$ 9 . — Size moderate ; form compact ; $ antennae with the edges of the 

 joints relieved and furnished with short cilial tufts ; ? abdomen pointed with 

 extruded oviduct ; eyes hairy. Dark colored, fore wings uniformly dark with 

 faded ornamentation. Fuscous with pearly mottlings caused by a sparse 

 admixture of white scales over the thorax and primaries. Transverse lines 

 perceivable by pale centerings. Basal half-line twice waved. T. a. line 

 perpendicular, thrice waved. The wing is more or less tinged with rufous 

 over the median space on which the ordinary spots are with difficulty to 

 be perceived ; they are dark-circled, picked out by pale scales, concolorous. 

 Above the reniform the t. p. line is incepted on costa by pale scales. The 

 line is of the usual shape, slightly inwardly arcuate below median nervure, 

 slightly lunulate. Three pale ante-apical costal dots. Terminal space nar

 under some other generic title, by Mr. Walker in the British 

 Museum Lists. It may be remarked here that a condemnation of 

 Mr. Walker for an occasional erroneous determination in the
