fresh-water loriiis, his liouse ^\'as located and found to l)e close to 

 the woods and with trees, not a part of the original woodland ex- 

 tending well toward the porches. It was a situation which would 

 readily tempt the sylvan species, and accounts for the predomi- 

 nance of C. ahjitchii early in the season. ISTo dangerous puddlevS 

 were seen, though the grounds themselves were not examined, and 

 attention was directed to the sewers. Several of the covering plates 

 ■were lifted and l)eneath each was found a large settling bucket, full 

 to the brim of dirty water. Most of them had no wrigo-lers, but 

 some had, and directly in front of Mr, Renwick's house was a 

 bucket with an egg-boat and numerous larvae and pupa3. The local 

 supj)ly and recent occurrence of C. pipiens was thus readily ex- 

 plained, and attention was called to the matter. 



During the day, while driving, the horse was frequently covered 

 hy mosquitoes, almost all cmitator, and specimens of the same spe- 

 cies were taken on ]\ir, Itenwick's porch and in his garden. In the 

 evening, on a hotel porch, both C. cantator and C, pipiens were 

 taken — six of the former to one of the latter, but as there was con- 

 siderable wind, mosquitoes were less than usually troublesome, 



August 6th, breeding conditions from South mountain to Mill- 

 burn were unchanged, and only a single lot of wrigglers was found. 

 These were composed of six C. serratus, one C. sylvestris and one 

 Anopheles punctipenms. 



August 10th, Mr, Ronwick sent in his last lot of adults for the 

 season, composed of C. cantator, four ; C. sylvestris, four, and C. 

 cantans, two. This is the last appearance of C. cantans (more 

 probably ahfitcltii) in the collections, and indicates a possible 

 length of adult life of ten weeks — much longer than we had be- 

 lieved from previous experience, and that makes this single brooded 

 species a imu-h more serious pest than some other even more plenti- 

 ful but shorter-li\'ed species, 



August 18th, Mr. Brehme, in tracing out the course of brood 

 <5 from the Elizabeth marshes, covered the area from Springfield 

 to Summit; and found ninety sollicitans, two sylvestris and one 

 pipiens. On the South mountain the collections made were twenty- 

 one sylvestris, five cantator, fi^'e sollicitans, one canadensis, one 

 triseriatus. This was purely a tracer for adults and the search 

 was continued on the 20th. From Millburn to South Orange road, 

 seven' sollicitans, three cantator, four sylvestris, one triseriatus. 

 Soutb Orange road to St. Oloud, two sollicitans, two cantator, four
