eyes projecting. In many the tongue is short, and advances 

 but little beyond the emargination of the mentum. 



Here, this emargination has no tooth. The mandibles are 

 strong, and the labrum is strongly emarginated, and almost 

 bilobate. Such are — 



Pelecium, Kirby. 



The last articulation of the external palpi is in the form 

 of a hatchet. The tongue is short. The body is oblong, 

 more narrow in front. The first four articulations of the 

 anterior tarsi of the males are in the form of a reversed 

 triangle, furnished with a brush underneath, and the fourth 

 is bifid. 



The species of this sub- genus, and the following, are 

 proper to South America, Pelecium cyanipeSy Kirb. Trans. 

 Lin. Soc, XII, xxi. 1. 



Here, the emargination of the chin presents a tooth. 

 The mandibles are generally small and moderate in the 

 others. The labrum is entire, or but very slightly emargi-

Some approach to pelecium, in regard to the exterior palpi, 

 terminated also by a larger articulation, in the form of a 

 hatchet, or reversed triangle. Their head is always small, 

 and the corslet is orbicular or trapezoid,

In the males of which the first articulations of the anterior 

 tarsi are in the form of a reversed triangle, and compose the 

 palette ; they are furnished with a brush underneath, and 

 the fourth is bifid. 



The head and mandibles are proportionally stronger than 

 in the following sub-genus. The external palpi are less 

 elongated, but more compressed at the end. The body is
