has not stated tlie number of abdominal feet, as that is a very 

 important point, considering tlie uncertainty that exists regarding 

 the systematic position of the smaller species of Dineura. Mr 

 Cliarles Healy has found a saw-fly leaf-miner on the Ranunculus, 

 but, unfortunately, he has never succeeded in rearing the fly ; nor 

 has despccta been recorded as a native of Britain. Perhaps this 

 note may induce some one to try the breeding of the larvae from 

 the buttercup mines. 



A. Antennae 10-11 jointed; body oblong half depressed, black above and 

 beneath ; pronotnm and tegulae white. Feet white. Wings scarcely smoky. 



Wings with a smoky fascia in the middle; sides of abdomen with white 

 marks — nemorata. 



Wings without a smoky fascia — aceris. 



Phyllotoma nemorata. 



Tenthredo nemorata, Fallen, Acta Holm., 1808, 47, 23. Druida 

 parviceps, Newman, Ent. Mag., iv., 261; v., 484 ; Healy, Ent. 

 No. 62, p. 208. Phyllotoma tenella, Zaddach, Besehr. neuer oder 

 wenig bekant. Blattw., 28, pi. 1, f. 17; van Yollenhoven, Tidjs. 

 Ent. xviii., 39-42, pi. 4. F. nemorata, Thomson, Hymen. Scand., 

 i., 176, 1. 



Black, shining; antennae shorter than the abdomen, 10-11 

 jointed, beneath fuscous testaceous; inner orbits of the eyes and 

 face yellowish white; a black line above the epistoma; mandibles 

 piceous; palpi white. Pronotum and tegulae white ; cenchri 

 large, dull white. Abdomen with the sides marked with white 

 dots, usually oblong. Feet white ; base of coxae and femora 

 black. Wings hyaline at the apex, a little smoky at the base, 

 with a large smoke-coloured fascia, extending from the stigma to 

 the bottom. Length 2-2^ lines. 



From the next species nemorata is distinguished by the fascia on 

 the wings, the white spots on the abdomen, and larger size. The 

 male is unknown. 



P. leucomela, Klug. is probably identical with this species; but 

 the description is not very good, and no mention is made of any 

 markings on the abdomen. 



The egg is deposited near the tip or edge of a birch leaf, in 

 which the larva afterwards lives solitary. There are two broods 

 in a year: the first, in June and July; the other later on in the 

 autumn, the larvae being found as late as October.
