no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 163 



Suranal plate regularly triangular, the surface rather rough, the edges with minute conical 

 tubercles and two small ones, one on each side of the middle of the upper surface. Anal legs 

 large, triangular, and with scattered stiff setce arising from the surface. Skin smooth, with 

 scattered short microscopic stiff setas. Pale yellow (in formalin), with broad irregular dark 

 rich steel-blue bands, one on the two liinder thoracic segments, two on each abdominal one, 

 the two bands becoming confluent on the tergum. Prothoracic segment and tenth abdominal, 

 including the suranal plate and anal legs, steel-blue, thoracic and abdominal legs steel-blue. 



Young larva, when 24 mm. in length (third stage?). 



It is almost exactly in shape and style of coloration as described under the last stage, but 

 the tubercles are a little larger in proportion to the body than in the final stage. 



In this stage the conical square-tipped tubercles on the main tubercles look like the stumps 

 of setae; they are either broken off or are not developed. It is a singular case of the total 

 reduction of the setag, showing that the genus Heniocha is a widely divergent member of the 

 Saturniinae. 



Young larva in a succeeding stage, length 28 mm. ; the head is considerably larger than in 

 the previous stage, otherwise the caterpillar does not differ from that of the preceding stage. 



This must be a very conspicuous larva. It is either probably poisonous or bad tasting, 

 its bright conspicuous colors being warning hues. 



It can not be a Ceratocampid, since there are six tubercles on the eighth abdominal seg- 

 ment, the two tergal ones being widely separate on both the eighth and ninth segments. This 

 feature would indicate that from its larval characters Heniocha belongs with the Saturniinae.
