716 MR. R. E. TURNER ON 



of E. dimidiata Guei\, from wliicli the female differs in the 

 entirely black abdomen and the greater length of the second 

 abscissa of the i-adius, which is nearly as long as the third. The 

 male differs from dimidiata in having the second abscissa of the 

 radius very distinctly longer than the third, in the paler colour 

 of the ajjical portion of the wings, in the presence of a distinct 

 longitudinal sulcus on the median segment, and in the somewhat 

 shorter and broader form of the first abdominal segment. The 

 pygidial area of the male is also wider and less distinctly margined 

 than in dimidiata.

The four basal abdominal segments are ferruginous ; the wings 

 violaceous, the base of the hind wings hj^aline. Pronotum 

 spaivsely but coarsely punctured. 



Length 15 mm. 



This is quite distinct from dimidiata, and seems, as Camei'on 

 suggests, to be more nearly related to mandalensis.

$ . The live basal abdominal segments are ferruginous. 

 Calcaria and spines of the bind tibite whitish. Wings hyaline, 

 dark fusco-hyaline beyond the basal nervure of the fore wing- 

 to the apex, the apex of the hind wing fusco-hyaline. Pronotum 

 closely and somewhat coarsely punctured ; sixth dorsal segment 

 liuely longitudinally striated. 



J . Head and thorax closely and rather finely punctured ; 

 median segment punctured-rugose ; abdomen shining, micro- 

 scopically punctured. First abdominal segment scarcely longer 

 than the hind femiu' and trochanter combined, the narrow petiole 

 a little more than half as long as the moderately swollen apical 

 portion of the segment ; second segment longer than the third 

 by about one-quarter. Seventh dorsal segment pointed, not 

 incised ; pygidial ai-ea well defined, very narrow, coarsely 

 punctured and with a well-marked median carina. Third 

 abscissa of the radius distinctly longer than the second. 



Black ; mandibles at the base, clj^peus, apex of the inter- 

 antennal prominence, posterior margin of the pronotum, tegulfe, 

 an apical band on dorsal segments 1-6, strongly bisinuate on 

 segments 2-6 and on ventral segments 2-6, tarsi, fore and 

 intermediate tibia; in front, and the base of the hind tibiaj yellow. 

 Wings hyaline, nervures fuscous.
