COLEOPTERA. 429 



The antennae of some others are composed of ten joints(l). 

 The 



MONOCHELES, IlHg 1 ., 



Only differs from Hoplia in the epistoma, which forms a triangle 

 truncated at the anterior extremity, and in the two posterior legs, of 

 which the thighs are very large and the tibiae short, with a stout 

 hooked tooth at the extremity(2). 



Certain Scarabaeides, closely allied to the last of the. preceding 

 section, and which were at first united with them in the genus Me- 

 lolontha, but in which the paraglossae, or two divisions of the ligu- 

 la, project beyond the superior extremity of the mentum, and where 

 the elytra gape or are slightly remote on the side next the suture, 

 at their posterior extremity, which is either narrowed into a point 

 or rounded, form a fifth section, that of the Anthobii. 



The antenna; are composed of nine or ten joints, the three last of 

 which alone form the club in both sexes. The lobe terminating the 

 maxillae is frequently almost membranous, silky, penicilliform, co- 

 riaceous, and dentated along the inner edge in others. The labrum 

 and mandibles are more or less solid in proportion as they are more 

 or less exposed. 



The Anthobii live on flowers or leaves. 



In some, the mandibles and labrum are salient, and all the tarsi 

 have two entire and equal hooks. 



The antennae consist of ten joints; the maxillary palpi are rather 

 larger near the end, the last joint short or but slightly elongated and 

 truncated; the mandibles are corneous. 



Some of these Insects inhabit the north of Africa and other coun- 

 tries situated on the Mediterranean; most of the others are found in 

 the higher portions of western Asia. 



In these, the first joint of the antennal club is concave and encases 

 the others. In 



Glaphyrus, Lat. 



The inner edge of the mandibles is dentated, and the outer forms 

 an acute angle; the antennal club is almost ovoid; the teguments are 

 firm and the posterior thighs inflated. The maxillary palpi are 

 much longer than the others, with the last joint longer than the 

 preceding one. The inner lobe of the maxillae is dentiform, the
