PSYCHE. 



[August 1S93. 



cremaster ; abdomen punctured, cases coarsely 

 creased : color uniform dark brown, nearly 

 black. Length 17 mm. ; width 6 mm. 



Food-plants. Poplar (Populus tremnloides 

 and P. balsa mi fe ra). Larvae from Yosemite, 

 Cal. 



J 1 moth. Allied to Gluphisia lintneri 

 Groteand G. avimacula Hudson. Antennae 

 lengthily bi-pectinated, the pectinations 

 black, with dense, pale ciliae; shaft with 

 whitish hairs. Thorax and abdomen densely 

 clothed with dark gray hairs, black and 

 white mixed, much darkest on thorax, the 

 posterior edge of the collar defined by a paler 

 line. Wings dark gray, nearly white scales 

 intermixed with black scales and hairs, the 

 white predominating in the median space. 

 At the base of fore wings, on median vein, is 

 a small ocherous dot, contiguous to, and 

 forming part of a basal ocherous shading, 

 enclosed in the space between median and 

 internal veins, and bordered outwardly by an 

 obscure, brownish-black, transverse line. 

 Sub-basal space gray, clothed with black and 

 white scales becoming lighter just before the 

 t.a. line. Transverse anterior line distinct, 

 velvety black, outwardly produced on sub- 

 costal, median and internal veins and in- 

 wardly arcuate across the cell and submedian 

 interspace, most strongly defined at the 

 internal margin. Median space broad, pale 

 gray, with a central blackish shade-line in 

 which is an obscure ocherous crescent at end 

 of cell. Space below median vein next to 

 t.a. line also shaded with ocherous, extending 

 to the t.p. line along internal margin. The 

 veins are slightly lined with black. Trans- 

 verse posterior line whitish, dentate, pre- 

 ceded and followed by a black shade which 

 is emphasized by the black markings on all 

 the veins before the line, and fills in the sub- 

 terminal space outside of it. Subterminal 

 line outwardly arcuate to vein 4, thence again 

 strongly arcuate to the interspace between 

 veins 2 and 3 and thence straight to internal 

 angle. It is shaded with ocherous yellow 

 and bordered outwardly with dark brown; 



but is narrowly broken on each vein by the 

 gray ground color. Terminal space even, 

 dark gray; fringes spotted with white and 

 blackish brown. Hind wings thinly scaled, 

 dark gray, paler at base, with two transverse 

 pale lines denned by black scales and, on the 

 internal angle, by three distinct black spots, 

 the lower one of which is on the fringe. The 

 outer line is faint, but is tinged with ocher- 

 ous at the anal angle. Fringe as on fore 

 wings. Beneath, blackish gray; a common 

 extra mesial pale band, bordered inwardly 

 with black. Hind wings whitish centrally. 

 Expanse of wings, 41 mm. 



Mr. Neumoegen has recently proposed the 

 name Melia* (which, however, is preoccu- 

 pied) for the linterni group of Gluphisia, 

 describing as the type M. daubyi. This is 

 the form of Gluphisia severa found in the 

 Northwest, and I do not think it specifically 

 distinct from that which occurs in the Sierra 

 Nevada. I have taken it at Portland, Oregon, 

 and have seen two examples in the collection 

 of Mr. R. H. Stretch, presumably captured 

 in Seattle, Wash. 



A COCKS-COMB GALL ON RHUS 

 MICROPHYLLA. 



BY C. H. TYLER TOWNSEND, 

 KINGSTON, JAMAICA. 



On June 16. 1S92, I found a gall of very 

 striking appearance, from its deep scarlet 

 color, on Rhus microphyiia, near Mud 

 Spring, which is on the road between Las 

 Palomos and Cuchilla Negra, in Sierra 

 county, N. Mex. The gall is of peculiar 

 shape and resembles a cluster of many 

 thickened leaflets massed together. At a 

 casual glance, it might be mistaken for the 

 fruit of the Rhus, which is in clusters and 

 orange-colored but very different in form. 

 The same gall was found next day, June 17, 

 in the upper portion of the small canon 

 known as the Canada Alamosa.
