Where the caterpillars are attacking lucerne, closely feeding it off with sheep would 
probably prove effective. Large numbers of the larvae would he either eaten or trampled 
upon, while at the same time the ley would benefit from the droppings of the animals. 
disease that appeared to be of a bacterial nature cleared off swarms of the caterpillars 
that were feeding on lucerne at the Government Experimental Farm at Ilalfaya in 1906.

The Green Molokhia Worm 
Gonitis involuta, Walk. 
Plate XXVII., fig. 2 
The larva of this moth was frequently noticed during 1900 feeding on jute, which 
is grown by the natives as a potherb, and known to them as molokhia. 
Larva .—A bright green caterpillar about 30 mm. in length. 
Head, green with a faint brown median stripe. First segment, dark green with two 
white dorso-lateral spots. A yellow transverse dorsal bar on the eleventh segment. Two 
pale longitudinal lines originate in the white spots on the first segment and extend the

brown with black spots. 
Ilind-wings, uniform dusky brown with a pale fringe. 
In some specimens there are two black sj)ots on the fore-wing. 
Betnedial treatment .—Where the caterpillars are very numerous, hand-picking should 
be resorted to. 
The K e d Molokhia Worm 
Tarache tropica 
Plate XXVII., fig. 8 
This caterpillar was found attacking molokhia in company with Gonitis involuta. 
Larva .—A reddish-green caterpillar 20-25 mm. in length. 
Head, chestnut-brown. Legs, black. Body, greenish. Fifth to eighth segments 
tinged with red, remaining segments tinged with yellow. Darker median dorsal line edged 
with black. White longitudinal lateral lines level with the spiracles. Many white and 
yellowish spots and black tubercles, some of which terminate in a hair. 
Adult (fig. 8).—A green-and-white moth 7-8 mm. in length and with a wing expanse 
of 15-20 mm. 
Female. —Thorax, olive green edged with white laterally and anteriorly. Fore-wing,

dark rings. Fringe, green with two white patches. Hind-wings, smoky grey.
