M‘Lacutan.—On New Zealand Neuroptera. xev 
Very closely allied to T. zealandica, but considerably larger; on the 
abdomen the basal spot at the base of segment 1 is divided ; the superior 
appendages are much exserted, scarcely one half shorter than the inferior, 
subtriangular, the lower edge concave, hence the tips are much eurved down- 
ward (the black tubercle is present as in 7. zealandica). There are four 
cellules between the quadrilateral and the nodus in all the wings, and the 
pterostigma is larger and surmounts fully two cellules ; fifteen postcubital 
nervules in the anterior wings. 
Notwithstanding the great similarity I must, for the present, consider this 
insect specifically distinct from 7, zealandica. Only one male has been 
examined, and that rather immature, the red markings on the head and thorax 
not being fully developed and more or less yellowish, and the pterostigma 
dusky yellow. 
PLANIPENNIA. 
Sialidee. 
Genus CHAULIOoDEs, Latreille. 
18. Chauliodes dumis Walker.

This insect varies much in size. Of five individuals in my collection the 
smallest (male) has an expanse of wings of only 25”, the largest (female) 
expands to 417. The structure of the antenne is the same in both sexes. 
Myrmeleontide. 
Genus Мүвмегкох, Linné, Hagen. 
19. Myrmeleon acutus, Walker.

. Appears to be the sole representative in New Zealand of this extensive 
family. The hind wings of the male possess a “ pelote" or knob at the 
extreme base of the inner margin, as in many other species. 
Osmylidee. 
Genus SrENosMYLUS, M“Lachlan. 
The New Zealand species might be transferred to a new genus on account 
of the subfaleate wings and excised apical margin; but the Australian 
S. pallidus is in some respects intermediate between them and the typical 
species ; hence their retention in this pum will answer every purpose, at any 
rate for the present.
