streak befoi’e the cross-vein in the inner marginal cell, and the 
marginal cell is yellow. The auxiliary vein joining the costa 
almost over, but slightly before, the base of the cross-vein. 
— Antennae about two-fifths longer than the body ; all the 
joints pale brown. Hypostoma pale brown. Palpi pale brown. 
Thorax varying from piceous-castaneous to almost black, in the 
former examples two paler longitudinal stripes are more or less- 
distinctly visible ; these stripes are broad at the collare, gradually 
running to a point posteriorly and disappearing entirely, and 
almost coalescent just before the scutellum ; scutellum brownish- 
ochraceous, sometimes darkei’, sometimes paler. Abdomen rather 
longer than in the ^ j lamellm of the ovipositor yellowish or 
yellowish-brown. Coxse of the fore-legs almost imperceptibly 
tipped with brown. Femora of the hind-legs faded castaneous. 
The fuscous streak in the inner marginal cell is more distinct 
than in the and frequently extends beyond the cross-vein 
towards the apex of the first oblique band.

Oba . — I have only seen one ^ example, which I found fluttering 
on a window ; the ^ forms have been taken by Mr. Masters and 
myself in like situations and in caves. Last April I took two 
small (imperfect) specimens of the 9 from a spider’s web in Mr. 
Macleay’s gai den ; in these the spots on the wings are darkei’. 
They appear to represent a variety of M. decorosa., but an exami- 
nation of Vjetter specimens may prove them to belong to a distinct 
species.
