6 Transactions. — Zoology. 



in tolerable plenty throughout the whole world, the Australian species being 

 numerous and in the main very similar to those found elsewhere. The 

 Galleridcr, a small family of world-wide distribution, are also not found, and 

 the cosmopolitan genera Schamobius, Scirpophaga, Chilo, and Prionopteryx, 

 are similarly remarkable by their absence. 



The above remarks are not intended to express final conclusions, but 

 only to call attention to inferences which seem fairly deducible from the 

 facts known, as a means to the rational classification of the group. 



I desire to acknowledge my great indebtedness in the preparation of 

 these papers to Mr. Fereday, whose very valuable and extensive collection 

 has been freely placed at my disposal in the interests of science ; without 

 his assistance it would have been impossible for me to have treated the 

 subject with any degree of completeness. 



CBAMBIDiE. 



Labial palpi porrected, generally lon^. Maxillary palpi triangular, 

 porrected, conspicuous. Forewings with 12 veins (rarely fewer, but not 

 in New Zealand genera), vein 1 simple, 8 and 9 stalked, 7 sometimes from 

 same stalk. Hindwings with 8 veins (rarely 7, but not in New Zealand 

 genera), 4 and 5 often stalked, 7 and 8 stalked, lower median vein pectin- 

 ated at base. 



In the absence of the PJiycidce, this family is not likely to be confused 

 with any other in New Zealand, except with the group of Scoparia and its 

 allies ; some of these latter approach nearly to Crambus in superficial 

 appearance, but may be invariably recognised by the absence of the basal 

 pecten, or fringe of hairs, on the upper surface of the lower median vein of 

 the hindwings. Care must be taken to note the right vein, as the other 

 veins often bear basal pectinations which are not of the same importance. 



Five genera are represented in New Zealand, which may be thus dis- 

 tinguished : 



A. vein 7 of forewings separate. 



I. vein 11 of forewings coalescing with 12 before costa . . 4. Diptychophora. 



II. ,, ,, ,, separate. 



a. forewings with raised tufts of scales on surface . . . . 2. Cryptomima. 



b. ,, smooth. 



1. female with abbreviated wings .. .. .. ..3. Scenoploca. 



2. „ fully developed .. .. .. .. . . 1. Thinasotia. 



B. ,, ,, ,, rising out of stalk of 8 and 9 . . . . . . . . 5. Crambus. 



1. Thinasotia, Hb. 

 Antennas of male finely ciliated. Labial palpi long, attenuated. Fore- 

 wings with 12 veins, 8 and 9 stalked." Hindwings with 8 veins, 4 and 5 

 stalked or from a point, 6 widely remote at origin from 7, 7 and 8 stalked, 

 cell closed.
