308 INSECT A. 



Pelecium, Kirby. 



Last joint of the exterior palpi securiform; Iigula short; body ob- 

 long, narrowest before; the four first joints of the anterior tarsi of 

 the males in the form of a reversed triangle, furnished with brushes 

 beneath; the fourth is bifid. 



The species of this and the following subgenus are peculiar 

 to South America(l). 



There, the emargination of the mentum presents a tooth; the 

 mandibles are usually small and moderate in the others. The labrum 

 is entire or but slightly emarginate. 



Some of them approach Pelecium in their exterior palpi, which 

 are also terminated by a larger securiform joint, or one in the form 

 of a reversed triangle. Their head is always small, and the thorax 

 orbicular or trapezoidal. 



Cynthia, Lat. olim Microcephalics, Id. 



The first joints of the anterior tarsi of the males in the form of a 

 reversed triangle and forming the palette: they are provided with 

 a brush underneath, and the fourth is bifid. 



The head and the mandibles are stouter in proportion than in the 

 ensuing subgenus. The exterior palpi are less elongated^ but more 

 compressed at the end. The body is oval, with a trapezoidal thorax 

 wider posteriorly, plane, bordered, and sulcated longitudinal!y(2). 



Panag^eus, Lat. 



The palette of the tarsi peculiar to the males formed of the two 

 first joints only. The head is very small compared to the body, and 

 the eyes globular. The mandibles, maxillae and Iigula are also very 

 small. The thorax is most generally suborbicular(S). 



In the following subgenera, which terminate this section, the ex- 

 terior palpi are filiform; the last joint of the maxillary palpi is 

 almost cylindrical, and that of those attached to the labium, oval or 

 almost like a reversed and elongated cone. The first subgenus, the
