Pellenes borealis, Banks. 1895. 
Habrocestum cristatum, Pkm. Attidae of N. A., 1883. (Plate XII, 
figures 4 to 4C.) 
The female is 5—6 mm. long, the male 45—5 mm. The 
female is hight gray and brown like the sand, while the male is 
deep black with white markings. The legs of the male have no 
peculiar modifications either of the first or third pairs. The mark- 
ings of the female are very indistinct; the cephalothorax is varied 
with white, sometimes suggesting two white lines from the lateral 
eyes backward. The abdomen has a white line across the front and 
two pairs of short lines at the sides. Toward the end there are 
two middle spots, sometimes connected, and the usual two small 
white spots just in front of the spinnerets. The male has the ce- 
phalothorax black with long black hairs on the front of the head. 
The abdomen is black and has the same markings as the female, 
but much whiter and more distinct. The legs are pale, but the 
color is darkened by black hairs. The face below the eyes is white 
in the female, and in the adult male is thinly covered with small 
white scales, but in the young male before the last moult, this part 
is bright red, so that it may be mistaken for the young of P. ca- 
catus, which lives farther south. See Psyche, Journal of Cambridge 
Ent. Club, Vol. II, p. 32, April, 1904. 
The epigynum has a large oval anterior opening extending back- 
ward at the sides almost as far as the posterior opening. The 
palpal organ is oval and has a stout supporter of the tube extend- 
ing along the inner side and but little narrowed toward the end. 
This spider is very common along sea beaches in the dry grass 
and rubbish thrown up by the tide. Adults are found most ab- 
undantly about the first of May, but some of them mature in the 
late summer as early as the last of August. The red-faced young 
males are found in the summer and fall, and in spring as late as 
June. 
Chalcoscirtus montanus. 
Icius montanus, Banks. Can. Ent., 1896. 
The cephalothorax is 1.2 mm. long, the abdomen of the male 
about the same length, and that of the female longer. The cephalo- 
thorax is two-thirds as wide as long, a little flattened above and 
with the sides nearly straight and parallel. The posterior eyes are 
half as far from the front eyes as they are from each other and 
the middle eyes are slightly nearer the posterior than the front eyes. 
The color differs in the sexes, the male being much darker than
