1310 COLEOPTEEA 



Head destitute of. distinct punctation. Antenna shorter than 

 the body, basal joint large and stout ; second much smaller, half 

 the length of third ; joints 3-5 equally elongate ; sixth smaller than 

 fifth ; seventh, eighth, and ninth of nearly the same size, each 

 widened apically ; tenth of similar form but longer than the preced- 

 ing one ; eleventh largest, elongate-oval ; the terminal articulations 

 punctate, and bearing more pubescence than the others. Eyes 

 convex and coarsely facetted. Thorax much broader than long, its 

 sides finely marginated and nearly straight, yet gradually narrowed 

 towards the obtuse anterior angles, hind angles acutely rectangular 

 but not prominent ; its surface smooth. Scutellum minute. Elytra 

 with several series of more or less regular punctures, and about mid- 

 way between the middle and apex appearing as if furnished with a 

 plica or fold at the side. Leys stout, the two hind pairs of tibiae 

 curvate, the anterior flattened or concave on the upper face at the 

 extremity ; tarsi stout, basal joint very large and narrowed towards 

 its base, second short, lobes of the third moderate. 



Nos. 1556 and 1557 are nearly twice as large, the former has 

 many small but distinct punctures on the thorax, and the basal 

 articulation of the front tarsus is oblong-oval ; No. 1557 is, on the 

 whole, more nearly related, but its legs are relatively more slender, 

 and the elytral punctation has a tendency to assume a striate ap- 

 pearance. 



. Length, If lines ; breadth, f line. 



Mr. George Munro has been kind enough to present me with 

 the only example he could succeed in finding. 



2302. A. COnvexUHl, u.s. Hemispherical, compact, convex, 

 nude, shining ; black, legs and antennae yellow, terminal joints of 

 these latter darker. 



Head without distinct punctures, reddish in front. Antenna 

 moderately elongate, stout, basal joint thick, second short, third 

 distinctly longer than fourth, joints 4-6 oblong, eighth smaller than 

 the contiguous ones, ninth and tenth broader than the preceding 

 ones, eleventh suboblong. Prothorax transverse, smooth. Scutel- 

 lum distinct, triangular. Elytra with irregular rows of shallow and 

 rather small punctures. Tibice stout and curved ; tarsi stout, 

 shorter than tibiae, basal joint of the anterior oblong, second broad, 

 transverse, third longer than second, bilobed. 



The most convex species yet brought to light, of about the same 

 size as A. minutum, but with shorter and differently-formed antennae ; 

 the tarsi are similar in both species, and both have a distinct 

 scutellum. 



Length, f ; breadth, f line. 



One example, no doubt a female, found amongst vegetable matter 

 on the ground, near Ho wick. 



2303. A. latuluHlj n.s. Convex, broad, shining, black, nude, 

 antennae and legs fulvescent.
