wider than the prothorax, thou obtusely rounded ; smooth with a deep 

 sutural stria and two raarjijinal striae which are abbreviated in front, 

 the inner one being fainter and shorter. Legs very stout, front tibise 

 three-toothed, not serrate ; middle and hind tibiae thick, with the 

 transverse crest and apical margin well developed ; spurs of middle 

 tibiae long, of the hind pair short, broad and obtuse, the outer one 

 being the larger. Tarsi, front as long as the tibiae, slender, joints 1 — i 

 equal ; middle shorter than the tibiae, joints 1 — 4 decreasing a little in 

 length; h^nd pair only half the length of the tibiae, stouter, joints 1 

 — 4 slightly decreasing in length; claws slender, simple. 



I*. lne%'is. — Chestnut-brown, shining; head with a frontal tubercle an(i 

 transverse broad impression; prothorax and elytra smooth, the latter with a 

 deep sutural and two marginal striae; margins of body, under surface and leg* 

 clothed with long erect hairs. Length .26 inch; 6.5 mm. 



One specimen, Sta. Barbara, Califjrnia; Mr. Crotch. Remarkably 

 different from all the species of the tribe thus far described by the 

 absence of the elytral rows of punctures.

 I*, liigubris. — Black, with a feeble metallic tinge; prothorax sparsely 

 punctured, more finely ami densely towards the sides, which are rounded 

 narrowed in front of the middle, but only slightly so towards the base, angles 

 rectangular, slightly prominent; elytra dull, finely alutaceous, with scarcely 

 perceptible traces of distant rows of punctures. Length .7 — .9 inch; 17.8 — 

 22.7 mm. 



%. — With the front tarsi thickened, the inner claw dilated at base, and the 

 club of the antennoe longer. 



Arizoiia; Mr. C. V. lliley; also in the collection of Mr. Ulke. 

 Related to F. Lucae, but quite different by the nearly black color, the 

 more finely punctured prothorax, which is less rounded on the sides, 

 and less narrowed towards the base, and finally by the rows of punc- 

 tures on the elytra being almost obliterated. The head is alike in 

 both species, densely punctured, with the clypeus narrowly margined, 

 and at the tip subtruncute, a little more distinctly so in the present 

 species.

 C. retractns. — Browmsli-black, not shining; prothorax wider than long, 

 coarsely punctured, narrowed in front, broadly rounded on the sides, foveate 

 inside of the front angles, fovese not extending to the apical margin, hind an- 

 gles suddenly and strongly retracted, acute, surrounded by a deep grooTe; 

 elytra flattened, with the usual sculpture of large shallow punctures, not 

 closely placed. Length .44 inch; 11 mm.
