This is very common on tlie coast on Frankenia ericifolia and 

 possibly on other species of the genus ; the larvae are extremely 

 similar to those of what I must {jxtce Tutt) regard as the very 

 closely allied Jgdistis {Ernestia Tutt) lerlnensis Mill., but, like the 

 perfect insects, considerably smaller. Although variable in size 

 the Tenerife specimens agree better with Zeller's original types 

 from tSicily than with the uniformly larger specimens which I 

 found at Biskra (Algeria). I took and bred many specimens, 

 including a single example at light at Guimar, 1200 ft. above the 

 sea-level, at which alone its food-plant grows. 



13. (1420-1) Agdistis salsolae, sp. n. 



Antennae stone-grey, a dark spot on the basal joint. Palpi 

 very short, the median joint rough, hoary grey ; terminal joint 

 blackish, not projecting beyond the frontal clothing. Head and 

 Thorax hoary stone-grey. Foreioings hoaiy stone-grey, minutely 

 speckled with black, except on the more thinly clothed, slaty grey, 

 triangular fold-space ; the outer third of the costa narrowly white, 

 showing four strong, black, oblique spots, the apex of the wing 

 also black, including the apical cilia ; on the lower edge of the 

 fold-space are two strong, elongate, black spots, preceded by a 

 smaller one at the angle of the fold, and followed by another, more 

 conspicuous, and including the cilia at the tornus, before the base 

 of which it is produced upward along the tei-men ; terminal cilia 

 greyish white, a slender blackish line along their middle. Ex}). 

 al. 16-18 mm. Bindtoings slaty grey, with some black speckling 

 on their lower half ; cilia whitish grey, a slender shade-line along 

 their middle. Abdomen brownish grey, with slender white dorsal 

 and lateral lines. Legs, posterior pair white, thickly sprinkled with 

 greyish fuscous scales — less thickly on the anterior extremities of 

 the joints.

The larva is yellowish brown, varying to giey-brown (jarecisely 

 the colour of dead leaves and stalks of the food-plant) ; it has a 

 o-roup of four small tubercular excrescences on the prothorax, 

 followed by two much larger and more elevated humps on the 

 mesothorax, each tipped with a, black spot ; a much shorter pair, 

 also black-tipped, and i-ather wider apai't on the metathorax ; on
