One of the most peculiar genera belonging to the family isPteroloma, GylL, which superficially resembles Nebria and wasincluded by all the older workers under the Caeabid^e, untilErichson (Arch. Naturg. 1837, i, p. 119) pointed out its affinitiesto the Silphid^: ; it is remarkable for possessing two ocelli on. Fig. 39.—Necrophorus X 3. (After Schiodte.) the vertex, and the Japauese genus Camioleum, Lewis, which alsohas two ocelli, ought perhaps to be referred to the is another genus of Silphid^e, closely allied to Pterolomarwhose members very closely resemble species of Lebia; twospecies are known, one of which, A. lebioides, Hope, was originallyfound in the Himalayas. The Silphid^; are for the most part confined to the NorthernHemisphere and are characteristic of cold and temperate countries;very few occur in the Tropics. Necrodes, Necrophorus, Silphar —LEPTIJfIDJE. 85 and Choleva are each represented in India by one or two species,and possibly examples of the Liodexoe, etc., may be discovered,but no one as yet appears to have worked at the group, so far asthe Indian fauna is concerned. The SphvEritldyE and Clambidte have been classed with thevSiLPHiDiE, but through the wing venation the former
