2104 Insects. 



yellow, the apex of the latter ferruginous. Thorax shining and punc* 

 tate ; metathorax posteriorly smooth and shining ; the wings subhy- 

 aline, iridescent ; the extreme base and apex of the tibia and all the 

 tarsi pale yellow. Abdomen linear, shining, delicately punctured ; 

 the margins of the segments nigro-piceous ; beneath, the three inter- 

 mediate segments have on each side a tuft of white pubescence. 



This species very closely resembles, in the female sex, that of H. 

 minuta, and is not easily separated from it ; its thorax has, however, 

 a slight aeneous tinge, and its punctures are of different sizes, inter- 

 mixed with very minute punctures, observable under a high power : 

 in minuta the punctures are even and equal in size, and the neuration 

 of the wings stronger than in the present species. The male is readily 

 distinguished from every other species with which I am acquainted : 

 it is remarkable for the little tufts of hair on the segments beneath. I 

 possess four specimens of the female infested by Stylops. 



Sp. 11. Halictus longulus, n. s., Smith. 



Female. — (Length 4 lines). Black; the head and thorax very 

 closely and regularly punctured ; the antennae slightly nigro-piceous 

 towards the apex beneath. Thorax rather coarsely but closely punc- 

 tured, thinly pubescent at the sides, and on the metathorax laterally, 

 which is rotundate ; the tegulae nigro-piceous ; the nervures piceous ; 

 the wings subhyaline ; the legs have an ochraceous pubescence, that 

 on the tarsi beneath is fulvous; the tarsi ferruginous. Abdomen 

 elongate, closely and delicately punctured ; the basal segment very 

 smooth and shining ; the margins of the segments nigro-piceous, re- 

 gularly clothed with a short pale pubescence, most dense at the sides 

 and apex ; the margins of the three intermediate segments depressed. 



This very distinct species was captured at Bonchurch, in the Isle 

 of Wight, in the month of July, by Mr. Charles Bowring, and 

 obligingly presented to me by that gentleman. The form of the ab- 

 domen most resembles that of a male. The species is easily distin- 

 guished from any other with which I am acquainted. I possess two 

 specimens of the female, but do not know the male. 



Sp. 12. Halictus l^vis, St. Fargeau. 

 Melitta Icevis, Kirby. 



Female. — (Length 3 J lines). Black ; the head and thorax closely 

 punctured ; a few scattered fulvous hairs on the face and disk of the
