nearly evenly forked and with a small ventral tooth ; inferior appendages

4. Diplacodes parvula, Rambur, 1842. 



This insect is very closely related to Z>. nelmlosa, differing from it by 

 possessing a blackish basal spot to the hindwing and by not possessing 

 apical markings. It almost entirely replaces D. tricialis in Mesopotamia 

 and in part at least, in N. W. India. The insect is fairly common in 

 Karachi.

2 S 6, and 2 $ $ . Shillong, September 1918. T. Bainbrigge Fletcher. 



Length of hindwing 23 mm. Length of abdomen 31 mm. 



Male : Head, eyes reddish brown above, paler beneath, an equatorial 

 brown line separating the two coloured areas, labrum rust red, with a row of 

 small black spots along its border, rest of head black marked with a 

 broadish rust red band crossing between the anterior part of the eyes and 

 two obscure spots on the outer side of the lateral ocelli. 



Prothorax black marked with longitudinal, red, subdorsal stripes and 

 with a minute dorsal, geminate spot on the mid-lobe and a single, tiny 

 spot on the dorsum of the posterior lobe. Lateral border of middle lobe, 

 narrowly red and two minute red spots on the posterior border of the 

 posterior lobe. 



Thorax rust red on the dorsum, fading to a pale fleshy tint laterally. 

 Marked very irregularly and variably with black as follows : — a broad, 

 middorsal band, another broad, subdorsal band, incomplete above and 

 behind where the ground colour invades it irregularly. A line on the 2nd 

 lateral suture, split more or less longitudinally and irregularly and an 

 elongate spot on the metepimeron. Tergum mottled with rust red. 



Abdomen black marked with red or wedgewood blue. The apical border 

 of the first segment red ; a longitudinal, fine red line on the dorsum of the 

 second segment ; 2 subdorsal lunules on the apical borders of segments 3 to 

 7. Obscure reddish or bluish spots on the sides of segments 3 to 6. The 

 sides of the first and second segments red or purplish. 



In some specimens the ground colour or markings are entirely wedge- 

 wood blue but they do not appear to be more adult than the red-marked 

 ones, in which, especially on the head, the red is of a very intense 

 character. 



Legs black, base of femora and extensor surfaces of tibioe rust red. 



Anal appendages of the usual disparoneurine shape, the superior with 

 pointed apices and a robust ventral spine and the inferior sloping and 

 tapering ventrally and rather longer than the superior. 



Wings distinctly tinted, especially along the costa and apices ; stigma 

 crimson, the hinder border paler. 



Female similar to the male, the markings being rather more defined and 

 very irregular,
