THE ENTOMOLOGIST. 



by the broad keeled base of abdomen. Its nearest ally appears 

 to be the American Paratiphia, which may be known from it by 

 the radial cellule in the female being entirely open at apex, by 

 the first transverse cubital nervure being only obliterated below, 

 by the broad temples, and by the bidentate mandibles. The 

 blue coloration of Cyanotrphia is peculiar, and has not been 

 recorded before with the Tiphids. 



Cyanotiphia ruficauda, sp. nov. 



Black, tinged with blue ; the basal five abdominal segments blue, 

 the apical red ; legs black, densely covered with long white hair, the 

 four anterior calcaria white, the posterior fulvous, the hind tibiae with 

 six stout spines, v/hich become gradually longer aud thinner, the 

 apical beiug considerably longer and thinner than the others. In the 

 centre of metanotum are two straight keels, which converge slightly 

 towards the apex, between them is a more irregular one which does 

 not reach to the apex ; on either side are two slightly curved keels, 

 united at the base, the inner of which does not quite reach to the 

 apex; the space between these keels is irregularly transversely striated. 

 Metapleurfe smooth at the base, the rest somewhat strongly, closely, 

 obliquely striated, the two parts being separated by a furrow. Head, 

 pro- and mesonotum strongly punctured, the punctures clearly separ- 

 ated, the propleurfe strongly, closely, irregularly striated, the meso- 

 pleurfe closely rugosely reticulated. Basal slope and a narrow band 

 on the apex of first abdominal segment smooth, the rest closely dis- 

 tinctly punctured. $ . 



The body is much less densely pilose than iu Paratiphia ; the 

 abdominal segments, too, not bemg fringed with hair. Length, 

 8 mm.

 Museum). 



Tiphia horneana, sp. nov. 



Black, shining, sparsely covered with whitish pubescence ; the 

 four anterior tibiae and tarsi testaceous, the anterior paler than the 

 middle ; palpi pale testaceous, tegulfe testaceous, wings hyaline, the 

 nervures aud stigma black. Flagellum of antennas fuscous. 3- . 

 Length, 5 mm. 



Quop, Sarawak; October (John Hewitt). 



Front strongly punctured, the vertex punctured on the sides and 

 centre. Face aciculated, the clypeus punctured, its centre with an 

 incision, which becomes gradually widened. Mandibles ferruginous at 

 the apex. Basal half of pronotum sparsely weakly punctured, the 

 meso- and scutellum sparsely but distinctly punctured ; the post- 

 scutellum smooth. Metanotum with a strong lateral and a weak 

 central keel, the space between strongly aciculated. Upper half of 

 metapleurffi widely, not very strongly striated, the basal lower half 

 aciculated, the apical weakly striated. Basal two abdominal segments 

 glabrous, the others covered with pale pubescence ; pygidium closely 

 punctured, reddish at the apex. First abscissa of radius roundly
