674 THE BUTTERFLIES OF NEW ENGLAND. 



commensalism has been noted by Fritz Miiller (Nature, xv : 264) in South 

 America, in which a large spiny caterpillar was almost invariably found 

 accompanied by a small, hairy caterpillar, so small as to rest securely in 

 a transverse position across the back of its good-natured host, well con- 

 cealed among its spines ; in proof of its continued existence at this point, 

 the skin of the host Avas hardened beneath the tread of its little guest, so 

 as to have become distinctly more callous than in other parts. Just what 

 advantage this would be to either party, both being feeders upon vegetable 

 matter, it would be difficult to say, excepting that the spinous surround- 

 ings might well be of assistance in protecting the smaller beast. But this 

 neat observation of Miiller seems to open a field of possible investigation 

 which may have great interest.

When the tangled cobweb pulls 



The cornflower's cap awry, 

 And the lilies tall lean over the wall 

 To bow to the butterfly. 

 It is July.

Imago (5:4, 10). Head covered with dull, brownish fulvous hairs and mingled 

 blackish and fulvous scales ; next the eye, just below and just above the antennae is a 

 little tuft of white hairs; the eyes bordered behind, broadly below, narrowing above, 

 with white scales. Basal joint of palpi white with a white fringe ; second joint pale 

 orange on the middle of the outside, growing deeper in tint apically, fringed above 

 and below with scales which are white on the lower half, changing to orange above, 

 and with a mixture of black and white and a few fulvous hairs along the whole lower 

 edge and on the apical half of the upper edge with orange hairs, mingled with black; 

 apical joint orange, tinged Avith broAvnish, Avith an intermingling of black scales above, 

 extreme tip black ; within, the basal joint is AvhoUy Avhite, the middle orange on the 

 loAver half, Avhite above; apical joint orange, Avith a fcAv black hairs. Antennae black 

 above; excepting a few of the basal joints, anuulated Avith Avhite at the base of the 

 joints of the stalk and of the base of the club ; beneath Avith a line of white exter- 

 nally, broadening upon the club, so as to occupy nearly the Avhole of its loAver surface ; 

 beneath, internally, yelloAvish broAvn, narroAved toAvard the apex of each joint, 

 broader on the club; four or five terminal joints of club dull orange, somewhat infus- 

 cated above and beloAV. Tongue luteous at base, beyond fuscous, the extreme tip 

 luteo-fuscous, with fuscous papillae (61 : 42), Avliich occupy only the extreme tapering 

 tip, are situated at the outer margin of the under surface (the basal ones a little inside 

 the margin), are about as long as the breadth of one maxilla, excluding the part form-
