country. The females are very rosy in color and must be very similar to Tiualapai Neum., but 

 on the fore wings both the lines are distinct. The males vary considerably in the amount of 

 rosy tint on the wing, most of them being largely brown. — Dyar, t. c] 



HEMILEUCA LARES Druce. 



{Euleueophseus lares Deuce, Biol. Cent.-Am., Lep. Het., II, 420, 1897. 



This is known to me only by Druce's figure. It is described from a single male from Durango 



City. This is on the western edge of the high table-land, in a climate similar to that of Arizona 



The species should be intermediate between mania and Tiualapai, but unfortunately only the 



male of lares is known and only the female of Tiualapai, so that no useful comparisons can be 



made. — Dyar, t. c] 



HEMILEUCA NUMA Druce. 



[Euleucophxus numa Druce, Biol. Cent.-Am., Lep. Het., II, 421, 1897. 



Described from Mexico City. I have specimens from there (Schaus collection) and also 



others sent by Mr. Miiller from the same locality. The high table-land centering hi the vicinity 



of Mexico City is evidently the stronghold of the species of Hemileuca of the grass-feeding 



group. — Dyar, t. c] 



HEMILEUCA NITRIA Druce. 



[Euleucophxus nitria Druce, Biol. Cent.-Am., Lep. Het., II, 421, 1897. 



Described from "Mexico" without definite locality. I have no specimens of the species. 

 It is apparently closely allied to numa, and may be a variety of that. Its relations can not be 

 well discussed without more definite knowledge of the exact locality. — Dyar, t. c] 



HEMILEUCA HUALAPAI (Neumcegen). 

 Plate LXVII, fig. 5. 

 [Euleucophxus hualapai Neumcegen, Papilio, III (1883), p. 138.] 



9 . Antennae pectinated; pale flesh rose, uniform, with no markings whatever [except], a 

 slight linear discal streak; costa yellowish; fore wing rather broad; southwestern Arizona. 

 [Note doubtless based on examination of type.] 



[Known only by a single female from southwestern Arizona. In the absence of fresh 

 material, we have only the original description to go by, which indicates that the species is not 

 the same as olivise. The costa is stated to be bright yellow, which is not the case in the femaje 

 olivise, although there is considerable ocherous shading ha some specimens. The whole insect 

 is described as being very pale and rose colored. — H. G. Dyar, in Ainslie, 1910.] 



[Mr. J. Doll informs me that the type specimen of Tiualapai was coUected by Morrison. 

 The fore wings are less pointed than in H. sororia, and the stigmatic spot is as in olivise, not 

 as in sororia. On the other hand, sororia and olivise have rather similar markings, while Tiualapai 

 looks quite different.] 



[We have a single <? specimen received from Geo. Franck, of the Am. Ent. Co., purporting 

 to come from Chiricahua Mountains, Arizona, but it seems probable that it is really mania 

 Druce from Mexico, as the banding is strong on primaries. — J. McDunnough.] 



HEMILEUCA MARTLLIA Dyar. 

 Plate LXI, figs. 7, 8. 



[Rosy brown to dull rose color. Thorax rosy brown with whitish overcast. Fore wing 

 with the costa more or less marked with whitish, but no ocherous; lines broad, distinct, whitish; 

 discal mark narrow, whitish, obscure. Hind wing rosy brownish hi both sexes, with an outer 

 whitish diffused line. Beneath the lines faintly reproduced, the basal part of the fore wing red. 

 Abdomen dark rose-red. Expanse: Male 50 mm.; female 60 mm. 



Two males, two females, Tehuacan, State of Puebla, Mexico (R. Miiller, No. 1753). 



Type. — No. 12932, United States National Museum.
