no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 119 



[Mr. T. Pergando records in the books of the Bureau of Entomology that on August 2, 

 1S89, two larvae were received from G. H. Kruschke, Dcnster, Wis., reported as feeding on 

 cranberry. They resembled H. maia, but appeared to differ in the shorter, barbed spines and 

 darker color of the body. The ground color dorsally was dull black or very dark purplish black, 

 with a much interrupted white mediodorsal stripe, divided along the middle by a black line, 

 a much interrupted subdorsal white lino and a broad whitish lateral stripe, inclosing the stig- 

 mata. Stigmata, pale buff with black annulus. Warts, dark red, those of dorsum somewhat 

 paler. All branched spines and those on warts just above and below stigmata, black, tipped 

 with white, those of the two dorsal rows orange tipped with black. Head, reddish brown. 

 These larvae did not produce moths, but Mr. Kruschke sent two pupae "which he found in the 

 dams, which no doubt belong to this species." The pupae were remarkable in that the cremasters 

 of both were without a trace of hooked spines, which are so strong and conspicuous in H. maia. 

 They both produced crippled moths, which Mr. Pergande could not separate from maia. The 

 specimens were also examined by Dr. Dyar.] 1 



HEMILEUCA MAIA var. LUCINA Henry Edwards. 

 Plate LX, figs. 10, 11. 



[The original description of lucina (Ent. Amer., II, p. 14) is as follows: A form occurring in 

 Maine, and probably in other of the northern portions of our continent, which appears to deserve 

 at least a varietal name. It is intermediate between H. maia and H. nevadensis, having the 

 primrose band uniformly broad on the primaries and including the discal ocellus, and that of 

 secondaries always wider than in any examples of H. maia seen by me. This band, too, is of 

 rather different shape, and invariably reaches the posterior margin farther from the anal angle 

 than is the case with H. maia. The wings, too, are much more transparent than those of the 

 common form, and in some cases appear to be almost denuded of scales. I have during the 

 past summer examined upward of 300 specimens of H. maia, many of which were raised from 

 the egg, but though varying considerably among themselves, in the width and density of the 

 band, I have seen none that I could not very readily separate from the form now under notice. 

 My specimens (3 & , 2 $ ) are all from Norway, Me., and from near Bangor, Me.] 



[The records of the United States Department of Agriculture indicate its occurrence at 

 Aweme, Manitoba, where three males were collected by Mr. Norman Criddle. A female in the 

 National Museum is labeled Colorado; it is from the collection of H. S. Burnett. Dr. W. T. M. 

 Forbes states that lucina occurs at Worcester, Mass., and West Swanzey and Fitzwilliam, N. H. 

 He has never seen H. maia as far north as these New Hampshire localities, nor at Worcester, 

 though it occurs in eastern Massachusetts.] 



[Dr. Packard examined the types and made the following notes :] 



Five examples, all uniform. A good local variety. Expanse of fore wings s 50, 9 55-62 

 mm. ; white band very wide, as in nevadensis, but dark part of wing paler and more hyaline than 

 in nevadensis, so that the difference in hue between the middle and outer edge of wing is much 

 less marked than in nevadensis. It is smaller than any of the other specimens of maia, nevadensis, 

 or calif ornica. 



1 [There is considerable confusion, perhaps the result of local variation, as to the true larva of Hemileuca maia. The type locality is New York, 

 and the northern larva, as it occurs in the collection of the United States National Museum, and as described by Reiff, is almost wholly black. 

 The dorsum is dusted irregularly with pale yellow dots, but they have no decided tendency to gather and fuse into a pale stigmatal band. The 

 head is deep red-brown, and the dorsal tubercles show only a little red at the base, the whole effect, whether from front or side view, being a black 

 larva. The food is oak. In the Southern States, as figured by Abbot on Plate 50 of the Lepidopterous Insects of Georgia, it is much paler, but strongly 

 variable. One of his figures represents a dominantly yellow larva, with a black subdorsal stripe, the other has a dark ground color, but the yellow 

 dusting is evidently heavy on the dorsum, and on the incisures and in the broad stigmatal band occupies most of the surface. The subdorsal spines 

 are reddish in both forms, as well as the head and the feet in the figure that shows them. The food is oak as before. The lighter of these two larvse 

 must have been closely similar to that of H. nevadensis, showing a likeness to the Colorado form, that is paralleled by the presence in both localities 

 of the red female of Automeris io. The darker form is represented in the National Museum, and except for its larger size is almost exactly like 

 H. lucina. The larva of lucina is of the black form, but is distinguished from the most northern specimens of that form by the fact that the yellow 

 dotting is much stronger on the sides, forming more or less distinct stigmatal bands. Similar larvse of maia are to be expected, but they should 

 occur much farther south than the limit of lucina, as the typical black form ranges south to Washington, D. C. In the West this hiatus is likely 

 not to exist, but here the adults are strikingly different, as lucina is unchanged in Colorado, while the nevadensis form of maia already appears in 

 Nebraska. However the species may be found to intergrade here. Caterpillars should be collected and moths bred from them in the intermediate 

 district, wherever lucina and maia are likely to occur together, as in southern Canada, and also where the northern and southern larvge of maia 

 meet, probably in Virginia or the Carolinas, and west to Colorado. Wm. T. M. Forbes.!
