only half the width above, of its base ; the yellow, too, is paler, not 

 so orange-tinted. In P. curvicarinata the yellow mark on the face 

 is twice longer than wide, not square. 



Gen. HALICTUS, Latr. 



HALICTUS ATROVIRIDIS, Sp. nOV. 



Dark green, the apices of the apical three abdominal segments 

 broadly rufo-testaceous ; the four anterior tibiae and tarsi, the base 

 and apex of the hind tibiae and the hind tarsi, except the middle of 

 the metatarsus, rufo-testaceous, the rest of the legs black and 

 covered with white pubescence ; wings hyaline, the costa and stigma 

 testaceous, the nervures black. $ . 



Length 3-5 mm. 



Flagellum of antennae rufo-fulvous, blackish above, apical half of 

 clypeus bronzy coloured. Mandibles testaceous, black at the apex ; 

 the front is brassy tinted ; the punctuation on the front and vertex 

 is fine and close. Metanotal area closely punctured at the apex, the 

 base more strongly reticulated, its apex bordered by a broad, smooth 

 and shining band. Abdomen closely, finely punctured ; the apical 

 segments (perhaps also the basal) with bands of white pubescence 

 on their apices ; the apical segment is entirely rufo-fulvous ; the 

 middle area of a darker rufous colour. The second cubital cellule is 

 of equal width throughout ; the third abscissa of the radius is about 

 one-fourth longer than the second. 



The green colour is not so conspicuous as it is in the common 

 H. jucundus Sm., which is a much larger, much more densely haired 

 species, and its apical segments of the abdomen are not rufo-fulvous. 

 In the larger examples of atroviridis the metanotal area is more 

 distinctly reticulated-striated than it is in the smaller ; in fresh 

 examples the rufous colour on the apices of the abdominal segments 

 is hid by depressed white pubescence ; the basal abdominal segment 

 may be largely tinted with violaceous ; the mandibles may be black.

Gen. CEEAMIUS, Latr. 



Ceramius rufomaculatus, sp. nov. 

 Black, the clypeus, except for a narrow black border on the sides 

 and apex, almost the basal half of the mandibles, a broad transverse 

 mark over the antennae, its upper sides irregularly indented, the
