Fig. 11. — Chionaspis unilateralism Newstead ; a, young adult female after maceration 

 in potash ; Z>, left marginal tubercles ; c, one of the tubercles enlarged showing 

 spinnerets, &c. ; d, pygidium ; e, rudimentary antenna. 



Though the puparium of the female is very strikingly like that of Chionaspis 

 nlongaia, Green,* the female of C. unilateralis is clearly distinct and easily 

 recognisable by the extraordinary asymetrical arrangement of the large squama- 

 bearing lobes on the abdominal segments.
