original clear glass bottle with the liquid clear and pure: but the ground- 
glass stopper having become firmly fixed, and not choosing to run the risk 
of injuring the specimen (which, as far as I know, is unique), I have given 
some of its measurements as approximate only,—but they were carefully 
taken and are very nearly quite correct, at all events within a line or two. 
Hemideina spelunce, n. sp. 
Colour: body beneath light ochreous; pronotum, both anterior and pos- 
terior edges broadly banded with black, mesonotum and metanotum also 
having a black band close to posterior margin, but all the thoracic and 
abdominal segments have a narrow white line on all their dorsal posterior 
and side edges; abdomen above brownish, dirty raw umber at the base; 
posterior femora (upper parts only) light reddish-brown, transversely and | 
closely banded with finely waved and regular lines of a darker brown, in | 
three longitudinal and separate rows, the markings all different in each : 
row ; middle and anterior femora (upper part only) ochreous; tibia and 
lower parts of femora banded with black and white rings (resembling ae 
pine quills in miniature) ; tarsi light straw colour, translucent: posterior 
pair of legs ; femur 14 inch long, with one row of seven very small distant 
spines on the inner edge ; tibia 1} inch long, slightly hairy, with two rows 
of fine close spines, 85-40 in a row, on two inner edges, sulcated between 
the rows, at base of tibia two long and villous white spines; tarsus 4-jointed, 
8 lines long, smooth, translucent, finely and thickly pubescent, with a single 
small spine at the base of each joint, joint nearest to the tibia the longest 
(as long as the other three taken together: middle pair of legs; —_ 
9 lines long, naked; tibia 10 lines long, with four rows of small spmes, 
five in each row; tarsus 7 lines long, spineless: anterior pair ; femur 104 
lines long, with a row of six small spines; tibia 11 lines long, with a row of 
four small spines ; tarsus 8 lines long, spineless, slightly villous and trans- 
lucent; two long spine-shaped processes, each 4 lines long, at end of abdomen 
near anus, one on each side, whitish, finely ciliated with long flexnose patent 
cilie, 1-2 lines long; head rather small, narrower than pronotum, and y 
appearing before it; maxillary palpi long and slender, slightly clavate ; 
rather large, semi-lunar, at base of antenne and nearly behind them, ces 
edge towards thorax ; antenne thick at base and close together, 8 inches 
long, articulated, light reddish-brown but darker at articulations, very setae 
ous, each bearing a row of short obtuse spines on the outer edge in the
