29 Transactions.— Zoology. 
A very common and generally distributed species; taken at Hamilton, 
Wellington, Nelson, Mount Hutt, Akaroa, Christchurch, and Dunedin ; 
probably universally common ; in December, January, February, and April. 
Doubleday’s description is very clear and unmistakeable. Zeller, not 
being aware of this description, later described a totally different species of 
the genus from Europe under the same name, which cannot stand. 
4. Cr. angustipennis, Z. 
(Chilo angustipennis, Z., Hor. Ross, 1877, 15, Pl. L, 3; Chilo leucanialis, Butl., Proc. 
Zool. Soc. Lond., 1877, 401.) 
Male, female.—29—44 mm. Head white, sides of erown pale brownish- 
ochreous. Maxillary palpi white, towards base light brownish-ochreous. 
Labial palpi very long, white, externally light brownish-ochreous. Antenne 
whitish-fuscous. Thorax pale brownish-ochreous, with a broad white central 
longitudinal stripe, and margins of shoulders very narrowly white. Abdomen 
and legs ochreous-whitish. Forewings elongate, narrow, in female very 
narrow, not dilated posteriorily, costa in male moderately, in female slightly 
arched, apex in male very strongly, in female moderately produced, acute, 
hindmargin sinuate, very oblique; very pale dull ochreous; all veins on 
upper half of wing broadly suffused with white, nearly confluent, so that 
the whole costal half appears whitish; a rather broad white streak along 
inner margin from base to anal angle, suffusedly margined above at base 
with dark fuscous, and bordered on inner marginal edge by a slender fus- 
cous streak from 3 to anal angle, strongest in middle : cilia white. Hind- 
wings white, sometimes slightly ochreous-tinged ; cilia white. 
Very distinct by its large size, narrow forewings, produced apex, and the 
white suffusion of the forewings leaving only a narrow longitudinal sub- 
median band of the ochreous ground-colour. Zeller is certainly wrong in 
referring this species to Chilo on superficial grounds, since in venation it 
is a true Crambus, and its peculiarities of appearance are only exaggerations 
of essentially similar points in C. ramosellus, which is its nearest ally. 
Not uncommon in the neighbourhood of Christchurch in December, 
January, and March, frequenting undoubtedly the toi-grass (Arundo con- 
spicua). 
Zeller's name has the priority, having been published 1st April, 1877, 
whilst Butler's does not appear to have been read until 1st May in the same 
year. : 
b. Cr. dicrenellus, n. sp. 
Male, female.—98-82 mm. Head white, sides of crown and anterior 
margin of eyes brownish-ochreous. Maxillary palpi white, towards base 
ochreous-fuscous. Labial palpi moderately long, rather dark ochreous- 
fuscous, white internally and beneath at base. Antenne dark fuscous.
