completion of the experiments described below, tlie results oi which 

 differ from those of Matheson. He later used caterpillars of P. rapac 

 in attempts to reproduce Matheson's results, but without success. 



In his own experiments the author was unable to get A. glomerulus 

 to attack ordinary caterpillars of P. brassicae. Nor was he apparently 

 successful in inducing them to parasitise the eggs, but' when an attempt 

 was made to rear the caterpillars hatched from them, it was found that 

 of 34 caterpillars no less than 31 proved to be parasitised. Further 

 experiment showed that the explanation of this is that A. glomcyalus 

 oviposits, not in the eggs of tUe host, but in quite newly-hatched 

 caterpillars. On an average 20 seconds are sufficient for the deposition 

 of a batch of eggs, the number of eggs per caterpillar varying from 

 6 to 32. As up to 180 parasitic larvae have been found in one 

 caterpillar, the attacks must be repeated. 



In a similar experiment made with the eggs of Abraxas grossiilariala 

 similar results were obtained.

 Z. pyrina.'] — Zeilsc/ir. lejiss. Insektenbiol., Berlin, xiv, no. 7-8, 

 15th December 1918, pp. 198-200. 



The Cossid moth, Zeuzera Pyrina, L., has often been stated to be 

 especially a pest of horse-chestnut, but this has no foundation in fact. 

 A number of references are given to records of other food-plants. The 

 author himself has observed it on birch and elm.

In 1900 Dr. A. Zimmermann published in the Annales du Jardin 

 Botanique de Buitenzorg a paper on leaf spots due to Rhynchota and 

 other pests in Java, only a few of which were named. The author has 

 now been able to study Zimmermann's original material, and gives a 

 list with notes on the literature, synonymy, and food-plants. 



The Pentatomid bug, Antestia partita, Wlk. {plebeia, Voll.), is an 

 important coffee pest ; Zimmermann found it also on Fraxinus edenii, 

 Morinda citrifolia, and M. bracteata. Alaleus fiavidipes, Stal, was 

 found on Thimbergia alata, and Duliniiis cone hat iis.Dist., on Morinda 

 citrifolia. Mertilia malayensis, Dist., was reported as an orchid pest by 

 Zimmermann [R.A.E., A, vii, 39] ; this Capsid bug has been imported 

 into Germany with orchids from the East Indies. A species allied to 

 Mertilia is Bromeliaemiris bicolor, gen. et sp. n., briefly described here ; 

 Zimmermann found it on various Bromeliaceae. The Jassid, Typhlo- 

 cyba crythrinae, Konings., is a well-known pest of Erythrina (dada.p), 

 used as a siiade for coffee. Another species of Typhlocyba was recorded 

 by Zimmermann from Aralia guilfoylei.

 1919, p. 240. 



In galls of Pistacia terebinthus, caused by Pemphigus derbesi, Licht., 

 and P. pistaciae, L. {cornicularis. Pass.), obtained from Macedonia, the 

 author found the caterpillar of a Microlepidopteron believed to be 

 Stathmopoda guerini, Stn.
