Reference to Fabricins's earliest description is omitted 

 from both Gcmmin<^er and Harold's Catalogue and that of 

 Borclnnann, so that the name is made to date from 1792. 



The species is generally erroneously determined in col- 

 lections. The type is a J , with greenish-black thorax, legs, 

 and antennae. The $ , with these parts testaceous, was later 

 described by Fabricius as //. porrecta, which is identical with 

 Chrysomela nnifasciata, De Geer. 



The name E. elongnta, Fab., must therefore be sunk as a 

 synonym of E. nnifasciata, De G., and for the species usually 

 known by it a new name must be found. E.lo7iya, Gmel. 

 (1788), which appears in the Catalogues as a synonym, 

 is jirobably only a lapsns calami, and in any case the 

 description refers definitely to the Fabrician speeigs, so 

 that the name is not available for E. tlongata, auctt. (nee 

 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 

 j)ropose the name dejeani, nom. nov., ior the species that 

 appears there and in later Catalogues as E. 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 striae. 

 — dejcuniy nom. nov. [ = elo7igata, auctt. (nee Fab.)]. 



Vitta embracing the whole of the 4th interval and 

 encroaching slightly upon the 3rd and 5th ; punctures of 

 median rows on each interval distinctly smaller than those 

 of the striie. — i(?iifasciafa, De G. [=e/ongafa, Y. = lo7iffa, 

 Kjiiue\. = porrecta, Fab. = vi7/rt/fl, lllig. (Dcj. Cat.)].

The habitat is evidently erroneous, the species being 

 holarctic in distribution. 



* N.B. — ii. unifascittta, De G^s seximlly dimorphic, as noted above.
