the third, and the remaining joints are gradually a little broader; club 

 small, oval, annulated. The claws are armed with converging teeth, and 

 the thighs are not toothed. 



1. S. fulvus n. sp. 



Above densely clothed with fulvous scales, scutellum, and beneath cin- 

 ereous; beak finely punctured, pubescent at base, narrowed towards the 

 tip. Prothorax wider than long, much narrowed and distinctly constricted 

 in front, bisinuate at base, with the medial angle obtusely rounded. Elytra 

 at base not wider than the prothorax, humeri oblique, obtuse; striae im- 

 pressed, interspaces flat. Beak, antennae and legs ferruginous.

PARAGOGES n. g. 



A curious little species from California constitutes this genus. It has all 

 the essential characters of TycTims, except that the pygidium is somewhat 

 exposed, and the claws are small, simple and approximate. The beak is 

 longer than the prothorax, cylindrical, nearly straight, and rather slender. 

 The antennal grooves descend obliquely below the eyes, which are small, 

 rounded, and coarsely granulated. The funicle is 6-jointed; first and second 

 joints longer, the first being stouter; 3-6 gradually a little broader, some- 

 Avhat rounded; club oval-pointed, pubescent, annulated. Prothorax as long 

 as wide, constricted near the tip, without postocular lobes. Elytra oblong 

 elongate, wider than the prothorax, separately rounded at tip. Angles of 

 second ventral segment prolonged as far as the fourth segment. Legs mod- 

 erate, thighs not toothed; tibiae obliquely truncate at tip, scarcely percep- 

 tibly mucronate; tarsi spongy beneath, third joint broader, bilobed; claws 

 small, simple, not divergent. 



1. P. maculatus n. sp. 



Blackish brown, densely clothed with brownish gray scales, head and 

 middle of prothorax darker; the latter with a few white hairs near the 

 base. Elytra with a large, dark spot extending from the base to the middle, 

 and from the suture to the third stria; this spot is emarginate on the sides, 

 and rounded behind; at one -fourth from the tip is a transverse undulated 

 dark line extending from the fourth stria to the suture; the space between 

 this line and the spot is clothed with nearly white scales; the stria^ are ob- 

 scured by the dense covering of scales. Scutellum covered with pale scales. 

 Antennae nearly black. Length 2 mm.; .08 inch. 



California : two specimens collected at San Diego, by Mr. Crotch. This 

 is a very pretty and easily recognized insect. 



Tribe XII. CIONIXI. 



In this tribe the funicle of the antennae has but five joints; the club is 

 either articulated or annulated. The front coxae are very large and promi- 

 nent, contiguous in some of the genera, separate in others; the claws are 

 simple, approximate, free in Mianis, but connate in the other genera.
