transverse, not intruding in any way upon the mesosternum. 

 Femora unarmed, the third tarsal joint broad and bilobed, the 

 fourth joint long and the claws closely united toward base. The 

 male has a medio-basal abdominal impression, which sometimes 

 bears a central prominence bristling with slender scales. 



The type of this interesting genus is Baridius quadrimaculatus 

 Boh., of Cuba, and the Porto Rican Baris torquata Oliv., also belongs 

 to Rhaptinus, which is in all probability an essentially Antillean 

 type. It has many bonds of affinity with Trichobaris, although 

 having a very different system of sculpture, vestiture and striation. 



Orthoris Lee. 

 The distinguishing characters of this genus are the slender and 

 often nearly straight beak, rather approximate anterior coxae, 

 oblique pygidium in both sexes, elongate antennal club and absence 

 of the terminal tibial spur. The body is oblong, clothed sparsely 

 with coarse whitish hair, the prothorax small and subcorneal and 

 the tarsal claws are free. More careful observation shows that the 

 species of Orthoris are rather numerous, those now at hand being 

 the following: 



Beak long, very much longer than the head and prothorax 2 



Beak short in both sexes, not or but little longer than the head and 

 prothorax 7 



2 — Beak abruptly tumid dorsally at base. Body oblong, shining, deep 

 black throughout; beak in the female three-sevenths as long as the 

 body, just visibly arcuate, cylindric, strongly sculptured and rather 

 slender, the antennae barely behind the middle, the club cylindric, 

 not quite as long as the funicle; prothorax over a fourth wider than 

 long, the converging sides feebly, evenly arcuate throughout; apex 

 more than half as wide as the base; punctures strong, separated by 

 their own diameters, without median smooth line; elytra oblong, 

 with parallel straight sides, obtusely rounded at apex, two-fifths 

 wider than the prothorax and more than three times as long; striae 

 deep, moderate; intervals flat, with distinct and confused though 

 sparse punctures. Length (9 ) 34 mm.; width 1.3 mm. Wyoming 



(Cheyenne) tumidirostris n. sp. 



Beak not abruptly tumid though sometimes slightly prominent at the 

 extreme base, due to a rapid turn of the surface toward the head. . . 3 



3 — Beak relatively longer, nearly straight 4 



Beak moderately long and evenly, though very feebly, arcuate; descrip- 

 tions drawn from the female 5 



4 — Body larger, deep black, shining, clothed as in crotchi: beak in the 

 female not quite half as long as the body, slender, scarcely visibly
