Euryglossina semiflava n. sp. 
Female. Length about 3 mm. ; head and thorax shining black, with the 
following parts clear pale yellow : mandibles, labrum, entire face to a short distance 
above antennae, narrow bands along inner orbits to tops of eyes, entire cheeks (but 
occiput black), prothorax except middle, tubercles, and anterior part of pleura 
(abruptly limited) ; scape slender, yellow in front, flagellum stout, ferruginous 
beneath, legs pale yellow, hind tibiae brown, their tarsi paler ; abdomen broad, 
dark brown, with a faint purplish tint, first two segments with very slender but 
evident pale bands at apex, terminal segment pale orange, venter yellow. The 
mesothorax is microscopically reticulate, with very few minute punctures. Tegulse 
pallid ; wings hyaline, stigma bordered with fuscous : venation normal for genus ; 
second cubital cell about as high as broad ; first recurrent nervure to first inter - 
cubitus much less than (but more than half) length of intercubitus ; second recurrent 
nervure about half as far from second intercubitus ; three complete discoidal cells ; 
lower section of basal nervure strongly arched. 
Brisbane, Feb. 5, 1916 (H. Hacker). It was taken with Turner ella atomaria 
(Ckll.). It will be readily known bv the yellow face, and sides of thorax with anterior 
half yellow, the rest black. In its markings, this very closely simulates Pachyprosopis 
humeralis Ckll., which is easily distinguished by the shape of the second cubital 
cell. 
Euryglossina hypochroma Cockerell. 
Male. Oxley, Brisbane, Sept. 24, 1914 (H. Hacker). This was described from 
Perth, W.A., but I cannot see that the Brisbane specimen differs at all. 
Euryglossina philoxantha n. sp. 
Male. Similar in appearance to E. perpusilla Ckll., and found with it, but 
easily distinguished by the fact that the face is all yellow up to the level of the 
antennse (in perpusilla are large black wedge-shaped spaces below antennae) : the 
supraclypeal yellow comes to a point between the antenna? ; the lateral marks fill 
the space between clypeus and eye, and reach to the bases of antennae, thence 
narrowing (the inner edge gently convex) to the orbits ; scape stout, yellow in front. 
As in E. perpusilla , the logs and tubercles are yellow, but the prothorax is also yellow 
right across. The abdomen is about the same, but varies to more pallid, with the 
sutures more or less testaceous ; the abdominal venter is honey yellow, and the 
extreme apex dorsaily is red, a feature hardly visible without the microscope. The 
front is microscopically tessellate. Tegulse hyaline, with a yellow spot ; wings clear, 
stigma and nervures dilute sepia ; third discoidal cell complete ; first recurrent to 
first intercubitus not greater than length of intercubitus, but greater than distance 
of second recurrent from end of second cubital cell ; lower section of basal nervure 
strongly arched ; basal nervure to nervulus hardly equal to half length of lower 
section of basal nervure ; anterior and posterior sides of third discoidal cell parallel. 
(E. perpusilla has first recurrent nervure reaching second cubital cell near 
end, the distance less than equal to half of intercubitus ; and second recurrent 
reaching second cubital cell a little more remote from end than first recurrent from 
end of first cubital.) 
The type specimen of E. philoxantha was taken at Brisbane, Oct. 1911 
(H. Hacker) ; others were collected Sept. 12, 1913.
