90 bukmkister's odonata. 



Genitalia of 2 : lianuile aiul frenital lol)e equally proiiiiiient, anterior lamina 

 less so, its margin entire. Hamule bifid at apex, inner branch the more slender, 

 curved to form a hook directed backward, outer branch sliorter, obtuse, rounded 

 at tip. Genital lobe rather slender, about two and one-half times as long as wide, 

 curved slightl.v forward, narrowed at the tip. (PI. I, fig. 8). 



Wings clear, reticulation red, pterostigma dark brown, surmounting one and 

 parts of two other cells, membranule l>lackish. Arcuhis between first and second 

 antenodals, or at the second on hind wings of the unlabeled type, its sectors 

 stalked, separated throughout by one row of cells only. Nodal sector very 

 slightly waved, .separated from the subnodal by one row of cells except at the 

 wing margins. Sujjplenieutary sector next below the subnodal separated from it 

 (at the level of the middle postnodals) by two rows of cells, one submcdian cross- 

 vein nearer the base than is the first antenodal, no hypei'trigonals. 



Front wings with 15-13 antenodals, the last not continuous, 10-11 postnodals, 

 triangle with one cross- vein, internal triangle of three cells, three rows of post- 

 triangular cells to the wing margin (four cells immediately after the triangle on 

 the right, then three rows in the labeled type). Brownish yellow at base reach- 

 ing to the submedian cross-vein, or not quite so far (labeled type). 



Hind wings: 10-9 antenodals. 13-11 postnodals. triangle free, its pro.ximal side 

 in prolongation of the arculus, no internal triangle, two rows (three, then two 

 rows, left side of unlabeled type) of i)osttriangular cells increasing to 12-14 mar- 

 ginal cells, sectoi's of the triangle united (barely separated, left side of labeled 

 type) at their origin. Brownish yellow at the base reaching to the first antenodal 

 for the entire width of wing, but clearer in the median space (labeled type), to 

 the second antenodal w'ith the subcostal and submedian spaces darker brown 

 (unlabeled type). 



Total length 33-36 mm. Abdomen 23-24. Front wing 28-29. Hind wing 27. 

 Pterostigma 2.2.5. Superior appendages 1.5.

Two males in the M. C. Z. One has tlie pin-labels " Winthein" 

 (pr-inted), " Sanguinolenta * Br. Prom. bon. sp." (^written), the other 

 has tnerely the printed pin-label " Wiuthem" ; they are referred to 

 in the following description as the " labeled" and the " unlabeled" 

 types respectively. 



% (types). Almost entirely red ; labrum along its free edge, labium, bases of 

 the mandibles, occiput, rear of head and abdominal segments 13 inclining to 

 luteous. A very slight blackish streak on the middle of the latei'al carinte of 

 3 6 or 8 (middle of mid-dorsal carina of 3 5 and 8-9 very slightly browned; 

 trace of a small, median, apical, doi'sal, darker s])ot i>n 9 in the labeled type only), 

 sterna of 3-8 black. 



Hind lobe of prothorax narrower than the other lobes, its shajje that of a small 

 segment of a circle, its hind margin with a slight ujedian uolch.
