230 THE CANADIAN ENTOMOLOGIST. 



On examining the can containing the cooked meat, I was surprised to 

 find in it seven specimens of Centhophilus maculatus, as I had not ex- 

 pected to trap Orthoptera. 



I visited the traps again on August 15th, but as there had been a 

 heavy thunder storm on the previous day, I met with poor success. The 

 trap which had yielded so abundantly on the 12th, now contained nothing 

 but water, but from the can with cooked bait I took 5 orhicoUis, 4 

 ve/uti/ia, i surinamefisis, and i StapJiyliiius lullosus. 



NOTES ON CHRYSOMELASCALARIS, Lee. 



BY F. B. CAULFIELD, MONTREAL, P. Q. 



In No. 7 of Entomologica Americana, Mr. G. W. J. Angell gives some 

 interesting notes on this insect. Having examined a large number from 

 various localities "showing a nearly complete gradual gradation from the 

 finely maculate form oi p/iiladeip/uca, to the strongly marked scalar is type," 

 Mr. Angell is of opinion \\v3X philadelphica Lin., midtipuncta?i2.y and its 

 supposed varieties, are all varieties o{ scalar is Lee. I incline myself to the 

 belief that scalaris and philadelphica are distinct species, and as my ex- 

 perience of these forms appears to be different to that of some other col 

 lectors, I give it in the hope that it may lead to a careful study of their 

 life habits. I find that Dr. Harris' history and figure oi scalaris fit it exact- 

 ly as it occurs in the neighborhood of Montreal. For years past I have 

 found it on elm and linden, and on no other plant or tree. Philadelphica 

 and Bigsbyana I find on willow and alder ; never on elm and linden. Dr. 

 Packard in his Guide states that scalaris is abundant on the alder. This 

 statement puzzled me, as I never yet have found a typical scalaris on 

 that shrub. In the Report of the Entomological Society of Ontario for 

 1882, Mr. W. H. Harrington states that scalaris is "found throughout the 

 season on various trees, as elm, the linden, and especially the willows and 

 alders. The same writer states that //^'/^z^/^'/^/^/V^ feeds on the leaves of 

 the pin-e. It would thus seem as if these insects varied their food plants 

 in different localities. It is now too late to do anything this sea- 

 son towards settling the question, but next year I trust it will be fully in- 

 vestigated; meanwhile I would like to hear the opinions of other collectprs,
