442 Memoirs on the Coleoptera 



Elytral apices angulate, giving rise to an angulate emargination at the suture; 

 prosternal canal shallow, the posterior lobe very short and broad, evenly 

 arcuate at apex; body generally small in size, with still finer, sparser and 

 feebler sculpture than in the preceding. [Type Baridius acutipennis Say] 



Microcraptus n. subgen. 



3 — Body subcylindric, very small in size, rather strongly sculptured, the elytra 

 evenly rounded behind; prosternal lobe narrower, moderate; tarsi very 

 slender. [Type Pseudobaris cylindricollis Chmp.]. . Craptoleptus n. subgen. 



From specimens sent by Mr. Champion, I surmise that Craptidia 

 will include carinipectus and mutabilis, besides undtdata, and that 

 callosipennis belongs to Microcraptus. 



In the neotropics there are many generic types lying in the 

 "no-man's land" between Pseudobaris and Ampeloglypter, such as 

 Linoma and Linomaspis — the former by way of Heterosternus; but 

 they are generically distinct from either. 



Givenius n. gen. 



The body here is oblong, convex and closely punctured, with 

 sparse and unevenly distributed fine squamules. Beak rather short, 

 moderately thick, cylindric and but just visibly arcuate, with large, 

 bifid and broadly decussate mandibles, and it is separated from the 

 head by only the feeblest impression. Antennae slightly beyond 

 the middle, very moderate, the first funicular joint about as long 

 as the next two, the outer joints rather close and gradually a little 

 broader, the club pubescent, oval, moderate and with very distinctly 

 marked sutures, the basal segment two-fifths the mass. Prosternum 

 flat, the posterior lobe broadly arcuate; coxae separated by nearly 

 their own width, the suture obliterated medially, distinct laterally. 

 Legs rather short, normal, except that the anterior femora are 

 minutely denticulate beneath. Prothorax very briefly although 

 sharply tubulate at apex, the basal lobe short, obtuse and very 

 gradually formed; scutellum slightly free and moderately trans- 

 verse, subquadrate-oval, its surface broadly and deeply impressed. 

 Elytra strongly and sharply grooved, the pygidium small, vertical 

 and transverse. The tarsal claws are in close contact almost 

 throughout, but apparently are not connate. But one species is 

 known as follows: 



Givenius oblongus n. sp. — Form rather broad, oblong and convex, piceous- 

 black, not very shining, the squamules above slender, yellowish, very sparse on 

 the pronotum, herissate in single interstitial lines on the elytra, but condensed 

 toward base of the second interval and in a shorter spot at the base of the third 

 and fourth, also in a small area near, but not at, the base of the fifth; beneath 

 they are small, very fine and sparse, larger on the abdomen and more numerous 

 but not larger or dense on the met-episterna, except posteriorly; beak equal in 

 length to the prothorax, closely punctulate and with a few slender squamules; 

 antennae piceous; prothorax a fourth to nearly third wider than long, the sides
