orange, very destructive in California. After extended search he 

 sent the CoccinelHd Cryptognatha iJavcscens from Saharanpur, but 

 they died in transit. Later he found an internal parasite at the same 

 place and at Lahore. This species was described by the writer as 

 Prospaltella lahorensis. Small infested orange trees were placed in 

 Wardian cases and sent to Florida. Eight adults and several pupae 

 survived the journey, but they arrived at the wrong time of the year 

 and perished, the white flies being then in the dormant pupal condition. 

 It was upon this trip that Doctor Woglum debarked at Gibraltar and 

 went ui> to Valencia, Spain, to demonstrate to the Spanish agricul- 

 tural engineers the proper way to fumigate Citrus trees for scale 

 insects. 



The introduction from France of the egg-parasite of the European 

 elm leaf beetle, which was begun in 1905, has been repeated several 

 times since then, but the species has not taken hold in the L'nited 

 States. It apparently existed through a whole year at Melrose High- 

 lands, but eventually died out. There is a bare possibility that it may 

 have persisted in some one of the numerous places in which it was 

 liberated, but it has not been found. An especially favorable place 

 was found several years ago on a badly infested clump of European 

 elms on the estate of Admiral Taylor of the United States Navy at 

 Gordonsville, Virginia. It was hoped that at this ])lace the parasites 

 would take hold, but there has been no observable result as yet, and 

 the fine old trees, I am told, are in their last stages. 



In 1924 a Dipterous parasite {Erynnia nitida) was introduced from 

 the South of France with the aid of W. R. Thompson, then stationed 

 at Auch. Si:)ecimens sent to Washington were liberated on Admiral 

 Taylor's place, but the s{3ecies has not been recovered. 



The very large-scale ex|>eriments made by the Bureau in the intro- 

 duction of many parasites and predators of the gipsy moth and the 

 brown-tail moth from Europe as well as from Japan were fully 

 described in 1911 in Bulletin 91, and need l>e given no space here. 

 Shorter bulletins have been published from time to time giving 

 accounts of the progress of individual imported species, and Technical 

 Bulletin 86 of the United States Department of Agriculture, pub- 

 lished in August, 1929. gives a full account by A. F. Burgess and 

 S. S. Grossman of the status of the many importations down to that 

 date. 



Two other large-scale attemi)ts to import natural enemies of in- 

 jurious insects of extreme importance have been made by the Bureau, 

 one the bringing in from Europe and from the Orient of the parasites 

 of the European corn borer. The progress of this attempt has been
