Celmisia lanceolata is intermediate in character between C. coriacea 

 Hook. f. and C. Armstrongii Petrie. It is best distinguished by the 

 large heads, but not so large as reached by C. coriacea, the long narrow 

 rays, the stiff woolly scapes with many leaf-like ensiform bracts, the long 

 dull glaucous or yellowish-green linear-lanceolate leaves in erect rosettes 

 with a conspicuous yellow or even orange midrib and widely recurved 

 margin, the broad pale leaf-sheaths, and the very close silvery tomentum. 



The scape when compressed is about 6 mm. broad ; it is densely 

 woolly with long white matted hairs. The bracts are ensiform, concave 

 on the upper surface, about 11cm. long by 1cm. wide, pale yellowish- 

 green with a brownish-yellow midrib. The involucral bracts are green 

 at the fleshy base but brown elsewhere, ciliate, more or less glabrous else- 

 where, and about 2 - 3 cm. long and 3 mm. wide. 



2. Notes on the Nomenclature of the New Zealand Geometridae; with 



Description of a New Species. 



By L. B. Prout. 



Communicated by George Howes, F.E.S. 



[Read before the Otago Institute, 6th June, 1911.] 



The following extracts from the letters of Mr. L. B. Prout are of con- 

 siderable interest to students of Lepidoptera in New Zealand, as several 

 disputed points are settled here : — 



Xanthorhoe cinerearia Dbld. 



The large form is rightly semisignata Walk., and is a true Xanthorhoe 

 (discocellular veins of the hindwing simple). Its antennae have about 

 28 segments pectinated. 



Synonyms : Xanthorhoe semisignata Walk. = semilisata Walk. = 

 corcularia Guen. = dissociata Walk. = punctilineata Walk. 



The small form is cinerearia Dbld., but is a Larentia (discocellulars 

 triangulate), and has about 22 segments pectinated. 



Synonyms : Larentia cineararia Dbld. = diffusaria Walk. = infusata 

 Walk. = invexata Walk. — inoperata Walk. = infantaria Guen. = ado- 

 nata Feld. 



Larentia farinata Warr. 



L. farinata is of a more unicolorous slaty grey (not brownish-grey) 

 than cineararia, and is larger and more weakly marked. About 21 seg- 

 ments of the antennae are pectinated. Its proximal areole is minute, 

 but this may vary. 



An excellent description, from Wellington specimens, is given in 

 " Novitates Zoologicae," vol. 3, p. 388.
