OF NEW SOUTH WALES. 305 



of Hamadayas, all differing more or less from species known to 

 me, but all having very much the general aspect of the Polynesian 

 Fauna. One circumstance connected with this group is worth 

 noticing. There are no specimens in the collection of Danais 

 Erippus, Cram., an American species which a few years ago 

 succeeded in crossing the Pacific Ocean, and establishsng itself in 

 Australia. The absence of this insect from the New Ireland 

 collection helps to indicate the route by which it passed the ocean. 

 Two years before the first appearance of the butterfly on the east 

 coast of Australia, I received numerous specimens from the New 

 Hebrides and islands to the south of that latitude, so that there 

 is reason to assume that the general course of the migration which 

 seems to have occupied several years, was, as regards the western 

 portion of the Pacific, far south of the equator. 



The Lycaenidse number thirteen species, all, I believe, of the 

 genus Cupido; among them the Cwpido Cleo as, Guer., figured 

 and described in the voyage of the Coquille. There are seven 

 species of the Hesperida?, all of well known genera. 



In all there are sixty-three species of butterflies. 



Among the day-flying moths there are some gems. 



There are two species of Nyctalemon, one probably the A. 

 Achillaria of New Georgia, the other quite new to me; one 

 new and beautiful species of Agarista ; Cleis podicalis, Guer., and 

 another species of the same genus. Of Hypsa and Nyctemera 

 there are several handsome species, as also of Eumelia, Micronia, 

 Erebus, and Trigonotus. 



The Hemiptera are neither numerous nor remarkable. A 

 Scutellaria, a few species of Seduvius, and a few other common 

 forms constitute the whole collection of this order. 



The Orthoptera seem to be of great size, and tolerably 

 numerous. A large Eurycantha is the most formidable looking ; 

 the others are mostly insects of universal occurrence. 



The Homoptera consist only of two speciesof Cicada and a 

 small tree-hopper. 



The Hymenoptera of a Poftipilus a Bembex, an Odynerus, and 

 two Ichneumonida, one of them of a novel and very curious form.
