singular (fig. 19), and resemble those of some Coleoplera more than 

 those of an} r other Lepidoptera; the articulations are almost 

 obliterated; the outer lobe is reduced almost to a rudiment; the term- 

 inal joint of the inner lobe is enlarged, almost globular; only two of its 

 terminal processes are present, and it is densely clothed with long 

 hairs (compare fig. 19 with figs. 20-28). The maxillae separate it 

 from all other Lepidoptera, while the labrum separates it from all of 

 these above discussed, and seems to unite it with Bedellia, Antis- 

 pila, Aspidisca and Ncpticula. 



Bedellia (fig. 68, labrum of larva) is placed by Mr. Stainton in 

 Elachistadai. The larval labrum is not distinctty trilobed, but the 

 notch is widened into a distinct space, which gives the appearance of 

 trilobation. It has ten spines on its upper surface (as in Lithocol- 

 letis, etc.), but has ten others around its anterior margin. 



Neplicula (figs. 69 and 71) has the notch still more widened, and 

 the trilobation distinct; the teeth are indistinct; I detect no spines, 

 except the ten spines or teeth around the margin. On the whole, in spite 

 of differences, it seems to be about equally related to Bedellia and 

 Tischeria (it is proper to say, however, that iniV. pteliceella the labrum 

 (fig. 72) differs from that of all of the other Nepticula larvae that I 

 have examined. Mr. Stainton places Nepticula and Trifurcula 

 (which I have included in Nepticula) in his family Nepticuladw. The 

 maxillae do not differ in any important respect from those figured at 

 figs. 20-26. The larval labrum, while appearing to be between that 

 of Bedellia and Tischeria, as above stated, seems to be about equally 

 related to that of Antispila (figs. 70 and 73), or Aspidisca (fig. 74), in 

 which, although the notch is present, the tendency to trilobation is 

 also distinct; the number of the spines, which are obsolete, varies from 

 four in Aspidisca (fig. 74), and in N . pteliozella (fig. 72), to eight in 

 Antispila cornifoiliella (fig. 70), or only two in A. ampelopsiella (fig. 

 73). Antispila has floated around among the Tineina as if playing 

 " puss wants a corner." It found a corner for a time among 

 Elachistadai, from which Mr. Stainton removes it, and places it in 

 Glypipterygidce. Aspidisca must go with it, and both seem to me to 

 be related by the larval trophi to Nepticula and to Bedellia, and, so 

 far as the labrum is concerned, to Tischeria, which, however, is sepa- 

 rated widely enough from them by the maxillae. I have not seen the larva 

 of Elachista. Indeed, the larva of only one of our American species is 

 known at all, and that I think only to Dr. Clemens. But the imago 

 grades through some of our genera of small moths (Elachista
