Black. Face yellow, with a black streak down the middle, tapering 

 upwards to a point, and a triangular black spot on each cheek, sometimes 

 connected with a streak proceeding from a large black spot which occu- 

 pies the portion of the yellow front immediately above the antennae ; 

 the vertex is ferruginous ; the occiput black, with a narrow yellowish 

 orbit. The proboscis, palpi, and antennae black ; the first joint of these 

 last ferruginous beneath. Thorax black, except the humeral scapulae, 

 which are usually yellowish ; the pleurae partially glossed with dull 

 golden tomentum, forming two oblique bands and a broader patch 

 behind them. Wings brown along the anterior margin, hyaline behind, 

 yellowish at the base, with the alulae and halteres. Abdomen black, 

 the hind margin of the second, third, and fourth segments glossed with 

 golden tomentum, forming three narrow yellow bands ; the two follow- 

 ing segments in the male are nearly covered with a duller yellowish 

 tomentum ; and in both sexes the sides of the abdomen are often 

 spotted with brown. In the female the fifth ventral segment is not 

 nearly so prominent as usual, merely forming a semicircular fold with 

 a depression behind it. The coxae are black, the trochanters and tibia 

 ferruginous, as also the base of the tarsi, and the base and tip of the 

 femora ; the last more largely on the under side, and the proportion of 

 black in the femora varies. 



A single specimen (male) was found by Alfred Eurlong, Esq., 

 near Killarney, in the summer of 1850. (I.) 



Individual description of this specimen in full : 



"Black, First joint of antennae ferruginous beneath. Facial orbit 

 yellow, a deep black dot above at its commencement, distinguished 

 from the duller black ground-colour. A bifid yellow band down the 

 face, the arms of which diverge from the base of the antennae and are 

 continued to the peristoma. Occipital orbit narrower, yellow with a 

 silvery gloss, produced downwards to the peristoma, and there meeting 

 the facial band, and also connected along the eyes with the facial orbit. 

 Obs. The black band (rugose in its upper part) which divides the facial 

 yellow band from the anterior orbit is greatly attenuated and almost 

 interrupted in the middle (if this interruption were complete, there 

 would be a triangular black spot on the cheeks, as described by Loew). 

 Peristoma internally yellow. Thorax black ; the prothoracic tubercles 

 fusco-ferruginous. The pleurae with markings of dull golden tomen- 

 tum. Halteres yellow. Wings dusky along the entire costal margin, 

 hyaline behind, but at the base yellow, as are the alulae. Coxae black, 

 with the apex ferruginous. Tibiae yellow-ferruginous, the hind pair a 

 little dusky at the internal apex. Tarsi black-brown, the base and the 

 onychia ferruginous." Haliday, MSS.
