 fulvicornis, F., Hym., Tenthredinide. — Insecta, Rennes, xi, 1921, 

 pp. 6-23, 13 figs. [Received 9th October 1922.] 



The life-history and habits of Hoplocampa fulvicornis, F., are des- 

 cribed in greater detail than formerly [R.A.E., A, ix, 463]. It has 

 generally been considered that the species of sawfly found infesting 

 plums is H. fulvicornis, that in apples being H. testudinea, that in pears 

 probably H. brevis, while that attacking apricots is undetermined. 

 The author believes that the larvae found in pears and in apricots 

 are those of H. fulvicornis ; he has proved by experiment that the 

 larvae of this species are polyphagous and that they can be reared 

 to maturity on either tree.

 Subtribe Macrosiphina (Homoptera). — Phvsis, Buenos Aires,

The author proposes to publish from time to time the results of 

 his studies on Argentine Aphids, of which this paper forms the first 

 part. Descriptions are given of those species that have come actually 

 under his observation ; those recorded by" other workers are dealt 

 with only in the keys. Keys are given to the genera of the sub- 

 tribe Macrosiphina, and to the species of the genera Macrosiphum, 

 Aulacorthum and Macrosiphoniella. 



The species dealt with are : — Macrosiphum lizeriamim, sp. n., found 

 on Sonchus and various Composites ; M. rosea, L., on cultivated 

 roses ; M. solanifolii, Ashm., on Watsonia and Lactuca ; M. sonchi, L., 

 on Sonchus and Cichorium, and occasionally injurious to cultivated 

 chicory ; M. urticae, Schr., on Urtica, Malva and Geranium ; Aula- 

 corthum eumorphum, sp. n. (allied to A. convolvuli, Kalt.), on Vinca 

 major; A. pseudorosaefolium, sp. n., on cultivated roses; Macro- 

 siphoniella heretica, sp. n., on leaves of an undetermined Composite ; 

 M. chrysanthemi, del Guer., found commonly on cultivated chrysan- 

 themums {M. sanborni. Gill., is very closely allied to this species and 

 may prove to be the same, in which case chrysanthemi would become 

 a synonym of it) ; M. tanacetaria, Kalt., var. bonariensis, n., on 

 Tanacetum vulgare ; Rhopalosiphum [Amphorophora) lactucae, Kalt., 

 on Sonchus (this species seems to agree with Van der Goot's definition 

 of R. ribis, L., which, according to Theobald and others, is synonymous 

 with R. lactucae, Kalt.) ; Capitopiiorus tctrarhodus, Wlk., on cultivated 

 roses; Myzus persicae, Sulz., common on Bellis, Cynara, Malva, 

 Brassica, Solamim, Prunus, Beta, Vinca, Abutilon, Tulipa, etc., but 

 seldom found on peach, indicating that the usual migration occurring 

 in North America does not take place ; and Neomyzus circumflexum, 

 Buckt., on Vinca major.

In the author's opinion, the gall-making Psyllid, described by 

 Brethes as Gyropsylla ilicicola [R.A.E., A, x, 592] is the same as the 

 species described by himself in Marcellia, xvi, pp. 103-107, 1917, as 

 Pauroccphala spegazziniana.
