EXOTIC MICROLEPIDOPTERA. 
Antennas grey. Thorax grey. Forewings grey, or light greyish- 
ochreous mixed grey, more or less sprinkled dark grey ; dorsal 
area paler or more usually whitish ; a slight dark fuscous mark 
more or less indicated on dorsal edge about ^ ; costa often slenderly 
whitish from | to near apex : cilia whitish-grey, on apex and costa 
white. Hindwings rather dark grey; cilia light grey. 
Queensland, Duaringa, Charleville, Brisbane; New South 
Wales, Bathurst, Sydney, Bulli; Victoria, Warragul, Gisborne ; 
S. Australia, Port Lincoln ; W. Australia, Geraldton ; August to 
November, 20 ex. Probably attached to Convolvulus erubescens. 
I have hitherto recorded this as somnulentella , but now perceive it 
to be distinct; somnulentella, which has a dark face, has not 
occurred authentically in Australia or New Zealand. 
Bucculatrix monelpis, n. sp. 
2 . 7 mm. Head, thorax white. Forewings dull white; 
second discal stigma dark grey: cilia white, towards ternus 
greyish-tinged. Hindwings pale grey ; cilia whitish-grey. 
S. Rhodesia, Mazoe, January ; 1 ex. (Coll. Janse). 
Bucculatrix ochromeris, n. sp. 
<5 . 6 mm. Head white, tuft centrally mixed fuscous. Thorax 
white. Forewings white ; markings pale brownish-ochreous with 
a few minute blackish specks; a faint dash on fold about ^ ; 
rather oblique transverse spots on costa beyond middle, and on 
dorsum slightly before this; second discal stigma more blackish- 
speckled : cilia white, a few minute blackish specks near base. 
Hindwings pale grey; cilia grey-whitish. 
Transvaal, Pretoria, November; 1 ex. (Coll. Janse). 
OPOGONA, Zell. 
As already stated elsewhere (Trans. N. Zeal. Inst, lviii, 315), 
the accumulation of transitional forms has made it impossible to 
maintain the distinction between this genus and the typical forms 
of Hieroxestis , which therefore is merged in Opogona and dis¬ 
appears. On the other hand, by gradual additions the scope of 
Hieroxestis had been so far widened that it had come to include a 
number of diverse insects which cannot possibly be associated with 
Opogona , and must be otherwise distributed. The following 
assignments are, therefore, now made. 
Opogona receives omoscopa Heyr. (type of Hieroxestis ), subcer- 
vinella Walk., lithacma Meyr phceochalca Meyr., autogama Heyr., 
pileigera Heyr., indiscreta Heyr., plumbifera Heyr., Jlorea Heyr., 
cyanodesma Heyr., selacta Heyr., heliogramma Heyr., pyrome$ &U& 
Moyr-., caenologa Meyr., horotyca Heyr., thapsonota Heyr., mono- 
sticta Heyr., lutigena Meyr., protomima Heyr., clinomima Heyr., 
conyurata Heyr., iolychna Heyr., citrinodes Heyr. 
Oinophila receives tarsota Heyr., divisa Heyr., and probably 
anachoreta Heyr.
