102 MR. M. JACOBY ON THE [Feb. I, 



nearly square-shaped and smooth ; labrum piceous. Antennae nearly 

 as loiig as the body, testaceous, the third and following joints elon- 

 gate, nearly equal in length and much longer than the second joint. 

 Thorax more than twice as broad as long, the sides rounded at the 

 middle, narrowed near the anterior angles, the latter slightly pro- 

 minent ; the surface shining, scarcely visibly punctured near the side, 

 with a short anterior and posterior transverse groove and a small 

 anterior fovea as well as an obsolete oblique posterior lateral depres- 

 sion. Scutellum obscure fulvous. Elytra closely pubescent, very 

 finely ruoose-punctate, the basal margin and the sides to below the 

 middle obscure piceous or fuscous, the rest of the surface very ob- 

 scure fulvous. Legs and underside testaceous ; the claws indistinctly 

 bifid. 



SpHjEropleura (gen. nov. Halticinorum). 



Body strongly rounded and convex. Antennae filiform, the first 

 joint slender, the second and following joints nearly equal and shorter. 

 Thorax suhhemispherical, without dejjression. Elytra puuctate- 

 striate, their epipleurfe very broad and concave, continued to below the 

 middle ; the posterior femora strongly dilated ; the four posterior 

 tibiae mucronate ; the first joint of the posterior tarsi as long as the 

 two following joints united ; claws appendiculate. Prosternum nar- 

 row, deeply longitudinally channelled. Mesosternum deeply emargi- 

 nate at its apex. Anterior coxal cavities closed. 



Sphceropleitra agrees in shape, which resembles that of a species 

 of Coccinella, with Sphcerophyma, Baly, Argopistes, Motsch., and 

 Homelea, Jac. It differs from the first-named genus in the much 

 less strongly dilated posterior femora, the longer and not dilated 

 tibiae, and the smaller eyes, also in the want of a thoracic median 

 lobe. From Argopistes this genus may be separated by the filiform 

 antennae and the punctate-striate elytra ; and from Homelea by the 

 much more strongly incrassate posterior femora, the latter in i/o?ne/e« 

 being only about one half thicker than the rest of the thighs, and 

 the mesosternum strongly transverse and of different shape, and the 

 elytra irregularly punctured. 



Sph.eropleura tricostata, sp. nov. 



Piceous below ; antennas, tibia3, and tarsi testaceous ; head and 

 thorax impunctate, black ; elytra finely punctate-striate. 



$ . Each elytron with three short but distinct costae near the apex. 



Var. Elytra fulvous. 



Length 1| line. 



Head entirely impunctate ; the frontal tubercles very small and 

 indistinct; labrum fulvous. Antennae about half the length of the 

 body, testaceous, the terminal joint fuscous. Thorax suhhemi- 

 spherical, more than three times as broad as long, the sides straight, 

 the angles not produced but distinct. Elytra wider at the base than 

 the thorax, very convex and roimded, the punctuation very fine at 

 the middle of the disk, much more distinct towards the sides ; of the 

 three costae placed near the apex in the female, the first is shorter
