Papaipema erubescens, n. sp. 



Fonn congeneric, front smooth, pattern typical. Head and thoracic 

 vestiture yellowish or fawn, mixed with rosy-brown, collar tipped above in 

 lighter shade. Antenna ciliate, with tuft of white scales at base. 

 Primaries rather narrow, apex acute ; basal, medial and terminal areas 

 yellow, powdered with purple-brown ; the ante- and postmedial areas dull 

 purple, but contrasts are not strong, due to the more or less dense 

 powderings. Postmedial line most prominent, indistinctly double, the 

 inner line brown the outer dark purple. It projects very slantingly out- 

 ward from the costa, making quick turn at vein six, thence nearly straight 

 to inner margin, which it meets at a much less oblique angle. Stigmata 

 usually white, sometimes entirely yellow; size normal, agreeing with typical 

 harrisii in definition. The central mark of reniform and the outer middle 

 portion always yellow, the orbicular shows a central brown dot. Second- 

 aries pale yellowish, more or less roseate, always with smoky medial band 

 and the veins showing a little darker. The under side is more glistening 

 and densely powdered with smoky-brown. The genitalia conform to the 

 normal type for the genus in the harpes, but the curved hook arising on 

 the side is without the usual teeth on the posterior edge. Expanse, 36-40 

 mm. Habitat, San Francisco, Cal., and probably over the range of its 

 food-plant in that State. 



Eleven males are for comparison, and other specimens have been 

 seen. A male type is in the author's collection, and cotypes are with 

 Messrs. Mceser and Williams. 



While somewhat variable, erubesceris will be easily recognized super- 

 ficially and by the wing outline. The smooth hook or clasper of the 

 genitalia is not duplicated exactly in any other species, except the Cali- 

 fornian angelica^ whereas the toothed form of this process holds with over 

 thirty species, and is a feature emphasized by Prof. Smith as an exception 

 for the Noctuids, at the erection of Papaipema. Mature larva similar 

 to harrisii series in size and appearance. Head normal. Colour pale 

 flesh-tint, whiter on last five joints, lines lost. Tubercles prominenr, 

 roughed; Hb, HI and IV large and close together on thoracic joints; 

 IV the largest on the abdominal ones, with no trace of IVa on joint ten. 

 Shield smooth, glistening-brown ; spiracles black. Pupa very cylindrical, 

 though not apparently cramped in the barrow ; similar to i/npecuniosa, 

 though the latter is always wedged tightly in the boring. There is no 

 unusual feature, no prominence on the front, and there miy or may not
