advisability of attributing one plant to an insect: it was first found on 

 Selianthemum guttatum, tlien on Poterium muricatum, and now on 

 Epilohium. 



GrEAPTODEnA OLEBACEA. 



The common insect originally known to us by tbis name, and 

 afterwards referred to pmilln, Dufts., must, according to M. AUard, 

 who has examined some of my specimens, revert to its former appel- 

 lation. Continental examples of oleracea sent to me by tbat authority 

 also entirely accord with our insect. M. Allard corroborates our 

 O. montana. 



TlIYAMIS FERRUGINEA, Foudr. 



This species was recorded as British by the late Mr. G. R. Crotch, 

 but is not included in Dr. Sharp's Catalogue, on account (I presume) 

 of the reference of Dr. Power's exponent of it to T. Waterhousii, 

 Kuts. M. Allard, however, has returned to me as T. ferruginea two 

 examples, one belonging to Mr. Champion (taken at Caterham, July, 

 1873) and another from my own collection (I have two specimens). 

 These may readily be known from T. flavicornis and peUucida by their 

 smaller size, and much stouter antenna", of which the five or six apical 

 joints are blackish ; and from the latter also by their much coarser 

 punctuation. From T. Waterhousii, in which the apical joints of the 

 antenna) also are blackish, they may bo known by their smaller size, 

 rather stouter antenna, and more coarsely punctured thorax and elytra, 

 which are much nari-ower and of less gelatinous appearance. 



Thyamis atriceps, cerina, and medicaginis, are corroborated as 

 British by M. Allard. 



PSTLLIODES INSTABILIS, Foudr. 



Corroborated as British by M. Allard, from a specimen in my col- 

 lection. This insect differs from P. cuprea in its smaller size, darker 

 colour, stouter and darker legs, and more shining head and thorax, of 

 which the punctures are not so close.
