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 antennz 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 
Guapuyrus, 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 maxille is dentiform, the outer or ter- 
minal one coriaceous. The thorax is oblong, and the posterior legs 
large *, 
Ampuicoma, Lat. 
Outer sides of the mandibles rounded and arcuated, the inner not 
dentated; antennal club globular; abdomen soft, and all the legs of 
the ordinary size. 
The epistoma is strongly bordered, The anterior tibiz have three 
teeth exteriorly. The four first joints of the tarsi are strongly cili- 
ated in the males. Y 
In this and the following subgenus, the maxille terminate in a 
membranous, narrow, elongated, thong-like lobe. Their palpi are 
hardly longer than the others, and the length of their last joint is 
scarcely greater than that of the preceding one ft. 
In those, such as 
Antuipna, Escholtz, 
The antennal club is formed of free and oval leaflets. 
The epistoma is not bordered before ; the median portion of the 
head forms with it a plate of a long square figure, bordered lafseth, 
and posteriorly. The outer side of the anterior tibiz has f) in the 
The four first joints of the tarsi are dilated and dejyy~ ia 
males. These Insects otherwise resemble the Anyeg or non-salient, 
In the others, the labrum and mandibles are,q, The mentum is 
and some at least of their tarsial hooks a~ 
elongated and pilose.
