NEW BRITISH SPECIES, ETC., IN 1867. 75 



Mr. Crotch states that M. Allard, having recognized that 

 his T. lateralis was not the same species as Illiger has de- 

 scribed under that name, has proposed for it the name first 

 above referred to. 



Mr. Waterhouse's insect, identical, as I believe, with this 

 species, is allied to T. melanoccphalay differing from it in 

 being smaller, and having less evident shoulders to the elytra, 

 which are more deeply punctured, the punctures running 

 somewhat into striaB. 



Dr. Sharp has sent me an insect taken in some numbers 

 in a salt marsh near Dumfries, which I am unable to sepa- 

 rate from a type given me by Mr. Waterhouse of his 

 species.

teucril, All. (olim) ; Crotch, Cat. 

 M. Allard refers his T. teucril to this species. It represents 

 the T. minuscula of Mr. Waterhouse's Cat., but seems to differ 

 from the true species of that name in its rather more robust 

 shape and clearer rufo-ferruginous colour, the much less 

 close, coarser, and more serial disposition of the punctures 

 of its elytra, ^vhich are, moreover, individually more ob- 

 tusely rounded behind.

Mon.), 273, 97. 

 Described by M. Allard from four specimens taken by 

 Dr. Power, resembling the recently described T. gracilis^ 

 Kuts. (which, itself, resembles small T. ochroleuca, without 

 the blackened posterior femora), but differing from that 

 species in having the vertex, scutellum, sutural margins of 

 the elytra, breast and abdomen brown; the joints of the
