Zoology. 434 LEPIDOPTKRA SO highly adapted for the tasting of sweets that it is difficult to recognise in them the parts usually found in the maxilla of mandibulate Insects. Uriocephala in both these respects connects the Lepidoptera with Mandibulata: the mandibles have been shown by Walter^ to be fairly well developed ; and the maxillae are not developed into a proboscis, but have each two separate, differen- tiated—not elongated—lobes, and an elongate, five-jointed, very flexible palpus. The moths feed on pollen, and use their maxillae for the purpose, somewhat in the style we have men- tioned in Prodoxidae. The wings have no frenulum, neither have they any shoulder, and they probably function as separate organs instead of as a united pair on each .side : the modification of the anterior parts of the hind wing—whereby this wing is reduced as a flying agent to the condition of a subordinate to the front wing—does not here exist: the hind wing differs little from the front wing in consequence of the parts in front of the ceil being well developed. There is a small jugum. These characters have led Packard to suggest that the Eriocephalidae should be separated from all other Lepidoptera to form a distinct sub-Order, Lepidoptera Laciniata.^ The wing-characters of Uriocephala are repeated—as to their main features—in Hepialidae and Micropterygidae; but" both these groups differ from Eriocepluda as to the structure of the mouth-parts, and in their metamorphoses. Although Erio- cephala calthella is one of our most abundant moths, occur- ring in the spring nearly every- where, and being easily found on account of its habit of sit- ting in buttercup-flowers, yet its metamorphoses were till recently completely unknown. Dr. Chapman has, however, been able to give us some ^^"^ 209.—Larva of EHocephala calthella. p . Ill- (After Chaiiman.)
