NOTE ON LARVAE OF GYNAEPHORA 

 GROENLANDICA AND G. ROSSII. 



BY HARRISON G. DYAR, WASHINGTON, D. C. 



In Psyche vii, 32S I lefened to Curtis' 

 description of the larva of i«;-z'a rossii-\nA to 

 the fact that it did not correspond with the 

 larva of rossii \s\\\c\\ I found on the summit 

 of Mt. Washington. The U. S. National 

 museum has just received two larvae from 

 West Greenland, north of Wilcox Head, col- 

 lected by R. Stein, which agree with Curtis' 

 brief description. One had pupated and I 

 obtained from it a moth of G. gioenlandica. 



Therefore Curtis must have mixed the 

 species, describing the moth of rossii and 

 larva of groenlandica. Apparently both 

 species occur in Greenland. The museum has 

 specimens of rossii from the Florence Arctic 

 expedition and groenlandica from Polaris 

 Bay. The species are probably not coexten- 

 sive, however, as only rossii has been taken 

 on Mt. Washington. We have it also from 

 Labrador and Point Barrow, Alaska (Mur- 

 dock). As to the larva described by Dr. 

 Packard, his " half grown larva " is probably 

 groenlandica ; the "full fed" one is unlike 

 either. 



Larva of G. groenlandica : Head 3.4 mm. 

 wide (male), rounded, dull black, densely 

 covered with long secondary black hairs. 

 Body entirely black, the warts large and 

 granular, arrangement apparently normal 

 with i and iv small, but I cannot see them 

 distinctly in the shrunken specimens. Re- 

 tractile tubercles on joints 10 and 11 whitish. 

 Hair abundant, dull reddish brown, mixed 

 with black. Dorsal tufts present on joints 

 5 to 9 and 12 as in D. selenitica., but those 

 on 5, 6 and 12 black, on 7, 8 and 9 deep 

 orange. The black tufts are a little longest, 

 projecting beyond the orange hairs and a 

 little beyond the average of the general 

 dorsal coating. Hairs all finely spinulated 

 none plumed. 



The smaller specimen has the head 2., 

 mm. wide. 



The pupa resembles that of rossii, but the 

 long dorsal hair is more erect and black, not 

 whitish ; the shell is thicker, black, and 

 possesses three pair of long but functionless 

 appendages in the place of the abdominal 

 legs of joints 8 to 10 which I do not find in 

 the pupa of rossii. 



DATES OF ISSUE OF SOME OF BOIS- 

 DUVAL'S WORKS. 



by SAMUEL H. SCtDDER. 



The following data regarding the time of 

 issue of some of the works of the French 

 entomologist, Jean Baptiste Alphonse Bois- 

 duval d'Echauftbur (b. iSoi, d. 1S79) may 

 prove of interest to special students. They 

 were partly gleaned from ditTerent sources in 

 Paris many years ago, partly obtained by- 

 reference to the Bibliographie de la France. 



The Icones historiques des Lepidopteres 

 d'Europe appeared in 42 livraisons between 

 1832 and 1S43, according to Hagen. The 

 Prospectus was issued March 17, 1832. The 

 separate livraisons contained each, as far as I 

 have discovered, from 8-20 pp. of text and 2 

 plates. Livr. i, 2 appeared Mar. 24, 1S32; 

 3, 4, Mar. 31, 1S32 i 5, 6, July 7, 1832 ; 7, S. 

 Oct. 13, 1832; 9, 10, Jan. 5, 1833; (11-18 not 

 discovered, but doubtless in 1833; ! '9' -°' 

 Jan. 4, 1834; 21, 22, July 26, 1S34; 23, 24. 

 May 17, 1834; 25, 26, 27, 28, July 26, 1S34; 

 29, 30, Sept. 27, 1S34; 31, 32, Jan. 17, 1835; 

 of the remainder I have no memoranda, 

 except that livr. 38 was published in the last 

 quarter of 1835. After 1S35 there is no men- 

 tion of it in the Bibliographie de la France. 



The Europaeorum Lepidopterorum index 

 methodicus appeared Nov. 22, 1S28; it is 

 given as 1S29 in Hagen. The 2d ed,, entitled 

 Genera et index methodicus europaeorum 

 Lepidopterorum, appeared May 9, 1840. 



The Faune entomologique de Madagascar 

 appeared Sept. 28, 1S33: given by Hagen as 

 1834.
