NEW AND LITTLE KNOWN HYMENOPTERA. 235 



Description : $ Head black, smooth, or but slightly punctured ; 

 the clypeus, the front between the antennas, the cheeks, and the 

 occiput clothed with rather coarse orange yellow pubescence ; the 

 antennas black cornute. Thorax black ; the prothorax, the mesothorax 

 anteriorly, the postscutellum and the metathorax above and on the 

 sides covered densely with the same orange yellow pubescence ; the 

 disc of the mesothorax and the scutellum naked closely and coarsely 

 punctured ; the metathorax posteriorly truncate, slightly concave, 

 smooth and shining ; wings sub-hyaline, of a light yellowish brown, 

 and brilliantly iridescent; a dark yellow stain spreads from the apex 

 of the medial, through the 1st cubital, into the base of the radial 

 cell ; legs black with hoary bristles and hairs, the anterior tibise 

 with three spines outwardly at their apex, their tarsi as well as 

 the tibiee and tarsi of the intermediate and posterior legs ciliated 

 with strong black spines ; the calcaria of the posterior pair of legs 

 transparent white. Abdomen black and shining, sparsely but coarsely 

 punctured, the segments 1 — 4 fringed posteriorly with hoary white 

 hairs ; this fringe is interrupted on the under surface of the 1st 

 segment, and in the middle on the dorsal surface of the 4th, the 

 pubescence here as well as that clothing the 5 th and apical segments 

 being black. 



This very fine variety of one of the commonest of the 8coliad<e 

 was kindly sent to me from Kumaon by Miss A. Brooke, and for 

 some time I was under the impression that I had got hold of a new 

 and undescribed species, as in a series of over a hundred specimens 

 of D. annulata, though there was considerable variation among the 

 individuals, none of the females wanted, as this specimen does, the 

 conspicuous dark tippings to the anterior wings. In other points, 

 however, this Kumaon specimen so closely resembles typical 

 D. annulata, that I cannot but consider it as an extreme variety of 

 that species, the more so as D. annulata is well known to be protean 

 in its variations.
