Herm. Miiller, in the Alps, saw Bombus mastrucatus Gerst. 5 getting the nectar 

 by perforation (' Alpenblumen,' p. 249). Schulz also noticed humble-bees stealing 

 in the same way. 



MacLeod saw Bombus variabilis Schmiedehn. 5 in the Pyrenees (Bot. Jaarb. 

 Dodonaea, Ghent, iii, 1891, p. 438); and, in Flanders, 2 humble-bees, an Andrena, 

 a Lepidopterid, Bombus terrester Z. stealing nectar by perforation, Apis and Osmia 

 sucking nectar through the holes thus made (op. cit., vi, 1894, p. 358). H. de Vries 

 noticed a humble-bee, Bombus sylvarum Z. j, skg., in the Netherlands (Ned. Kruidk. 

 Arch., Nijmegen, 2. ser., 2. deel, 1875). 



In Dumfriesshire 3 humble-bees were recorded (Scott-Elliot, ' Flora of Dumfries- 

 shire,' p. 50). 



Von Fricken, at Arnsberg, saw the Curculionid Bruchus pisi Z. as an injurious 

 visitor. 



764. V. sativa L. (Sprengel, 'Entd. Geh.,' p. 357; Heinsius, Bot. Jaarb. 

 Dodonaea, Ghent, iv, 1892, pp. 96-100; Kirchner, 'Neue Beob.,' p. 44, 'Flora v. 

 Stuttgart,' p. 506 ; Schulz, ' Beitrage,' II, p. 21 1 ; Knuth, ' Bloemenbiol. Bijdragen.') 

 In this species the alae are usually violet in colour, the vexillum lilac, and the carina 

 whitish with a blue tip. Kirchner says that the union of the alae with the carina, 

 effected in the usual way, is rendered so firm by the mutual interlocking of the 

 epidermal cells of these petals, that the alae tear when pulled apart. The posterior 

 angles of the carina are drawn out into processes which lie upon the sexual column. 

 There are also finger-shaped alar processes, running backwards parallel to each 

 other. The upper filament is united with the other nine, but two nectar-passages 

 are left at its base. The style is about 2 mm. long, and bears a brush on its upper 

 half, the hairs of which are disposed all round it, and directed obliquely upwards. 

 Externally there is a tuft of longer protective hairs, projecting beyond the stigma.
