Some Neiv Genera and Species of Hymenoptera. 241 



coarsely reticulated, the sides obliquely striated; the rest of the 

 segment except behind the area closely rugose. Abdomen closely 

 strongly punctured, the punctuation becoming weaker towards the 

 apex ; the third and fourth segments obliquely depressed at the 

 apex ; the apices of the last two smooth. The first recurrent nervure 

 is interstitial. 



This species is closely related to what I take to be H. albidus, Lep. ; 

 the two may be separated thus (the males of both only are known) : — 



Length 7 mm. ; antennae not reaching to tip of thorax, dark 

 coloured below ; metanotal area coarsely reticulated in the 

 middle, the sides stoutly obliquely striated ; the stigma and 

 nervures black, the first recurrent nervure interstitial ; the 



femora and tibiae black lippani. 



Length 5-6 mm. ; antennae reaching beyond tip of thorax ; the 

 fiagellum light testaceous below ; metanotal area closely reticu- 

 lated ; the stigma and nervures pale ; the first recurrent nervure 

 not interstitial ; the femora and tibiae in part yellowish white . . albidus, hey. 



When fresh both species have probably the abdominal segments 

 banded with depressed white pubescence. 



Halictus capicola, sp. nov. 



Black ; the head and thorax thickly covered with long cinereous 

 hair, the depressed bases of the abdominal segments with cinereous 

 pile, the ventral surface covered with long cinereous hair ; the anal 

 rima dark piceous-rufous, the sides and apex of the segment being 

 similarly coloured ; metanotal area strongly irregularly longitudinally 

 striated, its apex more closely finely and less distinctly striated. 

 Wings hyaline, iridescent, the nervures and stigma black. $ . 



Length 8 mm. 



Cape Colony. 



Clypeus strongly punctured to shortly beyond the middle, the 

 punctures large and distinctly separated ; the apex smooth except 

 for a few elongated punctures. Mesonotum closely punctured and 

 with an impressed line on either side of the middle ; the centre of 

 scutellum smooth, the sides sparsely, indistinctly punctured. 

 Abdomen smooth, a transverse, minute furrow on the second and 

 third segments. The apical joints of the tarsi are piceous ; the hair 

 on the under side bright rufous. 



Gen. ANDRENA, Latr. 



Andeena malma, sp. nov. 



Black ; the head with long white, the thorax with rufo-fulvous 

 pubescence, the hair on the pleurae and sternum paler than it is on
