the 2d segment a large black plate, occupying the whole segment, 

 except a small portion at the edges and apex ; on the 3d segment 

 there is across the centre a large black band, and on the 4th there 

 is a small band, somewhat spindle-shaped. On the back the 2d 

 segment is black, with the exception of the edges; sometimes 

 the black portion is divided down the centre by a faint white 

 line. Length about 4 lines. 



It blotches the leaves of the oak in the autumn. The larvae 

 (for which I am indebted to their discoverer, Mr C. Healy), 

 with me cast off their skins so compact, that they retained the 

 shape and all the markings which were on them when enclosing 

 the larvae. 



Gi-ijpocentrus incisulus, Ruthe, is a parasite on an oak-leaf-mining 

 Phaenusa, ^voh^ihly ijygmoMi {cf. Brischke, I.e., 89). 



5. Phaenusa albipes. 



Phaenusa albipes, Cameron, Ent. M. M., xii., 131 (1875). 



Black, shining, covered sparsely with a very short pile, only 

 visible in certain lights. Antennae a little shorter than the body, 

 slightly pilose; the 3d joint longer than the 4th. Feet entirely 

 white ; posterior tarsi and tips of anterior faintly fuscous. Wings 

 smoky ; costa, nervures, and stigma black ; marginal nervure 

 received a little past the middle of the 2d sub-marginal cellule. 

 Sheaths of saw and saw itself largely exserted. Length scarcely 

 IJ lines. 



Easily known by the almost entirely white legs. 



One specimen taken in Gadder Wilderness, near Glasgow, on 

 20th August, 1875. The larva is unknown. 



6. Phaenusa pumilio. 



Fenusa immilio, Hartig, I.e., 259, 5; Thomson, I.e., 187, 5. 

 Femisa pumila, Wailes, Zoologist (1856), 5074; Westwood, Ent., 

 Annual (1862), 129; Healy, Ent., v., 211-212. F. rubi, Boie, 

 Ent. Zeit. Stett. (1848), 340. 



Black, shining, scarcely pubescent. Antennae longer than the 

 abdomen, moderately thick, and covered with a short pile; pale 

 fuscous underneath. Head narrower than the thorax, very smooth, 

 shining and glabrous ; labrum piceous ; palpi testaceous. Thorax 

 smooth, shining, covered with a microscopic pile seen only side- 

 ways. Tegulae black. Abdomen about the length of head and
