210 THE ENTOMOLOGIST. 



The first of the Aphidides group of the subfamily Aphidinae, 

 and one of the most prevalent, was Siphonophora roscB, Linn., 

 which was seen upon the young shoots of both wild and cultivated 

 roses throughout the summer, as well as upon the under side of 

 the leaves of adjacent Aquilegia vulgaris at the end of July ; from 

 these latter I bred several parasitic Aphidii. S. scabiosce, Schr., 

 I have not found here, but I took many apterous females and 

 larvae on the stems of an unrecorded food-plant, Dipsacus sylves- 

 tris, at the Haven Street Woods, in the Isle of Wight, at the end 

 of June, 1907. It was August 22nd last year before I looked for 

 S. granaria, Kirby, but harvest had hardly begun, and I at once 

 found both imaginal forms commonly on some adventitious ears 

 of wheat in the garden, though all these were dead (fourteen of 

 them on one ear had been " stung," and will doubtless produce 

 Buckton's Ephedrus ylagiator or Lygocerus carpenteri, cf. Mar- 

 shall, Bracon. d'Europ. ii. 544), and one or two live apterous 

 females on barley-ears in adjacent fields. Apterous S. hieracii, 

 Kalt., were very rare beneath the flower-heads of Hieracium in 

 early August, associating with a few females and pupae of A2)his 

 rumicis. As early as June 1st larvae of S. milUfolii, Fab., ap- 

 peared on the flower-stalks of Chrysanthemum segetum, and in 

 early August both winged and apterous imagines have been 

 fairly common on the stem of both this plant and Achillea milli- 

 folium, becoming abundant by the middle of the month. No 

 Aphid has been specified as the victim of Diodontus tristis ; on 

 17th last year I saw a female of this Fossor alight on a flower- 

 head of C. segetum, about 2 p.m. in dull and windy weather, walk 

 below the flower, down the stem, over three or four larvae of the 

 Siphonophora, of which she seized the following one in her 

 mandibles with a sudden snap ; she immediately rose in the air, 

 and, after one or two circlings, made off with it ; the larva was 

 about one-third grown {cf. Buckton, ii. 167). At the end of July 

 I have found S. pisi, Kalt., in all its stages, not very commonly 

 on garden peas and the leaves of Bursa bursa-pastoris ; it is not 

 common enough to have been a pest either year. In 1903 I took 

 it near Ipswich on Urtica dioica as late as October 27th. S. rubi, 

 Kalt., has not been observed till the first week in August, when 

 both imaginal forms and quite young larvae occur on the under 

 side of leaves of Eubus fruticosa, with Aphis urticaria. S. urticce, 

 Kalt., has been scarce ; I have taken only one apterous female, 

 still attached to the pupal skin, on Urtica dioica, on August 2nd. 

 The distinct S. avellance, Schr., also appears rare, since of this 

 I have only found an apterous female beneath a leaf of Corylns 

 avellana early in June. Larvae, pupae, and apterous forms of 

 S. tanaceti, Linn., abounded in the heart of a constantly-mown 

 dandelion on a lawn on August 13th, 1907. Beneath leaves of 

 Tussilago farfara numerous dead S. tussilaginis, Walk., both 

 winged and apterous, with a few larvae, were found early in the
