no. i. BOMBYCINE MOTHS OF NORTH AMERICA— PACKARD. 139 



Body dull brown-black, with a slight reddish tinge, with no stripes or spots, but the skin is 

 somewhat rough; the sutures between the segments are paler, being dark flesh-colored. The 

 spine like tubercles are long and all over the body, are uniformly dull brown-black, and giving 

 origin to golden-yellow hairs wliich are about twice as long as the spines from which they 

 arise. Suranal plate and anal legs of the same color as the body. 



The dorsal thoracic spines (on each of the three segments) are longer and larger than the 

 others behind and deeply forked, those on the prothoracic segment being 3-forked, as also 

 subdorsal ones, while those on the second and third thoracic segments are bifurcate. They 

 are about as long as the body is thick. Abdominal dorsal spines considerably shorter than the 

 thoracic one, simple at tip, with a tine lower down. On the eighth and ninth abdominal seg- 

 ments is a bifurcate median spine. The spines are rough, tuberculated, but shining black. 

 The thoracic legs are black, the middle abdominal ones dark flesh-colored, the under side of the 

 body dull flesh color. 



Stage II: After the first molt, June 9-10. Length, 10 mm. Head and body still black, 

 but while the subdorsal and lateral spines are still black, as also the two dorsal prothoracic 

 ones, the spinules around the base of the second thoracic spines are bright ochreous yellow as 

 are the whole of the dorsal, third thoracic ones, and all the abdominal ones, thus the back of the 

 larva behind the 'prothoracic segment is gamboge-yellow, where before it was nearly all black. The 

 skin of the body instead of being black is dark livid purple, including all the abdominal legs, 

 the thoracic legs being shining black. Also the armature has now changed, the dorsal third 

 thoracic and abdominal spines being more verticillate and bushy, the central two of the spinules 

 being black, the others yellow; they are not much more than half as high as the first and second 

 thoracic dorsal spinules. 



PSETJDOHAZIS HERA var. MARCATA Neumoegen. 

 [Pseudohazis hera var. marcata Neumoegen, Canad. Entom., XXXIII (1891), p. 146.] 



[Neumoegen's original description is as follows: 



Antennae dark brown. Head, prothorax, patagia, and legs light yellow. Thorax the same, with blackish ground. 

 Abdomen white, with black segmentary bands; lower border of each segment as well as anal tuft of bright yellow. 

 Primaries pure white. Costa, apices and fringes black. The intersection of each nervure at exterior margin accen- 

 tuated by black dashes, pointing inwardly. A prominent black mesian line and a large black discal spot, faintly 

 showing the white kernel. A basal dash encircled by a black outwardly curved line from inner margin to costa, 

 terminating in an irregular costal spot. 



Secondaries pure white with black marginal line and fringes interspersed with black, a large black discal spot and 

 mesian line; the latter curved outwardly near median nervure so acutely as to give the line nearly a triangular shape. 

 In some specimens the ends of discal spot are confluent with mesian line. Below, primaries and secondaries pure 

 white, with markings as above. Abdomen with black lateral dots and black segmentary bands. Secondaries with 

 black costa and termini of nervures slightly tipped with black; a black irregular line encircling basal space. 



Types. Coll., B. Neumoegen. 



Habitat, Klamath County, Oreg. 



This handsome variation is so decidedly marked as to be distinguishable at first glance from th • typical hera by 

 the entire absence of black terminal dashes of nervures of secondaries and the lack of black basal tinges. 



I have about 50 specimens before me all uniform in appearance.] 



MEROLEUCA Packard. 



[Mesoleuca Packard, Journ. N. Y. Ent. Soc, XI (1903), p. 247, not of Hubner.] 

 Eemileuca Walker, in part, Cat. Lep. Het. Br. Mus., VI (1855), p. 1319. 

 [Meroleuca Packard, Journ. N. Y. Ent. Soc, XII (1904), p. 250.] 



Male closely allied to Ilemileuca, but differing in the larger, longer palpi, the shorter wings, 

 and in the venation. 



Head as in Hemileuca, hairy and shaggy in front, of about the same width between the 

 eyes, which are of the same size as in Ilemileuca. The antennae differ in the joints being longer, 

 so the pectinations are farther apart, but in their length and hairiness the two genera are 

 similar. Palpi much longer and more distinct than in Ilemileuca, projecting well beyond the 

 front, but the hairs on them are bushy or shaggy and irregular. The thorax and abdomen are 

 as in Ilemileuca.
