PHTTOPHAGA. 



Clythra Iceviuscula, Ratz. 



This species has a very slender claim, indeed, to be admitted as British, and 

 had better be left out (Eut. Ann., 1865, 77). 



Cetptocephalus tiolaceus, p. 



Of this species, which somewhat resembles a large C. fulcratus, Dr. Power 

 possesses a specimen taken by himself in Cambridgeshire ; it was also taken by Mr. 

 Sidebotham. 



Cryptocephalus hipustulatus, P. 



Tliis appears to be a variety of C. lineola, F., and to bear much the same rela- 

 tion to that species as the vai: bothnicus, L., bears to C. decempunctatus, L. 



Li7ia tremulce, P. 



The true L. tremulee is not British : the L. tremulce of Waterhouse's catalogue 

 := L. longicollis, Suffr., a very common British insect. 



Gonioctena affinis, Suffr. 



This is a very doubtful species, apparently resting on one example, which cer- 

 tainly requires confirmation (Ent. Mo. Mag., i, 278; Ann., 1866, 115). 



Crepidodera smaragdlna, Poudr. 



Dr. Sharp inserts this species in the second edition of his catalogue : it belongs 

 to the C. auraia group, and apparently comes very near tliat species, to judge by 

 AUard's description (Gal. Anisopodes, p. 311). 



Several species of the genus Thyamis appear to be doubtful, as T. nigra and T. 

 fuscula ; the T. melanocephala group requires a careful revision. 



Thyamis distinguenda, Rjg. 



This insect comes nearest to T. atricUla, L., in our list, but differs from it in being 

 on an average of rather larger size, without a dark brassy head and thorax ; it is of 

 less regularly oval outline, and has more perceptible shoulders to the elytra, longer 

 posterior tarsi, and a longer and stronger spur to the tibiae. Found by Mr. Champion 

 on Box Hill (Ent. Mo. Mag., ix, 158). 



Thyamis ferruoinea, Poudr. 



This species was recorded as British by Mr. Crotch, but was afterwards dropped ; 

 it must, however, be again inserted, on the authority of one specimen taken by Mr. 

 Champion at Caterham, and two in Mr. Rye's collection. It differs from T.flavi- 

 cornis and T. pellucida in its smaller size and much stouter antennte, of which the 

 five or six apical joints are blackish, and from T. Waterhousei (which also has the 

 apical joints blackish) in its smaller size, rather stouter antenna;, and more coarsely 

 punctured thorax and elytra, which arc much narrower (Ent. Mo. Mag., xii, 180).
