C. minutisimella. N. s/>. 



Vertex, palpi and abdomen silvery; face rather sordid white: antennae 

 dark griseous or fuscous, tipped with whitish ; anterior wings brown mixed 

 towards the base confusedly with silvery, with a distinct silvery spot on 

 the costal margin, two others on the dorsal margin, one of which is just 

 behind the middle and the other farther back: one at the apex and one 

 on the costal margin opposite the space between the two dorsal ones. 

 In some lights these spots are not distinct. Ciliae and hind wings dark 

 griseous. 



Alar ex. scarcely exceeding }i inch. It is therefore probably the 

 smallest Lepidopteron known. Mr. Stainton, Nat. Hist. Tin., v. i, says 

 that Nepticula microtheriella, measuring i^ lines in alar ex., was then the 

 smallest. It is a shaggy and rather " uncanny " looking little moth. The 

 larva is unknown. I have taken the imago abundantly in May and July 

 at the lamp. But I find that I have but a single specimen left, for, as it 

 is too small to pin successfully, I placed it in a tin " cell " on a microscope 

 slide, covered by thin glass, held down by a rubber band, into which crept 

 villainous little Atropes and ate all my little Cyllene save one. 



NEPTICULA. 



Nepticula miners of leaves of the Sycamore (Platanus oecidentalis.) 



Three species of Nepticula mine these leaves. Dr. Clemens describes 

 these mines fully ( Proc. Ent. Soc. Phila., March, 1862 ). One of the 

 mines is at first a slender track filled with frass. Afterwards the mine is 

 expanded into a round blotch, almost obliterating the previous linear 

 mine. This is the mine of 



N platan ella Clem., Proc. Ent. Soc. Phila, Jwiy, 1862. 



It may be distinguished from the two other species by having the 

 wings shining dark brown, with a silvery costal streak about the middle, and 

 an opposite spot of the same hue on the dorsal margin. For other particulars 

 see Clemens' description. Al. ex. yg inch. Kentucky. 



The mine described by Dr.Clemens as No. 2 is linear, slightly enlarged 

 towards its extremity, with the terminal portion enlarged into a small 

 blotch just before the larva leaves it. // has a central line of frass. Dr. 

 Clemens was not acquainted with the imago which I call 



N. Clemensella. N sf. 



Palpi and face stramineous, tinged with rufous between the antennas 

 and eyes ; eye-caps yellowish silvery. Antennae pale fuscous. Primaries
