LEPIDOPTERA. 



By OSWALD B. LOWER. 



Taking the collection as a whole, it is exceedingly poor, and 

 adds but little to ouv entomological fauna. This is the more to 

 be regretted, as the opportunity for traversing the same ground 

 may never occur again. A remarkable feature in the collection 

 is the inclusion of several world-wide species, notably, Heliothis 

 armiger, Hiibn., and Nomopldla noctuella, Sch., showing how 

 these introduced (?) species adapt themselves to different localities 

 and conditions. Another noticeable feature is the paucity of 

 Q<]cophorid!e in the collection. This family is represented in 

 Australia by at least 2,000 species — 1 have 230 species in my 

 own collection, collected within 20 miles of Adelaide — and to 

 find only three representatives in the collection is, to say the 

 least, perplexing. It will also be noticed that the date of ap- 

 pearance of Trictena labyrintltica, Don., is very much at variance 

 with the usual time. Most of specimens emerge in and around 

 Adelaide during April and May, whereas those from the Interior 

 were captured during October, at which time I liave never ob- 

 served them. In commenting on the general condition of the 

 specimens received, I may say that the whole are in very fair 

 order and, with the exception of those described as new, are 

 taken at various periods both at Parkside and Blackwood. The 

 collection, if it does nothing else, shows the distribution of the 

 various species ; but one would have thought to have seen more 

 of the Western Australian forms. The season just closed has 

 been a very poor one from an entomological point of view, so far 

 as Adelaide and its environs are concerned, and. considering the 

 reports from the Interior, insect-life was probably at a premium 

 during the progress of the Expedition. 



The following comprise the species received : — 



Hetepoeera. 



SYNEMONIDiE. 

 Synemon, Doihhleday. 

 S. PYRRHOPTERA, It. sp. Only One specimen. A male of this 

 fine species captured at Eraser Range, 14th October, 1891. 



S. SOPHIA, white var. One fine specimen. A female from 

 Murchison district, February, 1892. This differs somewhat from 

 the type, being more prominently marked with the white on the
