230 Mr. A. G. Butler on the 



Lithosiidae. 



Lithosia gigantea^ Oberth. Referable to the genus Collita 

 of Moore. 



CalUgenia askoldensis^ Obertli. Near to Miltochrista mini- 

 ata, if distirfct. 



ArctiidsB. 



Spilosoma Dverriesii^ Oberth. = 8. punctarium, Cram. 



Spilosoma Janhowskii^ Oberth. Near to Spilarctia lac- 

 teata of India. 



Of S. seriato-punctataj Motsch., which he figures under the 

 name of S. striatopunctata, M. Oberthlir describes specimens 

 as having more or less rose-colour over the secondaries. As 

 we have both sexes with barely a trace of rose-colour both 

 from Yokohama and Tokei, I strongly suspect that these ex- 

 amples with rose-coloured secondaries are referable to my 

 Spilarctia rosacea. The basal black costal dash is cliarac- 

 teristic of a group of allied species ; but its existence on oppo- 

 site sexes of two otherwise dissimilar forms is very apt to 

 mislead collectors, who naturally jump to the conclusion that 

 they have discovered the male and female of one species. 



Liparidse. 



DasycMra virginea, Oberth. 



DasycMra olga^ Obertli. 



DasycMra acronycta^ Oberth. Two species are here con- 

 founded, the male being that sex of I), lunulatay Butl. ; the 

 female, which is new, may retain the name. We have both 

 of these species from Japan in both sexes ; and a mere glance 

 at the two males or females side by side would convince the 

 most prejudiced of their entire distinctness : the male of D. 

 acronycta is considerably smaller than the female ; and the 

 female of D. lunulata is in like manner considerably larger 

 than its own male. 



Leucoma piperita^ Oberth. A species of -4n'aa;a, which we 

 have recently received from Tokei, Japan. 



Lasiocampidae. 



Pyrosis eximia^ Oberth. Near to Podalia dorsimacula. 

 Walk. 



Odonestis asholdensis^ Oberth. Described as a dark variety 

 of 0. potatoria ; but the latter species varies to any extent in 

 this respect ; the colouring, however, appears to resemble that 

 of 0. alhomacidata^ a common Japanese species which cer- 

 tainly is (as M. Oberthiir suggests) distinct from 0. potatoria.
