THE CANADIAN ENTOMOLOGIST 



the species, was that the insects were again disclosed living at the top of a 

 maple tree. The two specimens were taken from under the bark of a short 

 thick branch, lately fallen, like the first broken top, from the summit of a 

 large maple in Elliott's sugar-bush. 



In each instance the conditions under which the insects were found 

 precluded any chance of their having made their way from the ground onto the 

 fallen piece after it had come down. They had certainly been living in the 

 tops of the trees. Of course, numerous Collembolans live all over trees from 

 root to crown wherever there may be a little moisture or rotten wood; but 

 this species appears to live in the tops only. However, I can see no good 

 reason why this should be their only habitat, and it is probable that eventually 

 they will be found in lowlier stations. 



As appropriate to their apparent predilection for high places, the species 

 is named "sublimis", the word — which was kindly suggested to me by Mr. F. 

 J. A. Morris of Peterborough — being used in iis primitive sense of "raised 

 up." 



The genus Friesea Dalla Torre comprises only five described specier, 

 including the subject of this paper. The discovery of the present species neces- 

 sitates a few changes in the generic description which should now read as 

 follows : 



Genus Friesea Dalla Torre 

 Eyes eight on each side as a rule ; five on each side in F. deccmociilata 

 Bonier. Postantennal organs absent. Antennae four-segmented. Mand- 

 ible without molar surface. Head of maxilla simple. Unguiculi absent. 

 Furcula short, weakly developed in most species ; well developed in some 

 species ; mucro hooklike. Anal spines three. Anal segment small ; supra- 

 anal valve rounded semi-globose. Body without segmental tubercles, 

 cuticula tuberculate. 



Friesea sublimis, n. &\i. 



Color, pale lilac on silvery white ground, the head being slightly darker 

 than the body; under parts lighter and body sutures white. Byes, (fig. 1) eight 

 on each side. No postantennal organ. Antennae (fig. 2) subconical, three- 

 quarters length of head; third and fourth segments confluent dorsally but suture 

 shows ventrally ; fourth segment with five or six thick curved olfactory setae 

 as well as many straight, tapering hairs; stout capitate protusible sense organ 

 in a deep pit on apex just inside median line, another sense organ of two thick 

 hooked members distally in a recess on outer side of third segment. Maxilla 

 (fig. 3) with simple head and acute apex. Mandible witii several distal inner 

 incisive teeth and no molar surface. Unguis (fig. 4) stout, curving, untoothed; 

 unguiculus represented by a rounded lobe only ; front feet usually with four 

 knobbed tenent hairs, and mid and hind feet with five such hairs, but sometimes 

 the hairs immediately above these are knobbed also making a total of six, seven 

 or eight tenent hairs; tibiotarsus with a distal subsegment. Furcnla (fig. 5) 

 not rudimentary, but short, not reaching to second abdominal segment; dentes 

 not reduced, stout, with three dorsal setae ; mucro one quarter length of dens, 

 with strong apical hook and prominent rounded lamella. Tenaculum bidentate.
