resembles the common American Leptostylus macula, Say. The only 

 other Longicorn beetle recorded as infesting leguminous plants is 

 Baryssinus leguminicola, Linell, a single individual of which was taken 

 from a jar containing pods of Enferolobium, from Paraguay.

This paper is the first of a series on North American sawfly larvae. 

 Five species representing four genera of Gephids are here dealt with, 

 with a key differentiating the larvae. Aclirus trimaculatus. Say, is 

 recorded as boring in blackberries and roses. Janus abbreviatus, Say,, 

 infests willow and poplar ; from the material collected, Tetrastichus 

 sp., Euryfoma sp. and Microbracon sp. emerged. J. integer, Norton,, 

 agreeing with the larval description of J. abbreviatus, was found 

 boring in Ribes sp. (currant) in Massachusetts ; during the rearing 

 experiments, three undetermined Chalcids emerged. Cephus cinctus, 

 Norton, was obtained from Elymus canadensis ; and Hartigia cressoni,. 

 Kirby, from Rubus in California.

Adoretus umbrosus (Japanese beetle) is one of the most important 

 insect pests of grapes, particularly in restricted areas. As the beetles 

 hide under the soil during the day, hand-picking of the adults at night 

 when the insects can be seen on the foliage by means of a lantern 

 has proved the most effective measure, though it is tedious and 

 expensive. Experiments with arsenical sprays on grape-vines gave 

 good results ; 1 lb. paste lead arsenate in a very adhesive form to 

 10 U.S. gals, water proved the best of several formulae tried. During 

 wet weather a fungus disease was a factor of some importance in 

 controlling this beetle. Dacus cucurbitae (melon fly) is a great menace 

 to tomato growing in Hawaii ; it is hoped by hybridisation to secure a 

 strain resistant to the pest. A mite is found associated with a very 

 prevalent and destructive disease of potatoes, the new terminal 

 growth and the petioles becoming withered and dried, and the plants 

 dying in 10 to 20 days if seriously attacked. Whether the mites 

 are actually the cause of the disease is not known. Peregrinus maidis 

 (corn leaf-hopper) caused great destruction in a field of maize grown 

 for variety and fertihser tests. A large number of parasites 

 {Ootetrastichus sp.) were released among the maize and succeeded in 

 controlling the leaf-hoppers sufiiciently for a crop to be obtained.

The sweet potato {Ipomoea batatas) is becoming every year a more 

 important article of food in New Zealand, partly no doubt on account 

 of the failure of much of the potato crop during the past three seasons.
