Recent Bulletins of the Delaware Experiment Station.* — In Bulletin No. 14 

 of this Station, which has been long delayed, Prof. A.T. Neal, the Director, 

 reports the results of some experiments with fertilizers in combating 

 insects, in which he comes to the conclusion that nitrate of soda excels 

 potash and jjhosphoric acid compounds in its powers to protect plants 

 against cut-worms and other insects affecting young corn. Mr. M. H. 

 Beck with follows with a short account of Cr ambus caliginosellus, which 

 he found feeding upon corn at the Station and which we have already 

 referred to on page 42 of Volume iv. As this insect is one of tlie old 

 Clemen sian species there would seem to be little need of the technical 

 description which Mr. Beckwith gives. 



In Bulletin No. 18t Mr. Beckwith treats of the Strawberry Weevil 

 on Images 11 to 16. This insect, it seems, has been very destructive to 

 the strawberry crop in parts of Kent County, Delaware, during the 

 early summer of 1892, and Mr. Beckwith has made careful observa- 

 tions on the life-history of the insect, his results coinciding in the main 

 with those which have been made in the vicinity of Washington and 

 which were given in full in the last number of Insect Life. 



Bulletin No. 90 of the New Jersey Experiment Station. ^Ill this Bulletin 

 Prof. J. B. Smith, Entomologist to the Station, treats of grasshoppers, 

 locusts, and crickets, particularly with reference to their injury, or 

 supposed injury, to the cranberry crop. He finds that the general idea 

 among the cranberry growers is that the true or short-horned locusts 

 are responsible for the peculiar and common damage to the berries 

 themselves, which consists in eating directly into the seed from one 

 side of the berry. Prof. Smith shows that this damage is not done by 

 Acridiidai but by Locustid^, and probably by one or two sx)ecies of 

 katydids. This point he reaches by comparison of the heads and di- 

 gestive systems, as well as by examinations of crop contents and actual 

 feeding experiments. He gives original illustrations of the mouth-parts 

 of insects of these two families, as well as of certain crickets, and also 

 shows by photographic reproduction the inner surface of the crop of 

 one insect of each of these families, and also of a cockroach. The re-
