Insects. 1667 



beneath the second segment is generally red, with a black stain in the 

 centre. 



This is a very distinct species from A. Rosae. Mr. Kirby's varieties, 

 4 and 5 are identical with it. Mr. Kirby conjectures they may be 

 distinct, and notices the absence of the minute obtuse tooth at the 

 base of the mandibles of the female : another character will at once 

 separate them, the abdomen of A. Rosae is not punctate, or very 

 delicately so, but that of rubricata is regularly and distinctly so. The 

 antennae of the male of the present species are only about two-thirds 

 the length of those of A. Rosae, and the joints are not bent. The 

 female seldom varies, but the male has sometimes the second segment 

 of the abdomen red ; this variety is however rare. I have met with 

 both sexes abundantly at Highgate, Weybridge, and Hawley, Hants ; 

 it appears about the middle of June. 



I have observed that this bee seldom frequents any flower but that 

 of the wild bryony. 



Sp. 4. Andrena decorata, Smith. 



Female. — (Length 6 — 6j lines). Black, the antennae piceous be- 

 neath ; the face clothed with a pale fulvous pubescence. Thorax 

 coarsely punctured, the sides and beneath have a pale fulvous pubes- 

 cence, sparing on the disk ; the tegulae rufo-piceous ; the nervures tes- 

 taceous ; the floccus very pale fulvous : the scopa fulvous ; all the 

 tarsi rufo-piceous ; the claws ferruginous. Abdomen, the basal seg- 

 ment has a broad red fascia on its apical margin, the second is red 

 laterally, as well as its margin ; the anal fimbria is reddish brown ; 

 beneath, the second segment is red, with a black stain in the centre. 



Male. — (Length 5^ lines). Black, the face has a light brown pu- 

 bescence ; the antennae are as long as the head and thorax, the joints 

 slightly curved; the thorax has a pale fulvous pubescence on the 

 sides, sparing on the disk ; the tegulae rufo-piceous ; the nervures tes- 

 taceous ; the legs rufo-piceous ; all the tarsi pale testaceous ; claws 

 ferruginous. Abdomen lanceolate, the margins of the three basal seg- 

 ments rufo-piceous ; beneath the second segment and apical margin 

 of the third rufo-piceous ; the second has sometimes a dark stain in the 

 centre. 



This species approximates closely to A. Rosae, but is quite distinct; 

 the female differs from that of A. Rosae in having the thorax deeply 

 and closely punctured, and scopa bright fulvous. The male differs 

 from the same sex of A. Rosae, in having the neuration of the wings
