O.t/ 



Typophorus canellus lahr. 



A small, roundish, brown and lila<k niarkf<l or Mat k h^-etlc aliont ',,,-, inrli long 

 occurs on butternut, mountain ash and \arious plants in Mav and during early fall. 



This species is a variable one, as is illiistrateil hy I )r Horn's ke\' for 

 the separation of 14. varieties. It has becMi lakt'n \>y Mr N'oiiul^ on butter- 

 nut, mountain ash and such low plants as 

 strawberries iruMay, and on the heathlike 

 aster, Aster e r i c o i d e s, the last of 

 August and the first of September. It eats 

 irregular, oval or elongate holes in almost 

 any part of mountain ash lea\es and occa- 

 sionally causes considerable injin-\. Mr 

 Young is of the opinion that a similar form 

 occurring on low plants, may be different 

 from that mi-t with on trees, though at present he is not able to detect con- 

 stant differences. This species, according to Dr Morn, is widclv distributed 

 over the continent east of the Rock\- moimtains, occurring- from Kansas to 

 Texas, west throusfh Arizona to I""orl ^'un^a.

Green-Striped maple worm 



A)iiso(a riihiiunda babr. 



A large, pale yellowish green larva striped with darker green, occurs in midsummer 

 on maple trees. 



This species is generally distributed throughout the State, though 

 rarely abundant enough to cause serious mischief. Tlu; late I )r Lintner, 

 however, records an instance of this lar\a occurring in large lumibers in 

 Monticello, .Sullivan co., where it defoliated a nuiiiber of soft majjletrees. 

 This species is much better known as a ])esi in the Western .States, where 

 it frequently strips the leaves from large numbers of majjles. It feeds on 

 the sugar mai)lc as well as the soft maple.
