and usually yellow in the female ; the palpi are piceous ; the calyptra have the upper 

 scales nigrescent, and the under pale ; the hal teres are black ; the wings have the 

 front margins brown, and the fourth longitudinal vein bent in a curve. 

 This rare species was captured by Mr. Frisby, at Maidstone.

Nemoe^a quadraticounis, sp. n. 



Male : forehead prominent ; eyes clothed with long white hairs, rather widely 

 separated, the frontalia occupying about one-fifth of the head ; frontal stripe black, 

 rather wider than the sides, which, with the face, are glistening white ; fronto- 

 orbital bristles extending as low as base of second joint of antennae ; cheeks ciliated 

 with a few fine black hairs below the termination of the fronto-orbital setae ; antennae 

 black, second joint marked with white on its upper surface, third joint fully twice 

 as long as the second, widened and square-shaped at the extremity; arista short, 

 with second joint indistinct, and gradually thickened nearly to the end ; epistome 

 ■white and prominent, facial setae few and small ; thorax cinereous, the front and 

 sides being quite white ; it is marked by four black, rather narrow, lines, and has 

 three outer post-sutural dorso-central bristles ; scutellum yellow and translucent, 

 with the base grey j calyptra white j halteres yellow ; abdomen ovoid, with a rufous 

 patch upon the second segment, and the other rings tessellated with large brown and 

 white patches ; setae rather small, there are none on the first segment, but two upon 

 the disc, and two upon the margin of both the second and third ones ; anal segment 

 small ; ventral surface marked with black and white reflections, and having narrow 

 white margins to the segments ; wings with roots yellowish ; fourth longitudinal 

 vein bent at a sharp angle, where it is furnished with a rather long cubital appendix ; 

 apical cross vein nearly straight, and terminating rather near to the apex of the 

 wing ; outer cross vein oblique and sinuous ; legs black, hind tibiae irregularly armed 

 with setae on their outer sides. Length, 10 mm. 



This species bears close affinity with both the N. truncata and N. hreviseta of 

 Zetterstedt ; it differs from the former by having the second joint of the arista 

 short, instead of being elongated ; by the abdomen being tessellated with black and 

 white, instead of being fasciated with white, and by being of larger size. It differs 

 from the latter {breviseta) by having a cubital appendix to the wings, by the square- 

 shaped third joint of the antennae, and also by its larger size. 



This fine species was captured at Ipswich, and sent for my inspection in April, 

 1894, by the Eev. E. N. Bloomfield.
