have sought hibernation quarters on the woody stems, being then in 

 the 3rd and 4th stages. There is therefore only one generation in 

 a year, development being very slow. All stages of the insect are 

 described.

Anasa tristis, DeG. (common squash bug) was until recently the 

 only species of the genus known to occur in New England. In 1914, 

 A. repetita, Heid., was reported from Massachusetts and subsequently 

 this species was observed in large numbers on star-cucumber. Recently 

 it has been known to feed on cultivated cucumber in sufficient numbers 

 to have caused injury if hand-picking had not been employed as a 

 preventive measure. The same record applies to A. armigera, Say, 

 this species being so numerous on cultivated cucumber in mid- August 

 that some plants were destroyed. These two species are evidently 

 increasing in New England and are likely to become seriously injurious 

 to Cucurbitaceous vegetables, cucumber evidently being the preferred 

 food. Control measures that are used for A. tristis should be employed, 

 and in addition the eradication of star-cucumber {Sicyos angulatus) 

 is advised. A key is given for the differentiation of these three species, 

 with the date of their occurrence in New England.

Aegeria tipuliformis, Clerck (currant clearwing moth) has been 

 increasing in Tasmania during the past few years on red, white and 

 black currant bushes, but has not yet been observed in the southern 

 half of the Island [see this Review, Ser. A, vii, p. 48]. An Ichneumonid 

 parasitic upon it is fairly abundant and does not appear to be hyper- 

 parasitised ; it may therefore be an efiective check. The destruction 

 of all badly affected currant bushes, the vigorous pruning of bushes 

 during the winter in affected plantations and the burning of all parts 

 cut away, care in selecting cuttings for striking, and spraying the 

 bushes with lead arsenate immediately after the fruit has been picked, 

 have produced satisfactory results. 



As a consequence of the unusually rainy season of 1916-17 there 

 was a super-abundance of plant growth and many pests were numerous, 

 Nysiits vinitor (Rutherglen bug) being particularly abundant. Early 

 in the year the immature insects were migrating in countless numbers 

 from an area of reclaimed land in Launceston into a park in one 

 direction and along the gutters of the public streets in another. Steps 

 were then taken to isolate the breeding ground with coal-tar barriers. 

 The migration of further immature forms to the park was checked 

 by spraying, and the weeds on the breeding area were cut and burnt, 

 A large number, however, escaped and it is feared that in the coming 

 spring the insect will be very abundant. Only two instances of 

 damage were reported, once to garden plants and once to tomatoes. 



Cydia {Carpocapsa) pomonella (codling moth) has only one generation 

 in a year in Tasmania, but the hatchings are extended over a long 

 period. Lead arsenate has almost entirely superseded Paris green
