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

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

 reports the results of some experiments with fertilizers in cond)ating 

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

 potash and phosphoric acid compounds in its powers to protect plants 

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

 Beckwith follows with a short account of Crambns 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 

 Clemensian species there would seem to be little need of the technical 

 description which Mr. Beckwith gives. 



In Bulletin Xo. 18t Mr. Beckwith treats of the Strawberry Weevil 

 on pages 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 Ne'w Jersey Experiment Station. — In 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 

 Acridiidtv, but by Locustidic, and probably by one or two species 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 orickets, 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-
