I9I9-] F- F- Laidlaw : Indian Dragonfiies. 179 



The general agreement is, however, so close that I have little 

 hesitation in referring them to the Selysian species. 



Like the species described next below, A. ladeola has the upper 

 anal appendages, which are each provided with a strongly developed 

 ventral spur, directed downwards, and having an acute apex. 



The ground colour of the body and abdomen is bluish-white, 

 there is no differentiation of the ground colour of the terminal 

 segments of the abdomen such as characterizes A . pier is. 



The specimens are identical specifically with those taken on the 

 Abor Expedition. The type of A ladeola, Selys, is from Ben:ial. 

 I have no doubt but that the present specimens are conspecific. 

 with Selys' type.

Eyes. — Upper third black ; lower two-thirds white. Antennae, 

 basal joint pale blue; the rest black. 



Prothorax, anterior lobe white, middle and posterior lobes 

 black ; a small white spot on either side of the middle lobe in one 

 specimen ; the posterior lobe with a median, rectangular, slightly 

 bifid projection, much as in A. ladeola. Selys, edged with white. 

 Under surface white. 



Thorax, dorsum velvety black as far as first lateral suture, 

 with narrow pale yellow antehumeral bands; sides and under 

 surfaces white, with a fine black line at the upper end of the 

 second lateral suture. 



Abdomen. — Segments r-7 white, marked with black as fol- 

 lows : — 



(i) With mark covering the whole dorsum of the segment. 

 (2) With longitudinal black band expanding basally and 

 apically to form terminal black rings, and widened 

 in rectangular fashion just behind the middle of the 

 segment. 

 {3-6) With black basal and apical rings, and with an ar- 

 row-like longitudinal mark, the head of the arrow 

 directed forwards. On segment 5 the "shaft" of 

 the arrow is much reduced.
