280 EKNEST WARREN. 



and projects further back over the anus, the tubercles are 

 smaller, and the little marginal tubercles are fewer and not 

 regularly arranged as in maia. In the present offspring the 

 area was not normal in shape, and perhaps on the whole in 

 general outline it Avas intermediate between that of maia 

 and menippe. The condition of the tubercles and hairs, 

 however, was in no way intermediate ; it was rather peculiar, 

 but obviously it was a modification of the menippe type and 

 had no connection with the maia arrangement. 



The fact that the arrangement of the tubercles and hairs in 

 no way resembled that in maia renders it extremely probable 

 that the more or less intermediate shape of the area was a 

 quite accidental occurrence, due to the slight deformity of the 

 posterior portion of the body. 



(5) The lateral raised area at the sides of the last false foot 

 in the present offspring was like that of menippe and not 

 like that of maia in general outline and arrangement of hairs, 

 but it was rather small. On the right side of the body, as 

 already remarked, the area was yellowish except along its 

 margin which was dark brown. 



(6) In maia the head is relatively narrower than in 

 menippe. In the present offspring the head resembled that 

 of menippe. 



(7) In maia the mean lengths of first, second, and third 

 joints of the true Avalking legs are in the proportions of 

 100 : 84 : 48, in menippe 100 : 94 : 70; in the present offspring 

 the proportions did not differ appreciably from those of 

 menippe; they were 100 : 105 : 74, thus they showed no hint 

 of a shortened terminal joint, which is characteristic of maia. 



(8) In maia the terminal claws of the thoracic legs are 

 brighter in colour and considerably larger than in menippe, 

 while in the present offspring they did not differ in the least 

 from those in menippe. 



(9) In all other characters that were observed no differences 

 could be detected between the present offspring and the young 

 larvae of menippe. 



On the whole it may be said that no influence of the male
