num ; this widely separates the coxae, which are obliquely conical and 

 decumbent upon the surface separating them, the latter being thus ob- 

 liquely biconcave, the elevated part reduced to a mere cusp point 

 anteriorly, the coxae being subcontiguous at their apices. The sterna 

 of the hind body are very convex, and the mesosternum is abruptly 

 terminated anteriorly by a deep vertical wall. The coxal arcs are 

 nearly as in the subgenus Nephus, but the tarsal claws are long, feebly 

 arcuate, extremely slender and perfectly simple. The epipleurae are 

 extremely narrow, and extend scarcely behind the middle, and the 

 two basal joints of the antennae are large and compressed, the re- 

 mainder very small and slender • the palpi are normally securiform. 

 The eyes are simple and almost entire and are well developed, the 

 clypeus deeply sinuate. The prothorax is as wide at base as the elytra 

 and, in repose, heads rest upon the body in such a way as to conceal 

 all anterior to the mesosternum. The abdomen has six segments as 

 in Scymnus, the first as long as the next three combined. The genus 

 will form a distinct tribe in the neighborhood ofScymnini. 



Zagloba beaumonti, sp. now — Broadly oval, shining, finely, rather sparsely punc- 

 tate and somewhat sparsely clothed with long stiff ashy-yellow hairs, unevenly 

 directed and suberect ; body pale brownish-testaceous in color throughout, 

 the legs more flavate ; sides of the prothorax moderately convergent, very 

 feebly arcuate and distinctly discontinuous with those of the elytra. Length 

 1.5 mm.; width I.I mm. Colombia (Panama) — Mr. J. Beaumont, to whom 

 I am indebted also for the two species described above. 



This species has the metacoxal arcs incomplete and formed as in 

 the subgenus Scymnus, the emargination of the eyes normal and the 

 presternum wide and flat between the coxae, not carinate but tumid or 

 beaded laterally along the acetabula ; the tarsal claws are strongly 

 arcuate, and have a large quadrate internal tooth at base.
