spiracular line, the caudal margin scarcely elevated adjacent 

 to the conjunctiva; spiracle of the third abdominal segment 

 and sometimes of the second partially covered by the wings; 

 tip of abdomen usually slightly produced into a blunt tip ; the 

 scars of the anal prolegs seldom distinct on each side the anal 

 plate; cremaster absent. Length, abdomen retracted, 23-26

Samia gloveri Strecker. — Color variable, usually dark brown 

 to black with traces of yellowish brown; face parts, appendages 

 and exposed surface of thorax with fine, indeterminate trans- 

 verse striations, abdominal segments finely, deeply rugose, usu- 

 ally velvety in appearance; antennae of male with the stem of 

 the flagellum about one-fourth the total width of the antenna, 

 the stem of the flagellum projecting slightly beyond the pectina- 

 tions, and extending almost to the tips of the second pair of legs, 

 the length about two and three-quarters times the breadth; 

 antennae of female with the stem of the flagellum about one- 

 third the total width of the antenna, extending to the tips of the 

 first pair of legs, the length four times the width; clypeus not 

 prominently convex above the labrum ; labrum variable, seldom 

 concave at proximal end and, if concave, only slightly so, width 

 greater than length and broadly curved at distal end; maxillae, 

 measured on meson, between one-fourth and one-fifth the length 

 of wings, seldom smoother than the other appendages, the 

 median length and greatest width approximately equal; meso- 

 thoracic spiracles partially covered by antennae; mesothorax 

 with alar area polished; second pair of wings never visible 

 around entire dorsal margin of the first pair of wings, but con- 

 cealed by the first pair of wings between the first and third 

 abdominal spiracles; metathorax without prominent tuber- 

 cles, a prominent, usually reddish tubercle scar on each side the 

 meson, and a small tubercle near each lateral margin of the 

 metathorax; abdomen with three rows of tubercle scars, con- 

 spicuous and polished ; cephalic margins of abdominal segments 

 5-7 with indications of a fiange-like plate near the meson, the 

 edges of the segment adjoining the transverse conjunctiva 

 longitudinally ridged but scarcely elevated; first and second 

 abdominal spiracles partially concealed by the wings; abdom- 

 inal segments 8-10 with the caudal end produced into a narrow
