A coiuit of one sqiiare foot of normal gravel was made 

 at this time and showed the following: Twenty-eight living 

 pnpae of longicornis, two larvae of spinosa, one pupa of Tijnild 

 hcUa Lw., one large Tabanid larva; forty-seven cast impal 

 skins of hiiif/i((iniis. as well as most of the natural beetle asso- 

 ciates given in a later place. This infestation was merely 

 norii'al and many square rods of ground along the south liank 

 of Fall Creek wei'e in almost the same condition. One small 

 larva, almost certainly of this species and described hereinafter 

 as such, was found hut practically all of the larva? had passed 

 into the pupal stage; many of these jiupir were very pale and 

 feebly colored and evidently but newly transformed.

Xatiiral enemies of the pupa^ and the teneral imagoes were 

 found to be medium-sized black Lifcosid spiders which were 

 incyiiig on the weak, uncolored adults in numbers; dozens of 

 the spiders were noted with individuals of the crane-flies in 

 their grasp; these spiders when alarmed would run away very 

 lapidly but onl\ in exceptional cases would they release their 

 victims. .\ I'ew .ll(i(J sjiiders were also noted with Eriocera'. 

 A mound of L;ra\'el and sand containing iiian\- piipic and skins 

 was noteil showing ti'accs of a bird or mammal having prcved 

 iijion the pupa'.
