64 SUBANTARCTIC ISLANDS OP NEW ZEALAND. [Entomology. 



Cacoecia syntona. (p. 73.) 



I ' Two specimens of this interesting insect were bred from larvae, inadvertently 

 taken by Mr. J. S. Tennant amongst botanical specimens of Pleurophyllum speciosum 

 at Port Ross on the 28th November, 1907. The pupa was noted on the 10th January, 

 and the moth emerged on the 14th February, 1908. In this instance a valuable 

 entomological discovery was made at the sacrifice of a few specimens of a well-known 

 plant. (Plate II, fig. 8.) 



Heterocrossa gonosemana. (p. 74.) 



Tliis pretty species occurred amongst Aspidium vestitum in forest at Carnley 

 Harbour, Norman's Inlet, and on Enderby Island. It was very sluggish, and was 

 principally taken by beating the fronds of the fern into an umbrella. Most of 

 the specimens taken were considerably darker than the usual New Zealand form. 

 (Plate II, fig. 17.) 



Proterodestna byrsopola. (p. 74.) 



This insect is extremely sluggish, and the female must be almost, if not entirely, 

 incapable of flight. Fifteen specimens were taken, resting on the under-surfaces of 

 dead rata logs in the forest at Carnley Harbour ; the species was also observed at 

 Norman's Inlet. (Plate II — fig. 18, male ; fig. 19, female.) 



Plutella maculipennis ( crucif erarum) . 



One specimen of this common garden-pest occurred on Enderby Island, and 

 was evidently a relic of the Enderby Settlement. 



DiPTERA. 



Zaluscodes aucklandicus. (p. 130.) 



This remarkable species was common in damp places in forest, Carnley Harbour. 

 It runs rapidly over the ground, like a small harvestman spider. An extremely 

 fragile insect. The colour is white when alive. (Plate IV, fig. 1.) 



Simulium vexans. (p. 124.) 



This sandfly was very abundant near the beach and round the streams near 

 Carnley Harbour. Its bites were persistent and painful. 



Calliphora quadrimaculata. (p. 125.) 



This common New Zealand blowfly was a fearful pest in the camp, especially 

 during fairly calm mild weather. 



Polytocus spinicosta. (pp. 127 and 145.) 



Four males and five females of this very large and conspicuous fly were found 

 resting under dead rata logs in the forest at Carnley Harbour. No specimens were 

 observed on the wing, and all those found were very sluggish, and never attempted 

 to use their wings for flight. (Plate IV — fig. 2, male ; fig. 3, female.)
