spines on segments 2-4 anteriorly directed, those on segments 6-8 

 posteriorly directed ; segment 2 with 8 simple spines in a transverse 

 row across middle of segment, the row being divided in two by a 

 median space ; anterior to the outermost spine on either end of the row 

 are 2 hairs ; segments 3 and 4 with 8 simple spines in transverse row, 

 situated somewhat before the posterior margin, each row also being 

 separated into two by a median space ; segment 6 with a band across 

 the anterior margin that is composed of comblike groups, each with 

 yj spines, the band divided by a median space; segment 7 with 12 

 spines in transverse row at anterior margin, the row being interrupted 

 by a median space ; spines truncate, simple, or with from 2-6 teeth 

 at apex; also with 8-12 combs (2-6 spines each) lateral to the row of 

 spines ; segment 8 with 22 simple or bifid spines in transverse row 

 along anterior margin, the row divided in two by a median space ; with 

 truncate combs (2-6 spines each) that are either simple or bifid lateral 

 to the row of spines and intermixed with it. Ventral surface of ab- 

 dominal segments : No granulosity ; all spines are anteriorly directed ; 

 segment 5 with 4 simple spines in transverse row three- fourths the 

 distance from anterior margin, the row being divided by a median 

 space ; segments 6 and 7 with similar rows of simple spines, but with 

 the two spines on either side of midline more separated than on seg- 

 ment 5, the distance between them being approximately equal to that 

 of the median space. Terminal spines absent. 



Respiratory apparatus (pi. 38, fig. 315) of each side arising a little 

 behind the anterior margin of thorax; composed of a dorsal element 

 and lateroventral element, both appearing hornlike; dorsal element 

 very broad, compressed dorsoventrally, and black along the distal 

 three-fourths of its length ; pseudoarticulations simple on lateroventral 

 element, those on dorsal element appearing to radiate from the midline 

 toward the lateral and anterior margins; both elements with micro- 

 scopic spicules. Length of dorsal element, 0.9 mm. ; length of ventral 

 element, 1.5 mm.; width of dorsal element, 0.2 mm. 



Cocoon (pi. 39, fig. 355) : Length of base, 2.9 mm.; maximum 

 length, 3.6 mm.; maximum width, 1.4 mm.; maximum height, 1.6 

 mm. Cocoon slipper-shaped, parchmentlike texture, threads not visi- 

 ble ; rim of anterior aperture somewhat thickened ; no festoons or 

 prolongations. Cocoon covers abdomen and half of thorax, attached 

 along 0.5 of its base. 



Larva. — None available.
