GEOMETRIDAE 



HEMITHEIINAE 



Racheospila irregularia sp. nov. 



Palpi and front dull red-brown ; a white fillet between antennae edged 

 posteriorly with red ; collar and thorax green ; abdomen green dorsally with 

 four large raised white spots ringed with red, anal segment white, beneath 

 white; legs white, fore coxae green-tinged. Primaries bright green with nar- 

 row white costa ; t. a. line white with prominent outward angle in submedian 

 fold ; t. p. line very irregular and strongly dentate, straight from costa to above 

 vein 4, strongly bent outward across veins 3 and 4 with teeth on the veins, bent 

 back sharply to the submedian fold with tooth on vein 2 and then perpendicular 

 to inner margin; a small black discal dot; a narrow red terminal line broken 

 by white dots at ends of veins; fringes white, faintly red-tinged opposite veins. 

 Secondaries similar in maculation to primaries with the same irregular t. p. 

 line. Beneath whitish slightly green-tinged with faint red terminal line. Ex- 

 panse 19 mm. 



Habitat; Brownsville, Texas (May, June). 2 2. Types, Coll. Barnes. 



Belongs in Section II of Racheospila as defined by Prout ; appar- 

 ently related to texana Hist, but with much smaller discal dots and 

 more irregular t. p. line. 



Nemoria aemularia sp. nov. 



Palpi ochreous tinged with ruddy ; front dull pinkish-red with white inter- 

 antennal fillet ; thorax and collar green ; abdomen with basal segments green, 

 terminal segments whitish, with a narrow broken dorsal line of ruddy-brown 

 in the S and a broad band of same color in ? which practically displaces 

 all the green color; abdomen beneath and legs pale ochreous; primaries pale 

 blue- or yellow-green, heavily and roughly striate with pale creamy, veins 

 outlined in creamy ; costa cream colored, ruddy at extreme base ; t. a. line 

 faint, creamy, rounded, partially hidden by the striations ; t. p. line broad, 

 creamy, almost parallel to outer margin ; fringes creamy with slight yellow 

 tinge ; secondaries similar to primaries in maculation. Beneath whitish, partly 

 hyaline. Expanse $ 23 mm., 9 25 mm. 



Habitat: Paradise, Cochise Co., Ariz.; Palmerlee, Ariz. 5 S, 4 9. 

 Types, Coll. Barnes. 



The species is hardly a typical Nemoria, the 9 palpi being longer 

 than usual and more as in Racheospila; as however it appears to be 

 otherwise obviously related to viridicaria Hist, and caenilescens Prout 

 we place it in this genus. Its yellow-green coloration with veins out- 

 lined more or less in ochreous is characteristic.
