yellow only a patch at base and resting on the internal margin. 

 The wider fuscous border extends also on costal region, and the yellow 

 is paler." 



Mr. Neumoegen contends that this is but a local form of the 8an 

 Domingo species, and he may be right. I have not material enough 

 to settle the question. 



The larva has been but recently described by Mr. Edwards in 

 " Entomologica Americana" iii, 1888, p. 164.

Head large, prominent, untufted ; eyes large, prominent ; not, or 

 very feebly lashed ; j)alpi long, ascending, appressed to front, the 

 basal joint unusually long, second so clothed as to appear clavate, 

 third joint minute ; antennse fusiform with a short, abrupt, recurved, 

 setose tip ; tongue as long, or longer than the l)ody. Thorax stout, 

 well advanced before base of ])rimaries, with short, stout, erect, post- 

 thoracic tufts. Abdomen cylindn)-conic, pointed at tip, untufted, 

 the segments posteriorly spinulose. Legs moderate in length, stout, 

 somewhat lengthening {)osteriorly ; median tibise with one pair, pos- 

 terior with two pairs of long, unequal spurs. The fore tibiie and 

 tarsi are variably armed ; in celeus there is a series of dorsal spinules 

 on tibia, two long spines outwardly near tip, three distinct, long, 

 stout outer spines to first tarsal joint and a long spine at tip of second 

 and third tarsal joints ; in Carolina the armature is similar, but very 

 much reduced ; the spines of fore tibiie are minute and hardly promi- 

 nent ; those of the tarsi are more slender ; in rustica the arn)ature 

 is still more reduced, that of fore tibiae con.sists only of minute 

 spinules at tij) ; first tarsal joint with a series of small lateral spines 

 and a larger one at tip ; the second and third joint with simply a 

 longer spine at tip ; in cingulata the fore tibiie are entirely unarmed, 

 and the tarsal joints have the faintest reproduction of the armature 

 of Carolina. 



The primaries are usually eleven veined ; rarely a specimen will 

 have twelve veins ; the outer margin roundedly oblique ; in celeus 

 (which has the primaries somewhat broader also than in the other 

 species), somewhat more oblique in Carolina., with a trace of an in- 

 denture on vein two, while in rustica and cingulata the excavation on 

 vein 2 is distinct, and the angle below prominent. Secondaries with 

 the margin somewhat pi'oduced on vein lb ; in celeus less so than in 

 the others. The venation is of the typical form.
