from above ; palpi extremely short ; the antennae compressed, 

 the joints imbricated ; shoulders square, in aline with the costal 

 margin of primaries : primaries trigonate, produced at apex, 

 outer margin slightlj concave ; secondaries subtrigonate, the 

 costal margin straight, abdominal margin slightly concave, 

 anal angle produced, outer margin convex ; legs clothed with 

 long hair to the end of the tarsi. Type H. insignis, 



47. Hypsomadius insignis^ n. sp. 



Wings above shining silver-grey, crossed by two lines, the 

 inner one of primaries and the outer one of secondaries irre- 

 gularly dentate-sinuate, these and the inner one of secondaries 

 testaceous : primaries with the outer line oblique, running to 

 apex, dark red ; apical area above the line irrorated with 

 black ; fringe dark red ; costal margin ochreous : secondaries 

 with the fringe testaceous : body grey, prothorax white, sides 

 of abdomen and anus rosy ; head orange, with four lateral 

 patches of crimson scales ; legs below whitish ; femora whitish 

 above ; tibiae yellow, with a black central spot above, rose-

Saturniidae. 

 48. Caligula japionica, Moore. 



The pupa of this species, but not the imago, has been de- 

 scribed by Mr. Moore. It is nearly allied to C. simla, but may 

 at once be distinguished by the inner transverse stripe on both 

 wings, which in the primaries is nearly straight (slightly 

 concave), instead of 3-shaped, and in the secondaries angu- 

 larly sigmoidal, instead of being regularly convex with an 

 abrupt angle near the abdominal margin. Expanse, (J 5 inches 

 2 lines, ? 5 inches 1-5 lines.
