elluvi, as these are figured in Ins. Brit., though the neuration is exactly that 

 of ocnerostoinella. I have not examined the neuration of the fore wings, 

 but the shape is very nearly that of sericiellum, loc. cit. The labial palpi 

 are those of Tinagvia sericiellum : and the maxillary palpi are about equal 

 to the first joint of the labial. 



The ornamentation is that of Tinagnia, and of the other genera above 

 named as well. There are the usual two silvery white dorsal spots, one 

 near the base, the other at the anal angle ; the latter is not a triangle, as it 

 is described in gracilis, or if it is triangular, the apex is very obtuse ; it 

 points a little obliquely backwards ; the other lies parallel to it, pointing 

 also a little backwards, is of the same length but narrower, and reaches 

 the fold. Hind wings pale fuscous ; ciliae grayish fuscous. Otherwise 

 the entire insect is of a rich brown, but glittering so with metallic reflec- 

 tions that it is difticult to get a good view of its true color. These 

 reflections from the wings, thorax and abdomen are brassy, or rather 

 bronze ; from the head, palpi and under surface of the abdomen, silvery 

 or like burnished steel ; the antennae are of the same color with the fore 

 wings, the legs are a little paler. Wing expanse, 2 ^ lines. 



Described from a single specimen taken April 24th, resting on the body 

 of an apple tree (on the edge of a forest, however,) near Covington, 

 Kentucky. I did not observe anything peculiar in its position in the 

 hasty glance which I gave it, and, indeed, was under the impression that 

 it was an early specimen of Aspidisca splendoriferella Cham. In Europe 

 species of Heliozella are said to appear flying in hot sunshine in May and 

 June. In ten years of dilligent observation, I have never met with a 

 mine resembling that made by H. rcsplendell/u;! (the only species of which 

 the larva is known), except in July and August, 1875, in the region of 

 Mammoth Cave. There a mine was not uncommon in Chestnut leaves. 

 It was a narrow line beginning always by the side of a lateral rib, running 

 thence towards but not to the edge of the leaf, then crossing over the 

 space to the next rib, and passing along beside it down to the midrib, 

 which it entered and burrowed along down it towards the stem, emerging 

 from the midrib through a little slit, looking like two minute half parted 

 lips. I never saw the larva, and saw no trace of its having left the mid- 

 rib, and cut out from the cuticle of the leaf an oval case in which it 

 might descend to the ground and pass the pupa state like H.resplendell urn, 

 in Alnus leaves. 



I believe I have already somewhere alluded to the connection which
