of some species of Chrysomcla, §"c. 189 



vai-ies somewhat in size and degree of punctnation, also 

 slightly in coloration ; the latter (nsually cupreous) being 

 occasionally tinged with metallic blue. Var. A. has the 

 outer limb of the elytra broadly edged Avith rufous. Spe- 

 cimens from Japan are larger and more coarsely punc- 

 tured than those from Continental Asia. The duck-billed 

 shaj^e of the $ organ and the form of the apex of the 

 anal segment of the abdomen in the $ are constant in all 

 the specimens I have examined.

Ch. songorica, Gebl. {sulcata, Fisch.), from Eastern 

 Siberia, cannot be considered as more than a local form 

 of Ch. marginata ; the specimens are usually rather larger, 

 paler coloured and less metallic, and their elytra are often 

 more strongly punctured and the strife more deeply sul- 

 cate, but they vary greatly in all these respects ; the form 

 of the ielum is similar in both.

The present species closely resembles the preceding, 

 and might, at first sight, be taken for a local variety ; it 

 ditiers, however, in the following particulars : — the apical 

 joint of the maxillary palpus is less ovate and more 

 broadly truncate, the basal half of the antenna? is more 

 slender, the third joint being relatively longer than the 

 fourth; the sides of the thorax are also more strongly 

 punctured ; the punctures on the elytra are placed at un-
