Galerita, Fab. 



Which differ from the preceding sub-genera in their external 

 palpi, the last articulation of which is triangular, or axe- 

 formed, and in their jaws not being dilated at the external 

 edge. The two anterior tarsi of the males are widened. 

 The emarginations of the first four articulations are acute, 

 and their internal divisions are larger and more elongated 

 than the external. The lingua is tridentated at the summit, 

 and its paraglossa? are very distinct. The emargination of 

 the mentum is unidentated. 



Some species, (^Galerita occidentalism Dej. ; G. Africana, 

 ejusd.,) from their ovaliform head, corslet more elongated 

 and narrow, form a particular division. The majority are 

 American.*

Have the exterior palpi filiformed, and terminated by an 

 orbiform and pointed articulation. 



The first four articulations of all the tarsi are dilated ; the 

 first is in the form of a reversed and elongated cone, the lobes 

 of the two following are equal, narrow and pointed ; the fourth 

 is in the form of a heart, or reversed triangle without emar- 

 gination ; the upper surface is excavated for the insertion of 

 the following. The head is nearly ovaliform. 



We shall terminate this section by two, in which the crooks 

 of the tarsi are indented underneath like a comb, and we shall 

 commence by those in which the head ovaliform or ovoide, 

 is separated from the corslet by a sudden decided termina- 

 tion, forming a kind of knob or ball. The penultimate arti-
