14 a Canadian Arctic Expedition, 1913-1 S 
It is possible that this form is simply a variety of one of the numerous 
described species of Entomohrya, though it does not agree accurately with any 
published description that I have seen, or with any of the numerous European 
species in my collection. 
Several specimens under driftwood on tundra, Demarcation point, Alaska, 
May 16, 1914. F. Johansen.

Lepidocyrtus elegantidus Meinert, 1896. 
Dark blue or violet with iridescent scales. Denuded of scales, dull blue or 
violet. Legs yellow beyond the coxae; dentes or entire furcula yellow; first 
and second antennal segments yellow with purple apices; third and fourth 
antennal segments purple; dorsum of head, and sometimes the mesonotum, 
yellow; fifth and sixth abdominal segments and the anterior region of the fourth 
often yellow. Narrow yellow intersegmental bands are often present. The 
unpigmented regions may be white instead of yellow. Body stout. Mesonotum 
arched, concealing the pronotum and projecting moderately over the head. 
Eyes (fig. 64) 8 + 8, on black patches; the two inner proximal eyes of each 
group smaller than the others. Antennae one-fourth to one-half longer than 
the head. Antennal base black. Second and third antennal segments subequal 
in length; fourth segment one-half to two-thirds longer than the third. Unguis 
(fig. 65) with a pair of large lateral teeth, and with two pairs of inner teeth, the 
proximal pair being at the middle of the inner margin. Unguiculus narrow, 
sublanceolate, pointed, untoothed, extending three-fifths as far as the unguis 
on the third pair, and about half as far on the first and second pairs of feet. 
One clavate tenent hair. Fourth abdominal segment three to four times as 
long as the third. Dentes a little longer than the manubrium. Mucro (fig. 66) 
about as long as hind unguiculus, with long apical tooth and well developed 
l)asal spine. Anterior region of head with short stiff fringed clavate setae. 
Anterior border of mesonotum with a dense cluster of stiff clavate setse. Anten- 
nae, legs and posterior region of abdomen with dense fringed setae. Dentes 
with two dorsal rows of subclavate fringed setae. Manubrium and dentes
