iwo s'n.ilar [losterior ones and two \cry niinutt' ones silualed one posteriorly 

 end one anteriorh'. Tubercle III bears two long black setae and one or two 

 short white hairs. Behind the spiracle on the posterior margin of the segment 

 is a minute white hair. Tubercle I\' + \' bears five long central white hairs 

 and about the same number of shorter ones arranged as a rosette around the 

 central hairs; two short white hairs directed backward are found posterior to 

 this tubercle; \"I is very similar in arrangement of seta" to I\'-l-\ and \'1I is as 

 usual represented by several hairs at base of prolegs. On the prothorax a fringe 

 of white hairs overhangs the head; behind this is a row of five black hairs and 

 behind this row again are six black hairs arising from three tubercles, the middle 

 one of which is centro-dorsal. On the meso- and metathoracic segments tubercle 

 I-f II bears five long black hairs, and two or three short anterior white ones; 

 posterior to this group are two short white hairs arising from a small tubercle; 

 tubercle III has two long black hairs and several shorter white ones. Length 

 1 3 mm. 



Dr. Dyar's statement (Psyche, Mil, p. 250) that ^z//>a/om larv?e feed on 

 the underside of the leaf, concealed, whereas ellioiti larvae feed exposed on the 

 upper side, was not verified by my observations; both species may be taken on 

 either the upper or underside of the leaf, a favourite place being among the 

 terminal half-opened leaf-buds. 



Pupa (Fig. 4). — Apple green with purple-red suffusion each side of a pale 

 centro-dorsal stripe; the lateral portions below the subdorsal ridge prominently 

 purple-red with two oblique pale lateral lines and a similar spiracular one. 

 Subdorsal and subspiracular flanges well-developed. Wing sheaths with lateral 

 fringe of hair and further rows of short hair along the antennal and leg sheaths 

 as in elUoUi. Tubercles I and II on abdominal segments each with five or six 

 finely spiculate white hairs, arranged more or less longitudinally, the central 

 hair being longest. Dorsad to tubercle II is a single minute hair; on the first 

 three abdominal segments dorsally is a small tuft of short hair anterior to tubercle 

 I. Tubercle III, situated on anterior portion of the lower lateral stripe, bears 

 only a single short white seta ; posterior to it are two short hairs near rear portion 

 of segment and arranged in line parallel to the segmental incision. Tubercle 

 I\' + \', situated on the lateral fiange, is prominent, with about twelve long white 

 spiculate hairs, and immediately anterior to it and close to the spiracle are two 

 minute hairs arising from a small tubercle. Tubercles \T and VII are each 

 represented by a couple of short hairs. The thoracic segments show the usual 

 modifications in respect to the number of tubercular setae. 



THE HOUSE CENTIPEDE IN CANADA. 



With reference to the records of the House Centipede in Canada, pub- 

 lished in Can. Ent., \'ol. LII, p. 8, the following may be of interest. While 

 li\ing on King St., in London, Ont., we had occasion to renovate a part of the 

 house which had been used as a "back kitchen." This brought to light speci- 

 mens of the House Centipede in large numbers, and I killed more than a hundred 

 of them. Some were pinned in a box and show-n to Dr. Bethune, the rooms of 

 the Entomological Society at that time being in London. No special notes were 

 made as the occurrence was not thought to be unusual.
