V of the secondaries as well developed as any other, and 

 asising from tlie median vein close to IV. It is therefore typically quadrifid, 

 although differing altogether in habitus from the quadrifid section of the more 

 typical Nociuidae. The habitus is rather that of the Notodontidae and some of 

 the species resemble these very closely in type and maculation. Other Notodoniid 

 characters are the short, rather weak, thorax, tlie longer, cylindrical abdomen of 

 the female, the retracted liead in which the tongue tends to become aborted and, 

 except in Meleneta, the pectinated antenna- of the male (and sometimes female) 

 in which the joints are short and the branches in consequence arc very closely 

 approximated. All the genera typically referred here have hairy eyes, and this 

 combination of venation, hairy eyes and Notodontid habitus, makes the sub-family 

 an easily recognizable one. 



Four genera are recognized in tlic Anuricaii fauna, nortli of Mexico: 

 Tongue short and weak, useless for feeding. 



AntenniP pectinated in the male, simple in tlie female. 

 Primaries trigonate, inner and outer margin 



approximately equal in length. Panthea 



Primaries more abruptly widening at base; ajjices more obtuse; 



inner margin longer than outer. Demas 



Tongue moderate, useful for feeding. 



Antennae pectinated in both sexes ; though shortly in female. Charadra 



Antennae merely thickened in the male. Meleneta 



Demas has no representative on the Pacific Coast so far as we know at the 

 present time, all but one of the species thus far known occurring on the Atlantic 

 slope. Demas palata Grt. occurs in Colorado and Arizona, and it is not unlikely 

 to occur in Southeastern California. It is easily the prettiest species of the genus 

 with its clear black and white powderings, and the narrow black lines that resemble 

 the ornamentation in Raphia most nearly. 



Panthea is, on the whole, more northern in distribution, and extends to the 

 Pacific Coast: P. portlandia Grt., having been taken in Oregon and Washington, 

 as well as in Vancouver and elsewhere in British Columbia. It is not improbable 

 that this species also will be found in Northern California and it may be differ- 

 entiated from the other si^ccies of the genus by its whitish gray, ground color, the 

 transverse lines broad and diffuse, and the reniform spot obvious. 



No representative of the genus Charadra has been taken nearer than Texas, 

 nor is it known from any point west of the Rocky Mountains. 



The Charadra decora Morr., described from California, is Mexican, but may 

 occur in Lower California and almost certainly does in Arizona. 



Meleneta is from the Huachuca Mountains in Arizona, and may perhaps oc- 

 cur in the desert areas of Southern California. The habitus and type of 

 maculation is somewhat as in Charadra, or rather intermediate between that and 

 Raphia. 



Raphia Hbn. 



For convenience the genus Raphia may be considered here because of its 

 habitual and even structural resemblance to the other genera more strictly referred
