II, which is not true for L. pusillus. The pigment in L. purpureus 
also presents a decidedly mottled appearance, especially in 
mounted specimens. 
L. purpureus may be svnonomous with L. metallicus L. 
cvaneus and L. iricolor, but according to Packard’s description 
L. metallicus differs in the following respects. The spring is 
short and thick, the manubrium unusually broad, and the 
mucrones extra large. It also seems to differ in its blackish- 
bronze color. As before stated, L. iricolor is not sufficiently 
characterized to identify with any of these species. 
L. purpureus is very abundant about Columbus, and may be 
found in abundance under loose bark of fallen trees, as well as 
in the other usual localities for Lepidocyrtus. It seems to live 
in the confinement of artificial cells about as well as in its natural 
surroundings. In coloration it is one of our most beautiful 
species. 
Life History of Lepidocyrtus Purpureus. PI. XXIX. The 
young of the above species, closely resemble the adults. In 
color they are a lighter blue, quite silvery to the naked eye, not 
showing the purple reflections so marked in the adults. The 
head seems quite out of proportion to the rather slender body. 
The larvae of L. purpureus are remarkedly agile, thus very hard 
to study alive for structural details. Mounted specimens show 
every detail of character in the claws, spring and antennae 
found in the adult, even to a constancy in the arrangement of 
the hairs over the body. The black eye spots are very noticeable 
at the bases of the antennae, and plainly visible from above, in 
contrast to L. sanguineus. From the colonies observed it seems 
that eighteen to twenty eggs may be produced at one time by 
this species. Larval forms measure from 0.20 mm. to 0.25 mm. 
in length. 
Lepidocyrtus Sanguineus, n. sp. PI. XXX. 
(Description taken from living and mounted specimens.) 
Color: white, with iridescent scales, sometimes with a bluish cast. 
Antennae: segment III shorter than II; IV nearly or quite twice as long 
as III, or equalling II plus III; length of segments slightly variable; 
densely covered with short hairs. Eyes: red, unusually small with single 
ocellus, appearing at side of head near bases of antennae as mere specks. 
Plainly visible on venti ' surface. Fringe of clubbed hairs on mesono- 
tum clubbed; various long, barbed hairs scattered over the body, legs and 
head; four long, barbed hairs are found regularly on both abdominal seg¬ 
ments II and IV. Scales rectangular, largest on the manubrium. Meso- 
notum in dorsal view fully four times as long as metanotum. Abdominal 
segment IV four times as long as III. Legs: tarsi bear two claws, the 
larger with two teeth; the smaller claw nearly straight with a slight curve 
at its tip. A long hair is present on the tibia of each foot, but is not a 
true tenent hair in function. Spring: manubrium densely covered with 
hairs and large, broad scales; dentes somewhat longer than manubrium,
