INSPECTS OP" THE ISLAND. 
By H. Illidge. 
Our visit to Stradbrcktr* Islaud took place, in so far as- 
entomology was coneerned. at an unseasonable time ; hence^ 
f./*w insects were in evidence. \Vn have, however, on 
previous visits during the early spring seen the place close 
to - our late camp alive with butterflies and motlis. also 
I)cetles of many kinds. 
It is rich in tine ITymenoptera (Thynnidie, with 
apterous females, are numerous in species), Diptera, 
Neiiroptera, &c. All these have species which arc almost 
peculiar to it, and are not found round Brisbane. Amongst 
these are two butterflies of much interest, as they are at 
present only known elsewhere from the neighbourhood of 
Duaringa, west of Rockhampton. Thes.‘ are known to 
science under the names of NesaJycirnq alboi^fricfa and 
Ogtjris Baruardi, both described by the late AV. H. ]^liskin, 
and the latter in honour of the late ilr. Barnard, of Coomoo- 
boolaroo. a pioneer naturalist of Australia, and revered by 
all students of our fauna. 
Of the butterflies which were obs -rved the most 
notable was Troidfs richmondia : but, this having been on 
the wing for some days, specimens wen- not in good con- 
dition. 
In Coleoptera. specimens cf D ade riLs ergfh t urns were 
taken on a fallen Callitris. These were accompanied by a 
species of Evania (?) (Ilymenoptera ) , probably parasitic 
on its larva*. The beetle is interesting as alfecting this 
beautiful tree throughout East Australia, but does not seem 
to damage the healthy plant, for only unsound or disea.sed 
trees are attacked. Timber-getters often unwittingly cause 
trouble when they cut out pieces of bark and wood to obtain 
samples of the timber, as this immedialely gives wood- 
boring insects a suitable opportunity for depositing ova. 
In addition to the Ihadoxus erythrurus, two or three 
interesting longicornes, a weevil, .Esioifs Jpucvrus, and 
many other small beetles affect both decaying trunk and 
bark. A clerid beetle, allied to Omadius, was also alighting 
on the fallen trunks, but was so active, and in colour so 
7uuch like the bark, that only one sp *cinien was seciired. 
C leridtV appear to be. so far as is known to us, predaceous 
both in larva and image). iMaiiy ^species are found on 
flowers, which they seem to frequent for the purpos? of 
preying on minute insects.
