cells between Rs and Rspl, membrane large and prolonged nearly as far as the 
anal angle, base of hindwing in the male excavated slightly but nearly straight,’ 
anal triangle of 3 cells. 
Abdomen long and cylindrical, oreillets small, triangular, their posterior 
margin dentate ; 10th abdominal segment with a small, median, dorsal tubercle, 
only vestiges of lateral abdominal ridges on segments 4 to 7. 
Anal superior appendages long and lanceolate, the inferior subtriangular. 
Bor@er of 10th abdominal segment in the female subrotundate and subdenticulate 
beneath ; anal appendages in the same sex lanceolate and foliate. 
Only two species of this genus are known, of which the male of one is unknown. 
Anaciceschna jaspidea is the type of the genus and Anacieschna donaldi of 
which only the female hasso far been discovered differs from it only by the 
reticulation being more close and the nodal sector making only a slight but 
noticeable curve towards the stigma. Until the male is found, this species can 
only be placed provisionally in the genus. 
Anacieschna bears a close relationship to Anax, the shape of the base of the 
hindwing and the curve of the nodal sector beneath the stigma approach that of 
Anaz whilst the partial obliteration of the lateral, longitudinal ridges on segments 
4 to 8 bring it into near relationship with Hemianax. The presence of oreillets 
on the sides of segment 2 and the forking of Rs however connect it more closely 
with Aeschna. The genus must be regarded as the connecting link between two 
Jarge groups. 
Anacieschna donaldi, sp. nov. 
Female only known. Abdomen 53 mm. Hindwing 47 mm. 
1 female, Kodaikanal, 6,800’ May 1908, (teneral), 1 female from same locality, 
September 1921, and two others in October 1921, coll. T. B. Fletcher, 1 female, 
Yercaud, coll. T. N. Hearsey, September 1921, several females seen and taken, 
Ootacamund, September 1921. 
Head. Eyes dark olivaceous brown. the posterior border finely above, more 
broadly below apple green ; labium and labrum brown, face and frons olivaceous 
‘with shadings of blue ; above the frons greenish-yellow marked with a broad, 
dark brown “ T.” 
Prothorax dark brown coated with a faint, bluish bloom; posterior lobe 
simple, rounded and fringed with long hairs. 
Thorax rich maroon brown especially on the front of dorsum, marked with 
brilliant apple green as follows :—2 linear, transverse spots on the interalar 
sinus, a hook-shaped mark and a small spot on the tergum at the base of the 
forewings and 2 similar spots at the base of the hindwings. On the sides a 
moderately broad stripe between the two lateral sutures and an isolated, 
triangular spot at its upper end and a broad stripe occupying the posterior 
half or two thirds of the metepimeron. 
Legs entirely black. Posterior femora with a row of very closely set, very 
minute spines. 
Wings saffronated throughout, very deeply so in the teneral specimen from 
Kodaikanal. At the bases of both wings is a deep, diffuse smoky brown mark- 
ing not quite reaching the costa in front and limited posteriorly by the anal vein 
but extending into 3 cells of the anal triangle. Outwardly this mark extends to 
rather beyond the arc.
