In Dr. Laidlaw's recent account of this species ' he places 

 the BarkifrJa specimens under his " series A," which he believes 

 to be fairly typical examples of the true A. guttatus Burm. The 

 length of the abdomen varies from 55 to 58 mm. (Laidlaw gives 

 the length as 15 mm.) of the hindwing from 50 to 51 mm. The 

 venation is rather variable, but the antenodal nervures range only 

 from 15 to 17 and the postnodals from 7 to 9, the hypertrigones 

 being almost constantly traversed b} 7 3 nervures. 



With reference to the habits of this species Dr. Annandale 

 has a note in Laidlaw's account, and he also gives us the following 

 note on the colouration of a male specimen. " Head, including 

 eyes, sclerites of thorax, first abdominal segment, anterior trian- 

 gular area on dorsum of second abdominal segment bright leaf- 

 green with darker reflections on the eyes ; mouth parts yellowish- 

 green edged with black ; first abdominal segment and a triangular 

 area on the second also edged with black ; lateral region and 

 posterior part of dorsum of second abdominal segment bright 

 china-blue, also sides of dorsum of third segment; sides of latter 

 segment shining white ; these markings are most conspicuous in
