1 ate. 
Wings. Forewings, length 3-7 mm., breadth 1-3 mm. The ratio of 
submarginal : marginal : radius : postmarginal is approximately 10 : 3 : 
1 : 1 the ratio between postmarginal and radius more accurately 14 : 17 
while the marginal is about 2| times the radius. The radius is distinctly 
longer, not so sessile, more pedunculate than in ruficaudis. In the 
subcostal cell the bristles are much more numerous than in ruficaudis. 
At the costa, they stand (minute) 2-3 deep along the entire length, and 
(also on the underside) there are numerous longer bristles on the apical 
third of the cell. The bristles of the basal half of the cell are tinted and 
stronger than in ruficaudis. On the disc the bristles are denser and 
longer, no bare track between apex of radius and base of the marginal. 
The first isosclinal row from the apex of the radius, ill-developed and 
not isolated, is made noticeable mainly because of the darker tint of the 
membrane along its course. The second is less distinct than in ruficaudis. 
Hindwings slightly narrower, length 2-5 mm., breadth -67 mm. 8 small 
bristles at the hooks. 
Hind legs. Tibial comb ; 12 spines across the apex behind, and 8-9 
dorsally along the posterior edge of the apical cleft. The spur is nearly 
smooth and very short — only |th longer than the spines of the comb and 
about \ the length from its own base to the ventral apical angle of the 
tibia. 
Abdomen, smooth, and shining except where the surface is broken by 
the insertion of the hairs. The long base of the ovipositor (the 7th visible 
tergite) shews numerous large setigerous punctures on its basal third. 
After the process the surface is dull and reticulated. The apex of this 
segment lies at about whereas in ruficaudis it extends nearly to the end 
of the ovipositor {cf. figs. 7, a and 6, a) length, 8-9 mm. (of which the 
ovipositor is 3-3 '4 mm.) alar expanse about 8-9 mm. 
Type $ in British Museum one of a series of three. Bred out of 
Heritiera Forties Buch., attacked by Chrysobothris (Buprestidae) 
Glenea (Lamiidse), Ozotomerus maculosus Perr. (Anthribidae) probably 
parasitic on the Buprestid. Pupates in the bark in the pupal chamber 
of the boring larva.
