 dated 28tli February 191 G, from Redia, Flwence, xi, no. 1, 

 pp. 299-303, 3 figs. 



It is believed that there have been hitherto no records of Somaliland 

 Aphids. Three new species from that country are described in this 

 paper, viz. :■ — Aphis calotropidis and A. paoli on Calotropis procera, 

 and A. foveolata on Pergidaria extensa. 



Berlese (A.) & Paoli (G.). Un endofago esotico efficace contro il 



Chrysomphalus dictyospermi, Morg. [An introduced endophagous 

 parasite of C. dictyospermi, Morg.]- — Separate, dated 24th February 

 1916, from Redia, Florence, xi, no. 1, pp. 305-307, 2 figs. 



For some years the Royal Entomological Station at Florence has 

 been searching for a natural means of control against Chrysomphalus 

 dictyospermi, Morg., and a description is given here of Prospaltella 

 lounsburyi, Berl. and Paol., an endophagous Chalcid, which is a 

 native of Madeira, sent by Prof. C. P. Lounsbury. Owing to its small 

 size, this Chalcid attacks the female nymphs of C. dictyospermi as well 

 as the adults. The percentage of parasitised females varies from 

 40 per cent, in the case of adults to 60 per cent, in that of the nymphs.

 Colombia.] — Revista Agricola, Bogota, i, no. 10, October 1915, 

 pp. 585-587. [Received 7th March 1916.] 



This paper refers to the need for studying the injurious insects in 

 Colombia and gives instructions for killing, preserving and packing 

 them when collected. 



Der Einfluss des guten Wetters zur Bliitezeit auf den Heuwurm und 

 Sauerwurm. [The influence of good weather at flowering time 

 on the two generations of Clysia ambiguella.] — Schweiz. Zeitschr. 

 Obst.- u. Weinbau, Frauenfeld, xxv, no. 5, 8th March 1916, 

 pp. 85-86. 



It has been an old belief of vine-growers that fine weather at flowering 

 time was the best control for both generations of Clysia ambiguella. 

 This belief was exploded in 1915, when the weather in the Palatinate 

 was very fine at flowering time and yet serious damage was caused by 

 this pest, which extended its injury to parts of the vines not usually 

 attacked, such as the stems, probably on account of the dry weather. 



KiRscHMER (H.). Schutzschirm ftir Klebringe. [A protective shade 

 for stickv bands.] — Deutsche Landwirtschaftl. Presse, Berlin, xliii, 

 no. 3, 8th January 1916, pp. 20-21. 



The adhesives used for banding trees against Cheimatobia brumata, L., 

 are very apt to harden through exposure to frost and rain, and thus 

 become useless. Their utility may be greatly prolonged by protecting 

 them with a metal shade, similar in shape to a lapip-shade and placed 

 like a collar round the trunk just above the banding. These metal 

 shades last for years and a size suitable for young fruit trees only 

 costs about 2d.
