vein, the patch being slightly larger than in C p. plagiata Jord. (1012) and a little 

 more distal iu position. The white patch of the hindwing, which e.Ktends oblinnely 

 towards the outer margin above the anal angle in C. p. plagiata, is truncate 

 pro.ximall)' and rounded or snbtrnncate distally in G. p. satisbona ; the black 

 abdominal border of the hindwing is narrower than in C. p. plagiata, being 

 anteriorly bounded by SM", the outer border having the same width at the anal 

 angle as the abdominal border. 



On the underside, the white patch of the hindwing is much larger than above 

 in G. p. jilaqiata, and e.xtends anteriorly to the base, whereas in G. p. satisbona the 

 patch has practically the same size as above, the base of the wing remaining black. 

 The black border of the hindwing beneath is shaded with metallic blue in satisbona. 



AN INTERESTING FORM OF PLANEMA MACARIA. 



By Dr. K. JORDAN. 



Planema macaria hemileuca subsp. nov. 



S. Ala postica fascia mediaua alba oruata. 



Long. al. ant. 34 mm. 



In colouring very similar to Planema macarista E. M. Sharpe (1906). Fore- 

 wing in the apex of the cell with a small orange spot, which is joined to the 

 discal band. This band very sharply defined and broader than in macaria F. (1793) 

 and macarioides Anriv. (1893), being 9 mm. wide at the median veins, its distance 

 from the outer margin being 4 mm. and 2 mm. respectively at these veins. The 

 inner edge of the baud is more oblique than in macarista, the band being narrower 



at the inner-marginal vein than in macarista. The band of the hindwing is pure 



white, as sharply defined proximally as in macarista, and distally rather more so 

 than in that species ; it just enters the lower angle of the cell, and has a width 

 of about 4 mm. at the subcostal vein and of ,S at the lower median branch, the 

 brownish black distal border being of even width (apart from the rays) from the 

 costal margin to the lower median vein. 



On the underside the band of the forewing is whitish at the posterior extremity 

 and shaded with white in front of the inner-marginal vein ; its proximal edge is 

 concave between the median veins and forms an oblique double sinus between the 

 lower median vein and the submedian one. 



The genitalia are the same as in P. macaria and macarioides, being quite 

 different in P. macarista. The most characteristic feature, and very easily visible 

 on removal of the eighth tergite (last outer), is the anal tergite, which, in the 

 forms of P. macaria, is divided into two broad, short, dentate lobes which are 

 directed obliquely sidewards, the sinus between them being wide and rounded.
