NEW SPECIES AND GENERA OF GEOMETBJDAE 

 IN THE TIUNG MUSEUM. 



By W. WARREJSr, M.A., F.E.S. 



Suiii-AMiLY OENOCHROMINAE. 



Adelotypa gen. nov. 



Forewings: with costa straight, or even slightly conca\e, except before ai)e.x, 

 where it is shortly convex; apex blunt; hiiulmargiu curved, more strongly towards 

 anal angle, which is well marked. 



Ilimlwiw/s: with rounded hindmargin, and aual angle slightly produced. 



Palpi i)orrect ; tongue ? Antennae of ? filiform. 



Neuraiioii: cell about half as long as wing; discocellular indiscernible. 

 Forewings, first median at three-fourths, second and third together from lower end of 

 cell ; lower radial from centre of discocellular space ; upper fi-om top end of cell : one 

 subcostal absent ; the last two on a joint stem from just before end of cell, the other 

 two free. Hindwings with costa strongly shouldered at base; costal vein arched 

 upwards from base away from subcostal, and terminating half-way along the costal 

 margin ; two subco.^tal nervules from top end of cell ; radial from centre of disco- 

 cellular space ; medians as in forewings. 



Type : Adelotyjja xanthohrunnea ^^'arr. 



The jwsition of this genus is uncertain and eqiuvocal. The radial of the hindwings 

 is distinct ; the arching of the costal vein and the direction of its course are both 

 peculiar; I can detect no bar between the costal and subcostal, as in the OrthoslLcinae, 

 and am therefore obhged to refer it to the Oenoc/irominae, notwithstanding the 

 almost entire difference in its superficial appearance. 



Adelotypa xauthobruniiea sp. nov. 



Forewinc/s : rather deep yellow, with the base, the costa to near the middle, and 

 the hindmargin broadly dull chestnut brown ; this marginal region is bounded 

 internally by a curved deeper brown shade, and a similar deeper shade is discernible 

 immediately before the hindmargin, and reaches quite to the anal angle, whereas 

 the marginal fascia itself is interrupted bolow the submedian fold by the yellow 

 ground colour. 



Hindwings : rather deeper yellow, with a chestnut brown apical patch, and a 

 smaller one at the anal angle; fringes and basal line of fringes in both wings 'bro«-n ; 

 base of fringes paler. 



Head, thorax, and abdomen (mouldy) probably brown. Underside like ujiiier, 

 Imt the yellow much paler, with three irregular curved series of deep yellow oblong 

 spots ; tlie edges of the marginal brown band more distinct as a series of browner 

 lunulate spots. 



Expanse of wings : 30 mm. 



One ? from South America (? Chili.)
