48 THE ENTOMOLOGIST. 



this kind occurred to me a few years ago, when I had reared 

 fifty-seven larvae of Tseniocanipa Populeti from the egg ; they 

 were about half-grown, had spun the leaves of poplar together, 

 and were feeding between them : all went well for a lime, but 

 at length I observed spots of moisture between the withered 

 leaves, and, being puzzled at not finding any larvae in the 

 food that was removed, an investigation took place, when I 

 could discover no Populeti larvae, but an ill-looking n)onster 

 of a Satellitia coiled up at the bottom of the jar. This mon- 

 ster had actually murdered fifiy-seven of his fellow-prisoners, 

 and devoured their bodies." I could not find that my own 

 caplives ate any of the oak-leaves provided for them, but 

 feasted on juvenile Brumarias and such small deer, until I 

 expelled them from the breeding-cage. These larvae are so 

 decidedly cannibalistic in their propensities, that in default 

 of aliens they will devour their own species. When half or 

 three-qnaiters grown this larva is excessively active, and 

 very persistent in its endeavours to escape observation, 

 crawling with great activity, and often wriggling backwards 

 out of its retreat, after the manner of a Tortrix : the head is 

 porrected in crawling, rounded on the crown, and decidedly 

 narrower than the body: the body is nearly cylindrical, but the 

 anterior segments are attenuated. Colour of the head clear 

 bright brown on the crown, black-brown about the mouth : 

 body rich velvety brown ; the '2nd segment has three paler 

 longitudinal lines on the back ; of these the middle one is 

 less distinctly pronounced than the other two : these appear 

 like the anterior extremities of three dorsal stripes, the 

 remaining portion of which has been obliterated in the 

 greater number of specimens, but which are slightly indi- 

 cated in some throughout the entire length of the body : on 

 a line with the spiracles there is present, between the 2nd 

 and 3rd segments, and again between the 3rd and 4tli seg- 

 ments, a somewhat linear but inconstant snow-white spot; a 

 linear white spot on the 5th and another on the 11 ih seg- 

 ment; these seem like broken portions of a spiracular line 

 which is very evident in souie specimens, but scarcely per- 

 ceptible in others : ventral surface, legs and claspers paler 

 and less velvety than the dorsal surface; legs variegated 

 with black. From Guenee we learn that this larva, when ap- 

 proaching its full size, descends from its exalted station
