but rather large oval swelling, the vestige of a tubercle, which bears five to six setae. Further 

 down at the base of the first pair of legs is a low broad chestnut-colored tubercle, not so high 

 as broad, and bearing six setoe. 



On the second and third thoracic and all the abdominal segments are eight rows of long 

 stout very sharp smooth spines, curved backward, those of the two dorsal rows a little longer 

 than those of the supraspiracular rows. The dorsal thoracic and median spine of 8th abdominal 

 segment a little longer and larger than the other abdominal ones. Each spine bears five or six 

 long pale setas, radiating from the main stem. All of the spines are of the same pale chestnut 

 or deep reddish yellow hue, tipped with dark. The dorso-median spine on the eighth abdominal 

 segment is twice as thick as the others and deeply forked to a quarter of the length, and there seems 

 to be faint indications of a median impressed line, as if the fusion of the two spines had occurred 

 late in larval life. 



The. spines of the lowest series near the base of the legs are stout, but shorter and black. 

 On the ninth abdominal segment are six rows, the four dorsal ones large, nearly as long as 

 those of the eighth segment and curved backward. 



The suranal plate is large, round, smooth, but the surface is rugose and with scattered 

 small piliferous warts; the edge thicker, but not spiniferous. Anal legs large, thick, triangular. 



The body is black, the thoracic and abdominal legs black, except those of the anal pair 

 and the suranal plate, which are bright chestnut red. 



Like the larva of Urota, the upper surface of the second and third thoracic segments are 

 showily and brightly ornamented with a transverse row on the front and hind edge of each segment 

 of white rosettelike flattened soft warts, which are round where not crowded; but when crowded 

 tending to become polygonal and to bear in the center a papilla, or sometimes there are two 

 excentric ones; the lines formed by these warts are more or less wavy. The spiracles are 

 encircled by them, being sometimes two or three deep. On the dorsal side of the segments 

 they tend to be arranged in the foim of a W. 



This larva, which is very well preserved, was kindly loaned me by the American Museum 

 of Natural History, through Mr. W. Beutenmuller. It is No. 335, and is from the collection 

 presented by Mr. William Schaus. It was received by him from Sierra Leone. 



In general appearance it resembles the larva of Bunaea caffraria, but more especially 



Acanthocampa belina.

Imago. — One <S , one $ . A very much smaller species than M. heriUa, the $ differing 

 from the $ of that large species in the outer edge being more oblique and entire, while the 

 bind wings are not ragged along the edge. Head and body reddish tawny. [The venation 

 also differs.] 



Fore wings long and narrow, costa slightly incurved on the basal two-thirds, beyond much 

 arched; apex broad and square, outer edge deeply excavated and the edge with the fringe is 

 very slightly uneven, almost scalloped; inner edge very long. No lines, discal spots, or other 

 distinctive markings. The wing is tawny dull ochreous or buff yellow, washed with pink and 

 reddish, and dusted with reddish-brown scales; costa spotted with brown, as is the outer edge 

 and fringe, also the inner edge; as signs of a discal spot. 



Hind wings clearer buff yellow, with violaceous and reddish short wrinkled lines at the inner 

 angle and along the inner edge, but no lines crossing the wing and no discal spots. Under side 

 of the fore wings paler, with a large distinct deep pink patch between the costal and inner 

 edges of the wing, and the brown costal spots are larger and more distinct than above. 



$ . Considerably larger than c? , fore wings with the apex rounded, not square, broader 

 than in the <S , but slightly falcate; buff yellow, costal and inner edge marked with short 

 transverse reddish-brown stripes ; outer edge entire and fringe concolorous with the rest of the 

 wing, but with a few pink red scales behind the apex and at the inner angle. A faint oblique
