most anywhere the food plant Catalpa occurred and it was a 

 pest in the Nurseries as far north as Eagle Rock. But most 

 of them were infested with parasites. The work of this little 

 insect put a complete check on to this species, and last season 

 very few caterpillars were seen. If the parasite did not do 

 such good work the catalpa sphinx would be a pest to the nur- 

 sery as bad as any insect that they have to contend with, aside 

 from the San Jose scale. 



La para conifer arum: This is a rare species and no speci- 

 mens were taken by me in the last two years. 



Smerinthns geminatus used to be a very common species in 

 Newark, but was very rare in the last two years. 



Paonias excaecatus was very abundant in 1907 but in 1908 

 they took a big drop and not more than fifteen caterpillars 

 were taken by me. Most of the pupae must have died during 

 the winter 1907-08 as very few of the caterpillars taken in 

 1907 were infested with parasites. 



Paonias my ops fared on the whole about as well as excae- 

 catus. 



Paonias astylus : This species is a thing of the past in New- 

 ark, due largely to the elimination of their food plants. This 

 species is more protected from parasites than many of the 

 other species, but has always been counted amongst the rari- 

 ties. 



Cressonia juglandis was not as abundant last year as 

 in former years, but was not at all rare. 



Philosamia cynthia has been common around Newark for 

 many years. Hundreds of the cocoons are collected every 

 Fall, but there seems to be no apparent decrease. Cynthia 

 seems to be very local and only in late years are they spread- 

 ing southward. They are now found at Elizabeth but not 

 further southwest than that city. It looks as if they took a 

 southwest course and are going to follow the coast line. South 

 Amboy is the farthest place south and west from Newark, 

 where it has so far been found in New Jersey. 



Samia cccropia has also been a common species in Newark, 

 there never was much trouble to secure several thousand co-
