22 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 tbis description, later described a totally different species of 

 tbe genus from Europe under tbe same name, wbich cannot stand. 



4. Cr. angustipennis, Z. 



(Chilo angustipennis, Z., Hor. Boss, 1877, 15, PL I., 3 ; Chilo leucanialis, Butl., Proc. 



Zool. Soc. Loncl., 1877, 401.) 



Male, female. — 29-44 mm. Head white, sides of crown pale brownish- 

 ochreous. Maxillary palpi white, towards base light brownish-ochreous. 

 Labial palpi very long, white, externally light brownish-ochreous. Antennae 

 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 -J- 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. 



5. Cr. dicrenellns, n. sp. 



Male, female. — 28-32 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. Antennas dark fuscous.
