 Denham Ba}% 20th August ; four specimens captured while hovering over 

 Solarium and Tongan bean on No. 3 Terrace, north coast, 24th August.

Syrphus viridiceps. 



Three males and one female. Captured hovering over Solatium, in 

 sunshine, on No. 3 Terrace, 16th September. A male and female taken 

 in coitu. 



This species is found both in Austra ia and New Zealand, and is 

 identical with Captain Hutton's S. obesus. 



Fam. Anthomyidae. 

 Ophyra nigra. 



Two males and four females. Common. Two specimens caught in 

 sunshine on ngaio-tree, Denham Bay, 20th August ; four from the carcase 

 of a goat, north coast, 9th November. 



Common about dead sheep in Western Australia, but not, so far, found 

 in New Zealand. 



Fam. Dexiidae. 

 Dexia rubricarinata. 



Five males and four females. Captured from the carcase of a goat, 

 north coast, 9th November. 



An extremely abundant and very troublesome fly. This species has 

 a wide distribution from China, through the East Indies, Australia, Tas- 

 mania, and the Kermadecs, to New Zealand. I procured a large number 

 at Astrolabe during the summer of 1911. 



Fam. Muscidae. 

 Calliphora laemica. 



Five males and six females. Abundant in sunny places all over the 

 island. The specimens were captured while flying in a warm cave, known 

 as the Oven Cave, on the shores of the Green Lake, in the crater, 30th 

 October. 



Common in Australia, Polynesia, and New Zealand. 



There are also a number of the Muscidae acalyptratae which I am unable 

 to identify at present. 



The Nemocera are represented by two species of Culicidae, a Tipulid, 

 and some species of the Mycetophilidae, all of which are so much damaged 

 that identification, beyond the families, is impossible.
