PANACEA. 303 



sparsely with minute glassy tubercles ; basal half of labruni 

 longitudinally striate. Body dull except for the enamel-like 

 surface of the ocellus. Horn of medium length, slightly 

 down- curved, somewhat flattened laterally, thick at base and 

 tapering evenly to a sharp point ; covered sparsely with minute 

 tubercles. 



Coloration. — Head pale olive-green with subcutaneous 

 dusky dots ; false clypeus edged narrowly Avith white, labrum 

 glassy- white, the basal half suffused with pale fuscous ; ligula 

 reddish-brown ; basal segment of antenna greenish, other 

 segments reddish -brown ; mandible pale rusty with tip broadly 

 reddish- brown. Body rich olive-green, segments 2 to 4 and 

 the dorsum of the remaining segments up to 12 suffused with 

 pale brown ; 13 and 14. yellowish-brown ; a narrow brown 

 dorsal stripe on 3 and 4, continuing as a series of brown spots 

 near the front margins of 5 to 11 ; a narrow dark brown 

 dorso-lateral stripe on 2 to 4 ; a broad, pale, yellowish- brown 

 spiracular stripe from the front margin of 2 to the spiracle 

 of 5, which it surrounds, and continuing as a waved stripe on 

 7 to 10 ; a large ocellus behind the front margin of 5, centre 

 round and black, bordered behind and below broadly with 

 dark brown and then narrowly with pale brown ; the area 

 between the ocelli spotted with white. Horn olive-green, 

 tip shortly yellow ; legs yellow, prolegs pale brown ; venter 

 olive -green, suffused with blackish on 2 to 4. Spiracles oval,

Pupa. — Slender in build ; tongue-sheath narrow and keeled 

 in front, widening basad, semicircular in lateral aspect ; 

 a large deep depression, invisible from above, between the 

 base of the sheath and the eye. Surface dull ; base and venter 

 of tongue -sheath deeply corrugate, rest of body covered 

 with low rounded ridges and tumidities ; the front bevels of 

 segments 8, 9 and 10 transversely ridged with narrow parallel 

 lines. Spiracle of 2 a narrow slit, with a raised oval lobe 

 projecting from the front margin of 3 just touching it ; other 

 spiracles broadly oval, the central slit with narrow, raised 

 edges lying in an oval depression. Cremaster an equilateral 

 triangle with the apex broadly rounded- truncate, the sides, 

 seen from the dorsal aspect, in the same line as the sides of 

 segment 14, so that it appears to be a continuation of that 

 segment ; the ventral surface deeply, longitudinally concave, 

 the concavity continuous with a round axial depression in the 

 hind end of 14 ; four pairs of strong, chitinized, bifid shafts, 

 each arm ending in a hook, one shaft subdorsal at apex of 

 cremaster, one lateral and one dorso-lateral farther for- 

 wards, and one subdorsal farther forward still, the apical 

 pair the stoutest and branched well above base, the other
