NEW BRITISH SPECIES, ETC., IN 1868. 57 



unable to refer to any described species. I have subsequently 

 found another specimen in the same locality ; and there 

 appear to be two very old examples of it from " Gog 

 Magog," Cambridge, in Dr. Power's collection. 



It has been sent to Herr Kutschera, who returns it as a 

 new species, and is most closely allied to T. tahida (verbasci, 

 Auct.), compared with which it is smaller (the largest speci- 

 men being rather less than the smallest tahida)^ not so light 

 in colour, with the thorax more evidently and the elytra 

 more strongly and less closely punctured, the third joint of 

 the antennae not longer than the second, and the spur termi- 

 nating the posterior tibiae very much shorter and scarcely 

 perceptibly curved. 



59. THYAMiSLURiDA,Scop.,Kutsch.,Allard ("L'Abeille";, 

 nee Gyll, ; G. R. Crotch, Cat. Brit. Col., Ed. 2. 



The species formerly known to us as T. hrunnea having 

 been referred to T. castanea, it now appears that the true 

 hi'unnea, Dufts. {lurida^ Gyll., var. i), is mixed in our col- 

 lections with T. larida, Scop. Both species are stated to 

 vary much in colour, and apparently also in punctuation ; 

 but hrunnea is to be distinguished by much greater con- 

 vexity and by its elytra being much more curved laterally, 

 with the shoulders effaced, no projecting humeral callus, and 

 the apex of each elytron strongly rounded. T. lurida is 

 said by M. Allard to have only some analogies (!) with T, 

 hrunnea^ and they are separated by about fifty pages in his 

 work ; but it will certainly give any one who has a moder- 

 ately large series of old lurida a puzzling day's work before 

 he will be able to satisfy himself as to the specific difference 

 of these two insects.
