1068 COLEOPTEKA 



cent, basal joint small ; second elongate and gradually widened ; 

 third obconical, much shorter than second ; fourth rather longer 

 than second, broad at base, its apical portion acuminate. Antenna 

 inserted just in front of the eyes, 11-articulate, their basal joints 

 cylindrical, eighth much smaller than the contiguous ones, the three 

 following nearly quadrate. Thorax transverse, finely marginated, 

 sides curvedly narrowed towards the obtuse anterior angles, apex 

 emarginate and bisinuate, posterior angles rectangular, not acute, 

 not overlapping the shoulders, base slightly sinuated ; its surface 

 exhibits a regular slope so that the sides are not in the least ex- 

 planate or thickened. Scutellum distinct, triangular. Elytra cover- 

 ing the pygidium. Front coxa prominent, with only a very narrow 

 linear space between them ; middle pair less prominent, separated 

 by a narrow mesosternal process which is nearly on a level with the 

 coxae ; posterior distinctly yet not widely separated. Prosternum 

 moderately short in front, its sides concave. Mesosternum with an 

 abbreviated frontal carina. Abdomen with five nearly equal seg- 

 ments placed abruptly on a lower plane than the simple, convex 

 metasternum ; the visible portion of the basal segment, however, 

 very short. Epiplewra very broad at base, but becoming quite 

 linear behind, distinctly grooved even near the apices. Tibia with 

 short, slender, apical spurs, not denticulate externally. Tarsi but little 

 dilated, their terminal joint as long as the other four taken together. 

 The structure of the palpi at once distinguishes this genus from 

 Choleva and its allies. Dr. Sharp's genus Catopsilius is a cognate 

 form. 



1909. A. nitidus, n.s. Nitid, bearing but few, almost indis- 

 tinguishable, fine hairs ; castaneous, thorax redder and paler than 

 other parts, legs reddish, tarsi, palpi, and five basal joints of 

 antennae fulvous, remaining joints infuscate. 



Head smooth, narrowed in front of the eyes, with a curved 

 interantennal impression. Thorax gradually sloping, with a row 

 of punctures near the base, only those near the angles well marked. 

 Scutellum smooth. Elytra as wide as thorax at the base, each 

 with about eight series of punctures; the rows in some lights assume 

 the form of striae, but the sutural grooves only are distinct, and even 

 these are obliterated in front. 



Underside pubescent. 



Length, If lines ; breadth, f line. 



Mr. G. Munro found two examples near Clevedon.

(Sharp; Trans. Eoy. Dub. Soc., 1886, p. 383.) 

 Corpus subdepressum, nitidum absque pubescentia. Pcdes 

 graciles, tarsi 5-articulati. Antenna graciles, articulo octavo quam 

 contiguis angustiore, clava gracile, triarticulata. Palpi maxillares 

 articulo ultimo acuminato, praacedente paulo latiore, multo longiore. 

 Prosternum ante coxas sat magnum.
