besides size, in the paler colour, in the absence of the rudimentary elytra, 

 and in not having the abdominal segments terminating in spines. 



The axithor considei-s that tlie imagines live more than one 3^ear, and 

 that the species passes the winter either as larva or as imago. The eggs 

 yielded numbers of the minute hymenopterous pai-asite, Presticichia 

 aqiiatica Lubb. 



In their estuarine occurrence, in places which were, apparently, very 

 devoid of aquatic vegetation, these Danish specimens differ widely from 

 British examples, so far as at present known. The latter have most 

 frequently been found associated with a broad-leaved Potamogetoii in 

 inland streams, wdiere certainly there would be no chance of their 

 meeting with the bivalve Mollusca mentioned above. Nevertheless, 

 after a careful comparison, I can see no difference other than that of 

 size between the British and Continental examples, and I do not think 

 size alone could justify their separation. 



Gadeau de Kerville took the species abundantly in the Seine, and 

 found it there feeding upon the larva of the Coleopteron Haemonia, 

 and he believes that it preys also upon the Mollusca Faludina vivipara 

 and Sythinia tentaculata (see Kirkaldy, o^j, cit. p. 152).

Salphigns ater Payh. iii East Lothian. — I Lave to record the capture of an 

 example of Salpini/us ater Payk. This flew into our niess-iooin on the evening 

 of June 10th. 1 have since had the opportunity of comparing it critically with 

 S. aeratui, aud certainly its perfectly black legs appear to differentiate it, 

 although one is inclined to think that the two species might well be merged 

 into one. — J. E. Black, Peuston, East Lothian : July 1917. 



Metatropis rufescens H. S. in Berkshire and Oxfordshire. — On June 9th, 

 1917, in Bagley Wood, Berks., 1 was delighted to find the elegant bug Meta- 

 tropis rufescent H. S. while sweeping Circaea lutetiana L., and on carefully 

 examining some large patches of this plant, saw the insect in considerable 

 numbers. Commander Walker tells me that he swept single examples of 

 Metafrojns from its food-plant in Prattle Wood, near Islip, Oxon., on June 5th 

 and July 3rd, 1917. — H. BnixxiiN, Myrtle View, Windmill Road, Headington,
