The larvae of the Dynastlnte appear to be intermediate between 

 those of the MelolontiilnvE and the Cetoktim. That of Xylo- 

 trupes r/ideon, L., is figured and described by Schiodte (Nat. 

 Tidsskr. ix, p. 287, pi. viii), who also gives details of the larva of 

 Oryctes nasicornis, L. (p. 290, pi. x). They are typical Lamelli- 

 corn larva?, and, as in the MelolojnthlntE, they have the trans- 

 verse furrows of the segments well marked and the same formation 

 of the anal segment and opening. They resemble the Cetoniid 

 larvae in having the general form shorter, the head narrower than 

 the body, and the mandibles toothed and furnished on their upper 

 surface with a transversely striated area; the upper surface is 

 covered with short spines, and is more or less hairy. 



Several important genera are represented in the Indian region, 

 among them Heteronychus, Dipelicus, Trichogomphus, Eupatorus, 

 Xylotrupes, and Chalcosoma. Eupatorus contains two or three fine 

 species which are peculiar to that region.

The members of the subfamily Cetoxiij^e are remarkable for 

 their beauty, a point in which they run the Ruteli^tE very close, 

 although, like the latter group, they possess many inconspicuous 

 as well as large and conspicuous forms. The huge Goliath beetles 

 of Africa are worthy of being classed with Megasoma, etc., as the 

 largest of the Coleoptera, and the size varies down to quite small 

 insects (Oxythere.a, etc.). In many of the genera there is no 

 sexual dimorphism, but in some, e. g. Cyphonocephalus, it is very 

 marked, the head (and sometimes the prothorax) of the maley 

 being armed with horns or excrescences. The species vary much 

 in appearance, the hairy Trichii looking like large bees as they fly, 

 and appearing perfectly distinct, at first sight, from the ordinary 

 Cetoniid forms. There seems to be a strong relation between
