In mounted specimens the rostrum is often veryconspicuous, and as a rule the front pair of legs are much moreprominent than the antennae.

Lachnus longipes, Dufour. This species is found onoak, and often on youngshoots from oak stools. Theeggs, however, as representedin fig. 286, are the mostconspicuous. They may belooked for in late autumn orduring the winter months. In early summer the apter-ous viviparous females maybe found in masses on theshoots of oaks which growas suckers from the stoolsor stumps of previouslyfelled trees. They arefairly large in size, ofoval form, and of a uniformly deep-brown colour. Eyes black, andcornicles Fig. 2S6.—Eggs of Laehnus liingipes on oak. Photo-graphed in winter ; leaf added for identification. Lachnus viminalis (Fonsc.) This species is found fairly common in some parts of the countryon willow or osiers, and very harmful to willows and osiers in partsof South England. Wasps are greatly attracted to where they occur. 312 FOREST ENTOMOLOGY. It is apt to be confounded with Melanoxanthus salicis, one of themost salient points of difference being the joints of the antennae. The other species described by Buckton in his Monograph areL. picece, which is said to be very abundant on silver fir and alsoon spruce near London ; L. pinicolus, on larch and Scots pine; andL. macroceplialus, on spruce. Genus Phyllaphis. The following generic characters are from Buckton :— Bostrum very short. Head convex, smooth. Antenna? moderately long, the third joint about double thelength of the fourth; the fifth and sixth joints equal, the sixthfurnished with a representative nai
