882, second paragraph. Dr. Fitch observed this caterpillar attacking plums, as long 

 ago as 1870, as appears from the following passages found among his notes : — 



"June 5, 1870. Noticed a young Smith's Orleans plum, now grown to over a half 

 inch in length, having a conical hole eaten in its side, passing deep in, through the 

 centre. First thought this the work of some bird ; but looking further saw the next 

 plum below eaten through and through till it was now nearly all consumed and this 

 worm with its head sunk into the hollow remaining part of the plum, and its body 

 clinging to the upper end of the fruit stem. Put the worm into a tumbler with a 

 young wild plum and leaves. 



"June 6, 1870, it has eaten a hole deep iu the side of the plum on which it stands 

 with its head sunk down into this hole, and has discharged a profusion of soft wet 

 feces of a dull pale yellow color, some adhering to the side of the plum, but most of 

 them fallen down to the bottom of the tumbler. 



"June 10, it has now eaten out all the inside of the plum, making a hollow cavity in 

 it, consuming about a third of the plum and has fastened itself to the paper covering 

 the tumbler— fixing its hind end to the paper, and with several silk threads forming a 

 loop to hold the fore part of its body up in contact with the paper— these threads com- 

 mencing separately and spread apart at their ends, and drawn together and sunk into 

 the suture between the thorax and abdomen. It has thus taken on its pupa form, held 

 against the paper with its back downwards." 

 I add his descriptions of the early stages :— 



" iarea 0.55 long, 0.20 thick, regular oval or a little more narrowed at hind end, 

 bluntly rounded at each end, sutures very distinct, marked by transverse constrictions, 

 except the two last, which are less plain. Twelve segments, the anterior ones, after the 

 head, shortest, and slightly increasing in length backward. No projecting processes. 

 Surface closely bearded with short hairs. Color bright apple green. A faint pale green- 

 ish-yellow dorsal line, bordered each side by a faint green stripe— this yellow line ending 

 on the fourth segment from the tip, and these last segments have a deeper green dorsal 

 stripe faintly bordered each side with pale greenish yellow. The back occupied on 

 each side by oblique faint stripes of green and greenish yellow, alternating; the yellow 

 stripes beginning a little back of each breathing pore, and embracing the pore, and 

 passing diagonally forward and upward across the two segments next forward of the 

 pore, to the green dorsal stripes bordering the dorsal line. Breathing pores very small, 

 glossy, nankin yellow dots. Lower part of each side green, with a slender, pale yellow 

 stripe. Underside and legs dull whitish. 



" Pxipa 0.35 long, and about 0.20 wide and 0.20 high, oval, broadest beyond the mid- 

 dle, the anterior third of its length slightly narrower than it is farther back; anterior 

 end bluntly rounded ; hind end gradually tapered to a bluntly rounded tip. Abdominal 

 segments distinctly marked by impressed transverse sutures. Head separated from the 

 body by a similar transverse suture, its anterior side rounded, the line bounding it 

 forming about a third part of a circle. Color dull yellowish brown, mottled with black, 

 the whole surface bearded profusely with gray hairs, except on the flattened un- 

 derside. The spiracles forming a row of white dots along each side ; and in the suture 

 at base of head, near its outer end on each side is a short streak resembling white 

 pruinous matter. 



"July 1st found it hatched aThecla butterfly, lying dead on bottom of tumbler." His 

 description of the same enables me to determine it to be Thecla liparops. 

 907, line 35, /or continues, read continue. 

 960, line 29, /or Astralagus, read Astragalus. 



962, line lC-13 from bottom. As stated above in these additions, Sepp asserts 

 that the caterpillar of "Thecla" ingae, and of Nymphidium caricae, the latter one 

 of the Lemoniinae, are likewise attended by ants, and presumably for the same cause 

 as the larvae of Lycaenldi. 



Last line. See preceding note.
