The black line spotted with white running along near the inner edge 

 of the wing-cases is very noticeable in the above-named species, 

 B. rKfituanus, when the specimens are fresh ; but these are often so

much injured that they appear almost black, from the hair being 

 rubbed oft". 



This species has long been naturalized (even if not originally one 

 of our native insects) in this country, and is to be found in Central and 

 Southern Europe, also in Syria, Egypt, and the whole of Northern 

 Africa. It has been noted by the late Dr. C. V. Eiley that, "although 

 this species has frequently been brought to the United States, it has 

 probably not obtained permanent footing there."" Also, at p. 165, 

 vol. v., of same work, it is mentioned that this species, B. rufimamis, 

 Bohm., has been bred from Pea pods imported from Switzerland, and 

 from Peas distributed by the U.S.A. Department of Agriculture in 

 1890. But though elsewhere, and as matter of curiosity, it may have 

 been recorded as present in a very few of the LeguminoscB besides 

 Beans, with us it is, I believe, solely troublesome as infesting Broad 

 Bean seed. 



B. pisorum, Linn. (= pisi, Linn.), figs. 9, 10, p. 21; fig. 4, above. 

 Length 4-5 millimetres. One of the largest of the species under con- 

 sideration ; oblong ovate, black, variegated with various shades of 

 greyish down ; shanks and feet of the foremost legs, and feet of the 

 middle pair red. Thorax transverse, narrowed in front. Scutellum 

 (small spot at the middle of the base of the thorax) whitish, with a 

 minute white spot before it. Wing-cases with spots or marks of white 

 down — these sometimes arranged as a wavy baud, about four in 

 number, across each wing-case, wnth one spot on each nearer the base. 

 Pygidiwn thickly clothed with whitish down, showing two large bare black 

 roundish spots. For this, see fig. 10, p. 21, and fig. 4, above ; it is a 

 very important characteristic distinction.
