Anal appendages. — Upper pair pale blue, as long as segment 

 10, somewhat finger-shaped a little incurved. Each carries a 

 downwardl}^ directed projection, not visible when seen in profile 

 in the natural position. The projection ends in a sharp point. 

 IvOwer pair minute, conical, not visible in profile. 



Legs white, posterior surfaces of femora with longitudinal 

 black bands. 



Pternstigmata, fore- wings gray white, hinder wings darker. 

 Fost-nodal costal cross veins 5 or 6. 



Female 



Head, prothorax and thorax much as in the male, but the 

 ground colour is distinctlj^ greenish- white. 



Abdomen pale blue, with a broad longitudinal black band 

 on the dorsum of each segment, widening a little before the apex 

 of the segment, then narrowing again to meet a black apical 

 ring on each of segments 3-7. Segments 8-10 black above. The 

 blue of the abdomen is of a deeper shade than in the male. 



Legs as in the male but the black on the femora is darker. 



Anal appendages blue. 



The males show a certain amount of variation in the extent of 

 the black markings on segments 6 and 7 of the abdomen. They 

 are readily distinguished from the males of the species I have 

 identified as lacteola, Selys, by the white abdomen tipped with pale 

 blue on segments 8 and 10, and by the extensive black marks 

 on the legs. 



Ris has lately described a species A. selenion from Formosa. 

 Unfortunately his account published in Berlin {Supplementa Ento- 

 niologica, Berlin, No. 5) is not available to me. I have been 

 able to see a copy in the Natural History Museum for a short time. 

 To judge from the figure of the anal appendages it must be allied to 

 A . lacteola. 



lyastly, A. nana. I,aidlaw, from the Kachin Hills has again very 

 similar appendages although the colouring is different and segments 

 8 and 10 are black. 



It should be noted that the upper anal appendages of this 

 group are extremely like those found in the genus Argiocnemis. 

 A. lacteola may be taken as the type of a group within the genus 

 which includes A. pier is, and perhaps A. nana and A. selenion 

 as well. This group may ultimately prove worth generic sepa- 

 ration from such species as A. pygmaea and A. incisa. 



A . pieris seems to be a western species and A . lacteola an 

 eastern, so far as India is concerned.
