382 niYTOPHAQA. [Crept Jodera. 



C. nitidula, L. (Choi Goide* nit iduln, Foiulr.). Oblong-ovate, rather 

 convex, shining ; head and thorax golden green or coppery, elytra nigro- 

 coernleous, violaceous, or greenish-blue ; head with vortex very shining, 

 scarcely punctured, antennae reddish-testaceous, fuscous towards apex ; 

 thorax transverse, broadest before, middle, rather thickly and distinctly 

 punctured, with a strong transverse furrow at base bounded on each 

 side by a longitudinal impression ; scutellum dark blue ; elytra at base 

 a little broader than thorax, with shoulders marked, punctured in 

 distinct and not very regular rows, with the interstices, especially the 

 second, fourth, and sixth, furnished with rows of rather strong punctures; 

 legs reddish-testaceous, posterior femora dark. L. 3-4y mm. 



On willows and aspens ; rare; near London and Bristol (Stephens); Littlingtou, 

 Cambridge, one specimen, September, 1863 (Power) ; Dover (C. G. Hall) ; Devon 

 (Parfitt) ; Knapps Wood, near Weston-on-the-Green, Oxfordshire (Mattln \vs) ; 

 Scotland, doubtful, the .only record beiug " Kaeliills, Rev. W. Little," Murray's Cat. 

 Mr. Johnson records it from Armagh, but I have not seen the specimens. 



C. helxines, L. (CJialcoides helxines, Foudr.). Obbng-ovate, in 

 shape much resembling the preceding, but easily distinguished, apart 

 from its colour, by the stronger punctuation and the almost smooth 

 interstices of the elytra; the colour is variable, being usually coppery 

 red or aeneous green, with the head and thorax, as a rule, almost uni- 

 colorous with elytra; occasionally the upper surface is coeruleous or 

 cyaneous, but this variety is very rare ; it is the Chrysomela cyanea of 

 Marsham ; head very finely punctured, antennae entirely reddish-testa- 

 ceous or gradually and slightly inf uscate towards apex ; thorax strongly 

 punctured, almost twice as broad as long, broadest before middle, with 

 a strong transverse furrow and longitudinal impressions at base; 

 elytra with rows of strong and deep punctures, interstices very finely 

 punctured; legs reddish-testaceous, posterior femora dark. L. 3-3 j 

 mm. 



On willows, sallows, and poplars ; generally distributed and common in the London 

 and South-eastern, and probably the whole southern districts of England ; somewhat 

 local in the Midlands ; Swansea ; Lincoln ; Manchester district, general ; Bold says 

 that although stated to be very common in the Northumberland and Durham district 

 on willows, yet he has never seen a local specimen, and Dr. Sharp records it with 

 doubt from the Solway, Tweed, Forth, and Clyde districts of Scotland, and remarks 

 that he has never seen a Scotch specimen of the sub-genus Chalcoides except C. 

 smaragdina, to which insect, probably, the C. helxines of Murray's catalogue ought 

 to be referred; Ireland, Dublin and Belfast. Weise (I.e. p. 717) regards C. cyanea, 

 ., as a distinct species. 



C. chloris, Foudr. This species is of a unicolorous greenish-golden 

 coppery colour, the coppery colour usually prevailing over the other 

 tints, and may easily be known from the allied species by its oblong, 

 subparallel, and more elongate form, and by having the first four joints 

 of the antennae of a bright reddish-yellow colour and the remainder 

 black, the colour being sharply defined ; the rows of punctures on the 

 elytra are finer than in tho preceding species. L. 2 3 mm.
