Coleojyferological Notices, V. 583 



at the coxae, which are transversely oval, furnished with a distinct 

 external trochantin, and separated by a little less than their own 

 width, the process gradually narrowed posteriorly, flat, obtusely 

 rounded behind, the sides continued forward along the well de- 

 veloped prosternum to the anterior margin by diverging straight 

 ridges ; apical lobe short, broadly rounded and deflexed. Interme- 

 diate coxae very remote, the mesosternum with a shallow median 

 pit which receives the apex of the prosternal process. Posterior 

 coxae transverse, the upper margin not at all lamelliform, separated 

 by about one-half the meso-coxal interval. Metasternum large, 

 the parapleurae narrow, parallel. Abdomen with five subequal 

 segments, the fifth a little longer, the third and especially the 

 fourth suture strongly flexed posteriorly at the sides. Legs slen- 

 der, moderately long ; tarsi very long, the posterior about as long 

 as the tibi«, with the four basal joints elongate, the fifth slightly 

 longer than the two preceding combined ; claws long, arcuate ; 

 tibial spurs small, remote. 



This interesting genus is founded upon a single example, which 

 I found dead and mutilated some years ago. It should be placed 

 near Dryops, and diff'ers in having raised prosternal lines, in its 

 much longer prosternum and distinct epipleurae ; the latter are dis- 

 tinctly defined but narrow, not quite attaining the elytral apex and 

 gradually slightly wider toward base. 



W. anglistlis n. sp. — Slender, very convex, black, the tarsi paler ; integu- 

 ments shining, sparsely clothed with rather long coarse and decumbent silvery 

 pubescence. Head only slightly visible from above. Prothorax nearly as long 

 as wide, the sides feebly convergent and slightly arcuate from base to apex, 

 the latter broadly arcuate, advanced beyond the greatly deflexed apical angles, 

 which are acute and slightly prominent ; base closely fitted to the elytra, 

 transverse, broadly evenly and feebly bisinuate, not at all emargiiiate at the 

 scutellura, the angles acute but not exposed ; disk very convex, greatly de- 



ivous laterally, transversely biimpressed near the middle befoie the base, 

 not very coarsely but deeply, perforately punctate, the punctures very dense 

 laterally but well separated toward the middle. Scutellum moderate, as long 

 as wide, ogival behind, parallel toward base, the latter truncate. Elytra very 

 slightly inflated behind the middle, rather more than twice as long as wide, 

 nearly one-third wider than the prothorax and scarcely three times as long, 

 acutely triangular behind in apical third ; humeri somewhat broadly rounded 

 to the prothorax ; disk gradually feebly declivous behind, with nine narrow 

 but strong, even, coarsely and approximately punctate striae, the intervals 

 nearly flat, minutely, confusedly, not densely punctulate. Length 3.0 mm. ; 

 width 1.2 mm
