Hesperilla gracilis, spec, nov, 

 PI. II., fig. 7. 

 This HesperiJIa lian been captured near Salisbury, Adelaide 

 Plains, and is the smallest known to me. Its body is slender 

 in proportion to its size ; the thorax and head are black, 

 the abdomen also, but the segments edged white. The 

 upper side of the wings is of a uniform dark bronze brown ; 

 the anterior wings are marked with a white zigzag band near 

 the margin, and a short white bar near the middle. The pos- 

 terior wings are without any mark. The colour of the under- 

 side is much lighter ; the anteriors marked with small w^hite 

 spots, the apical one being the reproduced end of superior 

 band ; the posterior wings are margined with black and white 

 spots alternately ; five white spots form an outer, one large 

 and four minute ones a central, and one large and two small 

 ones a basal band. The markings of the male are narrower 

 than those of the female. 



I append the genus Synemon, peculiar to Australia, to the 

 Papilionida^, although aware that it is placed by eminent 

 entomologists among the Agaristidae, because it appears to me 

 that in the whole its species present in their appearance (as 

 the venation of wings, the clubbed antennae, their habit of 

 flight, &c.) more affinity to the former than to the latter, and 

 that the genus is a link that joins the Hesperidae to the day- 

 flying moths.

This is the commonest species of the genus, though nowhere 

 numerous. The anterior wings are brown, thickly dotted with 

 white specks, and darker and the markings more variable and 

 indistinct. The posterior wings are black, with deep-red 

 markings, viz., three spots near the margin, a zigzag band 

 nearly across, a large irregular spot near the base. The bars 

 and other markings are reproduced on the underside, but
