deep. The burying of material containing pupae gave similar results 

 and although many larvae and pupae are thus destroyed, it cannot 

 be considered as a possible means of extermination. A comparison 

 of treated and control plants does not reveal any marked protection 

 due to the application of arsenicals. A Hymenopterous parasite, 

 Tricliogramrna minuium, Riley, was found parasitising about 30 per 

 cent, of the eggs of the second generation and is apparently widely 

 distributed. Of the six Dipterous and six Hymenopterous parasites 

 known, Compsilura concinnata, Meig., is the only imported species. 



A resolution was passed that most energetic efforts on the part of the 

 Federal and State agencies should be made to control and if possible 

 exterminate the pest, including vigorous quarantines to prevent its 

 distribution. It is urged that Congress should make an appropriation 

 of £4,000,000 for the year 1920 to carry out this work, and for this 

 purpose a committee representing the Commissioners of Agriculture, 

 official Entomologists and the Plant Pest Committee should be 

 appointed. 



This bulletin ends with a paper by Mr. C. L. Marlatt explaining that 

 the action of federal quarantine has so far been withheld pending 

 recommendations which shall result from the conference. It is apparent 

 that any quarantine covering merely known invaded areas would 

 not be worth while or practicable ; to be efficient it must cover New 

 England and New York as a whole. The restrictions should cover 

 all articles of general commerce for food purposes which have been 

 shown capable of carrying the pest. The regulations could be modified 

 to allow of movement by inspection and certification in the uninfested 

 territory.

In this continuation of a previous list [R.A.E., A, iv, 438] some of 

 the information given has been noticed elsewhere [R.A.E., A, iv, 96, 

 387 ; V, 359]. 



The insects dealt with include : — Pentodon bengalense, Arr., which 

 is probably widely distributed over India, but is only reported from 

 Peshawar as a pest. The adults begin tunelling at the soil surface 

 in sugar-cane until they reach the base, causing a dead heart and often 

 eating right through the base. Larvae collected on 20th May 1906 

 and 1st May 1909 pupated on 24th June and 2nd July respectively, 

 the adults emerging on the 3rd and 12th July. Larvae of Anomala 

 hengalensis were also found attacking sugar-cane underground. They 

 hibernate in the larval stage, pupation occurring about the end of 

 March and the adults emerging about the middle of April. Consider- 

 able damage is caused to bael trees {Aegle tnarmelos) in June and July 

 by a Chrysomelid beetle, Clitea picta, of which the larva is described. 

 The larvae burrow in the midribs of leaves, tender shoots, spines, 

 axils of branches and young setting fruit, whilst the adults eat holes 

 in the leaves. Pupation occurs in the larval burrow or in the soil 

 and lasts 5 or 6 days. The fruit-flies, Dacus (Chaetodacus) diversus, 

 infesting plantains in Burma, and Stictaspis cemtitina and S. striata
