28 THE CANADIAN ENTOMOLOGIST. 



constructs a burrow branching out semi-horizontally from the 

 original one, commencing about two inches below the surface and 

 having an average length of nine inches, though some I examined 

 extended for eleven. The burrows slant downwards to a depth of 

 five inches from the surface at their extremity. Here in an 

 enlarged chamber the pupa develops, and afterwards the beetle. 

 The adult of C. lepida appears toward the end of June and is as 

 perfect as can well be in its colour resemblance to the sand. It is 

 a very weak flier, due doubtless to its being far safer on the sand 

 in its deceiving dress than it ever would be in an attempt to 

 escape by flight. 



Lepidoptera are not very much in evidence here in June, but 

 there are a few prizes well worth scouting for. Should we venture 

 to the edge near the swamp we should probably see several 

 butterflies not strictly belonging to the sand, such as our old friend 

 (Eneis jiUta, common enough farther in. Returning to the drier 

 sand we may with good luck sea a great rarity called Copihlepharon 

 convexipennis , though I have no records before July. This species 

 is generally at rest on the sand and unless one is very carefully 

 on the lookout — for it is another sand colour mimic — it will have 

 departed almost before we are aware of its presence. 



Among the spreading shoots of Sallx longifolia may be found 

 a sandy-coloured cutworm, probably Agrotis aiirulenta. Its work 

 is plain enough to see, but it prefers as a resting place the cool 

 moist sand, and may, therefore, be several inches below the surface. 



Another moth very rare at this time, but common a month 

 later, is Pseudotamila aivemensis Dyar, found as yet nowhere else. 

 Its fore-wings, like so many other creatures found here, resembles 

 t'le sand, but the secondaries are pure black. It may be found 

 throughout July resting on the sand, or more often on the flowers 

 of Skeleton Weed, Lygodesmia juncea. 



Among Orthoptera various species of grasshoppers are in evi- 

 dence, chiefly, however as nymphs. Hippiscus latifasciatus is com- 

 mon, as elsewhere, but to my eye looking rather paler than its 

 brethren of the prairies, as if there were an attempt to harmonize 

 just a little with the sand. Hippiscus neglectus turns up on the edges 

 of our tree islands or upon the borders of the sand in small numbers.
