I9I7-] P' ^'- LAIDI.AW : Indian Dragon/lies. 343 



Thorax metallic black as far as first lateral suture, sides and 

 under surface creamy- white with broad black lateral band along 

 second lateral suture. 



Abdomen brown, each of segments 2-9 with black apical ring, 

 and 3-7 with whitish apical ring (probably blue in the adult), 

 widening on the sides. Apical half of 8-9 whitish (or blue in the 

 adult) ; 10 entirely brown. 



Anal appendages. — Upper pair about equal in length to 

 segment 10, light brown, curved downwards, the distal half blade- 

 like, lyower pair white, slender, cylindrical, a little longer than 

 the upper pair, incurved at the extremity. Each carries a small 

 inwardly directed spur at its middle. 



$ Colouring as in male, but segments 8-10 of the abdomen 

 entirely brown 



Length of hind-wing 30 mm. Post-nodals 15-17 on forewing. 



I have examined an imperfect, immature male of this species 

 sent to me by Mr. H. Stevens. 



The species of the genera Drepanosticta and Protosticta will in 

 all probability turn out to be numerous and I am inclined to think 

 that the habitats will also prove quite restricted. Drepanosticta 

 quadrata (Selys) is recorded from the Malay Peninsula and Burma ; 

 I cannot feel sure that the Burma specimen is co-specific with the 

 Peninsular insect. 



Legion IV. Protoneura, Selys (restricted). 



Agrionid dragonflies, with a long and rectangular quadrilateral 

 without supplementary sectors. 



Ah normal, vestigial or absent ; never attached to the quadri- 

 lateral. 



Cm.^ represented only by Cw.^b, or absent. Cw, normal, reduced 

 or absent. Pterostigma rhomboidal. No supplementary basal 

 post-costal nerve. Wings not falcate. Size moderate, body slen- 

 der, or very slender. Legs with long cilia. 



Distribution : — 'Africa (excl. Madagascar ?), Tropical Asia, and 

 Australasia, Tropical America. 



I have but little acquaintance with American forms of the 

 Legion. I take their relationship to Old World forms as a matter 

 of course. 



The following table shows the grouping of regional genera 

 which I suggest, and indicates the characters on which I rely to 

 establish them : — 



A. Ac lies at a level about midway between the two costal antenodal nerves. 

 I. Ab normal (i.e. meeting the nerve descending from the distal end of 

 the quadrilateral (6'?^2b)- 



Hinder margin of prothora.x of female crenate or dentate. 

 a. Wings broad (length to breadth 4 : i). Cit^ reaching hinder mar- 

 gin of wing beyond half the wing length. Body rather stout. 

 Wings of males coloured. 



Chi.ohosf.vr.i, gen. nov. 



Type : C. quadrimaculata, Ramb. 

 Distribution : Central India.
