DISCOVERY OF TRIOZA CENTRANTHI, VALL., IN ENGLAND. 

 BT PHILIP B. MASON, F.L.S. 



About the middle of August, 1894, Mr. T. Gibba brought to me a 

 plant of Valerianella dentata, Poll., which he had gathered in a corn 

 field near Bretby, Derbyshire. It was curiously deformed, and on 

 looking at it closely the deformity n^as found to be due to the crowding 

 together of the flowers and the great broadening of the bracts ; the 

 upper portions of the bracts were reflexed, and each bract was found 

 to shelter a Psyllid larva. From these larvae, in about ten days, were 

 hatched specimens of Trioza Neilreichi, Frfld. (1864). They are very 

 prettily marked with two bright silvery lines on the dorsal surface of 

 the abdomen. 



Kaltenbach refers to a Psyllafedice, Forst., as feeding on Yale- 

 rianella olitoria. Puton, in his Catalogue (1876), refers to neither of 

 these names, so that I cannot say whether the species infesting these 

 two nearly allied plants be the same or not. At all events it is, I 

 believe, a species of this interesting Family hitherto unrecorded for 

 this country.

[This is a very interesting notice of the first capture of this 

 Psyllid in England, but the appearance of the species in Britain has 

 long been expected. The late F. Low had a comprehensive article on 

 its natural history and bibliography in the " Verhandlungen der k. k. 

 zool.-botan. Gesellschaft in AVien," 1886, from which the following 

 synonymy is extracted : — 



Psylla ce7itranthi,Y allot (1829) ; Trioza acufipenms,'Frst. (1848), 

 nee Zett., nee Flor : Trioza Neilreichi, Frauenf. (1864) : Psylla 

 fedicB (Frst.), Kaltenbach (1874) : Trioza anytilipennis, Futon (1875) : 

 Trioza centrantJii, Andre (1878) : id., F. Low (1886). 



The species lives within deformations the larva makes of the 

 leaves and flowers of Centranthus ruber, C. angustifolius, Valerianella 

 cnrinafa, V. dentata^ V. olitoria, and Fedia cornucopice, in France, Italy, 

 Germany, Austria, and Hungary. It appears as imago from June to 

 autumn, and hibernates. — J. W. D.]. 



Nothochrysa capitata, F., at YorTc. — I obtained a dead specimen of N. capitata 

 from a spidei-'s web at Sandburn, York, on August 6th. — O. T. PoiiiiiTT, Iludders-
