Hub. Karwar, N. Canara, 8. India. 



Three bred specimens known ; two in the Britisli Museum, f'/jir 17. viii. '97 ; 

 the third, somewhat crippled, in the Trinji' Museum. 



Easily recognised liy tlie pattern of the forewing. 



Mimas tiliae (p. 304). 



The larva of ^f. tiliae chi-istophi, of which Messrs. Staudinger and Bang- 

 Haas have sent us a specimen, agrees witli that of .lA tiliai' filini'. 



Sphinx ocellata (p- 317). 



On p. :i2'i we have referred to three hybrids as ^[fcmide.i" with c? -antennae. 

 Prof. Standfnss informs us in lift, that the two specimens populi x ocellata 

 bred by him are not females. We have now re-e.Kamined onr two individnals 

 in question, and find that we have been taken in by the thin antennae and the 

 contracted abdomen. The two specimens prove ou dissection to have a male 

 sexual armature, and to possess eight external abdominal segments like normal 

 SS. There is, therefore, nothing remarkable in the antennae as stated, except 

 that they are too thin for (JcJ, a sign of the weakening influence of hybridisation. 

 We add that the S populi x ocellata has the s])ikes of the jienis-sheath nearly 

 as lieavy as the S populi. 



Amorpha populi populi (p. 333).

Phyllosphingia dissimilis (p. 338). 



We have now 'Z jmpae and 1 larva, bimglit from Messrs. Staudinger and Bang- 

 Haas. 



Tiie jiupa is very close to that of Cressonia juc/laiulis. Black-brown, very 

 rough, (ipai|ne. Head: two tubercles between bases of antennae ; frons produced 

 into three prominences, each sinuate at tip, one mesial and the others near eyes. 

 Tongne much shorter than foreleg. Anterior femur not visible. Grannies of 

 antenna pointed. Mesonotnm and liase of forewing witli a few tubendes. Abdomen 

 flattened beneath, especially tlu^ last segments, irregularly grooved, minutely and 

 densely grannlose ; npperside with sharply pointed grannies, which are densest 

 on the pro.ximal segments ; segments 4, 5 and with a subapical belt of pointed 

 tubercles, these tubercles vestigial or small on underside. The belt reminds 

 one of that of Perge.m elpenor (etc.), but has quite a different position. Trace 

 of horn distinct. Pointed lateral granules of eighth segment directed forward, 

 ('remaster flattened, truncate, broad, the angles produced laterad each into a tooth. 



Larva grannlose, the granules dispersed ; lateral granules denser and higher 

 than the dorsal ones and each with a red wing round its base. Seven oblique 

 side-stripes of enlarged granules, the stripes extending over two segments and
