The larvae pupate early in June or late in May. The adults 

 emerge about September. Hibernation probably takes place in the 

 larval stage, but the length of the egg, larval, and hibernation 

 stages is not yet known.

 Potatoes. — Jl. Econ. Eniom., Concord, N H., xiii, no. 1, February

In Louisiana considerable damage caused to sweet potato was 

 attributed to the sweet potato weevil {Cylas formicarius), but was also 

 due to some extent to the Scolytids, Xylehorinus pecanis and Plafypus 

 composilus. The burrows of the former are clean cut, those of the 

 latter filled with some material. Trees or newly cleared land were 

 always present near the infested fields.

Adults and nymphs of the bug, Anasa iristis, were observed in 

 considerable numbers in August on fig trees in Louisiana, no cucurbit 

 vines being within one hundred 3'ards. 



Smyth (E. G.). To keep out Cane Butterfly. — Jl. Econ. Eniom., 

 Concord, N.H., xiii, no. 1, February 1920, p. 149. [Received 

 13th April 1920.] 



Attempts have been made in Porto Rico to secure permission to 

 introrhice seed sugar-cane from San Domingo, in the hope of over- 

 coming the mosaic disease of sugar-cane. There would however, have 

 been great risk of introducing also the butterfly, Calislo archebates, 

 which would have been an irreparable calamity in Porto Rico, where 

 already May beetles [Lachnos'erna'] and Diaprepes spengleri cause 

 great loss to sugar-cane. 



There are no regulations. Federal or Insular, that could be utilised 

 to keep out this cane ; but the idea was given up under pressure from 

 the quarantine experts of the Insular Experiment Station in favour 

 of the cultural methods of combating the disease that they advised.

 in South Carolina and Florida. — Jl. Econ. En' am,., Concord, N.H.,

 1920.] 



The Porto Rico mole-cricket {Scap'eriscus vicinus, Scud.), for a 

 number of years a troublesome pest in Georgia, has recently re- 

 appeared in South Carolina and Florida, where it had been noticed in 

 1915 and 1917. 



In August 1919 it damaged the fairways and greens of the Florida 

 County Golf Club. Carbon bisulphide and lead arsenate were un- 

 successful against it, but poisoned baits, hke those used for cutworms, 

 were very effective.
