Thelarvae (Fig. 444, larva of an unknoAvn species) moultseveral times, and when about to transform make no co- s- ^coon, the beetles appearing in about six Aveeks. Dr. Lecontesays that the distribution of the genera of this family is veryremarkable. Of those Avithout Avings scarcely any are commonto the two continents. With the exception of three, they arenot represented in North America, east of the longitude ofthe mouth of the Platte or Nel)raska River; from that pointthey increase in number of genera, species and individuals,until in California they form the characteristic feature of theinsect fauna. We can only notice a fcAv genera, interesting to the generalreader, and refer the special student, as heretofore, to Dr, Le-contes able treatment of the Coleoptera previously cited. The genus ^, in Avhich the hind wings are obsolete, doesnot occur in this country, being represented by numerous spe-cies of Elodes and Promus. The European Blaps mortisaga is 474 Fig. 445. the Church-yard beetle. Dr. Pickells states, according to West-wood, that one of these beetles was immersed repeatedlyin spirits of wine, but revived after remaining therein allnight, and afterwards lived three years. The larvtfi are eatenby the women in Egjq^t, after being roasted. In Upis the legs are long, with small tibial spurs, while thetarsi are clothed beneath with a silky, golden pubescence, the hind tarsi being long, andthe epipleurae are graduallynarrowed towards the baseof the eljtra. Upis ceram-boides Linn, is a fine large,deep purple black beetle,Avitli roughl}^ shagreenedelj-tra, and is found underthe l)ark of trees. In Tene-brio the body is long ovateand winged, the legs areslender, the femora swollen less than usual, with larger tibialspurs ; the tarsi are clothed with a rigid pubescence, and theepipleurae exten
