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

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

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

 form it is unlike the elongate D. flammea Hinds, from New 

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

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