The egg shells when empty are very thin, but they reflect a brilliant blue light which attracts the eye more readily than the insect itself, and leads to its discovery in chinks and corners where we might not otherwise detect its presence.

Laboulbene (loc. cit.)has described this species as very closely allied to the preceding; but the woodcut shows that in the armature of the palpi it differs considerably from it. Three specimens of it were found in the pus which flowed from an abscess in the ear of a naval officer, consequent on an inflammation of the auditory passage. It was near the Bank of Newfoundland that the incident happened, but where the Cheyleti may originally have come from does not appear, nor how they reached their singular destination. Koch, in his Deutschlands Crustaceen, has described four other species of Cheyletus. Ch. casalis, which he regards as being probably a variety of eruditus, Ch. venustissimus, Ch. hirundinis, and Ch.
