248 THE ENTOMOLOGIST. 



Male. Length 3^ lines. Head and thorax obscure blue- 

 black, in one example faintly green ; the mandibles, clypeus 

 and labrum yellow ; antenn;« fulvous or yellow beneath ; the 

 three apical joints obscurely ferruginous ; the legs yellow, 

 with the coxae, trochanters, and base of the posterior femora 

 more or less rufo-fuscous ; a minute yellow spot beneath the 

 wings ; the claw-joint of the posterior tarsi ferruginous. The 

 antennae a little longer than the thorax. The abdomen of 

 one specimen faintly brassy. The two typical specimens are 

 gummed on card, and have been pressed so strongly that the 

 thorax of one example is crushed, and the other has the 

 abdomen reversed, so that the ventral segments are shown : 

 these are rufo-piceous. 



From this description it will be seen that H. flavipes is 

 identical with " Tumulorum." Kirby describes the wings as 

 " ala) fuscescentes :" this coloration is only apparent; the 

 two pairs are pressed one on the other, and stuck down with 

 gum ; they would be hyaline and iridescent if properly set 

 and cleaned ; the antennae are not longer than in our British 

 specimens hitherto called II. flavipes. 



5. Halictus gramineus. 



Halictus gramineus, Smith, Brit. Bees, p. 36, male, female. 



A very rare species, or certainly a very local one ; I have 

 only once taken it; I found a male and female on a flower 

 on Cove Common, near Blackwater, Hants. This species is 

 entirely of a brassy green colour in both sexes : the female 

 has the tegulae of the wings, the tibiae and tarsi testaceous ; 

 the metathorax dark green ; the abdomen thinly covered 

 with griseous pubescence, and the apical margins of the seg- 

 ments have white marginal bands : the male has the clypeus, 

 mandibles, labrum, tegular, tibiae and tarsi honey-yellow; the 

 antennae are entirely yellow beneath. 



There are several specimens in the British Museum, from 

 Devonshire. 



6. Halictus fasciatus. 



Halictus fasciatus, Nyland. Apis borealis, Nyland. p. 275. 



In my own collection is a female which Ny lander named 

 H. fasciatus : it very closely resembles the same sex of H. 

 Tumulorum, but it has the marginal bands broader and 

 whiter, and, in my specimen, uninterrupted ; the legs are
