Note A, [p. 270.]—The Trap-doors drawn at [Figs. 117], [118] and [121] are from Moggridge, and are not of American species, though they differ only in size.
Note B, [p. 271.]—This habit has been attributed to the Trap-door makers, but needs to be confirmed.
Note C, [p. 275.]—The mother wasp, which lances and paralyzes the big southwestern Tarantula, Eurypelma Hentzii, is Pepsis formosa, called popularly the "Tarantula hawk." The author has seen it pursuing the above species, but does not know positively that it attacks the true Trap-door maker, Cteniza Californica.
Note A, [p. 280.]—This is no doubt a true representation; see the three claw marks on the inside of the lid shown at [Fig. 124].
Note B, [p. 284.]—The moulting period (see next Chapter), is attended with great weakness.
Note A, [p. 290.]—The sting of the spider collecting wasps destroys the power of motion, but does not at once kill; it is certainly fatal in the end, if the young wasp larva does not in the meantime eat the victim stored away for her by maternal foresight.
