the so called Goettingen cart, which is described and figured ; spraying- 

 operations are also useful, but must be carried out before flowering. 

 Lixus ascann,Ya,Y. albotnarginatus, Boh., appears in April and remains 

 all its hfe on mustard ; the females oviposit either in the stem or iji 

 the petioles of the leaves near the roots ; the larvae hatch at the end 

 of May and penetrate through the centre of the stem in the direction 

 of the root. Early crops are most likely to suffer from this weevil. 

 against which the introduction of mustard into a rotation of crops is 

 advised. Trap crops are also recommended, to be sown in strips 

 along the ends of the fields where mustard was gro's^ai the previous- 

 year, and to be destroyed in the first half of June. Lixus bicolor. 

 Panz., occurs occasionally on mustard ; its importance has not yet 

 been investigated. Omophlus pilicoUis, Menetr., is found everywhere 

 in the steppes on mustard and other plants and devours the flowers. 

 Podonta daghestanica, Reitt., occurs on the lower Volga, in the 

 Crimea and in Caucasia, and also devours the flowers, as do various 

 Meloiid beetles, such as : — Mylahris (Zonabris) 4:- punctata, L., 31. 10- 

 punctata, Oliv., M. li-pimctata. Pall., M. niacidata, Oliv., M.floralis, 

 Pall.. M. impar, Thunb. {grisescens, Tausch.). and Lgdus syriacvs, L. 

 All these insects are useful in destroying egg-clusters of locusts, but as 

 the control of the latter can now be effected by other means, they 

 should be destroyed by spraying with quassia emulsion or tobacco 

 decoction or by dusting with tobacco, if they occur in large numbers. 



Athalia spinarum, F., is the only Hymenopterous pest of mustard 

 in Astrachan, where it appears at the end of May. Usually there are 

 two generations, a spring and an autumn one, but in Astrachan there 

 is probably a third. The Chalcid, Perilampus splcndidus. Dalm., has 

 been reared from the larvae. Destroying weeds, trap crops, spraying 

 with djipsin, urania green or calcic arsenite, and harrowing the 

 infested fields after removing the crop, are recommended. The 

 Rhynchota which damage mustard, include •.—Enrydema festivimu 

 L., E. ornatum, L., Carpocoris piirpureipennis, Deg., and Lygaeuf^ 

 {Spilostethus) equestris, L. Their importance is not great, unless they 

 are present in large numbers.

This report gives details of the life-history of various insect pests. 

 On the 8th June some winged Aphids were found on Galium idiginosuntr 

 (swamp bed-straw). They greatly resembled winged forms of Myzu» 

 cerasi, F. ; larvae in the first stage were also present, but the absence 

 of both wingless forms and nymphs showed that the insects had
