apex of the tibisc and tarsi black. As it approaches the perfect state, the abdomen, 

 especially towards the apex, becomes clothed with long, white, curled hairs or fila- 

 ments, and the head and elytra-lobes also in a more or less degree. They live on 

 the under-side of the leaves of the ash {Fraxinus excelsior), in the beginning of 

 July, but do not cause any deformation, and are generally found in little colonies, 

 partly, or sometimes entirely, enveloped in a fine, soft, loose, farinose secretion. 

 When disturbed they are very active. 



In the " Yerh. der k. k. zool.-bot., G-esellschaft in Wien," for 1879, p. 587, Dr. 

 Franz Low gives his reasons for the separation of the above species and Ps. fraxini 

 from the genus Psylla, Foerster, and other authors, and amongst other characters he 

 points out the remarkable shape of the genital processes (Zange) of the S "when 

 viewed from the side. In Ps.fraxinicola these are hatchet-shaped, and in Ps. fraxini 

 hammer-shaped, and are easy of recognition with the aid of a pocket-lens. There 

 are only two other Eui-opean species known {discrepans and melipTiila), which, like 

 ours, are also attached to the ash. — Id. : March 9th, 1886. 



Note on Trioza remota, Foerster, together loith a description of the nymph. — This 

 Trioza was described by me in the " Transactions of the Entomological Society," 

 for 1876, p. 557, under the name of T. hcematodes, which is a synonym of it, as are 

 also T. cinnaharina, Forster, and T. dryohia, Flor. It is a common species, and is 

 frequently found on fir trees, if growing in the vicinity of the oak on which it has 

 passed through its various stages, thereby misleading collectors. 



The nymph is of a pale green colour, flat, broad, about three-fourths as broad 

 as long. Head : anterior-margin almost straight, with a border or fringe of short, 

 pale, shining, fine stiff hairs placed closely together ; eyes reddish-brown. Antennae 

 short, whitish, or very pale greenish, apex brown. Thorax : upper-side very pale 

 green, more or less spotted with yellow down the middle. Elytra-lobes almost 

 white in front, extending beyond the head ; costal margin with a fringe of short, 

 pale, shining, fine stiff hairs placed closely together. Abdomen very pale green, 

 down the middle more or less spotted with yellow, outer margin with a fringe of 

 hairs similar to those on the head and elytra. Legs very pale green, or almost 

 white, apex brown. 



Tliey are to be beaten at the end of March and beginning of April from oaks, 

 on the under-side of the leaves of which trees they live, apparently singly, and 

 without causing any deformation. — Id. : March 10th, 1886. 



Neiospaper Entomology. — A correspondent has forwarded a cutting from a 

 Scotch newspaper, which we reproduce. The words italicised by us seem to indicate 

 that a knowledge of elementary entomology is desirable in some quarters in Great 

 Britain, as well as in South Africa : — 



" A Scourge of Caterpillars. — Much alarm has been caused in the Camperdowu 

 distinct of Durban, says the Cape Times of March 6th, by the scourge of armies of 

 caterpillars, which have appeared amongst the forage crops. One army extends a 

 mile and a half deep, and has swept over seventy acres of fine forage. It is now 

 going in a westerly direction. Another, comprising many millions, has eaten every 

 bit of forage in one district. By to-day the two armies will have joined, and threaten 

 Boston. It is feared it will do more damage than the visitation of the 1878 pest.
