I HAVE already stated (Ent. Mo. Mag., Sec. Ser., Vol. xvi, 
p. 223) how on comparing any original series of 180 speci- 
mens of a Zetropium, reared by myself May—June 1905, 
at Leighton Buzzard with the series of 7. luridum, L., in 
the British Museum, I was a little doubtful as to their 
identity with the latter species. 
Accordingly I submitted a specimen to M. Bedel for his 
opinion, who kindly drew my attention to a new species, 
T. gabrieli, lately described by Herr Weise, as follows :— 
Elongatum, nigrum, pedibus fulvis aut ferrugineis, fronte con- 
vexiuscula, haud canaliculata, prothorace disco nitido, crebre 
subtilius punctato, latera versus opaco, creberrime ruguloso-punctato 
et subtilissime granulato, elytris opacis, elevato-lineatis. 
Long. 95-14 mm. 
Var. a. Elytris obscure ferrugineis, femoribus nigris, tibiis tarsisque 
rufo-piceis. 
(Deutsche Ent. Zeitschr., 1905, p. 136.) 
With this information I handed over my material to 
Dr. D. Sharp for determination as he was working at the 
genus at the time, with the result that he pronounced 
the Leighton Buzzard insect a new species, naming it 
T. crawshayt and describing it thus :— 
Fere angustum, subdepressum, nigrum; antennis, tibiis, tarsisque 
piceis ; vertice in medio haud, vel vix, depresso; prothorace vix 
transverso, ubique crebre, fere zequaliter punctato (i.e. areis levigatis 
fere nullis), margine basali obsolete elevata. 
Long 12-16 mm. 
(Ent. Mo. Mag., Ser. II, Vol. xvi, p. 271.) 
Dr. Sharp suggested the possibility of this insect 
ultimately proving identical with 7. gabrieli, but, in con- 
sideration of the entirely red legs of the single specimen 
of 7. gabricli communicated by Herr Weise, as compared 
with the black femora constant throughout my long series,
