Meyeick. — On Neiv Zealand Geometrma. 67 



Masterton, Wellington, Nelson, Ckristchurch, Mount Hutt, Duneuin, 

 and probably throughout the islands ; on tree-trunks, fences, rocks, etc., 

 from November to March and in June, resting with the wings expanded as 

 in Eupithecia; eighty-four specimens. 



Section D. 

 14. Tatosoma, Butl. 



Face smooth. Palpi long, straight, porrected, shortly rough-scaled, 

 terminal joint short. Antennae in male simple, stout, gradually dilated 

 from base to near apex, apex attenuated. Abdomen in male very exces- 

 sively elongate. Hindwings in male deeply excised near inner margin, 

 inner marginal lobe folded into a long pocket, fringed with hairs. Fore- 

 wings with vein 6 rising out of 9, 7 from or above angle of areole, 10 anas- 

 tomosing moderately with 9, 11 anastomosing moderately with 10, 12 free. 

 Hindwings with veins 6 and 7 separate, 8 free, united with 7 before trans- 

 verse vein by an oblique bar. 



This singular genus is a remnant of a widely diffused but now fragmen- 

 tary group, to which belong also Lobophora (Europe), Rhopalodes (South 

 America), Sauris (Ceylon), and Remodes (Borneo). In all the hindwings of 

 the male are peculiarly modified, usually much diminished in size, and with 

 inner margin formed into a distinct lobe, the object of which is unknown. 

 A similar structure is found only in one or two genera of Tortricina. Rho- 

 palodes is the nearest genus to this, but .vein 5 is said to be obsolete, and 

 the lobe does not form a pocket ; in Sauris the areole is simple, and the 

 antennas thickly scaled ; in Remodes the areole is also simple, the antennae 

 flattened and scaled, and the inner margin is furnished with three super- 

 posed lobular folds, so that it represents the extreme of development in 

 this direction. 



Note. — As terminations in -soma are often erroneously regarded as 

 neuter by entomologists ignorant of the classical languages, it may be 

 worth mentioning that such names as Tatosoma, Leptosoma, etc., can by 

 their formation be nothing but the feminine of adjectives.
