Median Veins (M1–4.—The secondary median fork (mf') is basad to the secondary radial fork (rf') in incongruella, lucilia, caustica, barbarica, rosicoma, and zonodoxa; in calliarcha mf', is distad to rf', and in all the other forms the position of these forks is about equal. The relative position of the forks seems to be of little importance, as, if insisted on, it would divide such closely related forms as lucilia and calliarcha. There is no trace of the fourth median vein in any of the species. First Cubital Vein (Cu1).—In doroxena Cu1 is more remote from M3 than in any other species: it may be noted that doroxena is the broadest-winged form. There is no cross-vein between Cu1a and M3 in any of the species. Fig. 11.—Hindwing of Micropardalis doroxena (Meyr.). (For lettering see fig. 1.) Fig. 12.—Hindwing of Sabatinca demissa Philp. (For lettering see fig. 1.) Second Cubital (Cu2), and Anal Veins (1A, 2A and 3A).—Cu2 is captured by 1A for about half its length, at which point it bends downwards and joins 2A, Cu2 continuing alone as a very weak vein. This condition occurs in all the species except rosicoma and zonodoxa, in which forms the anal are very weak and 1A does not leave Cu2 to connect with 2A. In conclusion, I have pleasure in expressing my gratitude to Mr. G. V. Hudson, F.E.S., F.N.Z.Inst., and Mr. Charles E. Clarke, F.E.S., for specimens of some of the more rare forms of the genus, without the opportunity of examining which my paper must have lacked completeness. Mr. Clarke kindly supplied me with several specimens of rosicoma, and also with a pair of his lucilia, a form which I think must be regarded as the most primitive in the genus. To Mr. Hudson's generosity I am indebted for an example of zonodoxa, the gift being all the more appreciated as the specimen was one of the only two examples of this form in New Zealand collections. To Dr. Tillyard, Chief of the Biological Department of the Cawthron Institute, I am under a deep obligation for much valuable advice. To all these gentlemen I desire to express my best thanks.
