88 THE REPOET OF THE No. 36 



way lies, grows a patch of raspberry canes, where I captured once in full flight, 

 with my hand, that most elusive of dodgers, the Oberea. On the leaves of these 

 raspberries one day I saw some tiny dark conical galls, as I supposed, and one of 

 these I tried to tear from the leaf ; to my surprise, when I partly wrenched it aside, 

 it distinctly moved and glued itself back on the leaf. This was something new for 

 a gall, and I pulled it away from its fastening to find that it contained a live larva 

 whose legs were kicking frantically to get back to the leaf. You have often seen 

 a refractory man-child plucked suddenly up by the nurse from the place where it 

 was playing? Well, that's how this caterpillar kicked. It was Ghlamys, one of 

 two genera that represent the fifth tribe. These insects construct a case out of 

 their own excretions and under cover of this tiny, steeple-crowned brownie's cap 

 of a case, they move about and feed securely; when the time comes to pupate, they 

 simply close the door at which they have grazed and behold, a ready-made cocoon. 

 The insect itself is dark brownish black and covered with little warty excrescences ; 

 when alarmed it closes its legs and falls to the ground, where it escapes notice 

 entirely or is passed over by warblers and other insectivorous birds as a pebble or 

 a pellet of dirt; one more instance of protective mimicry preserved in this creature 

 through all stages of its existence. 



On these same raspberry leaves is often found a small yellow beetle with a 

 black thorax ornamented by two white spots; it frequents many other leaves 

 besides such as basswood and hazel, but it is most abundant on raspberry. It is 

 Bassareus luieipennis, the first of seven genera that constitute Tribe VI. These 

 seven genera contain over 100 species, about fifty being found in Ontario. 

 Three of the genera, containing over 35 species are represented riglit in this wood. 

 Bassareus on the raspberry, Crypiocephalus quadrimaculatns (the size of the insect 

 as usual in inverse proportion to its same) on the young shoots of white pine where 

 the needles are soft, and Pachyhrachys on the willow shrubs at the lower end of 

 the wood. The members of this tribe are small, sometimes minute and stoutly 

 cylindrical in shape, what we would call " chunky " — indeed Pachyhrachys (the 

 Greek for "thick-short") is only a grand name for "chunky." Some of the 

 species of Crytocephalus (which means "hidden head") are very pretty, especially 

 vermstus which I have found on the blossom of the meadow-daisy, and mutabilis 

 taken on birch and spiraea. 



As we walk back to the road that we left at Mose Robinson's we can collect no 

 less than five genera of the next or seventh Tribe. In the hollow at the north-east 

 of the wood where the clump of willow and dogwood grows, you will find 

 Xanthoma on the leaves of the former and Adoxus on those of the latter; the first a 

 small and the second a medium-sized beetle, closely resembling each other in shape 

 and general color ; about the trunk and limbs of that newly felled pine on the bank, 

 (xlyptoscelis, a fairly large beetle, metallic brown in color but looking lighter from 

 it'; pubescence; on the common Dogbane (Apocynum androsaemifolmm) you will 

 find Chrysochus aureus, a large dazzlingly brilliant bluish-green beetle ; it is said 

 to feed on Indian hemp {Apocynum cannahinum.) and on Milkweed (Aselepim), 

 but I have never found it on any milkweed or on any other species of Dogbane 

 than the common, sweet-scented species with pinkish blossoms; Apocynum 

 cannahinum has greenish-white blossoms and no scent ; as the Dogbane is filled 

 with a white milky juice just as abundant as that of the Milkweed, Blatchley's 

 description may be erroneus; on the Dogwood, again, both leaves and blossom, a 

 fifth genus of this tribe {Colaspis) is often found .
