parchment texture. In the meantime I had sent to Dr. H. G. Dyar 

 some of the larvee for examination and identification. He wrote me 

 that they were evidently highly specialized Tineids and of much inter- 

 est, and expressed his hope that I would raise the moth. In a little less 

 than four weeks from the time the cocoons were made the moths ap- 

 peared. I at once recognized them as Mieza ignbiix Walk., the Eim- 

 viia crassinervella of Smith's check-list. This dainty little creature, 

 with primaries of silvery white, striped and dotted with black and sec- 

 ondaries of vivid rose color, is not uncommon at Punta Gorda, and I 

 had taken it several times this season resting on leaves near the spot 

 where I found the larvae. Dr. Dyar will publish a full description of 

 the larva, with notes. 



A DESCRIPTION OF THE -LARVA FOUND BY MRS. SLOSSON. 

 By H.A.RRISON G. Dyar, Ph. D. 



Considerable interest attaches to Mrs. Slosson's discovery of the 

 larva of Encemia crassinervella, since in it we find an exposed feeding 

 Tineid. These are always of interest, for as soon as the Tineids aban- 

 don their concealed mode of life numerous specializations occur, and 

 usually in the direction of some higher family of the group — the super- 

 family Tineides. I was able recently to describe a Tineid (^Butalis 

 basilar is Zell), which had assumed many characters of the Pterophoridae, 

 and now I shall describe the present species with strong tendencies 

 toward the Eucleidce, yet without losing its essential Tineid characters. 



Larva. — Flattened, thick, head partially retractile, but large, 

 joint 12 slightly enlarged dorsally ; shape of Harrisina, but more flex- 

 ible, suggesting the Eucleidce by the soft, subventral region ; feet very 

 soft, short, of the normal number. Setae single, except a few irregularly 

 distributed secondary setce, or rather reduplications cf the primary ones, 

 short, stiff, glandular tipped. Setee i and ii approximate, in line trans- 

 versely, a secondary seta adjacent to i or ii or both, irregular in posi- 

 tion. Seta iii single ; iv and v approximate, yet by no means consoli- 

 dated ; iv a little above v, with or without a secondary seta below and 

 behind it ; vi double ; two setae on the leg. Joints 3 and 4 with both 

 primary and sub-primary setce, a secondary seta near ia and ib and 

 near iia and iib on joint 4, but variable. Seta iii seems absent on 

 joint 4, though present on 3. Cervical shield large, black, with six
