An ordinary-looking species, but entirely unique by the 
large black spot at end of marginal nervure of hind wing of 
male. In the female this is represented by a much smaller, 
elongated spot. 
Paracolletes nigritulus, sp. n. 
? .—Length about 7 mm. 
Not very robust ; shining black, with scanty white hair; 
black hair on vertex, and a little on thorax above; legs with 
white hair, dark fuscous on outer side of tibie and tarsi; 
abdomen with very scanty pale hair, not forming bands, 
although it is more abundant along hind margins of third 
and fourth segments; hair at apex of abdomen dark fuscous ; 
venter with white hair-bands ; head broad ; clypeus highly 
polished, with large punctures ; supraclypeal area almost 
without punctures ; front shining, with scattered punctures ; 
flagellum obscure reddish beneath ; mesothorax and scutel- 
lum highly polished, with very Sparse exceedingly small 
punctures ; area of metathorax smooth, triangular, with a 
transverse obtuse angulation separating the apical vertical 
face, which is produced ; legs black ; tegule fuscous. Wings 
strongly brownish, the rather narrow stigma and the nervures 
rufo-fuscous ; marginal cell truncate at end; b. n. meeting 
the very oblique t.-m.; second s.m. small, receiving first 
r. n. in middle; third s.m. receiving second r. n. some 
distance from end (the distance about equal to upper side 
of second s.m.). Abdomen shining but microscopically 
sculptured, without evident punctures; hind margins of 
segments rather obscurely pallid. 
Hab. Yallingup, Nov. 1913 (R. E#. Turner; British 
Museum), 2 ?. 
Readily known by the small size, dusky wings, and 
especially the truncate marginal cell. The clypeus is quite 
convex and prominent. 
Paracolletes simillimus, sp. n.

described as metallic; hair of head and thorax quite 
abundant, variously coloured, as follows: long and white on 
face and lower part of front, but with a faint creamy tint, 
contrasting with the pure white of the long and very 
abundant hair on lower part of cheeks; vertex, most of 
front, mesothorax, and scutellums with thin erect dark
