ADDENDA 



Since the above went to press we have received some interesting 

 information concerning the habits of several Arizona species from 

 our collector, Mr. M. Chrisman ; we append this under the various 

 specific heads. 

 M. YuccAE coLORADENSis Riley. 



Quite local; a strip of black lime country (2-10 miles) between 

 3,000-4,000 ft. elevation. The S is rather shy and flies only in the 

 bright sunshine, mostly along dry washes ; the mating time is probably 

 early morning and females are seldom seen on the wing after 4 p. m. 

 The main flight occurs in March and April, but specimens have been 

 seen as early as Feb. 7th. 

 M. URSus Poling. 



No specimens have been observed since 1903; between 1901-1903 

 some 8 or 10 specimens were observed in the beginning of September, 

 all flying in the hot sunshine from 11 a. m. to i p. m. Of these only 

 the two mentioned previously were captured. The elevation was 

 about 4,500 ft. 



M. NEUMOEGENI Edw. 



All over the Santa Catalina Mts. from 3,000 to 6,000 ft. on the 

 hill tops and south and east slopes ; the males may be captured in mid 

 September on damp patches of ground in sandy washes; they are on 

 the wing morning and afternoon, avoiding the hot mid-day sun. Flight 

 occurs from the first week in September until well into November, in 

 fact until the first snow-fall, the 9 's appearing considerably later in 

 the season than the 3 's. 

 M. POLiNGi Skin. 



Rather local ; found only between the Catalina and Rincon Mts. 

 wherever Amola plants (Mexican soap-weed) occur. Prefers the 

 north and northeast slopes, flying seldom on the hill tops or in the 

 canyon bottoms. Flight of the £ between 8 a. m. and 2 p. m., of the 

 9 from II to I o'clock; occurs in September and October but is most 

 numerous from Oct. 6th to 15th; the S is very rapid in its flight but 

 easily caught while resting on rocks or ground. Mr. Chrisman states 

 that while he has caught no 9 's in the actual act of oviposition he has 

 come so near to it that he is satisfied that the eggs are deposited singly 

 near the base of the leaves of the Amola plant; traces of larvae have 

 been met with in the roots, although none have been actually dis- 

 covered.
