dorsal edge ; tarsus 2, 1, 1, 1,3; the first joint bears one dorsal subapical bristle, one 

 anterior, one ventral, and three (stouter) posteriorly ; joints 2-5 have bristles 1, 1, 2, 1, 

 while five bears 1, 1, 0, 1. Mid coxa much widened posteriorly; femur (10:3) 

 shorter (6 : 7) than tibia (barely 6:1), which has about eight short stiff bristles along 

 the dorsal edge and four ventrally on apical third. Tarsus as long as tibia, each 

 joint with one subapical bristle dorsally and another apically and ventrally ; joints 

 in ratio, 8, 7:7:5:9. Hind coxa (7 : 4) with 5-7 short heavy spinose bristles ; 

 femur (2:1) one-seventh longer than the coxa ; tibia (3:1) three-fourths of the coxa 

 in length ; tarsal joints in ratio 15:9:7:6: 11. 



Abdomen. The tergites from the second (fourth) onwards are deeply incised 

 postero-medianly up to about one-half of their length. Between the spiracles is a 

 broadish membranous area, and this tergite is produced anteriorly into a broad, 

 angularly rounded median lobe. The stylet (8 : 5) bears four bristles — three apically 

 and one at the side. The ovipositor sheath is slightly dilated apically, the ovipositor 

 extending beyond the apex of the abdomen a distance of about 0-6 mm. The spiracle 

 (fig. 3, e, e^, same scale as d) is oval, flattened on one side. 



Length (excluding ovipositor) 1 -4 mm. ; alar expanse, 2-4 mm.

E. verticillata, sp. n., is an isolated form which I have placed in this genus with 

 some reluctance. It is easily recognised by its antennae, wings, protergum, etc. The 

 material available for description is in a very broken condition, there being only two 

 complete antennae and one wing in a score of specimens. Such dealation and loss 

 of appendages are commonly incurred when the female enters the fig in which the 

 eggs are to be laid. 



The neuration of the single wing preserved is peculiar and perhaps abnormal. 

 There is a distinct marginal and postmarginal length, and in the membrane itself a 

 disconnected pellucid thickening, suggesting an obsolescent radius. Particular atten- 

 tion is for this reason directed to fig. 3, c, which illustrates the points referred to.
