HYMENOPTERA FHYTOPHAGA, 1893. 
By W. Hague Harrington. 
Since the publication of my catalogue of the phytophagous hymen- 
optera of this locality, I have been able to examine the insects of this 
group which were captured 'by me last summer, and the annexed list 
will serve as a record of the season's work, and, at the same time* as a 
supplement to the previous paper. My collecting was restricted to the 
month of June and the first two weeks of August, and even during 
these periods the unusual number of wet days limited my outings con- 
siderably. Sawflies also seemed to be much less abundant than in 
some seasons, and several even of the commonest species were not ob- 
served. It will be seen that there are only 42 species in the list, or 
only about one half of the number recorded (Canadian Entomologist, 
vol. xxii, page 23) as captured here in 1889." Quite a number of the 
specimens were secured at the sub-excursions to the Mer Bleue and 
Casselman, and I find that at the latter place a specimen was taken 
which proves to be an addition to the published list, viz. Monophadnus 
tilicF, which, as the name indicates, is known to occur upon the bass 
wood, in Canada and the United States, and of which the probable 
larvae have been observed by me on the trees of this locality. 
Trichiosoma triangulum Kirhy. 1 female, Aug. 13, Race-course. 
'/.area inflata, Norton. 1 female, July 31st. The occurence of a second 
specimen confirms this species which >vas doubtfully placed in 
former list. 
Hylotoma McLaiyi, Leach. 2 females, July 29, Hull, goldenrod. 
'' clavicor?iis, Fabr. 1 female, June 3, Mer Bleue ; 2 do , June 
14 ; 1 do. July 30, Hull. 
Nematus snbalbatus, Norton? 1 female. 
corniger, Norton. 2 males, June 10; 1 female, July 29. 
" erythrogaster, Norton. 1 female, June 7 ; 1 do. July ,50. Hull. 
" sp. near preceding. 1 female, June 6, Hull. 
Erichsonii, Hartig. Several females in tamarack swamp beyond 
Casselman on June 10th, Larvae less abundant in this district 
apparently than in former years. 
Nematus ribesii, Scop. Abundant as usual in gardens.
