staut in Rhinocol<i, at once sliow tlieir distinctness. According to Dr. Flor, to whom 

 I am indebted for specimens, this species is not uncommon from Juno to August on 

 dry hilly places, on heath. 



Aphalaba affinis, Zett. — Deep black, dull. Head with scarcely discernible punc- 

 tures. AntenncB yellowish- white, two basal and two apical joints black, apex of 

 2nd joint sometimes whitish. Pronotum much deflected ; mesonotum on the 

 sides at the base of the elytra generally yellow, brownish-yellow, or brownish- 

 red, seldom black. Jllytra almost clear transparent, with a very faint yellowish 

 or yellowish-brown shade, sometimes darker at the apex than at the base ; 

 nerves clear, fine ; nerve adjoining the apex of the clavus with a black spot at 

 the dorsal margin. Legs yellowish- white ; coxce,fidcra, and tliighs, brown or 

 black, apex of the latter yellow. Abdomen black ; genitalia of both sexes as in 

 A. polygoni. 



Found, Dr. Flor says, on moory meadows, also on Pinus Abies, from June to 

 September. Tliis is a species I do not possess, and the tree named, to which a large 

 number of individuals of the various genera seem to be attached, I have rarely had 

 an opportunity of searching. 



Aphaiara artemisi-E, Forst. — Clear green ; mesonotum sometimes with reddish- 

 yellow streaks. Antennce dusky yellow or green, 4 — 7 sometimes brown at the 

 apex, 8th at apex, and 9 and 10 entirely, black ; Ist and 2nd joints underneath 

 frequently brown. Mytra white, almost transparent, with very minute black 

 punctures frequently confluent, and sometimes so thickly disposed as to render 

 the disc opaque. Legs green. 



Forster says he received six ? from Dr. Scholz with the remark that he found 

 them on sandy places at the base of Artemisia campestris, a rare plant in this country, 

 and, according to Babington, only found on sandy heaths in Norfolk and Suifolk. 

 Flor states that with him the insect was very common on dry mountain meadows and 

 heath, as well as on Artemisia, from June to August. I only know this species from 

 the descriptions of the authors cited ; but it seems to me, from the latter's observa- 

 tion, that we ought to get it here. I shall bo glad to see or hear of examples of any 

 of the foregoing having been found, to enable me to add them to the continuation of 

 my paper on the group. — Id. : July 5th, 1876. 



Notes on some species of PsyllidcB. — Under this heading (p. 42 ante) I cited 

 Kaltcnbach with respect to Psylla ixophila, " Frauenfeld." I could not find the 

 name at the reference given to the " Verhandlungen," and the volume has no index 

 of species ; but I have since discovered that Kaltcnbach was trebly wrong. First, he 

 puts " exophila" instead of "ixophila " (the latter and correct name, however, is in 

 the Index of his book) ; secondly, he has " Frauenfeld " instead of " F. Low," as 

 the author of the specific name ; thirdly, he has " Verhandl. k. k. z.-b. Ges. Wien, 

 18G2, p. 100" — the last should be "105." Dr. Franz Low there described the 

 pupa and imago, and figures are given on a plate. Of the pupa he found a single 

 example only, at Vienna, 28th April, on a leaf of mistletoe, and it remained per- 

 fectly stationary thereon for eight days, when the imago was developed. He believes 

 it is not the P. visci of Curtis, but his opinion that it is distinct is mainly founded
