NOTHOLESTES ElWESI, «. Sp. 



$ . Abdomen, 36 mm. Iiiferior-wing, 31 mm. 



Wings narrow, but gradually dilated to the rounded apex, the inferior broader 

 than the superior ; hyaline, but slightly tinged throughout with olivaceous ; 14 — 16 

 ante-cubital nervules, 23—25 post-cubital ; pterostigma (2 mm.) brownish-black, 

 surmounting 2^ cellules. Head, above, brassy-cupreous, black behind the eyes ; 

 rhinarium metallic-green ; labrum metallic-cupreous, with a yellow spot on each 

 side ; second joint of antennae yellow, the rest black ; labium, &c., black. Thorax 

 brilliant metallic-green, with a brassy tinge, the sutures blackish ; sides (below the 

 inter-alar pleurae) and breast pale yellow, with an isolated bronzy streak on the 

 metathoracic pleurae ; the space between the legs black. 



Legs black, but the coxse and trochanters are pale yellow, like the breast. 



Abdomen bronzj-cupreous, becoming blackish after the 5th segment, and 

 blackish beneath ; 1st segment yellow at the sides and beneath ; 9th segment above 

 powdery-white (and there are indications that this white pulverulence may extend 

 to the 8th) ; 10th segment nearly as long as the 9th, its margin regular, slightly 

 rounded. Supei'ior appendages scarcely longer than the 10th segment (owing to 

 their form), black, forcipate, strongly geniculate in the middle; they are thinnest, 

 at the point of geniculation ; the apical portion dilated, obtuse, sinuate and 

 excised on the inner margin before the apex ; externally are three sharp teeth on 

 the basal half of the apical portion (beyond the geniculation). Inferior appendages 

 black, shorter than the superior, flattened, nearly straight and sub-parallel ; but the 

 apices are thickened and inturned, and there is an internal tooth below the apex, so 

 that the tips appear bifid internally with an excision between the two teeth. 



? unknown. 



Hab. : Darjiling ; one $ given to me by H. J. Elwes^Esq., E.L.S., 

 by whom it was captured. 



In general form, metallic coloration of the body, the white- 

 powdered 9th segment, and also in the appendages, this insect has so 

 much resemblance to a somewhat large Lestes, that I had so considered 

 it, until the neuration revealed its true position.

NOTES ON NOMAD A. 

 BY EDWARD SAUNDERS, F.L.S. 



Mr. R. C. L. Perkins' remarks (vol. xxiii, p. 273) on those species 

 of this genus which are inquiline on Salictus open a very interesting 

 question. The females of Salictus, as he points out, hibernate, but 

 this habit has not been observed in Nomada, and if it does not exist 

 in that genus the question arises, how is the race of the inquiline 

 continued ?
