270 THE entomologist's record. 



hairs, the larva of Tinolius, the latter, however, is a semi- 

 looper and therefore not nearly related to it." (The italics are 

 mine.) One would suppose not much nearer than Pieris bras- 

 siccE is to Eitbolia ccrvinata, though the young larvae of both 

 these have their hairs tipped with moisture. One is, indeed, 

 astonished that so accomplished a systematist as Mr. Butler, 

 should found such startling conclusions on mere superficial 

 resemblances of full-grown larvae, whilst his careful examina- 

 tion of the neuration in Acronycta and certain other genera, 

 instead of confirming his conclusions, clearly shows them to 

 be untenable. He finds a uniform type of neuration in 

 Acronycta, and some little differences, little, but of importance, 

 for the neuration differs only in small particulars, amongst a 

 large number of more or less allied families, between Acronycta 

 and each of the several groups amongst which he proposes to 

 distribute them. 



To return to our Vim in in larvae. As I have stated under 

 each species, the larvae, when newly hatched are pale, but in 

 a short time, often only a few minutes, become black, the 

 tubercles being set so closely together as to show nothing but 

 the black tubercles, and it is necessary they should grow a 

 little before their real features can be fully, or at least at all 

 easily seen. It results that the figures are drawn at different 

 ages of the several larvae and at different degrees of enlarge- 

 ment. Throughout the whole genus, the nth segment is pale 

 (and "weak") and in Viuiinia 3. 4, 6. 7, 10 and 13 are also 

 pale, the other segments being darker. There is a tendency 

 in all of them to develop a white ring round each tubercle, 

 most marked on the pale segments, and in the Plate is best 

 seen in fig. 4, nicnyantJiidis, and 7, rum ids. In nienyantJiidis, 

 this proceeds to the fullest development, giving to the pale seg- 

 ments a porcelain-like density and solidity, the pale portions 

 of the other species always having a somewhat delicate trans- 

 parent character. The echinate character of the anterior 

 trapezoidal tubercles, each hair starting from a pyramidal base 

 and the whole tubercle forming a slight dorsal boss, is not 

 brought out in any of the figures, it is just hinted at in fig. 2, 

 anriconia. This character is most marked in ritviicis and 

 venosa, least so in menyanthidis. 



It remains the case, however, that, notwithstanding the 

 great peculiarities which distinguish these young larvae from 

 all others, the five species present only slight characters, chiefly 

 in the development and intensity of the pale rings round the
