This species also differs from A. violaceus, described by
Bolivar (' Jornal Sciencias Math. Physicas e Na~uraes,' Lisbon,
set. ii. tome i. 1589, p. 156), in the absence o[ black spots fromthe body and in its pale golden-green coloration. Its smallersize, the absence of the median black stripe on the pronotum,
and the absenco of black spots from the posterior femora
separate it from A. grammlcus (ibid. p. 157).

Tn~ species described at this time are all from New Zealandand belong to the Eriopterine genus Molophilus. This groupof flies is one of the largest and most involved in the

to whom my sincere thanks are extended for kind co-operation in making known the New Zealand crane-fly fauna.
The collections made by M. Andrg Tonnoir are especiallyrich in small and obscure species. The types of M. Tonnoir's
novelties have been returned to ]tim and will be depositedin the collections of the Cawthron I n s t i t u t e and Canterbury

Tillyard interpretation. From these figures it will be seenthat the costal, subeostal, and radial fields are the same in
the two systems. The vein called the anterior braneh of
Cubitus (CUl) in the Comstoek-Needham system becomes

the posterior tn',~neh of media (M4) following the T i l h a r d
modification. The basal deflection of Cu 1 of Comstock andNcedham becomes the m - c u cross-vein. According to
Tillyard, only a single branch of Cu (C~q) reaches themargin of the wing in the Tipulidw, the posterior branch(Cu~, fig. 2) being semi-atrophied and lying close behindthe main branch of Cu, in many eases, however, extending
to beyond the m-cu cross-vein. This latter vein has beeneonsidered as being the degenerate first Anal vein by Cmnstock and later students, but the writer now feels convincedof the eorreetness of the Tillyard interpretation of thisregion of the wing.
