that I was unable to get any for my collection. I did man- 

 age to get a half dozen at Barnegat City. In former years 

 thousands of specimens could be seen almost everywhere. 

 The cause of such a decrease in numbers must be attributed 

 to parasites or disease of the caterpillars. 



Chrysophanns thoe: This is a local species and not at all 

 common. Several trips were made to the breeding places of 

 this species in the last two seasons, but no sign of any were 

 seen. 



Chrysophamis cpi.vanthe : Although this species is record- 

 ed from New Jersey I have never been successful in finding 

 any. 



Pieris rapae was, as usual, quite plentiful throughout the 

 State. 



Anthocharis genutia: This species has been quite com- 

 mon ever since they were discovered on the Garrett Moun- 

 tains near Paterson, and several hundreds were taken every 

 season by the Newark, New York and Brooklyn collectors ; 

 but last year there was a general scarcity and the stock in 

 the collectors' boxes is now rather low as compared with for- 

 mer seasons. 



Colis philodice: This species was as plentiful as ever. 



Terias lisa was quite rare in late years, but last season this 

 little creature could be seen wherever its food plant occurred 

 and in many places in goodly numbers. 



Danias plexippus was common throughout the State. 



Euptoieta claudia was common throughout the State and es- 

 pecially near Elizabethport at the edge of the salt marsh. 



Argynnis idalia was rare compared with other seasons. The 

 species was very common in 1900. In that year no less than 

 five hundred specimens were taken by me in three days at Hil- 

 ton, N. J., and fully half of them were females. The reason 

 so many were taken is that their breeding place was being 

 destroyed. One hundred and sixty females were taken in cop- 

 ulation, and half of these females were liberated in another 

 section of the State where the food plant (Violets) was in 

 abundance. This seemed to be an out of the way place for this
