200 [February, 



Mr. J. B. Bridginan first called my attention to this species, and 

 sent me a specimen to examine ; I found a similar one amongst my 

 specimens of unighimis taken at Littlehampton in July, 1S73, and I 

 have little doubt that they were referable to the above species. 



Halictus PAUxiLLrs, Schenck. 



? in general appearance and size resembling minutus, but differing in the less 

 closely punctured and shorter mesothorax, and the more definitely truncate meta- 

 thorax, also in having the 1st segment of the body very shining and almost impunc- 

 tate, such punctures as there are being so fine and scattered as to be scarcely 

 observable ; besides these characters there is a faint indication of a small white 

 pubescent spot at the base of the 2nd segment, and all the segments are widely pale 

 at the apex, the body is also of a slightly more regularly oval shape. 



I have taken 5 a of this species at Chobham, and have others from 

 Charlwood, Surrey. Dr. Capron has also taken it at Shere, near Guild- 

 ford, and had himself separated it as a species new to him. I do not 

 know the ^ . 



H. LONGiCEPS, n. sp. 



Allied to minutus, but at once distinguishable by its long narrow face, which is 

 considerably longer than wide, the mesothorax is also much more coarsely punctured, 

 and the puncturing of the body is also coarser. The $ which I refer to this 

 species has exactly the same shaped face as the $ , and the puncturing of the 

 thorax and body also corresponds ; the head is thickly covered with grey hairs, and 

 the clypeus is whitish at the apex ; the antennae, when the head is laid back, extend 

 beyond the scutellum, and are fulvous beneath ; the body is very closely punctured, 

 the tarsi pale, more or less brownish towards the apex. 



$ not uncommon at the blossoms of the heath at Chobham, in 

 June. I have specimens also from AVandsworth, Reigate, and Has- 

 tings. ^ from Reigate and Southwold. 



H. BREVICEPS, n. sp. 



$ . Another of the minutus group, but very distinct from that species or longiceps. 

 It has a shorter, rounder head than minutus, with a shorter, wider clypeus, the 

 puncturing of the thorax is much coarser, the body and wings are shorter, and the 

 nervures of the latter paler ; the basal segment of the body is very smooth and 

 shining at the base, punctured at the apex ; the whole insect has a peculiarly thick 

 compact form. 



I have taken this species at Chobham and Hayling Island, but 

 have not met with the (J . 



H. PUNCTicoLLis, n. sp. 



Allied to viUc^ulus, and with the same shining surface to the thorax, but with
