Rhyphide. 
Rhyphus hooleyi, sp. n. (Fig. 27.) 
Wing 5°2 mm. long; hyaline, mottled with pale brown, 
veins pale. A distinct costo-apical cloud, one in the region 
of the anterior cross-vein, and one about the end of the 
diseal cell. 
H. 456, collected in 1891. Closely allied to the living 
R. punctatus, Fab., with which it agrees in the position of 
the discal and lower cross-veins ; in R. pulchricornis, Brunetti, 
these are nearly equally distant from the base of the discal 
cell, It is also closely similar to R. distinctus, Brunetti.

Rhyphus hooleyi, sp. n. 
An imperfect specimen, In. 17136 (A’Court Smith), with 
reverse I. 9063 (Brodie collection), has the spots darker, but 
seems to belong to the same species. It has a distinct spot 
in the base of the submarginal cell, and the veins at the end 
of the second basal are surrounded by a cloud. There are 
also dark clouds along the lower division of fifth and the sixth 
vein. Experience has shown that the depth of colour and 
distinctness of the spots in such insects differ according 
to the exact conditions of preservation. 
I collected the living R. punctatus, Fb. (det. F. W. 
Edwards), at Gurnet Bay, October 7. 
Bibionide.
