to secure any more until a few days ago. Previous to last year they were very 

 abundant, eating the foliage all off of many bushes. For several years I have tried to 

 rear them in a glass jar and succeeded in bringing out one tly by putting a piece of 

 partly decayed wood in the jar, which the larvae entered to change. 



An examination of the larvse April 8, 1886, showed that they had 

 not then changed to pupse ; the adults appeared from May 28 to 

 June 8. 



September 12, 1888, a number of saw-fly larvfe were received from 

 J. G. Barlow, Cadet, Mo., which in every respect were like those pre- 

 viously obtained from Mr. Crane. They were, however, found feeding 

 on the leaves of a wild grapevine, and also on Polygonum dumetoruni. 

 With us, however, they refused to feed on these plants, but wandered 

 incessantly about in the breeding cage. Flies were obtained August 4 

 and 9, 1889. 



Mr. Charles C. Beach of Hartford, Conn., wrote us in June last de- 

 scribing the habits of a peculiar spotted saw-fly larva found by him 

 burrowing into decayed wood on which he supposed they subsisted. 

 He had in the previous year sent specimens to Dr. A. S. Packard, who 

 was unable to identify tbtm, and who wanted additional material. In 

 the absence of Dr. Packard in Europe, however, he communicated with 

 us, and in compliance with our request forwarded us specimens of the 

 larvae and adults collected the present year, concerning which he 

 writes under date of August 7, 1889, as follows : 



I mailed you yesterday a package containing a number of the live larvae of the 

 saw-fly of which I wrote you last June ; also a small bottle with two of the mature 

 flies. Since the receipt of your letter of June 22 I have searched faithfully for 

 more of the adults, but only succeeded in netting the two which I have sent you in 

 4ilcohol. The colors have remained practically unchanged. In the box containing 

 the larvae you will see that most of the specimens are covered with a sort of white 

 bloom, if their journey has not caused it to be rubbed off. This at times, or rather in 

 some instances, is very abundant and continues through all the molts until after the 

 last change, which takes place prior to pupating, when they appear of a black and 

 yellow color and naked. I placed one such in the box with the others. At this stage 

 they are exceedingly restless, ceasing to eat and being found at times a long distance 

 from their food-plant. It is impossible to keep them in a bottle covered simply with 

 gauze as they bite through it, but placed in a bottle with a few bits of dead wood, 

 they make no attempt to escape, but proceed immediately to bore. I have some at 

 present boring, having reached their last molt. When they are well settled in their 

 winter habitat I will mail you some if you desire them. 



The imago is a very pretty and active little creature, readily eluding the net, fight- 

 ing and biting with vigor when captured. I do not know whether the two specimens 

 I inclosed are of one sex or not. 



The larvae of this saw-fly are reported by Mr. C. L. Marlatt to occur 

 not uncommonly at Manhattan, Kans., on Cornus sp. 



Mr. Jack was at first unable to rear the adults, but in the spring of 

 1889, having accidentally found the larvae burrowing in decaying wood 

 picked up near Cornus bushes, he succeeded about the first of June in 

 obtaining the perfect insects, the larvae having pupated within the bur-
