tip, the following joint more thickened at the base, and tapering to the end, scarcely 

 compressed. In A. raptor (Wlk. Ins. Br. i. 221, 1), these two joints are much 

 more slender and compressed, the second a little gibhous at the base only, the 

 metatarsus still less thickened at the very extremity (fig. 8). In other respects the 

 two species are singularly like, except in colour, and differ equally from the third 

 species, A.ferox (Wlk. Ins. Br. i. 221, 2), see fig. 9. 

 Not uncommon on the wet rocks and tangle at Smerwick Bay (Kerry), in July.

Geomyza cingulata, pi. 2, fig. 10. 



Ferrugineanitida, thoracis vittis lateralibus abdominisque cingulis fuscis, articulo 

 tarsorum extreme apice nigro, alls immaculatis. 



Long 1, Exp. 2 lines. Pale ferruginous, shining ; a dusky band of the pleuraB 

 ending under the wing, and a fainter one above it, dusky ; the hind edge of the 

 abdominal segments in the male, the second segment entirely, dusky ; in the female 

 only the edge of the second and following segments dusky, and this interrupted in 

 the anterior ones. Face with two black bristles at each lower angle, a few very minute 

 ones along the cheeks. Antennae with the third joint rounded, arista hairy black. 

 The tip of the last tarsal joint and the claws black; fore femora with a black 

 spine beneath beyond the middle, besides a few slighter, scattered bristles. In the 

 male, the hind femora are ciliated beneath with very short black hairs. Wings 

 hyaline, rounded at the tip ; the costal vein yellowish, minutely and sparingly 

 pectinated, the rest light brown ; the prsebrachial veinlet before the middle of the 

 discal areolet. Halteres pale. 



On the silt of the Castlemaine river (Kerry), among the reeds, in July, not 

 rare.

Hal. Ann. Nat. Hist. iii. 411. Wlk. Ins. Brit. ii. 269. 



Cinereous, with pale pubescence, inclining to ferruginous on the mesonotum 

 and scutellum, elsewhere rather glaucous. Head broader than thorax, as long as 

 broad, above brassy-green, except the orbit and the stemmatic triangle, at each 

 side of which there is a small impression ; the ocelli very minute ; the orbit with 

 pale cilia. Eyes transversely oval, glabrous. Face, cheeks, and epistoma, glossy 

 whitish ; face short, convex in the middle, concave under the antennae, faintly 

 ciliated at the lower angles ; cheeks broad ; epistoma ample, vaulted. Antennae 

 short black, first joint very short, second transverse, third rounded, rather 

 broader than long ; arista finely pubescent, penultimate joint black, as long as 

 third of antenna, the last twice as long, slender, pale. Labium glaucous gray, palpi 

 and liplets rusty yellow. Wings whitish or obscure hyaline, veins brown, towards 

 the base yellowish, costal vein dusky ferruginous ; subapical and cubital both 

 straight, parallel ; discal veinlet straight, a little oblique, distant by little more than 

 its own length from the end of the pobrachial vein ; praebrachial veinlet a little 

 beyond the first third of the discal areolet; mediastinal vein distinct, rejoining the 

 subcostal at the end. Tibiae ferruginous at the base and tip ; trochanters some- 

 times tinged with the same colour ; tarsi rusty yellow, the last joint dusky ; ungues 

 curved, black ; onychia large, whitish ; empodium setaceous, pubescent, pale. 

 Abdomen somewhat conical, depressed, of seven segments, the second largest ; 

 hypopygium of male ending behind in two very short and stout black spines. 



A maritime species, not rare at Rossbegh creek; found also at Smerwick Bay ; 

 July to September.
