NOTES AND DESCRIPTIONS OF GEOMETRIDAE. 



By W. S. Wright, 

 San Diego, California. 



Platffia californiaria pasadenaria new subspecies. 



Expanse 34 mm. 



Palpi, head, antennae and thorax as in P. californiaria U.S. Color less 

 deep, being a much browner brown. Lines the same except that the angles 

 are much sharper and deeper ; the course of the first line from costa to sub- 

 median is wavy rather than indented or toothed as is often the case in cali- 

 forniaria. The color is much more evenly laid, the wing surface having a 

 much less speckled appearance. Beneath, the primaries are strongly irrorated 

 along the costa but smooth on the disk or with very faint irrorations, the 

 lines showing through faintly. The secondaries are white, much irrorated, 

 with a strong extra-discal brown line angled on the fold and on vein 2, a 

 submarginal line parallel to the first, both having a whitish shade on the 

 outer side much the same as in californiaria, but the angles sharper and the 

 line more evident than in most specimens of the former species. Discal dots 

 rather prominent. 



Holotype male, Pasadena, Cal., May i, 1902. 



Allotype female, Pasadena, Cal, April 10, 1902. 



Paratypes, 5 males, 4 females, Pasadena, Cal., April and May. 

 In American Museum of Natural History and author's collections. 



The differences between californiaria and pasadenaria are most 

 noticeable when series of the two are placed side by side; they then 

 become quite as prominent as the differences between californiaria 

 and Icssaria Pearsall. What particular conditions about Pasadena that 

 would favor the evolution of a local race of this insect are unknown 

 to me. unless it might be that the climatic and floral conditions are 

 more favorable to the fullest larval development therfe than at San 

 Diego, Cal., from which place practically all the known specimens 

 of californiaria come. Pcrsonaria Hy. Edwards, the type of which 

 is in the American Museum collection, comes from the high Sierras 

 and is much closer to californiaria than is this new form. 



Pherne subpunctata vemalaria, new form. 



Male. — Expanse 32 mm. 



Primaries : Basal area gray, slightly ochreous. First line narrow, ochrtous 

 with dark brownish gray shade beyond, sharply angled to subcostal, thence 

 perpendicular to inner margin, with a very slight curve near the end of the 

 line. Mesial band mouse-gray with a tinge of ochreous. Extra-discal line
