144 THE CANADIAN ENTOMOLOGIST. 



I first came across this interesting little cricket on Sept. 21, 1895, 

 when I found two specimens on the borders of a small pool near the 

 Humber River. The pool was on sandy soil, and supported a large num- 

 ber of aquatic insects and other animals. Since then I have taken it at 

 several different localities near Toronto, usually on the sandy margins of 

 streams. On June 25, 1901, I found it in considerable numbers on a 

 certain part of the margin of a small stream near York Mills, Ont., a few 

 miles north of Toronto. Here they were to be found upon the damp sand 

 a few yards from the water's edge, and when approached would leap 

 vigorously. They never flew more than a fevv yards, however, and were 

 fairly easily " marked down " on account of the bareness of the sand. 

 They were often seen peeping from their burrows, into which they would 

 immediately retreat on being approached. 



The spot where these crickets were found extended only some 15 or 

 20 yards along the margin of the stream, and although the banks were 

 explored for half a mile or more, and many other spots of similar charac- 

 ter passed, no more specimens of the insect were seen. 



(To be continued.) 



The notes on " Spring Methods of Telea Polyphemus,'' in the April, 

 1904, number of Canadian Entomologist, were very interesting, and 

 recalled to my mind a cocoon of this insect sent me from South Carolina 

 in 1899, securely fastened to a twig by a silk wrapping running up the 

 twig, after the same manner as cynthia and promethea. Among the 

 many cocoons oi polyphemus taken in various parts of New Hampshire, I 

 never saw one suspended in this manner, and had hitherto supposed my 

 Carolina specimens to be entirely exceptional. Mr. Cockle's suggestion, 

 that the habit of suspending the cocoon may have a relation to the 

 climatic conditions and be of advantage in regions where there is no 

 continuous snow-carpet in winter, may be found to hold true. It would 

 be interesting to hear from other localities on this question.

LiTHOBii FROM CALIFORNIA : A CORRECTION. — In my paper on 

 " Lithobii from California and Oregon," published in the Proc. Phil. 

 Acad, for 1903, page 152, a peculiar transposition of part of the key to 

 species occurs, this having been overlooked in the reading of the proof. 

 The two species, Aztecus and Chumasafiiis, in the key are placed in 

 division a, of.series A, with forms having the coxal pores in several rows. 

 As is evident from the statements in the key itself, and from the descrip- 

 tions of Chuinasafius following it, these two species belong in series B, 

 division a, the coxal pores being in a single row. R. V. Chamberlin.
