210 THE CANADIAN ENTOMOLOGIST. 



Hemiptera. The chief collecting grounds are about two miles from 

 the railroad station and the vegetation consists mainly of pine, scrub 

 oak and along the roads, maple trees, and the weeds and shrubs 

 common to this latitude. 



Toward the end of September, 191 1. I had the good fortune to 

 spend three days there with Mr. G. B. Kngelhardt, who was guide, 

 philosopher and friend. We arrived about 11 a.m. the morning of 

 the 23rd, and indulged in a little collecting before the noon-day meal, 

 after which we went out and did some sweeping and beating witli 

 good results, one being the capture of a new Corizus, described else- 

 where. In the evening, between 8 and 10, Engelhardt went sugaring, 

 carrying a trap lantern, while I swept. The following day was rainy 

 in the morning, but as soon as it cleared up sufficiently we took 

 our way to the Carman River, a clear, shallow stream flowing over 

 a bed of sand where a litile dredging was done, which yielded 

 among other things one specimen of Belostoma lutaiium Stal. (taken 

 by Engelhaidt), which is the farthest Northern authentic record 

 for the species known to me. In the afternoon sweeping and 

 beating made up the programme, in the brush and trees about 

 a cranberry bog and in the grasses growing in it. Night sweeping 

 gave good result.=, no less tlian 16 species being taken in clearings 

 in the woods while Ozophora pidurata Say flew to light, its great 

 agility making it hard to catch. The morning of the 25ih dawned 

 grey and muggy, the day finally clearing in the late afternoon. 

 Sunshine or rain beintr one to the waterbugs, Engelhardt and I 

 betook ourselves to the Like, where wingless Rhetimatobaies rikyi 

 Bergr. was far from unconnnon, but only one Trepobates pictus H. S. 

 was seen, although I was out in a boat looking for it. Here, in the 

 floating duck-weed and algaj I secured what seems to be a new 

 species of Microvelia, in goodly numbers. On the way to and from 

 the lake sweeping and beating were done with good results, and this 

 part of the programme repeated in the afternoon yielded among other 

 things, no less than 1 1 specimens of the new Corizus, 2 being fully 

 winged, the other brachypterous. In the evening our stay was wound 

 up by Engelhardt visiting his sugared trees, while I watched the trap 

 light and caught two Ozophora. Altogetlier, in the three days, in 

 s(>ite of unfavourable weather, we got between us some 300 specimens 

 and 82 species of Hemiptera. The identified species are listed here-
