46 Mr. T. D. A. Cockerell—Descriptions and 
Paracolletes abnormis, sp. 0. 
¢ .—Length about 6 mm. 
Rather slender ; black, with dull white hair, the face and 
front densely covered with long shining white hair, com- 
pletely hiding the surface up to level of anterior ocellus ; 
the hair on front is abruptly limited above, and the portion of 
the vertex carrying the large ocelli is flattened and depressed, 
so as to appear part of the front, forming a basin bounded 
above by a shining rim on each side, the vertex forming the 
upper margin of the head narrow (antero-posteriorly) and 
rounded ; cheeks smali ; mandibles with a dark red mark 
in middle; scape black; flagellum pale ferruginous beneath 
(including apical joint), dusky red above ; mesothorax 
shining, with sparse small punctures; area of metathorax 
semilunar, with very indistinct ruge; legs black, with the 
knees, aritexior tibiz in front, the other tibize at apex, and 
all the tarsi, clear ferruginous ; tarsal joints 2 to 4 broad- 
triangular, giving the tarsi in this region an unusual 
thickened appearance; tegule pale testaceous. Wings 
hyaline, nervures and the rather large stigma; b.n. arched, 
the lower part nearly vertical, almost reaching t.-m., which 
is hardly at all oblique ; only two s.m. cells, the very long 
second receiving the recurrent nervures near base and apex ; 
on one side can be seen above a minute stump representing 
the lost second t.-c., it is halfway between the first t.-c. 
and the insertion of the third on the marginal ecll ; mar- 
ginal cell long, rather obliquely truncate at apex. Abdomen 
shining, with extremely fine punctures, no hair-bands, but 
the surface thinly hairy; fifth ventral segment with a ‘long 
dense fringe of white hair, longest at sides. 
Hab. Alexandria, N. Australia (W. Stalker; British 
Museum). 1 
P. abnormis is a very peculiar species, which, from having 
only two s.m. cells, would be associated with P. vitrifrons 
(Sm.) and Andrenopsis flavorufus, Ckll., but it is not closely 
related to either of these *. 
Paracolletes nitidulus, sp. n. 
? (Type).—Length 95-10 mm. 
Shining black, not very robust, with thin white hair ; 
vertex with long black hair ; mesothorax and scutellum with 
* Since writing the above, I find that I overlooked a second specimen 
of P. abnormis from the same locality. This has three submarginal 
cells in both anterior wings ; the second s.m. small, receiv ing the first 
r. ou. about the middle.
