58 THE REPORT OF THE No. 19 



41. Lithocolleti'< tiliacellu, Chambers. This is another miner in the leaves. We have 

 found the species rather plentiful at Ottawa some seasons. Regarding this and the preceding 

 species, Mr. August Busck, of the Depaitment of Agriculture, Washington, tells me, in corres- 

 pondence, that these two small white and golden moths are much alike, to the uninitiated, in 

 their adult stage, but can be easily recognized by anyone by their different mines. Lncetiella 

 makes an inconspicuous small, white, tentiform mine between two ribs, on the underside of 

 the leaf, while tUiacelki makes a larger, showy, nearly circular white, brown-dotted blotchmine 

 on the upper side of the leaf. 



42. Paronjiiia Clintoidi, G. & R. Specimens of the larva of this moth have been found 

 feeding on basswood by Mr. C. H. Young, at Meech Lake, Que. The larvie were full grown 

 in July, and moths from collected material emerged the end of August. 



43. Heterocampa manteo, Dbl. Full grown larva? of this notodontian have also been 

 found on the linden at Meech Lake, Que. by Mr. Young. Caterpillars collected the end of 

 August produced moths the'later half of the following June. Some of the larvte gathered 

 were parasitized by the large ichneumonid, Ophion bilineatus. 



44. Symmirista albifruns, S. & A. The caterpillars of tnis moth have been recorded by 

 Dr. Fletcher as having appeared in great numbers at Ottawa in 1884, being particularly 

 injurious to oaks and maples. Larvre about half grown were found feeding on ba.sswc od on 

 the 15th August, near Ottawa, by the writer. 



45. Tortricidia testacea, Pack. A larva of this species was found feeding on the foliage by 

 Mr. Young, and another specimen by the writer, the moths emerging in June. 



46. Euclea qnerceti, H.-S. Mr. Young tells me that larvfe of this pretty little moth 

 were very common on basswood at Meech Lake, Que., the past season. Full grown cater- 

 pillars were collected in September. The moth appears in July, specimens having been col- 

 lected on the 12th, 14th and 27th. 



47. The Pyramidal Grape-vine Caterpillar, PyrophUa pyramidoides, Gn. A few examples 

 of nearly full grown larvpe of this common insect, have been occasionally beaten from bass- 

 wood, about the middle of June, at Ottawa. The caterpillar is frequently destructive to grape, 

 but while partial to that plant, it also feeds on maple, plum, poplar, gooseberry, etc. 



48. Mefrocampn priearandaria, Gn. This species occurs throughout Canada, and in some 

 districts is fairly abundant. We have found the larviB on basswood at Ottawa, the moths 

 emerging early in September. The imagos fly at Ottawa the latter half of June and again 

 late in August. 



4*^. Cenopis Pettitana, Rob. On the 31st May, 1899, the writer collected the larva of this 

 small tortricine moth on the foliage of basswood. The caterpillar changed to pupa on the 7th 

 June, and the moth emerged on the 16th June. 



Other lepidopterous insects which have been recorded as feeding on basswood, and all 

 of which occur in Canada, are as follows : — 



50. Papilio tiirnus, L. 58. Badlona imperialism Dru. 



51. Polygonia interrogationis, Fab. 59. Panthea furcilla , Pack. 



52. Polygoni((. comma, Harr. 60. Apatela hastnlifera, S. & A. 



53. Busilarchia arthemis, L. 61. Ajxiteln morula, Grt. 



54. Envanensa antiopa, L. 62. Apatela luieicoma, G. & R. 



55. CenUomia amyiitor, Ceyer. 63. Datana Aiujusii, G. it R. 



56. Pliobetron pilherAtim, ^. & A.. 64. Datana DrexeUi, Hy. Edw. 



57. Samia cecropia, L. 65. Lithacodes fasciola, H.-S. 



During our study of the insects which feed upon the foliage, we have collected at least a 

 dozen more species of lepidopterous larv;w which we have been unsuccessful in rearing to the 

 imagos. The mijority of these were small species.
