NOTES ON LEPIDOPTERA. 



On two closely Allied Tarache Larv^— Tarache erastroides, 

 Guen, The description of this larva which I gave on page 8, Vol. I., of 

 " Papilio," also includes the larva of T. candefacta, Hubner. The chief dif- 

 ferences in these two larvae are to be found in the markings of the head ; in 

 erastroides the head is green, mottled with black, brown and whitish ; while 

 m candefacta it is striped vertically with alternate whitish and green lines, the 

 latter sometimes tinged with purple. The food plant of the two species is the 

 same -Ambrosia artemism folia. Two larvae of erastroides pupated about 

 July 24th, ai^d the imagos issued August 5th and 6th. A larva of catidefacta 

 pupated in the latter part of July and the imago issued on the loth of the follow- 

 ing month. I have also found the larvae of catidefacta in the vicinity of Anaheim , 

 California (my present home) ; they do not differ from Eastern specimens, and 

 tha food plant is the same. One specimen pupated August 22. and the imago 

 issued September 5 ; the latter is considerably darker than any of my Illinois 

 examples. D. W. Coquillett. 



Appendages OF LeuCARCTIAACREA. In response to Mr. Stretchs' inter- 

 esting paper on the appendages of L. Acrcea. I would state that so far as known 

 to me, they were iirst observed by the late Mr. C. T. Robinson, who showed me 

 a preparation of them at his residence in Putnam County, N. Y. I believe, also, 

 Mr. Morrison very fully published them in Psyche; I have not his paper to refer 

 to. Mr. Robinson made notes on this discovery, but they were not published ; 

 I have alluded to their existence in Ann, N. Y., Lye. Nat. History. A. R. Grote. 



In the February number of '-Papilio" Mr. R. H. Stretch asks if any 

 Eastern entomologists have found the peculiar abdominal organs of Leucarctia 

 acrcea, Smith, which he describes. While dissecting a male moth of this species 

 in July last, I saw these organs. I afterwards examined many other specimens, 

 and aKvays found them present. I also examined allied species, and found them 

 in Pyrrharctia Isabella, Smith. As I could find no mention of them in any 

 accessible works on entomology. Prof. A. J. Cook kindly took some specimens 

 to the Montreal meeting of the A. A. A. S. He showed them to Prof. C. H. 

 Fernald, who pronounced them to be scent organs. The hairs on the membranes 

 of the appendages in P. Isabella are white. They may be seen in dried speci- 

 mens by dissecting away the upper posterior portion of the abdomen,

Early Appearance of Hyphantria Cunea, Drury. Two specimens 

 of this moth have been taken here this Spring, one on March 19 and the other 

 on April 14. The first was found in the house on a window, while the second 

 was captured out of doors: I think it an interesting and not generally known 

 fact that this insect is to be found so early in the season.
