fuscous. Head and Thorax dull white. Forewings dull white, minutely sprinkled 

 and sparsely spotted with pale brownish fuscous ; the ill-defined spots are formed 

 by aggregation of the otherwise scattered pale fuscous scales and are, first a small 

 streak at the base of the costa, reduplicated below and beyond ; secondly a sub- 

 costal spot at one third, then a spot at the end of the cell, preceded by one a little 

 beyond the middle of the fold, with another, subcostal, a little before the apex ; 

 there are one or two marginal dots before the dirty white cilia which are also 

 slightly dusted. Exp. al., II — 12 mm. Hindwitifjs and cilia brownish grey. Ah- 

 domen brownish grey. Legs dirty white.

Although in general appearance this species does not look dis- 

 tinct and cannot easily be separated by description from cedestiella, 

 7i., and sparsella, do Joann , it is more robust than the former and 

 lacks the median fascia, and it is a more chalky looking species with 

 greyer markings than the latter. It is really quite distinct when 

 series of each are compared,

Antennae hoary grey. Palpi hoary white, dusted with greyish fuscous. Head 



hoary grey. Thorax hoary whitish, dusted with greyish fuscous. Forewings hoary 



greyish white, profusely speckled with greyish fuscous throughout, this is for the 



most part evenly distributed, but a line along the centre of the wing nppears (o be 



somewhat less obscured by the dark speckling, while a reduplicated transverse spot at 



the end of the cell is slightly indicated, a jjlical and another discal spot scarcely to 



be detected, their possible position being shown only by a slight increase of the 



dark dusting in each place ; cilia hoary grey. Fxp. al., 11 — 13 mm. Eindwings

 Salahin, 8- 23. IV. 1904, 17.V.1903. Thirty-one specimens. 



Flies low in the early morning on rather bare ground. It has 

 much the appearance of Eremica saharae, but is of a greyer colour 

 and without any indication of transverse markings, its shading, if 

 any, being always longitudinal. 



3043 : 3. — Symmoca molitoh, sp. n. 



Antennae pale brownish, hoary whitish towards the base. Talpi hoary whitish, 

 the median joint shaded with black below towards its apex, the terminal with a 

 black annulation before its apex. Head and Thorax hoary white, the latter with a 

 black spot posteriorly. Forewings rather narrow, elongate, tapering to an obtusely 

 rounded apex ; hoai-y white, profusely sprinkled with black atoms which have a 

 tendency to run in lines, especially along the upper edge of the cell, and from the
