of traces of maxillary palpi ; but I can only find with difficulty a slight 

 trace of the maxillary palpi. This would make it almost a true obtect 

 pupa, which is far removed from the Cossidse. 



The following descriptions contain some details not specially 

 mentioned in Miss Murtfeldt's article : 



Larva. — Head rounded, flattened, small, partly retracted ; clypeal 

 sutures depressed, upper segment of labium forming a ridge ; dark brown, 

 blackish on the narrow lateral angle; width, 1.3 mm. Body segments 

 distinct, creased several times in the incisures but not distinctly annulated, 

 joint 13 divided. Cervical shield large, bisected, inegularly marked in 

 black. Setae distinct, from rather large, flat dark tubercles; i. and ii. in 

 trapezoidal form, iii. lateral, iv. and v. from a single substigmatal tubercle, 

 vi. posteriorly, vii. above the base of the leg with three setse, viii. single ; 

 a small secondary tubercle with one little seta before the upper part of the 

 spiracle. On the thorax normal, the setpe of i. and ii. united in pairs, 

 iv. and v. united, vi. with one seta on joints 3 and 4. Thoracic feet well 

 developed, armed with setse and claw. Abdoaiinal feet distinct, rather 

 slender ; crotchets in a narrow ellipse, broken on the outer side, a single 

 row, but doubly clawed, a slight hook on the outside as well as the more 

 distinct one on the inside, both small. 



Pupa. — Smooth, obtected, thickest through the second abdominal 

 segment, slightly tapering each way, rounded, the head a little projecting. 

 Anal end rounded, cremaster without projection, but with four rather 

 long, stout, recurved hooks. Fifth and sixth abdominal segments move- 

 able. Cases reaching to the end of the fourth segment ; eye covered by 

 a single piece, separated below by the small, lanceolate labium ; maxillae 

 reaching about one-third the length of the cases, a small piece indistinctly 

 segmented off at the base next to the labium ; first leg reaching two-thirds 

 the length of the cases, enclosing a small elliptical piece of its basal part 

 next to the maxilla ; second leg reaching to the tip of the cases, apparently 

 touching the eye, but on careful focusing a small piece seems to be cut 

 off" at the base, which I take to represent the maxillary palpus ; antennae 

 not attaining the extremity of either the second legs or the wing cases ; 

 third legs concealed. The spiracle on the first segment is concealed by a 

 projection of the hind wing case which extends to segment 3. Light 

 yellowish-brown, all the sutures narrowly and distinctly marked in dark 

 brown. Smooth, shining, no distinct punctures or wrinkles of any kind. 

 Length, 6.5 mm.; width, 2.5 mm.
