allied to that described above. Tliey (Utter in being a little 

 larger and more hairy. The ease is similar, though with a 

 rough exterior. The pupa (Fig. 014. a, antenna 1 , curved back 

 behind the eyes : /, labruni ; /it, mandibles ; nip, maxillary palpi ; 

 /c, wint>'s) of this Nicaraguan larva is curved in a slightly 

 spiral manner, the antenna? are curved over and behind the 

 eves, reaching to the seventh abdominal ring ; the maxillary 

 palpi are laid backwards on the side ol' the thorax, and the 

 labial palpi lie between them, though diverging from each 

 oilier. The wings are pressed to the body under the legs, 

 the latter being fringed with long hairs. On the end of the 

 abdomen are two slender tubercles ending in tine hairs, and 

 alike on both sides, the pupa, like the larva, being- symmetri- 

 cal throughout. The larva 1 seem to live in clear water on a 

 sandy bottom, often attached to submerged sticks, 

 unio shells, etc. 



In Leptowi'HS the antenna' ol' the nudes are ex- 

 tremely long; tibial spurs thus: 2, 2, 2. L. niycr 

 Linn, is black, shining, with black hair; the antenna' 

 are black, the basal half aimulated with snow-white, 

 while the basal joint is reddish ; the feet are luteous, 

 the intermediate ones being snow-white, while the 

 Flu. <;i.-.. anterior wings are steel-blue black, and the hind 

 wings blackish. It is found in Europe and the Tinted States. 

 Fig. 61 o represents, Dr. Hagen informs me. a case of either 

 this species or L. sepulchral Walker, or else a similar species. 

 The larva builds a thin, long, conical, sandy tube supported 

 between two needles of the pine. The specimens figured were 

 found by Rev. E. (A Bolles at West brook, Maine. 



In Xetodes the species are snow-white; the spurs are ar- 

 ranged thus : 0, '2, >. S. Candida Hagen is pale yellow, with 

 the anterior wings snowy white. It occurs in the Southern 

 States. McLachlan states that -'some species 

 of Setodes make delicate little tubes, entirely 

 formed of a silky secretion, without any mix- 

 Ki?r. en;. tiire of extraneous matters." Fig. 610 repre- 

 ts a tube of a European species of Setodes formed of sand. 

 In /l~f/<lr<>j>xi/t-he and allies the ocelli are three in number, or 

 entirely wanting, while the last division of the maxillary palpi
