a ARCTIAD^. 



appears to be alwaj-s free at the base, this being* rarely the case in 

 the Arctids ; this occurs in various parts of the Noctuidce^ such as 

 Stilbia in the Caradrinince, Rhanidopliora ., and Eligma in the 

 NoctuincE ; several genera in the Tarache group, all the genera of 

 Sarrothripince, several of the allies of Acontia (these last two having 

 also the Arctid character of a bar-shaped retinaculum), and many 

 genera in the Hypenince. 



The nearest allies of the Arctiadce among the Noctaidoi seem to 

 be the Sarrothripince and Acontiance, the former being collaterals of 

 the LithosiancB, the latter of the Arctiance. 



Larvae with all the prologs present ; the tubercles normal, con- 

 verted into large warts beaiing many hairs and forming a cocoon 

 of silk interwoven with hair. 



In the abnormal Tyria jacobwce the warts have only one hair, 

 except V which has two hairs and vii with four, this reduction of 

 the hair being correlated with its warning coloration.
