100 Tineina of the Central United States. 



v/ays from the middle segments. Head very small, flattened, polished, 

 honey yellow; jaws edged with rose color. General color of the body 

 translucent golden yellow, immaculate. Incisions quite deep, two or 

 three fine hairs on each side of each segment. The mine is made quite 

 spacious by the wrinkling together of the under cuticle of the leaf. 

 The frass is collected in one end of the mine. The insect pupates 

 inside its mine, inclosed in a strong, white, roundish or oblong cocoon, 

 similar in appearence to, though not so dense as, the cocoon of Chrysopa. 

 The chrysalis is elongate, pointed, with the sheaths of the wings and 

 legs extending almost to the tip of the abdomen, and of a honey yellow 

 color." 



L. lyshnachice'lla (n. sp.) 



The larva is cylindrical and very small. It makes a very small 

 tentiform mine on the under side of the leaves of (Lyshnachia lanceolata) 

 the loosestrife. The imago is, no doubt, very small — probably not larger 

 than L. desmodiella, Clem., which is the smallest known species of this 

 genus ; but I have not succeeded in rearing it.

It is necessary to make some corrections of the specific description 

 of this species, as follows, viz.: The basal streak is sometimes confined 

 to the wing, and does not pass back out on to the tegular and thorax ; 

 neither are the face and under surface deep steel blue, as stated ; this 

 error must have been caused by some peculiar direction or character 

 of the light by which it was viewed ; they are rather of a shining me- 

 tallic white, and there is a saffron yellow spot on each side of each ab- 

 dominal segment ; the legs are of the same metallic hue with the ab- 

 domen, but the tarsi are annulate with black ; the anterior tibia? are 

 fuscous on their anterior surfaces, and the posterior are saffron yellow. 



I have bred the species mentioned loc. cit. as mining leaves of Helian- 

 thus gigayitea since the former note was written, and find it to be this 

 species, as I supposed. It is very different from the species described 

 post as L. helianthivorella, especially as to the character of the mine. 



L. helianthivorella (n. sp.) 



I do not deem it necessary to give a full description of this species, 

 but will simply point out the particulars in which it differs from 

 L. anWrosiceella (sup.) : First — the mine of ambrosiceella is very small,
