June, '12] FERNALD: INSECTS OF .MASSACHL SETTS 24/ 



reported as dying. An examination sliowed that they had been 

 nearly girdled, close to the ground, and full grown larvae, pupa? and 

 adults of Leptura zebra Oliv. were found in the burrows. 



For several years the elm-leaf miner, Kaliosysphinga ulnii Sund., 

 has been present in consideral^le abundance. Last year this insect 

 was less noticeable than in 1909, but during the past summer its 

 work on Camperdown and European elms has been very noticeable. 

 In many cases the parenchyma of all the leaves of the trees has been 

 almost entirely consumed and the trees have made little or no growth. 



Some facts which have l^een noted would seem to indicate that 

 there are two generations a year of this sawfly in ^Massachusetts. 



The work of the maple-leaf stem sawfly, Priophorus acericaulis 

 MacGill., was quite noticeable in some parts of the state last spring. 

 It had previously been noticed but has evidently become much more 

 abundant during the last year or two. 



A specimen of the roach, Panchlora hyalina Sauss., was taken near 

 Amherst in a field at least half a mile from the nearest store. It is 

 of course, to be presumed that it came in on some tropical fruit, but 

 it is evidently liable to fly some distance, and ma}' therefore be met 

 with almost anywhere. 



During June the members of an elementary class in Entomology 

 at the college, interested in collecting insects, obtained a trolley car 

 headlight with the requisite apparatus, and took it to a point where 

 the local car line passes through a densel}^ wooded area. There they 

 established connections with the feed wire of the line and used the 

 headlight to attract insects. The resulting catch included about 

 twenty Actias luna, several Telea polyphemus and Automeris io moths, 

 besides a large number of smaller Lepidoptera, in a little over an hour. 

 Several trials of this method gave extremely good results, and suggests 

 the possibility of using electricity at places where moths are most 

 abundant, when trolley lines are properly located for this purpose. 



On the 5th, 10th and 23d of June, blister beetles were received 

 from correspondents in Stockbridge and Williamstown which were 

 evidently of the genus Pomphopcva and which were kindly identified 

 by ;Mr. Charles Schaeffer of the Brooklyn Museum as Pomphopcva 

 sayi Lee. This insect has never before been received by the Exper- 

 iment Station, and the data sent with the insects were of such interest 

 as to be worthy of record. The Williamstown correspondent, under 

 date of June 5, writes: "On the mountain ash tree where thej^ were 

 found, there were about a quart." One of the Stockbridge corre- 

 spondents wrote, June 10: "Yesterday morning on entering my 

 garden I found that these beetles had taken possession of the place. 

 Everj^ flower stock had been eaten down and the iris and roses were
