156 Mr. K. G. Blair on the Fabrictan Types of 
Reference to Fabricius’s earliest description is omitted 
from both Gemminger and Harold’s Catalogue and that of 
Borchmann, so that the name is made to date from 1792. 
The species is generally erroneously determined in col- 
lections. The type is a @, with greenish-black thorax, legs, 
and antenne. ‘The ?, with these parts testaceous, was later 
described by Fabricius as H. porrecta, which is identical with 
Chrysomela unifasciata, De Geer. 
The name E. elongata, Fab., must therefore be sunk as a 
synonym of H. unifasciata, De G., and for the species usually 
known by it a new name must be found. J. longa, Gmel. 
(1788), which appears in the Catalogues as a synonym, 
is probably only a Japsus calami, and in any case the 
description refers definitely to the Fabrician species, so 
that the name is not available for H. elongata, auctt. (nec 
Fab.). 
From specimens now in the British Museum from De- 
jean’s Collection it is evident that the mistake had arisen 
at least as early as his Catalogue (1837), and I now 
propose the name dejeani, nom. nov., for the species that 
appears there and in later Catalogues as EL. elongata, Fab. 
Both species are black with a greenish-metallic tint and 
a broad flavous vitta along the disc of each elytron” ; they 
are readily distinguished as follows :— 
Vitta embracing the 5th, 6th, and 7th intervals, but not 
extending beyond them except near the base, where it is 
suddenly expanded to reach the margin; punctures of 
median row on each interval as large as those of the striz. 
—dejeani, nom. noy. [ =elongata, auctt. (nec Fab.) ]. 
Vitta embracing the whole of the 4th interval and 
encroaching slightly upon the 8rd and 5th; punctures of 
median rows on each interval distinctly smaller than those 
of the striz.—wnifasciata, De G. [=elongata, F.=longa, 
Gmel.=porrecta, Fab.=vittata, Illig. (Dej. Cat.) |. 
Family Melandryide. 
10. Stenotrachelus eneus. 
Lagria enea, Fab, Syst. Ent, p. 124. In Insulis Americ. 
The habitat is evidently erroneous, the species being 
holarctic in distribution. 
* N.B.—E. unifasciata, De G., is sexually dimorphic, as noted above.
