than half as long as in Eriphia concolorella. I place it somewhat doubt- 

 fully in Elachista, because of the neuration, which approaches that of 

 Laverna. The submedian of the primaries is not furcate at the base ; the 

 cell is narrow and acuminate, with three subcostal branches to the 

 margin from near the end of the cell, besides the apical branch, which is 

 furcate before the apex, with one of its branches to each margin ; the 

 median is also three-branched, the last from the end of the cell almost 

 confluent with the furcate apical branch of the subcostal. 



In the secondaries the cell is rather wide, unclosed ; the subcostal is 

 distinct and furcate, with a branch to each margin ; the median is three- 

 branched (or two-branched, with an independent discal branch arising at 

 the median and indistinctly continued through the cell, which is 

 unclosed). 



Dark bronzy brown ; unicolorous. Al. ex. a little less than a third of 

 an inch. Not so slender an insect as Eriphia concolorella.

White ; a few ochreous yellow scales scattered over the primaries, 

 especially towards the apex. Al. ex. scarcely ^ inch. Season, May, 

 July, August and September.

young of polyxenus. 

 Dear Sir, — 



■j 



During the past summer [ have bred the young Polyxenus from the 

 egg. The eggs were found under the bark of dead pines, and were in 

 masses of about thirty, I should judge ; intermixed with them were 

 numerous hairs from the posterior part of the body of the adult. The 

 eggs are translucent white, sometime before the young appear turning 

 somewhat opaque ; in shape oval, long diameter barely one-hundredth of 

 an inch. 



Length of the young ten hours from the egg, seven two-hundredths of 

 an inch. The young differ in no marked manner from the adult, except 

 in the smaller number of segments, which are four, and in having only 

 three pairs of legs, attached to the three anterior segments. The fourth 

 segment is small and has the two tufts of silvery hair so characteristic of 

 the adult. Henry L. Moody, Maiden, Mass.
