to Java these Capsids must have wild food-plants, possibly Shima 

 noronhae, a Ternstroemiaceous plant with leaves resembling those 

 of tea. The eggs are laid in the tea flower-bud, and this must injure 

 the bud more than the puncture does. Two parasites, a Chalcid and a 

 Proctotrupid, were reared from the eggs. The egg-stage probably 

 lasts 10-14 days. The larvae reach maturity in 9-10 days ; the 

 first moult taking place a day after hatching, the others following at 

 intervals of 1 or 2 days. The larvae are sluggish, unlike the adults 

 which are restless and active flyers.

 Crioceris spec. {suhpoUta, Motsch.?). [The Life-History of a 

 Crioceris injurious to Orchids.] — Treubia, Batavia, i, no. 2, August 

 1919, pp. 82-89, 5 figs, 2 plates. [With an EngUsh summary.] 



The egg, larva and adult of a Chrysomelid beetle, possibly Crioceris 

 subpolUa, Motsch., found in Java and Sumatra, are described. Both 

 larvae and adults injure various kinds of orchids, eating the flowers 

 by preference, but also the fruits and leaves. The eggs are laid on the 

 flowers or flower-stems and hatch in 4-5 days. The freshly-hatched 

 larva bears the egg-shell on its back during the first day, after which 

 it becomes covered with a thick layer of its own faeces. In 9-10 days 

 it reaches maturity, loosens the layer of excrement and constructs 

 a cocoon of a white frothy substance attached to some part of the 

 plant. Before pupating it remains inactive in the cocoon for 4-6 

 days. The pupal stage lasts 6-7 days and the beetle remains 2-3 

 days in the cocoon before emerging. The whole life-cycle thus lasts 

 from 25 to 31 days.

 pinen [Curtillinen]). [A Communication on the Javanese Mole- 

 Crickets.] — Treubia, Batavia, i, no. 2, August 1919, pp. 90^-97,

The conclusion is arrived at that there are two species of mole- 

 crickets in Java, Gryllotalpa hirsuta, Burm., and G. africana, P. B. 

 At Buitenzorg all the males of G. hirsuta proved to be apterous and the 

 females always macropterous. From Klaten an apterous female of 

 G. hirsuta was received. 



As regards G. africana there is only a small percentage of brachyp- 

 terous males at Buitenzorg, and the females there are fully winged. 

 From Klaten brachypterous males were received in comparatively 

 large numbers and the females also included a small percentage of 

 brachypterous individuals. There does not appear to be any previous 

 record of brachypterous examjiles of G. africana or of apterous ones of 

 G. hirsuta.

 described.
