Peronea Hastiana, shewing the innumerable varieties, and the tendency of these 

 Tarieties to connect. As they were obtained from collected larvae it was impossible 

 to state to what extent the variation might be hereditary. He also exhibited, on 

 belialf of Mr. Sidney Webb, of Dover, an interesting series of Cidaria suffumata, 

 with especial regard to the progeny of particular females, the parent, and the produce 

 of the eggs laid by her being carefully separated. Mr. Vaughan also read notes on 

 the subject communicated by Mr. Webb, and Messrs. Weir, Waterhouse, Stainton, 

 Sharp, Distant, and others, took part in the discussion that ensued. 



Mr. A. Or. Butler communicated a paper on " New genera and species of 

 Heterocerous Lepidoptera from the Australian region," in which 21 new genei'a and

THE SCYDM^NIB^ OF JAPAN. 

 BY D. SHARP, M.B., F.Z.S. 



Twelve years ago I described, in the Transactions of the Entomo- 

 logical Society of London, five species of this Family. These were the 

 first ScydmcenidoB known from Japan, and no others have yet been 

 added to them. I am now enabled to bring the number of species up 

 to fifteen, all of which have been discovered by Mr. George Lewis. 

 Nothing is yet known of the 8cyd7ncBnid(S of China, and as the 

 Japanese members of the Family have but little close relationship to 

 those of Europe, it appears at present that all are peculiar to the 

 islands. When I wrote twelve years ago the genera were not in a 

 very well defined condition, but since then they have been greatly im- 

 proved by the labours of Reitter, and Euconnus may be accepted as 

 distinct, as well as Eiimicrus, although Schaufuss (who has been one of 

 the most extensive describers of this Family) is still of a contrary 

 opinion as to Euconnus. 



1. Euconnus impab, sp. n. 



Convexus, rufescens, nitidus, thorace parum hirto,capite elytrisque nudis; antennis 

 sub-ffracilibus, clava quadriarticulata ; thorace suh-oblongo, haud impresso ; elytris 

 inter suturam et hameriim impressione subtile longitudinaJe. Long. \\ mm. 



Joints 3 — 6 of antennae slender and almost similar, 7th rather longer, longer 

 than broad, 8th to 10th larger, sub-equal, each about as long as broad, the first of 

 them being, however, rather more slender, terminal joint acuminate, slightly longer. 

 Head broad, eyes small, placed quite in front ; palpi elongate. Thorax longer than 

 broad, bearing much pubescence, quite destitute of punctures or foveae. Elytra 

 rather narrow, slightly broader at the base than at the thorax, without humeral fold, 

 but with a small longitudinal depression rather nearer to the suture than to the 

 shoulder. 



The male has the anterior femora much dilated, so as to form au arcuate upper 

 margin.
