Intermediate between Gelechia, lib., and Acompsia, Hb., differing 

 from the latter in vein G of the forewiugs arising from the stem of 

 7+8 in which it also differs from Busck's description of Gelechia, as 

 also in the smooth median joint of the palpi. The neuration of 

 Gelechia as given by Meyrick, " Forewings : G seldom out of 7 near 

 base," would include this form, and his description of the palpi, 

 '* thickened with more or less rough scales beneath," might be strained 

 so as not to exclude Leohatus, but as by his tabulation it would go to 

 Acompsia, Hb. {= Recurvaria, llw., Meyr.), the erection of a genus 

 iov fagoniae seems justified. 



2509 : 1. — Leobatus fagoniae, sp. n. 

 Antennae black. Palpi pale brownish oclireous,. the median joint smoothly 

 clothed, with two blackish spots externally ; terminal joint at least as long as the 

 median, with two black aimulations. Head pale buff. Thorax blackish, the 

 tegulae tipped with buff. Forewings buff, with a slight rosy tinge, the extreme 

 base and the dorsum to two-thirds suffused with black, the outer half of the cell 

 also strongly suffused with black which is connected with the dorsal shade, except 

 where a spot of the ground-colour remains in the fold, this discal shade is further 

 connected to the costa before and beyond the middle, thus the whole basal two- 

 thirds of the wing are overclouded with black, except a patcli on the middle of the 

 costa, another patch toward its base extending to the fold, and a spot in the fold a 

 little before the middle ; the outer edge of the black shading is somewhat clearly 

 defined by a band of the pale buff ground-colour, which is again suffused towards 

 the apex with pale bronzy brown, the black reappearing along the tcrmen and in 

 scattered dots through the smoky brownish ochreous cilia. Exp. al., 15 mm. 

 Hindwings broader than the forewings, slightly indented below the apex ; pale 

 grey, shining ; cilia pale brownish cinereous. Abdomen ochreous, shaded across the 

 middle with smoky black. Legs ochreous, the tarsal joints faintly spotted with 

 blackish.

 22. Ill, Larva Fagonia (jlutinosa aud sinaica, II, excl. 1-1-20.IV.1903 ; 

 7-12.III.1901. Twelve specimens. 



I found the larva of this species by no means unfrequeut on 

 Fagonia glutinosa and sinaica, spinning loose webs along the trailing 

 stems aud upon the ground beneath or the rocks behind them. It 

 occurs on the plains to the west of Biskra and on the hills behind 

 Hammam-es-Salahin, also abundantly on the smaller hills beyond the 

 Biskra race-course, and near the French cemetery.
