GooDEY (T.). On the Susceptibility of Clover and some other Legumes 

 to Stem-disease caused by the Eelworm, Tylenchus dipsaci, sjm. 

 devastatrix, Kiihn. — //. Agric. Sci., Cambridge, xii, pt. 1, January 

 1922, pp. 20-30, 1 plate. 



This is a preliminary note on the results obtained from an attempt 

 to procure a numerical expression of susceptibility of clover and other 

 plants to stem disease caused by the Nematode, Tylenchus dipsaci, 

 Kuhn. A comparison is drawn between this disease and stem rot 

 caused by the fungus, Sclerotinia foliorum. 



The technique employed is described, and the results are given in 

 detail in the form of tables. Examination of the figures shows that 

 all the varieties of red clover tested are very susceptible to attack and 

 fall into a common group to which cow-grass and kidney vetch also 

 belong. Except for one or two details the results in general agree 

 with those of Amos [R.A.E., A, vii, 441]. The author found that 

 seedlings of sainfoin are very slightly susceptible, whereas Amos never 

 found this plant attacked. To avoid this pest, trefoil, lucerne, sainfoin 

 or large white clover should be sown in place of red clover, cow-grass, 

 alsike clover and kidney vetch.

The insects observed on the flowers of coconuts and thought to be 

 active agents in pollination were the Diptera, Miisca domestica, L., 

 and several species of Lucilia, and the Hymenoptera, Vespa luctuosa, 

 Sauss., Rhynchium atriim, Sauss., Apis indica, F., and Trigona hiroi, Fr.

The new Histerids from India here described are Platysoma 

 {Platylister) huteanum, from Saharanpur, United Provinces, taken on 

 Butea frondosa (apparently under the bark), and Trypeticus heesoni, 

 taken in Assam in the trunk of an unidentified tree.

Saperda populnea, reared in galls at Montpellier, was found to have 

 many parasites, but the most unexpected was Apanteles hoplites, 

 obtained in several instances. No species of Apanteles has previously 

 been recorded as parasitic on Cerambycids. A. hoplites has been 

 reported in Germany from larvae of Rhynchites hetideti and Melasoma 

 {Lino) tremvtlae, and has been observed in England as a parasite of 

 Gelechia pinguinella, all of these being pests of poplar.

The fact that Phthorimaea operculella, Z., has been recorded from 

 Algeria, and more recently from Morocco, indicated that it might be 

 expected to occur also in Tunisia. It has in fact been found, but only
