1900] BEAN AND PEA-SEED BEETLES. 23 



Thus we have (from an entomological point of view) a most 

 satisfactorily complete observation, — the cargo of Barley, containing 

 amongst it Beans and wild Peas, was forwarded from Smyrna by the 

 rapid transmission of a steamer to Hull, and attention was drawn at 

 Newark-on-Trent by the numbers of Bruchi straying about in the 

 Barley to there being something amiss ; examination showed infesta- 

 tion to be present in the Peas and Beans, and in the latter (of which 

 plentiful specimens were forwarded me) I found Bruchi just ready to 

 come out. 



On examination of the specimens sent me I found presence of four 

 species, of which two were of our long linown kinds, namely, Bruchus 

 rufimanus, Bohm.,- which infests Broad Bean seed, and B. pisi, L. 

 ( = pisorum, L.), which is found in Peas. Besides these were two 

 species with which I was wiiolly unacquainted, and I was much obliged 

 to Mr. Oliver E. Janson, F.E.S., of 44, Great Russell Street, London, 

 W.C., for identifying them for me as, respectively, B. brachialis, 

 Fahrs., and B. tristis, Bohm. Besides the above kinds, a single speci- 

 men of yet another species was found by Mr. Janson in the small 

 consignment, which proved to be of B. nijipes, Herbst. 



The figures of the first two are given at p. 21 ; and also of all the 

 five species placed near together for convenience of comparison of the 

 characteristic markings, at pp. 24, 25. 



The description of the main distinctions of the beetles, also the 

 countries where they are chiefly to be found, may be shortly given as 

 follows. 



B. riifitnamis, Bohm. (Broad Bean-seed Beetle), 1 and 2, p. 21 ; 

 5, p. 24. — Length 3-4 millimetres f ; shape oval ; on the whole much 

 resembling ■pisorum (description of which see following), but less 

 densely clothed with short brown hairs. The wing-cases are variously 

 sprinkled and marked with white and greyish or reddish hairs ; and 

 with a longitudinal black line interrupted by a few white lines near 

 the inner edge of each. Wings ample. 



Tlie pygidium (that is, the exposed terminal part of the abdomen) 

 clothed ivith grey pubescence, occasionally, or in some lights showing two 

 dark spots. Thighs of the foremost pair of legs and four lowest joints 

 of the antennae rusty or red. 



The markings, or absence of marking, on the grey down of the 

 extremity of the abdomen is one characteristic by which the five kinds 

 of Bruchus under consideration may be distinguished from each other. 



* The B. granarius, L., of Curtis and many writers. 



f Twenty-five millimetres are equivalent to one inch, so also are twelve lines ; 

 consequently, for general purposes, two millimetres may be considered as nearly 

 equivalent to one line. But for scientific purposes it may be desirable to give the 

 length to a fraction, therefore I note the measure in millimetres as above.
