This genus has the antennae bipectinated nearly to the tips in the males ; the pectinations rather short, tlie 

 palpi short, with the basal joint elongated ; the fore wings triangular, and the hind ones rounded and entire. The 

 caterpillars elongated and slightly hairy, and the pupa enclosed in a slight cucuon. 



Species 1. — Halia Vauaria'. — (Plate LXI., Figs. 9, 10.) — This common insect measures about li inch 

 in expanse. The wings are ashy-white, or pale ashy-brown, with four generally equidistant chocolate-coloured 

 patches on the costa, the third of which is slender and oblique, and the fourth larger and rather square ; 

 adjoining the second is a dark mark like the letter <, thus placed ; this in the female is detached from the 

 second costal spot, which is closer to the first than in the males : beyond this is a row of minute dark dots 

 placed on the veins : the hind wings are nearly immaculate, but with a small dusky spot in the middle. The 

 ground colour of the wings is variable. The caterpillar is brownish or greenish, spotted with black and slightly 

 hairy, and with a pale dorsal line and yellowish lateral ones. It feeds on the garden species of Ribes ; and tiie
