TWO NEW GEOMETRIDS FROM MR. NEUMOEGEN'S 



COLLECTION. 



By a. R. Grote. 



Chloraspilates Arizonaria. n. S. 



S ? . Fore wings dull green, with the costa ochrey, and two 

 ante-apical costal brown dots in the places of the mesial shade 

 and external line, A minute ringed discal dot. At the place of 

 the sub-terminal line two or three superposed brown dots at 

 costa before apices. Hind wings ochre powdered with red, and 

 with a red mesial line and discal dot. Beneath ochre, irrorate 

 with red. Head ochrey. Thorax greenish. Abdomen ochrey. 

 This seems to be larger than the Texan Bicoloraria, and to differ 

 by the discal marks and absence of external or other lines on pri- 

 maries. The pectinate antennae of the male have also the stem 

 distinctly whitish, as it is in the simple ones of the female. Tuc- 

 son; several examples. Notwithstanding the differences, we 

 may only have to do with a variety. 



EUCATERVA. n. gen. 



Allied to my genus Caterva. 



Male. — Labial palpi of unusual length, extended forwards 

 and upwards, curving slightly. The relatively short third article 

 is of the same thickness with the long, closely scaled linear sec- 

 ond joint. No ocelli. Eyes naked. Front flat. Labial palpi 

 projecting forwards about as far again as the head is long. Male 

 antennje bipectinate, with thick, ciliated branches. 



Female. — Labial palpi shorter ; about half shorter and slen- 

 derer than male. Antennae simple. Body soft and somewhat 

 heavy. 



The vestiture is close and evenly laid on, consisting of flat- 

 ish scales. Wings entire ; both sexes winged. 



EUCATERVA VaRIARIA. n. S. 



$ ? . White. Size of Clcoria PiilcJiraria. The males are 

 white, thickly sprinkled with blackish, with straight outer and 

 curved inner thick mesial lines and discal dot, much the orna- 

 mentation of Glomeraria. Hind wings paler, unlined with dot.
