Text Appearing Before Image:
e clypeus; mentum entire; mandibles very strongly developed inthe nudes; maxilla? with two lobes; anterior coxal cavities closedbehind; intermediate coxa? transverse; mesosternum short, meta-sternum large; elytra not longitudinally sulcate, entirely coveringabdomen; tarsi five-jointed, the last joint elongate. The LucANiuiE, or Stag-Beetles, are among the best known ofthe Coleoptera by reason of the great development of the mandiblesin the males, these being usually regarded as horns by the ordinaryobserver. In some of the exotic species these organs are nearly 208 INTRODUCTION. as long as the rest of the body; they are not, however, verypowerful, and their use is not quite apparent; the female of thecommon British Stag-Beetle (Lucanus cervus, L.) for instance can,with two very short pincer-like nippers, give a much more severebite than the male with his enormous mandibles, and we cannotdiscover any definite purpose, offensive, defensive, or economic,for the development of the latter.

About 600 species have been described ; a considerable numberare found in the Indo-Malayan region, and the Indian region isfairly rich both in genera and species, nearly half the species ofLucanas being found there.
