervules. 



Obydos, Feb. 2, 1896. 



Described from four specimens. 



A very pretty little species, not closely allied to any other. 

 A male from Para was previously in the Museum collection.
