the outer joints gradually wider, compactly joined, the club large, 

 oval, as long as the preceding six joints and subevenly divided by 

 the feeble sutures. The prosternum is even, and separates the 

 coxae by one-half more than their width, being much less remote 

 than in the preceding. Legs short, the intermediate smaller than 

 the posterior, the anterior femora oval and compressed, not dentate, 

 the tarsi small and slender, the last joint rather longer than all the 

 rest, the claws long and arcuate. The prothorax is not in the least 

 tubulate at apex, the basal lobe very small and deeply emarginate, 

 the scutellum small, very free, ob trapezoidal and rounded at apex, 

 and the elytra deeply grooved throughout, the grooves not coarse 

 and exarate apically as in Zalinus, and the pygidium is wholly 

 different, being very large and transversely oval, subvertical in the 

 type. The only known species is the following. 



Anazalinus nanus n. sp. — Cylindric and rather convex, polished, black through- 

 out; beak shining, finely punctate, evenly arcuate and only two-thirds as long 

 as the prothorax, the antenna? piceous; prothorax as long as wide, the subparallel 

 sides very moderately and evenly arcuate, rounding more strongly but gradually 

 anteriad to the extreme apex, which is truncate and slightly more than half as 

 wide as the base; punctures fine and sparse medially, gradually less fine and a 

 little closer laterally, but not longitudinally rugulose, the inferior flanks not 

 rugulose as in the preceding genus but clearly and discretely punctate; elytra a 

 fourth longer than wide, parallel and straight at the sides, rapidly and very 

 obtusely rounded at apex, without trace of humeral swelling, exactly equal in 

 width to the prothorax and not quite one-half longer; grooves deep, a little 

 coarser laterally but not apically; intervals flat, with single series of minute but 

 evident punctures; abdomen very obtuse at apex, distinctly punctured, not 

 sexually modified in the type and with the first suture evident throughout. 

 Length 2.3 mm.; width 0.85 mm. Brazil (Santarem). One specimen. 



The sex of the type is not clearly determinable without dissection, 

 but would appear to be female. 



Myelantia n. gen. 



In this singular genus the body is oblong-oval, much depressed, 

 opaculate and sparsely bristling with erect stiff setae. The beak is 

 nearly straight, not separated by a distinct impression and is 

 parallel and distally flattened, being rather thin in profile, and the 

 mandibles are non-decussate and straight within. The antennae 

 are medial, the scape almost attaining the eye, the first two funicular 

 joints elongate, together not quite as long as all the rest, the outer 

 joints but slightly broader, not very compactly joined and the club 

 small, stout, oval, about as long as the three preceding joints 

 and finely pubescent, with distinct sutures, the basal segment more 

 than half the mass and glabrous at base. The under surface is flat, 

 but broadly impressed along the middle of the prosternum and more
