450 MESSES. MELTILL AND STA.NDEN ON [June 18, 



This species does not seem very near, save superficially, to any 

 variety of the protean D. lymneiformis Kiener, e. g. patula and 

 fragilis Eeeve, with which we have carefully compared it. In 

 form it is unlike the elongate D. fiammea Hiuds, from New^ 

 Ireland, though to some extent the disposition of the markings is 

 identical. D. delicata Eve. is likewise more elongate.
