262 PHYTOPHAGA. [Bruchus. 



pubescence, the black spots being small, obsolete, or even absent. L. 

 3-4 mm. 



On beans ; generally distributed throughout the greater part of England, and often 

 found in profusion ; Dr. Sharp records it as found in the Solway, Forth, and Tay dis- 

 tricts of Scotland, but as imported in beans and not indigenous ; Ireland, near Belfast, 

 and probably widely distributed; the species may have been origiimlly imported, bat 

 it o. curs in the country at a distance from granaries, as well as in warehouses. 



B. affinis, Frol. (flavhiianue, Boh.). In size and general appearance 

 this species strongly resembles the two preceding, but is more closely 

 allied to B. pisi, which it resembles in its shorter thorax, the colour of 

 the pygidium, and the sharp tooth of the posterior femora ; the latter, 

 however, is much shorter than in the last-mentioned species ; from both 

 Ji. pisi and B. rufimanus it may at once be known by the very strong 

 and projecting lateral teeth of the thorax, which cause the sides to 

 appear as if excised before base, and also by the finer sculpture on the 

 thorax and olytra ; the antennae are black with the first four joints red, 

 and at least the anterior tibiae and tarsi, the intermediate tarsi, and the 

 apex of the intermediate femora are red. L. 3-4 mm. 



Imported in beans, and not indigenous; rare; Bearstod near Maidstone and Bark- 

 ing (Power); Sydeuham ; Stretford, near Manchester (Chappell) ; Scotland, Sohvay 

 district. 



B. atomarius, L. (granarius, L. ; seminarius, Sharp's Cat.). Obovate, 

 black, with the thorax and elytra variegated -with white pubescence in 

 scanty spots, with a patch before scutellum and at base of suture ; 

 scutellum white ; antennae black with the first four (rarely three) joints 

 red ; thorax gradually narrowed in front, slightly sinuate at sides, 

 with indistinct lateral teeth, closely punctured, with the base produced 

 in centre into a lobe which is almost emarginate ; elytra with rather 

 strong striae, interstices broad, very closely punctured ; legs black, with 

 the exception of the anterior pair which are usually entirely red, except 

 the tarsi, but occasionally have the femora and even the tibiae more or 

 less infuscate ; posterior femora with a small tooth on under side ; male 

 with the intermediate tibiae armed with a small tooth before apex. L. 

 2^-3 mm. 



On flowers ; not uncommon in some districts, but local ; Caterham, Mickleham, 

 Croydon, Claygate, Cowfold, Horsell, Rusper, Bearsted near Maidstone, Chatham, 

 Faversham, Dartford, Whitstable ; Folkestone ; Hastings ; Faygate, Sussex ; Holm 

 Bush, Brighton ; Portsmouth district ; Weymouth ; Qlanvilles Wootton ; Devon ; 

 Stretford, near Manchester; Ireland, near Waterford (Power), and common near 

 Armagh (Johnson). 



B. luteicornis, 111. Ovate, rather depressed, black variegated 

 with grey or greyish-white pubescence, which is distributed in small 

 patches, a spot at base of thorax and another at base of suture of elytra 

 being most conspicuous ; scutellum also covered with pubescence ; in 

 fresh specimens the elytra have a double greyish interrupted line on the
