^0.3.] GROTE ON MOTHS OF MAINE. 589 



aud 7nyron, so plentiful was insect life before the English sparrows 

 came. Thyreus Ahhotii was so common that its large larvae could be 

 found almost by the hundred. The nativ^c birds were undoubtedly di- 

 minished by the attacks of domestic animals and boys, to allow of such 

 a multiplication of cateriiillars. I think those were golden days for the 

 Lepidopterists, looking back on them now. How much their bright- 

 . ness in retrospect owes to other causes, in my own case, is a matter of 

 trite philosophical inquiry and conclusion. 



LARV-/E AFPEGTINa THE PINE. 



Citheronia sepulcralis Grote. 



This large moth was found on the yellow pine, in the larval condition, 

 by the late Mr. James O. Treat, in Massachusetts. On an unpublished 

 l)late, painted by Abbot, the moth is represented, but not the earlier 

 stages of the insect. This plate is in the British Museum Collection. 

 The moth has been reared in numbers by Mr Koebele in Florida. In 

 all stages it is as distinct from regalis, as any two forms in one genus can 

 l)0ssibly be. I notice it here, to correct a remarkable statement by Dr. 

 Packard in his excellent and very useful Eeport on Insects injurious to 

 Forest and Shade Trees, that it may be a variety of regalis. It has been 

 found not uncommonly about Atlanta, Ga., and, I believe, on small per- 

 simmon bushes as well as the pine. Specimens reared by a collector 

 there, were forwarded to a well-known collector of Beading, Pa. There 

 can be no doubt that the species are abundantly distinct. I collected a 

 very few C. regalis larvse about Atlanta on the cotton plants. The two 

 larvte differ on comparison ; that of regalis is differently colored, larger, 

 and with longer horns. In my opinion there is no doubt of their distinct 

 character. 



Tetralopha diluculella Grote. 



This species infests the terminal twigs of the pine in its larval state. 

 Professor Comstock gives a descrii>tiou of the larva and pupa collected 

 in Florida on Pinus tceda. The insect is found as far north as ]!Srew 

 York. I have given a scientific sketch of the group to which I reler this 

 species and its genus. It is a new subfamily of Pijralida', which I call 

 EiyipascMw^ alter the typical genus founded by the late Dr. Clemens. It 

 is chiefly characterized hy a basal tegumentary extension to the male 

 antenna. 



Pinipestis Zimmermani Grote. 



I have described the larva and moth of Pinipestis Zimmermani^ Grote, 

 in the Bulletin of the Geological Survey, Yol. lY, Xo. 3. The genus 

 may not be distinct from Dionjctria ; but the European moth has not 

 the raised scales on forewings, and the neuration varies sonu'what. I 

 dug out from pine trees these larva^ in the winter; and at dilferent times 

 Mr. Zimmerman, of Erie County, New York, who first drew my atten- 

 tion to the insect and for whom I named it, brought me specimens.
