Those, in which the maxillary palpi are much longer than the labial, the ligula is emarginated, and the abdomen rounded and entire at the extremity, have been generically distinguished by the name of HEDYOHltUM. Those which, similar to the Hedychra in the relative proportions of the pal pi., have a rounded and' entire ligula, form two genera. In the first OJ' ELAMPus, Spin. The mandibles have two teeth on the inner side; the abdomen is entire and rounded at the end, and the posterior extremity of the thorax is furnished with a spine. In the second, or CHRYsrs, Spin., there is but a single dentation on the same edge; the abdomen is more elongated, truncated at the end, and frequently a transverse range of large punctures at the same extremity. In this subdivision comes the most common species in Europe. C. ignita, L.; Panz., Faun, Insect. Germ., V, 22. Blue mixed with green; abdomen golden cupreous-red, and terminated by four dentations. Sometimes the thorax is narrowed before; the abdomen is almost ovoidal without being arched, and presents four segments in the females and five in the males. CLEPTEs, Lat.

Method., have given the generic appellatio~ of P_yna to certam Insects closely allied, according to them, to StUbum, hut m wh1~h the met!lthorax presents a scutelliform projection, the head offers n~ depre~s10o, an.d where the simple eyes are arranged in a triangle, those on the stdes bemg cons•derably distant from the ordinary eyes.
