Another species which has not been worked out and which is of 

 somewhat doubtful value is Packardia albipuncata. I included this 

 with some doubt, as a synonym of P. gtmiuaia (Jour. N. Y. En t. 

 Soc. , VI, pp. I and 3); but Miss Morton told me last summer that 

 she was now able to distinguish the larvae and that the moths fly at 

 different hours of the night. It is therefore probable that we have in 

 the form a true species, though closely allied to P. gemiiiata. I have 

 not been able to obtain it in recent years, though formerly it occurred 

 to me at Rhinebeck, N. Y. 



Besides these, two other species may occur in New York, at 

 least occasionally. Mr. Beutenmiiller tells me that he remembers to 

 have seen a specimen of Apoda rectilinea which was taken close to 

 New York City and Monoleitca semifascia has occurred at Morris 

 Plains, N. J. (Papilio, III, 25), which is so near to New York as to 

 make it probable that it may occur there also. These two species are 

 essentially southern in their distribution and New York is probably 

 their extreme limit, if not normally beyond their limit. Therefore I 

 shall not delay this article for them ; but I hope to return to them 

 later, and will do so if I should be so fortunate as to secure the larvae. 

 At the most. New York State will have twenty-one or twenty-two 

 species of Eucleida^, the larvae of eighteen of which have now been 

 made known in all their stages in this series of articles. The three 

 species not yet known are included in the genealogical tree in their 

 probable positions, but are not represented as attached to the main 

 stem. (Plate VI, Fig. 6, /, /and q.^ 



Summary of Structural Characters. 



The eggs of all our species are alike, elliptical, flat and very thin, 

 colorless and reticulated, except Phobett-on pitheci'im, which differs in 

 being circular and b:own. Some of the eggs are yellow or almost 

 orange color, but Phobetroii is the darkest. They hatch in periods 

 varying from seven to ten days, rarely fifteen days. The larvje com- 

 prise several structural types whose relations may be briefly defined by 

 the following
