284 Mr. E. Meyrick on the classification 



Lederer forms a separate family {Semniidce) for their 

 reception solely on this ground, as well as one {Homa- 

 locliroidce) for the genus Homalochroa, Ld., in which 

 these veins anastomose, but do not separate again, 

 merely an extreme case of the same structure. He 

 describes one vein as cutting through the other, which 

 is essentially erroneous. The second of these families 

 is certainly untenable ; and I see no reason at present 

 for separating any of these genera from the Pyralidida 

 as defined. Persico'ptera differs from Semnia and Eurypta 

 in that veins 8 and 9 rise separately out of 7, not on a 

 common stalk, in the presence of distinct maxillary 

 palpi, in the basal joint of the antennsB not being elon- 

 gate, and other characters. 



Persicoptera pidchrinalis, Gn. 



Endotricha pulchrinalis, Gn., 220, pi. iii., 7 ; Scopula 

 gavisalis, Walk., Suppl., 1475. 



A striking species, somewhat variable in the breadth 

 of the first white fascia. 



Sydney, New South Wales ; Mount Lofty range, South 

 Australia ; and from Tasmania : in September. I have 

 seen, but have not been enabled to examine, the male ; 

 it does not appear to present any singular characters. 



DiPLOPSEUSTIS, n. g. 



Forehead flat, vertical. Ocelli present, concealed. Tongue 

 well developed. Antennae moderate, in male tolerably filiform, 

 evenly ciliated {^), rough-scaled above. Labial palpi moderate or 

 rather long, 2nd joint straight, porrected, with dense tolerably 

 short projecting scales, somewhat thickest in middle, forming a 

 short apical tuft beneath ; terminal joint moderate, slender, fili- 

 form or loosely scaled in middle, obliquely ascending. Maxillary 

 palpi moderate, strongly dilated with dense scales towards apex, 

 obliquely truncate. Abdomen rather long, in male with moderate 

 anal tuft ; valves apparently strong, exserted. Fore wings with 

 veins 4 and 5 stalked, 8 and 9 staUied out of 7. Hind wings 

 broader by one-fourth than fore wings ; 4 and 5 stalked, 7 out of 

 6 near origin, anastomosing moderately with 8. 



Differs from all the other genera of the family known 

 to me in the form of the maxillary palpi, which recall 

 those of Cramhus and Scoparia. In superficial appear- 

 ance the species (especially the second) strongly resemble
