jurious to cucurbitaceous vegetables; possibly as important in this 
respect as tristis. Present knowledge indicates that the cucumber is 
preferred, as neighboring squash vines have so far escaped attack. 
The familiar measures employed in the control of tristis are indicated 
in the case of the other two species, and in addition I would suggest 
the eradication of the star-cucumber (Sicyos angulatus Linn.), as a 
measure of precaution. 
As it will be of interest to have further precise observations on the 
activities of these potentially destructive species of Anasa, I append 
a table for their discrimination, with the data of their occurrence in 
New England. 
1. Head with tw T o long slender spines projecting forward; color brown, connexivum 
very distinctly banded, terminal antennal segment pale; length 11-14 mm.

Head without prominent spines projecting forward.2 
2. Head with a small tubercle just behind the base of each antenna; color light to 
dark brown, with coarse black punctation, lateral margins of pronotum pale, 
connexivum indistinctly banded; terminal antennal segment dark; length 
14—17 mm. tristis 
Head without such tubercles; color light yellowdsh-brown, lateral margins of 
pronotum concolorous, connexivum distinctly banded, terminal antennal seg¬

NOTES FROM TASMANIA 
By Frank M. Littler, Launceston, Tasmania 
Currant Clearwing Moth. The currant clearwing moth (Aegeria 
[/Sesm] tipuliformis Clerck) has been noticeably on the increase on 
red, white, and black currant bushes in various parts of Tasmania 
during the past few years. So far as is known it has not as yet appeared 
in the southern half of the island. The insect as a pest has been 
known to the writer for the past ten years. Neither raspberries, nor 
gooseberries yet appear to be affected. The perfect insect makes its 
appearance during November, and odd ones may be captured up to 
early January. By May the larvae are nearly full grown, and from 
then until early spring they remain practically quiescent. The length
