middle on the underside; this tooth lias been overlooked by Schonlierr, 

 while Lacordaire describes the thighs as unarmed. 



2. P. pictus, n. sp. 



Testaceous, clothed with pale-yellowish pubescence ; head and beak 

 dusky. Elytra with a large rounded common dusky spot extending from 

 the base to the middle, paler within ; and a dusky oblique band, more or 

 less interrupted on the seventh interspace, which attains the suture about 

 one-fourth from the tip ; strioe punctured, less deep than in P. scutellaris. 

 Thighs armed with a small acute tooth ; claws appendiculate. Length 

 2.5 mm. ; .10 inch. 



Georgia; one specimen. The large common spot of the elytra is dark 

 only at the edge, in the middle it is nearly as pale as the ground color. A 

 manuscript drawing by my father named Arliynchus tomentosus \ Dey 

 Cat. resembles this species. 



Tribe XL tychiibti. 



In this tribe a form of body is resumed, which resembles that of the 

 Erirhinini. The claws, however, are not simple, but appendiculate or 

 toothed, and the second, third and fourth ventral sutures are not straight, 

 but strongly angulated at the sides. The prolongation backwards of the 

 side angles of the second segment is in some genera carried to such an 

 extent that the points reach the fourth segment, and the sides of the third 

 segment are thus entirely covered. The pygidium is usually exposed, 

 by the tips of the elytra being separately rounded, but in TycMus they are 

 conjointly rounded, and the pygidium is covered. This character, as in 

 Antlionomini, possesses, therefore, but little value. The ventral segments 

 are less unequal than in Erirhinini. 



The other characters are those common to the preceding tribes ; Beak 

 long and usually slender; antennte inserted far from the tip; antennal 

 grooves directed sometimes against the eyes, sometimes below them. 

 The eyes are rounded or nearly so, not finely granulated. The funicle 

 of the antennae is 6- or 7-joiuted, and the club entirely pubescent and 

 annulated. The prothorax has no postocular lobes; the prosternum is short, 

 not strongly emarginate in front, and the coxae are contiguous. Tlie side 

 pieces of the mesothorax are diagonally divided, and the epimera do not 

 largely attain the base of the prothorax. The metasternuni is long, and the 

 side pieces are narrow, or moderately wide, dilated in front. Tibi« feebly 

 or strongly mucronate; articular surface prolonged on the outer face, ao as 

 to become oblique. 



Our genera with three exceptions have not been described : 



Angles of second ventral segment not extending to the fourth 2. 



Angles of second ventral segment extending to the fourth S.
