4. Priocnemis pusillus , Schiodte, Kroy. Tidscli., 4 heft, p. 327. 
Like exaltatus in having the clear round spot at the apex of the 
wings in the $ , hut distinguishable at once by the shape of the anal 
ventral valve of the <$ , which is rounded at the sides, 
and deeply emarginate at the apex, and has the margins 
ciliated with long hairs. The $ may be known by its 
stouter antennae, its less sharply emarginate prothorax pos- Apical seg- 
teriorly, its shorter wings, which have the externo-medial p r .™usiUus , < j 
nervure straight across the base of the first discoidal cell, its shorter, 
more convex, metathorax, and its carinated apical segment beneath. 
Length, 7 — 8 mill. 
5. Andrena htcens, Imhoff, Mitth. schweiz. ent. Gres., ii, p. 67. 
Black, shining, head in both sexes wider than the thorax, face clothed with 
rather long white hairs ; vertex with brownish hairs. Thorax rather sparsely punc- 
tured, clothed with scattered brownish hairs above ; sides thickly clothed with white 
hairs. Wings slightly dusky, with the 1st recurrent nervure springing from nearly 
the centre of the 2nd submarginal cell. Scutellum with only a few very scattered 
punctures, but with a line of punctures down its centre ; metatliorax clothed with 
white hairs. Abdomen ovate, very shining, the basal segments with very fine 
scattered punctures ; the rest more densely punctured at their base, but having the 
extreme apex smooth and impunctate ; 2nd and 3rd segments with a white lateral 
fringe at the apex ; 4th with an entire white apical band ; 5th densely clothed with 
white hairs at the apex in the $ , sparsely so in the £ ; 6tli, in the ? , covered with 
brownish hairs. Legs black, tarsi in the £ entirely testaceous, in the $ described 
from with only the apical joints pale. Scopa in the 9 silvery- white. 
Length, 7 — 9 mill. 
Flying about the flowers, &c., of the heath at Burrow Hill, Chob- 
ham, July and August. 
This species can only be confounded with coitana , and from this, 
the black clypeus and testaceous tarsi at once separate the J, the $ 
are more alike ; but the head in htcens is wider, the face covered with 
white hairs, the thorax more hairy, the scutellum almost impunctate, 
instead of being rugosely punctured all over, as in coitana , the body 
wider at the base, and, therefore, more egg-shaped ; the 4tli segment 
with an entire band of white hairs, and the scopae white, instead of 
brown. It appears from Imhoff that the colour of the legs varies 
greatly, the tibiae being often red.
