OF WASHINGTON. 465 



Sarasota plumigerella Hulst. Dr. Hulst's type was bred 

 from a larva on Laguncularia racemosa in a soft web only in 

 the young opening leaves, solitary. 



Head rounded, clypeus high, apex under joint 2, held flat, mouth pro 

 jecting; width i.i mm. Green mottled with brown, especially above. 

 Body slender, cylindrical, scarcely tapering, no shields Dull green, 

 opaque, mottled with brown, heaviest in a broad, obscurely double lateral 

 band below tubercle ii and just covering iii; a narrow brown dorsal line 

 edged by addorsal lines of the ground color. Subventrally the brown 

 mottlings fade out; feet green. A black ring about tubercle ii on joint 3. 

 Tubercles black, setae long, pale brownish. Segments divided into two 

 annulets by a narrow line with a third smaller one laterally. Tubercles i 

 and ii in line, iv and v closely approximate but separate, v dorsad by its 

 own diameter and a little smaller; on thorax ia and ib closely approxi 

 mate ia small. Spiracles round, yellowish. Cervical shield perfectly con- 

 colorous, bearing six setae, normal. 



To this list Mrs. Slosson adds Pilocrocis ramentalis Led., 

 Agriphila perstrialis Hbn., and Melitara prodenialis Walk. 



THYRIDID^E. 



Hexeris enhydris Grote. This was taken by Mrs. Slosson. 



NOLID^E. 



Nola apera Druce (involuta Dyar). Bred specimens cannot be 

 distinguished from the Californian species, except by a slightly 

 darker, more bluish gray color. This is very surprising, as the 

 larvae had all the appearances of representing a distinct spe 

 cies, being found only on the Laguncularia racemosa, a plant 

 growing only on the borders of the lake, partly in the water. 

 The larvaB are at first leaf miners with a hole for the ejection of the 

 frass. Later they cut channels in the thick leaves.' At all times 

 they hide persistently. This seems different from the willow 

 feeding Californian species, yet neither larva nor moth differ to 

 a specific degree. If the contrary opinion should obtain, how 

 ever, I would propose to call the form Nola laguncularice. 



Larva. Squarely flattened ; four rows of warts, the lowest small; feet 

 on joints 8 to 10, all normal for Nola. Head round, small, below joint 2, 

 clypeus broadly triangular, rather high, whitish, nearly colorless, jaws 

 brown, ocelli black; width, about .8 mm. Body reddish luteous, joints 3 

 and 4 somewhat broadly soon dorsum. A broad black subdorsal stripe, 

 faint on joint 2, narrow on 3 and 4, wide on 5 to 12, where it ends, cover 

 ing the two upper warts. In the incisure of joints 6 and 7 and 12 the pair 

 nearly join. A narrow yellowish dorsal line of the ground color; a red 

 dish circle on joints 3 and 4, somewhat broken. Sides reddish, but the 

 hird wart (iv-f-v) yellow. Feet and venter whitish, nearly colorless.
