Note. 221 



Note. I had not an opportunity of examining a sufficient number of 

 specimens, of the common Lackey or Apple moth, which is so destruc- 

 tiye to the foliage of the trees round Montreal, to determine with 

 accuracy the species to which it belonged, until after my article on 

 " insects injuring the crops in the vicinity of Montreal " was in type. 

 Having lately compared recently captured specimens with the descrip- 

 tions in Dr. Fitch's reports, I have come to the conclusion that it is 

 Clisiocampa Sylvatica, (Harris) and not C. americana as previously stated. 

 The date of the article also was accidentally omitted. It was commu- 

 nicated to the Natural History Society, at its monthly meeting, June 

 29th. To enable non-entomologists to recognise that useful insect Calo- 

 soma calidum, I subjoin a short notice and discription of it. 



Calosoma Calidum. Seepage 163. 



This fine beetle belongs to the first division (Geodephaga) of the 

 order of Coleoptera. The geodephaga or carnivorous ground beetles 

 are so termed from their habit of living principally on the ground, and 

 feeding in all their stages on other insects. The division is divided into 

 two families. 1st. Cicindelidae or Tiger Beetles, several species of 

 which are very abundant about Montreal, flying in the sun on sandy 

 places ; and 2nd. Carabidae which includes all the other geodephagous 

 insects. There are a vast number of species in this country, all more or 

 less useful in keeping down the numbers of noxious insects ; but the 

 present, conspicuous from its large size and great strength, is the most 

 beneficial to us. The genus Calosoma to which it belongs contains 

 many large species and most are splendidly ornamented with metallic* 

 tints. A great number of the Carabidae are destitute of wings under the 

 elytra, but this species and the rest of its genus are amply provided with 

 the organs of flight, which enables them to follow their insect prey with 

 greater facility on trees as well as on the ground. Calosoma Calidum, 

 copper spot carab ; black, all the joints of the antennae except the 

 four basal ones clothed with piceous hairs ; sides of the thorax and 

 elytra minutely punctured ; the punctures green ; elytra deeply 

 punctate-striated, each with three rows of deep impressions, and one 

 or two (sometimes more) at the base near the suture, of a brilliant 

 copper colour. Length from ten to twelve lines. Professor Em- 

 mon's figure in his work on the Insects of New York is so bad that it is 

 impossible to identify it.
