90 PROOEIS 8TATICES. 



are about 5 mm. long ; the skin now set with little 

 points, the back pale yellow with the tubercles on it 

 darker, the dorsal line faintly dusky, the side pale 

 brown with the large tubercles on it pink ; in fact by this 

 time they seem to have assumed much of the mature 

 dress. Now, at the age of three and a half months, 

 they are from 7 to 8 mm. long, very plump, slightly 

 fusiform in figure, the head very small and retractile ; 

 the places of the usual tubercular dots are occupied by 

 large tubercles set with short bristles, the trapezoidals 

 being united in a pair of transversely elongated 

 tubercles ; the skin round the tubercles is set all over 

 with tiny branched points. 



I have five examples before me showing three 

 varieties of colouring; one has the back dirty white 

 with the tubercles on it slightly brownish, a dull pink 

 dorsal line of varying width, the dorsal tubercles 

 bordered on the outside with a scalloped brown line, the 

 large upper row of lateral tubercles rose pink, and the 

 two lower rows of small ones more brownish pink ; 

 the second variety has the back yellow with slightly 

 brownish tubercles, the lateral tubercles pinkish, and 

 the lower ones brownish ; and the third has the back 

 pale yellowish, and the sides dusky, with very little 

 tinge of pink ; in all the head is shining blackish, the 

 short bristles are dirty whitish tipped with brown, the 

 little points on the skin are shining black, the spiracles 

 yellowish-brown, placed just beneath the large lateral 

 tubercles. So far I can well separate them from the 

 larvae of Geryon by their greater size, their very much 

 brighter colouring, and by the form of the dorsal line, 

 which is not so decidedly a double dark line with a 

 pale centre ; in structure there is no difference that I 

 am able to detect. The frass of statices is, as might 

 be expected from the food, watery, and when the larvae 

 are small it is excluded in a long thread-like form.
