HEMILEUCA Walker. 



[Bemileuea Walker, Cat. Lep. Het. Brit. Museum, VI (1855), p. 1317.] 



Imago. — <? and ? . Head moderately broad, more or less hairy and bushy. Eyes moder- 

 ately large. Antennae well pectinated to the end, the pectinations curved in the manner charac- 

 teristic of Coloradia and Pseudohazis; antennal joints short so that the pectinations are closely 

 crowded; in 9 the pectinations are distinct, about twice as long as the joints, even on each side, 

 and thick at the base, ending acutely; those of the outside are a little longer than those on the 

 inside. 1 Palpi short, feeble, depressed, scarcely visible, as their scales are with difficulty dis- 

 tinguished from those of the lateral region of the front. Thorax moderately stout and quite 

 hairy. Fore wings with the costa straight, very slightly concave near the middle; the apical 

 region slightly turned up ; outer edge short, much shorter than the inner. Hind wings with the 

 costa straight, also slightly concave along the middle; apex moderately pointed; outer edge 

 quite evenly rounded; inner edge straight or slightly convex. 



Venation: [PI. LIL] 



Abdomen of s broad and flattened, with a spreading, often scarlet, tuft at the tip. 



Markings: Ground colors usually (H. maia and juno) dark or black-brown, with a broad 

 median white band crossing wings of both pairs. Discal spot a pale or white crescent, usually 

 well marked, and one either nearly as large on the hind wings (H. maia) or obsolete (H. juno). 



HEMLLEUCA ELECTRA Wright. 

 Plate LXII, figs. 10, 11; CXII, figs. k-p. 

 \Hemiltuca electra Wright, Papilio, IV (1884), p. 19; Watson, Entom. News, XXIII (1912), PI. VII. fig. 1, 9.] 



o* , 9 • Near H. yavapai; fore wing same shape, apex, etc. ; hind wing shorter, more 

 rounded; ocellus same, white on a black field, beside broad extradiscal [band] nearly reaching 

 outer edge; three white patches, two in middle of wing and one along basal half of discal area. 

 Hind wing in & dark, suffused with salmon flesh color; in 9 whole wing salmon except a broad 

 marginal black band; ocellus large, entirely black. Beneath, wings mostly salmon, in 9 still 

 clearer. San Diego [California]. 



[Ab. rickseckeri Watson, Entom. News, XXIII (1912), p. 97, PI. VII, fig. la, 9. Fore 

 wing above wholly jet black except for the discal spot, a faint diffused white streak widening 

 from base to halfway up the cell and a faint diffused whitish spot on hind margin divided by the 

 submedian nervure. The nervures submarginally penciled with the faintest possible traces 

 of white. Hind wing above with the costal margin heavily outlined with black extending 

 to the large oblong black discal spot, which has a distinct transparent line within. Outer 

 margin heavily outlined with black which runs up the nervures as far as the discal spot. Both 

 wings below have the costa and outer margins broadly suffused with black. No apical white 

 suffusion. Body less heavily banded with white below. San Diego, Cal. This is a highly 

 melanic form, and the name must be applied to very dark examples of H. electra, few of which 

 will probably agree in every detail with the description.] 



[The species is quite variable. In Watson's figure of the female the submarginal light 

 band of anterior wings is very strongly developed, broad, quinquedentate on outer side, and 

 the subbasal light triangle is large and well developed. In a female (also from San Diego) 

 in the United States National Museum these markings are faintly indicated, the submarginal 

 pale band being represented only by a series of elongated marks, traces of which are also 

 present in the type of ab. rickseckeri.]
