PSYCHE.
CERURA ALBICOMA Strecker.
1884 -- Strk., Proc. acad. nat. sci. Phil., 284.
Habitat -- Colorado.
CERURA PARADOXA Behr.
188jÌÔBehr Bull. Cal. acad. sci., i, 64. Head, thorax and legs clothed with dense white hairs, slightly tinged with cinereous on the collar, and banded on the thorax cen- trally with black and orange scales ; abdomen cinereous, banded with white on the poste- rior edges of the segments. Fore wings
silvery white, the transverse bands usually absent, but not diffused as in C~YUYCZ men'- dionalis. When present they are faint,
smoky gray, the inner one excavate on the inner side, nearly straight on the outer and slightly incised on the median and internal veins. (The outer is absent on all the speci- mens before me.) A black dot at base on
median vein ; just beyond it, another on the subcostal; further out, five more in a curved line, the first extending from costa to costal vein, second on the subcostal vein, third on the median, fourth on internal and fifth on the internal margin. The transverse band is represented by scattered, small gray scales; its margin defined in black on the costa and median vein, and strongly marked with
orange scales on the costa, median and inter- nal veins and internal margin. Beyond the band, are five black dots, on the costa, sub- costal, median and internal veins respectively, and on the internal margin, the third just at the origin of vein 2. Median space white with a smoky gray transverse line, inwardly produced on the submedian fold. In some
specimens this is very faint, but not more so than the other markings. Just beyond it, are two rows of venular dots, representing the outer band and separated by a space of from 4 to I mm. The inner row is black, the outer orange, and in one specimen they are the only distinct markings. Terminal space clear white, except a very few inconspicuous small gray scales near costal margin. Ter- minal intervemular dots distinct, black, but variable in size from small to large.
Hind wings non-lustrous white, with the
blackish terminal dots.
Below white, an extra-mesial gray shade
line on fore wings and discal spots on both pair. Terminal dots as above.
Expanse, 37-42 mm.
A decidedly variable species, especially in the distinctness of maculation.
Var. PLACIDA, n. var.
This is the form in which the smoky gray transverse bands are evident at first glance, and the characteristic aspect of the species is much modified thereby. The form is rare, occurring only in two or three females out ot the large number of specimens in Dr. Behr's collection. It is a partial reversion to the usual type of marking in the genus Cerura. Habitat- Nevada Co., California.
CERURA MERIDIONALIS, n. sf.
Head, collar, and patagia white, thorax
centrally mixed with blackish and a few
orange scales ; abdomen apparently pale gray, banded with whitish, but in pool- condition in my specimens. Fore wings silvery white, the usual bands and marks nearly lost, being diffused and scattered into numerous black scales, which cover nearly the whole surface. Basal space white, except for a few dots, composed of three or four clustered scales, one at base and, further out, three more, on costal, median and internal veins respective- ly, the one on the median vein much further out than the others. The transverse band con- sists of black scattered in-orations on the white ground, with a few orange scales about the median and internal veins. Its shape can be made out, being deeply excavate both without and within, but not broken. It is about 5 mm. wide OH internal margin, a
little narrower on costa and only a little over I mm. wide in its narrowest part below med- ian vein. Median space white, with sparse- ly, and irregularly distributed black irrora- tions. The outer band is represented by
scattered black in-orations, which extend to the outer margin, but become more dense
near the inner border of the band, which is quite sharply defined in one specimen, being



================================================================================

lined, nearly continuously, with orange
scales. It starts on the costa, about 4mm. from apex, runs slightly obliquely inwards to vein 5, then curves sharply outward and
turns, running parallel to external margin to its junction with the internal margin, where it becomes obscure. It is outwardly produced on veins 3 and 4. In the other
specimen, this line lacks most of the orange scales, and is very obscure, its course being hardly discernible. Terminal intervenular spots very slight, consisting of four or five very small black scales, not contiguous. Hind wings white, without silvery luster, the intervenular spots larger than on fore wings, smoky black. Below, the wings are white ; terminal dots repeated, enlarged. Expanse 46 mm. Two 9 9, El Paso,
Texas.

Rivers of the University of California.
I have drawn up the following table to
separate the species of Cerura : -
5 I.
Primaries crossed by about eight angularly undulate black lines. Secondaries black - mzdtiscri-pta Riley. Secondaries white.
Lines continuous - scitiscri$ta Walker.
Lines broken - var. candida Lintner.
2. Primaries crossed at basal third by abroad gray band, which may be broken or diffuse or even entirely obsolete.
Primaries dark cinereous--cineyea Walker. Primaries pale cinereous.
A row of dots in median space -var. cinereoides Dyar. Three dentate lines in median space.
Band with defined edges and a few orange scales -- occidentalis Lintner. Band of uniform tint, and without orange scales - modesta Hudson. Primaries white.
Transverse band indistinct, though perhaps broken. Six black spots in an ellipse on disk-borealis Boisduval. Indistinct dentate lines on disk.
Band broad -- scoloj4endrina Boisduval.
Band narrow or broken - ulbicoma. Strecker. Transverse band faint or obsolete, rarely distinct. Black markings much reduced, often largely absent, but not diffuse. Transverse band faint or absent-Yaradoxa Behr. Transverse band distinct-- var. 'placida Dyar. Black markings very diffuse, irrorate, size large - meridionalis Dyar.

Prof. C. H. Tyler Townsend of the New
gists will be pleased to hear that the mathe- Mexico College of Agriculture at Las Cruces, matical physical faculty of Heidelberg has started on a field trip by wagon from University has conferred the degree of there to the Grand Canon of the Colorado, Doctor philosophiae naturalis (honoris via Flagstaff. Prof. .Wooton, of the same causa) upon Baron Charles Robert von College, and two students accompany him, Osten Sacken. and they expect to be away two months.
