NOTE ON AN INJURIOUS SAW-FLY LARVA. 



BY THE REV. THOS. W. FYLES, SOUTH QUEBEC. 



Length of larva, one and one-eighth inches ; breadth at widest part, 

 three-sixteenths of an inch. The body flattened beneath, and slightly 

 rounded above. It is scalloped along the sides. The legs proper are 

 long and projecting. The creature has the habit of twisting the last four 

 or five segments to one side. When disturbed it throws itself into the 

 usual attitude of a Nematus larva. Its general color is yellow — the 

 head has an orange tinge. There are ten rows of black spots on the 

 body — six rows along the back, one row on each side, and two rows 

 underneath. The spots of the side rows are longer than the rest, and 

 are placed one on the fore part of each scallop. In each of the rows on 

 the back the spots run three to a segment. The last segment has no 

 spots. The eyes of the larva are black, and the mandibles are brown. 

 The creature forms a rather loose, white cocoon. 



Swarms or this kind of larva fed on the white birch, in the neighbor- 

 hood of Quebec, during the month of September. They have all now 

 gone into the cocoon stage.

The earliest species which I noted during the past season, was the 

 common and obnoxious currant saw-fly, Nematus vejitricosus, which 

 appeared on 15th May. Two days later I captured upon willow in bloom 

 a specimen of Dolerus collar is, and on the 21st and 22 nd found D. aprilis 

 quite common on and about alders, with a few D. sericeus ? and D. ab- 

 dominalis. By the 24th May the strawberry saw-fly, Emphytus fnaculatus, 

 and the raspberry saw-fly, Selandria rubi, were in considerable numbers, I 

 and at the same time appeared several less well known species in fields I 

 and woods, such as Hylotonia McCleayi. This species I found again on 

 2nd June and subsequent days, upon the flowers of choke-cherry. Later 

 in the season specimens were found upon Spiraea. Selandria flavipes 

 was captured on loth June, and was abundant during the season. It
