This tribe consists of the genus Cononotus, of which two spe- cies were found by me under stones in California; they are slen- der, pale brown, finely pubescent insects of small size, having the thorax elongated, and regularly conical in form, and much nui- rowed behind ; the lateral suture is nearly effaced, though still capable of being traced ; the maxillary palpi are very long, and the last joint is large and triangular. It is very dillicult to indicate the aflinities of this genus ; it seems to be equally out of place in any family. It was formerly considered by me as allied to Apocrypha, of the Tenebrionida\ a view adopted by Lacordaire; but the open anterior coxal cavities forbid such an association. The lirst and second ventral segments appear to be connate ; should dissection conlinu this observation, it will point very strongly towards the reception of the genus as a separate family. I â â h i ;iil' Tribe »'»Ix\I. Head prominent, front flattened, prolonged more or less into a broad beak; last joint of maxillary palpi not dilated ; metasternum long, body winged, intercoxal process of abdomen acute ; middle coxic embraced by the sterna, without trochantin ; mandibles not visible beyond the labrum ; anterior coxae conical, contiguous. This tribe consists of species of small size ; two of the genera are represented on both sides of the continent; the third, Tanyr- hiuus, is found in Russian America, and is unknown to me ; the form of thorax is very different from that of the other genera, being described as very much narrower at tip than at base ; the reverse is the case in every genus of the present family known to me; the 5-jointed hind tarsi are also altogether an
