British Hymenoptera. 247 



Hab. Very common in spring, and generally distri- 

 buted. Could only be confounded with thoracica, from 

 which the pale pubescence of the head and under side, 

 and femora, &c., at once distinguish it. 



14. Andrena fulva, Schrank. 



Schrank., Enum. Ins. Austr., p. 400 ; Smith, Cat. 

 Brit. Hym., 2nd ed., p. 38. 



Face of S' with white hairs, of ? with black. <? man- 

 dibles very long and curved, toothed outwardly at the 

 base. Thorax densely and abdomen more sparingly 

 clothed with bright brown hairs. Posterior tarsi and 

 extreme apex of tibiae pale. $ entirely clothed with 

 bright red hairs above ; beneath and legs with black 

 hairs. Wings clear in both sexes, recurrent nervure 

 received near the apex of the 2nd submarginal cell. 



$ . Black ; head wide ; face clothed with white hairs, 

 mixed with pale brown hairs and a few black ones, 

 vertex with pale brown hairs. Antennae reaching to the 

 scutellum. Mandibles very long, pointed, and curved, 

 base outwardly with a sharp tooth, narrow at its base. 

 Thorax densely clothed with bright brown hairs ; basal 

 area of metathorax very finely rugose. Abdomen 

 elongate-oval, slightly shining, finely punctured, except 

 towards the apices of the segments ; clothed with golden 

 brown hairs, which are longest on the 1st and 2nd 

 segments ; beneath sparsely punctured, apex of each 

 segment with a fringe of long golden brown hairs, apical 

 ventral segment truncate and testaceous at its apex. 

 Legs clothed with golden brown hairs, posterior tarsi 

 and the apical joints of the anterior and intermediate 

 tarsi testaceous. 



? . Head densely clothed with black hairs. Thorax 

 with bright, darkred hairs above, black beneath. Abdomen 

 above rather paler as to its pubescence than the thorax, 

 but very densely clothed with it ; the apex of the 5th and 

 the 6th segments clothed with black hairs ; under side 

 and legs clothed with black hairs ; calcaria and apices of 

 the tarsi pale testaceous. Length 12 — 14 mm. 



Hab. Common in many places in the London district 

 and elsewhere, but apparently local. The ? is unlike 

 every other British bee ; the ^ resembles Trivwierana as 

 much as any species, but the white hairs of the face and 

 the tooth on the base of the mandibles will separate it 

 at once.
