‘In the year 1900, Dr. Dyar exhibited two of these nests, 
which had been sent to Washington by Dr. Alfredo Dugés, of 
Guanajuato, Mexico. Dr. Dyar at the same time showed 
specimens of the larva, of which he has published a minute 
description (Proc. Ent. Soc. Washington, vol. iv, 1901, pp. 419, 
420). The food-plant was stated to bea species of Arctosta- 
phylos. In the discussion which followed this exhibit, Dr. 
Dyar said that this was the only social butterfly known to 
him. It is no doubt rare in the extreme for the gregarious 
habit and the construction of a common abode to be carried so. 
far in the case of butterflies as in the present example, but 
there is possibly at least one other instance to be found 
among the Pierines. I refer to NVeophasia terlootii, Behr, 
which also inhabits Mexico and Arizona, and is stated by its 
describer to feed on an Arbutus, the larve forming common 
habitations in which they pupate gregariously. I cannot, 
however, avoid the suspicion that the nest of Hucheira has 
by some mistake been attributed to Neophasia, though the 
testimony of Behr with regard to J. terlootiz, originally pub- 
lished in 1890 and repeated in a letter to Dr. Skinner in 1900, 
certainly appears to be explicit enough, This latter butterfly 
is especially interesting as possessing a female which closely 
resembles some of the mimetic forms of Huterpe. (See Proc. 
Calif. Acad. Sci., 2nd series, vol. 11, 1890, p. 91; Ent. News 
of Philadelphia, vol. xi, 1900, pp. 331, 413, 533, Pl. IT, fig. 
28, and Pl. XIV.) Iam not aware that the method of pupal 
suspension in this species has been recorded, but the pupa of 
the other species of Veophasia, viz. V. menapia, Feld., is stated 
by H. Edwards to be invariably attached with the head up- 
wards. (Proc. Calif. Acad. Sci., vol. v, 1875, p. 165.) Behr 
is of opinion that the two known species of Veophasia should 
be referred to the genus Hucheira ; this, as I have elsewhere 
stated (Trans. Ent. Soc. Lond., 1904, p. 304), seems to rest 
on insufficient evidence, though there is doubtless some 
affinity between the two genera, and both belong to an early 
Pierine stock. When the life history of the primitive Pierines 
(Metaporia, Pontia, etc.) of Central Asia is better known, it 
will be interesting to see whether the social habit and com- 
munity of larval shelter will be found to prevail with any of
