Chrysomelidce, in Linrnsan and Banhsian Collectiuns. 23 



31. Chrys. chrysocephala (Faun. Suec. 166, 5S5). Is a small 

 cryptocephalus with a black thorax, and blue elytra ; the mouth, 

 and a V-shaped mark on the forehead, the three basal joints of the 

 antennae, the anterior margin of the thorax, and the lateral margin, 

 on the fore part, as well as the four anterior legs, pale testaceous ; 

 the under parts and the hind legs black, the elytra punctate- 

 striate — an insect, in fact, which agrees with Gyllenhal's descrip- 

 tion of Crypt, functiger. There is but one specimen, and that 

 with the label attached. If this really be the Chrys. chrysocephcda 

 of the " Fauna Suecica," which I fully believe to be the case, Lin- 

 naeus is of course wrong in attributing saltatorial powers to the 

 insect, which has given rise to his description being referred to 

 the Psylliodes chrysocephala. 



32. Chrys. Hyoscyami (Faun. Suec. 166, 5SQ^ ==. Psylliodes, id. 



33. Chrys. atricilla (Faun. Suec. 166, 537) is certainly the 

 Psylliodes affinis of most modern authors = Haltica atricilla, 

 Panzer. The posterior tibiss are produced beyond the insertion 

 of the tarsus, the elytra are punctate-striate, and the colouring as 

 described in the '* Fauna Suecica." 



34. Chrys. erythrocephala (Faun. Suec. 1G6, 538) is a Psyl- 

 liodes, certainly nearly allied to Ps. chrysocephala. It is rather 

 smaller and shorter ; black, with blue elytra ; the head entirely 

 red, the thorax more thickly and more distinctly punctured, the 

 elytra more finely punctate-striated, the punctures not only being 

 very delicate, but often somewhat remote from each other ; the 

 interstices almost impunctate; the anterior legs piceous, with the 

 knees and feet testaceous ; the hinder femora black, the tibiae 

 rufescent. I have seen three specimens from Germany agreeino* 

 with this Linnaean insect, which I have little doubt is the Haltica 

 chrysocephala, var. c. of Gyllenhal, iii. 569, [The species has since 

 been described in M. Allard's Monograph, under the name PsyU 

 liodes rujilabris.^ 



35. Chrys. helxines (Faun. 8uec. 167, 540). Two specimens 

 on the label, one is the Crepidodera fulvicornis of most modern 

 authors (Cr. helxines of Foudras), the other is Cr, aurata of Mar- 

 sham =: Crepidodera, id. Foudras. Linnaeus, it will be observed 

 says of the insect, " Antennis pedibusque omnibus testaceis." 



36. Chrys. exoleta (Faun. Suec. 167, 541). One specimen 

 only. This is a Thyamis (or Teinodacfyla), and, after a careful
