THE CANADIAN ENTOMOLOGIST. 



I failed to determine whether the (^ 's had died a natural death, or had 

 been butchered by their wives. I had not noticed this cannibalistic 

 habit before, but this may account for the many fragments of this species 

 always common towards the fall season. I have often noticed the canni- 

 balistic habit of the larvae of Pyrameis carditis and other butterflies while 

 feeding in captivity. I never knew them to kill each other, but if one 

 got injured so that the bioplasm flowed out, the others seemed to relish 

 it very much, and continued to feed on it until completely exhausted.

NOTE ON AMBLYOPONE PALLIPES, HALD. 



In 1885 among material sent to Abbe Provancher was a curious ant, 

 of which two examples had been for some time in my collection, obtained 

 apparently by moss-sifting. The Abbe' expressed astonishment at the 

 occurrence of such a species in Canada, stating that it belonged to the 

 genus Amb/yopone, and that it would be the type of a new species which 

 he proposed to call A. canadensis. He subsequently (Add. Faun. Hym., 

 p. 240) described it as the worker of A. binodosits, believing it to belong 

 to the same species as a male formerly described by him (Nat. Can., 

 XII., p. 205), as a braconid under the name Arotropus binodosus.* 

 During subsequent seasons I searched carefully for this species without 

 success, and almost despaired of determining its habitat. This season, 

 however, I have been more fortunate, and on the 19th April was much 

 pleased at finding one worker under a stone about two miles west of the 

 city. A few days later — 30th April — on the opposite side of the Ottawa, 

 near Hull, I found in a rotten log a colony composed of several workers 

 and about a dozen larvae. Consigning four adults to my killing-bottle, I 

 placed the larvae and their remaining guardians in a box with a quantity 

 of the damp, rotten wood in which they were found. A vigorous search 

 in the vicinity resulted in the discovery of two similar colonies in another 

 log, which were also taken. Should I not succeed in obtaining females 

 and males from the larvae then obtained, I will hope to do so by search- 

 ing in June in the same locality. The ants are very slow in their move- 

 ments, and walk with the quadrate flat head held horizontally, and with 

 the long mandibles open, thus seeming much larger than killed specimens, 

 in which the head is deflexed. The larva? resemble those of Myrmica, 

 but are not so pubescent as the only species, M. kevinodis, Nyl., of which 



* Cresson in his list refers Arotropus binodosus to the genus Ponera.
