Dr. Roy DANIELSSON of Lund was kind enough to send me on loan the holotype of Blennocampa recta C.G. Thomson, 1871 which unequivocally showed a differently construct­ed frons, since it had in its lower half a deep, narrow channel. The types of Fenusa nigripes Konow, 1907 was kindly lent by Dr. J. OEHLKE of Eberswalde, and the comparison of the two types revealed, besides several other features, the distinctness of the two species. The last instar larva is light yellowish white with light brown markings. The head is flattened and is mostly brown, maxillary palps and labial palps ringed with light brown, lab­rum and preclypeus light brown, postclypeus and frons yellow, on either sides of frons dark brown. Antenna 3-jointed. Ocellar field dark brown. Pronotum in the middle along a narrow stripe yellow, elsewhere dark brown. Meso- and metanotum with only two dark brown spots dorsally. Thoracic legs light brown with a simple hooked claw. Prosternum light brown, meso- and métasternum at most with a light brown spot each. Prolegs from 2nd to 8th seg­ment present, all of them on outer side brown-ringed basally, 9th segment also marked with a brown spot but no prolegs apparent, above legs stigmata light brown. Anal end yellowish white, not particularly marked. Fig. 1. Mines of Hinatara nigripes Knw. in Acer cam pestre The leaves of Acer campestre were infected, as a rule, by only one larva, only oc­casionally did I find two larvae feeding in one leaf. In the latter case, they did not occupy a common mine but fed separately in different lobes of the leaf, proceeding from the apex of the lobe along, on both sides, of a main vein (Fig. 1). Usually the larva consumed 3-4 cm' surface area of leaf tissue, leaving both the upper and lower epidermis of the leaf intact. When fully fed it gnawed an exit hole and dropped to the ground wherein it pupated and emerged next year.
