64 CEKEAL AND FOKAGE INSECTS. 



Hemileuca hualapai Neumoegen. 



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 spe- 

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

 case in the female olivise, although there is considerable ochreous shading in some speci- 

 mens. The whole insect is described as being very pale and rose colored. While it is 

 impossible to decide the exact specific standing of the form from the description of one 

 female specimen, it seems best at present to consider it a distinct species. 



Hemileuca mania Druce. 



Described from Orizaba, Mexico. We have specimens from Mr. Muller, collected 

 in Motzorongo, both localities in the State of Vera Cruz in the hot, moist country. The 

 females appear very similar to the description of hualapai, being pale rosy with a bright 

 yellow costa. 



Hemileuca lares Druce. 



This was described from Durango City, which is on the high tableland at the foot of 

 the Sierra Madre. No specimens are before us, the species being known to us by 

 Druce's figure. 



Hemileuca numa Druce. 



This was described from Mexico City. We have specimens from there in the Schaus 

 collection and others sent by Mr. Muller. 



Hemileuca nitria Druce. 



This species is evidently very close to numa. We have no specimens, and the 

 original type is without definite locality. Probably it came from somewhere on the 

 Mexican tableland. It may even be not specifically distinct from numa. 



Hemileuca olivise Cockerell. 



The present species falls here in general relationship, being apparently most nearly 

 allied to the three following. 



Hemileuca sororia Hy. Edwards. 



As stated above, known only from the original type specimen from La Paz, Lower 

 California. 



Hemileuca. marillia Dyar. 



Described from Tehuacan, State of Puebla, Mexico, on the southern end of the Mexi- 

 can plateau. Closely allied to the following. 



Hemileuca lex Druce. 



Described from a single male from Durango City, from the western edge of the cen- 

 tral part of the Mexican plateau. 



It will be seen that, of the 12 nominal species above, 8 are from the 

 Mexican plateau (including 2 without exact localities), 6 from the 

 lower and best known part of that region in the vicinity of Mexico 

 City, and 2 from the central portion in the State of Durango. Of 

 the outlying 4 forms, 1 is known from the peninsula of Lower Cali- 

 fornia, 1 from southwestern Arizona, and 2 from New Mexico, while 

 but a single species occurs outside of the high dr} r prairie region, 

 namely H. mania Druce, from the State of Vera Cruz, which is
