3. melanoceras, n. "Nigra, antemiis toils nif/ris, alls obscure 

 hyalinis, vexa suLcosiaU in costali exeimte contra areolam, furca vence 

 pobracJtiaUs ante medium aire. Long. 1-i ; alar. 3 lin." 



" Black, slightly shining. Month and palpi yellowish. AntenncB 

 wliolli/ hlacJi-, filiform, longer than the thorax. Thorax slightly glisten- 

 ing-cinereous, with some yellowish hairs. Wings obscurely hyaline ; 

 veins brown ; the three anterior or costal veins stouter, blackish-brown 

 except at the base ; subcostal vein complete, ending in the costa very little 

 beyond the base of the areolet, which is elongated as in T. Jilrta, but 

 slightly dilated at the tip ; median vein not longer than the areolet, 

 and for the most part pale ; fork of the pohrachial vein opposite the 

 base of the median vein, and therefore longer than the fork of the prce- 

 hrachlal, but not so near to the base of the wing as In T. hirta. Halteres 

 whitish. Abdomen elongated, with pale sutures. Legs yellow ; tips 

 of the coxfij of the hind femora and (more slightly) of the hind tibite 

 brownish ; tibise darker than the femora, with pale yellow spurs ; fore 

 tibiae bare, the posterior minutely spinulose ; tarsi almost brown ; fore 

 tarsi not twice the length of the fore tibite, dilated, and slightly com- 

 pressed in the middle." — Hal. MSS. 



Very rare. Has been found at Holywood^ near Belfast. In 

 Mr. Ilaliday's collection. (I.) 



" The subcostal vein running to the costal^ and the length of the 

 fork of the pobrachial^ seem to afford the chief distinctive cha- 

 racter of this species. I should remark that the subcostal vein 

 running to the costal takes away one of the distinctive characters 

 of Telragoneura, as compared with Scwphlla ; but the near ap- 

 proach of tlie radial to the cubital, and consequent narrowness of 

 the small areolet^ and the cubital vein terminating some way before 

 the tip of the wing, with the general resemblance to the other 

 species of Tetragoneura, led me to place it in this genus." — Hal. 

 MSS.
