Cerura nivea race niveata nov. 



The Arizona race of nivea, which is commonly identified as nivea, and 

 which probably will show intergrades to true nivea, is another large, broad- 

 winged form, but may be distinguished from true nivea by the possession of 

 more or less distinct maculation. The heavy transverse band is somewhat con- 

 stricted on the median vein and in one specimen broken into two patches ; the 

 t. a. is composed of five dots; the t. p., a distinct line of dots; apical-s. t. dots 

 on the outer margin of both primaries and secondaries. 



The authors are inclined to associate nivea and niveata more 

 closely with scolopendrina than with cincrea, because of the antennae 

 and habitus, but the possession of five dots forming the t. a. line, in- 

 stead of four, apparently allies niveata with cincrea. Tentatively, the 

 authors would list the described form of nivea as follows: 



5'. nivea Neum., So. Utah. 



a. — niveata nov., So. Ariz, 

 b. — meridionalis Dyar, Texas. 



Type localities and number and sexes of types: Holotype $, Allotype 9, 

 and 3 $ Paratypes, "So. Ariz." (Poling) ; 1 9 Paratj^pe, Douglas, Ariz. 



LIPARIDAE 



LiPARis Ochs. 



Type L. monacha Linn. 



1810, Ochs., Schmett. Europ., Ill, 186, lists morio, detrita, rubea, monacha, 



dispar, salicis, "v. nigrum" (nivosa), citrysorrhoea, auriflua. 

 1892, Kirby, Cat. Lep. Het., I, 475, lists as preoccupied under Porthetria. 

 1892, Hamp., Fauna Br. Ind., Moths, I, 459, lists as preoccupied, under 



Lymantria. 



1922, Swinhoe, Ann. & Mag. N. H., (9), X, 450, type designated monacha. 



1923, Swinhoe, Ann. & Mag. N. PL, (9), XI, 424, type designated monacha. 



Apparently Liparis Ochs. has been sunk as a homonym of Liparis 

 Artedi, a pre-Linnean genus, (1738). 



Porthetria PIbn. 



Type P. dispar Linn. 



1820, Hbn., Verz., Bek. Schmett., p. 160, lists lunata, dispar, heatrix, hrotea. 



1892, Kirby, Cat. Lep. Het., I, 475, type designated dispar. 



1892, Hamp., Fauna Br. Ind., Moths, I, 459, lists as synonym of Lymantria. 



1923, Swinhoe, Ann. & Mag. N. H., (9), XI, 424, type designated dispar.
