ftlf-bough I think C. 4--macti!ata will come in the aurata and gemina group. I 

 hope, before long, either to write, or see written, a description of the female. — •

Hemiptera near Norwich. — Chilacis ti/phcB : I recently commissioned a friend 

 to bring me some heads of Typha latifolia froin the pit at Swanton Morley, where I 

 swept up an example of this species last year, and in an old head of last year which 

 had assumed the floecose condition, I found several defunct specimens. DerepJiysia 

 foliacea : I beat a specimen of this species from ash yesterday. Heterocordylus 

 unicolor : I took three worn examples off Q-enista tinctoria at Wacton on the 4th 

 instant. Loxops coccineus : this species, for which I have been on the look out for 

 several years, I took off ash-trees yesterday ; I could not get more than two exam- 

 ples from any one tree, and it was decidedly a case of no " keys " no bugs. Typhlo- 

 cyha jucunda : this species occurs sparingly on alders just now in two or three places 

 in the Norwich district. I have also met with the following : Eupteryx Germari, 

 in two localities, on Scotch firs which have evidently been planted. Pxylla pruni, 

 on blackthorn, immature late in August (I have one mature ? from fir in March). 

 Psylla visci, the spring brood, larvw, pupae and perfect insects on mistletoe, 25th 

 June ; and Trioza lianiatodes off Salix alba September 16th. — James Edwaeds,

Dr. J. Spangherg's ivories on Hemiptera. — I have recently received from Dr. 

 Jacob Spangberg, of Upsala, two excellent monographic memoirs, of which he is the 

 author, and which are devoted to the insects comprised in two genera of Homopterous- 

 Hemiptera. The first is entitled, " Species GyjDonse generis Homopterorum " 

 (Bihang till Svenska Yet. Akad. Handl. Band, v, No. 3, 1878), in which 96 species 

 are critically arranged and described, many for the first time. The second, " Species 

 Jassi generis Homopterorum" (Ofv. Xongl. Yet. Akad. Forhandl., 1878), deals with 

 51 species in the same manner. An examination of these memoirs exhibits a method 

 and thoroughness of work which will be appreciated by all who have to consult the 

 same. Unfortunately, but perhaps, inevitably, the work of the late Mr. Walker 

 has been ignored. British entomologists who know the risk and difiiculty of identi- 

 fying insects from Mr. Walker's descriptions without examining the types in the 

 British Museum, can well realize that the writings of that author must be scaled to 

 continental workers ; but whilst the descriptions and types remain in existence, the 

 names will always stand in nomenclature, at least in this country, and their resur- 

 rection from time to time will add to the difficulty of synonymy abroad. To 

 insular prejudices it is not gratifying to see such good work being done on the 

 continent, and the catalogues of our National Museum, for such valid reasons, 

 rejected and ignored. — W. L. Distant, 1, Selston Yillas, East Dulwieh : \)ih

DescriplioH of the ? q/" Trioza atripliuis, Lichtenstein. — I am enabled to give 

 a description of this sex of the insect through the kindness of M. J. Lichtenstein, 

 who forwarded to me the three larvae which he mentions at page 84, ante, as having 

 found after opening about 100 leaves of Atriplex patula. Two were dead on their 

 arrival, but the third, although in a weakly state through want of food, the portion 

 of the plant sent with them having dried up, soon recovered on being placed on some 

 fresh leaves which I gathered for it. It remained very nearly on the same spot
