worth considering. These facts give a valuable suggestion in the mat- 

 ter of preventives. 



BEMEDIES. 



Remedial measures are difficult and in general impractical, because 

 the larvii' and adults feed on all sorts of vegetation and are very widely 

 distributed. The adults, also, are too active and <[uick of flight to be 

 successfully reached by caustic washes; and spraying to destroy the 

 early stages is ordinarily out of the question, because it would necessi- 

 tate extending the treatment to all surrounding vegetation, and as the 

 adults are strong flyers, even this would give no absolute security. 

 We must therefore turn to ])reventive measures for practical results. 



Tlie limiting of the amount of foreign vegetation about and in 

 orchards and nurseries is an excellent ])recaution, and little damage 

 may be anticipated where the ground between the trees is kept clean 

 and constantly cultivated. The larva^ and pupa^ under these conditions 

 will be starved out. The orchard in which the writer first studied this 

 insect, and which was so thoroughly infested as to be seriously injured, 

 was one which had been neglected for a number of years and was full 

 of weeds and succulent undergrowth, furnishing conditions under 

 which an unusual multiplication of the Ceresa had taken place over a 

 number of years. Surrounding and better-kept orchards showed little, 

 if any, damage. 



Vigorous pruning in the fall or winter should be given trees which 

 have been cut up to any extent, and this with clean culture should 

 reduce the insect to small numbers. It is possible that something 

 could be done by planting trap plants between the rows of trees, such 

 as beans or other similar summer crops, which could be sprayed with 

 the stronger mixtures of the kerosene and soap enuilsion when the 

 larvjB became numerous or about the 1st of July, but the more practical 

 method is the cultural one already described. 



SUPPLEMENTARY NOTES ON THE STRAWBERRY WEEVIL, ITS HAB- 

 ITS, AND REMEDIES. 



By F. H. Chittenden. 



The strawberry weevil {Anthonomus signatus Say) appeared in inju- 

 rious numbers in the spring of 1893 and again in 1891 in many of the 

 same places that were infested in 1892, as reported in a previous arti- 

 cle by the writer in Insect Life (vol. v, pp. 168-170), and in a few 

 new localities. 



INFESTED LOCALITIES OP 1893-'94:. 



In Maryland the strawberry weevil was reported by Mr. Elon Beh- 

 rend at Seat Pleasant, Prince George County, where it was injurious dur- 

 ing the past two seasons. 'So injury had been noticed on Mr. Behrend's 

 farm in previous years, but great damage had been done on neighboring
