now forty-two years in spirits, its colours are unaltered. It is still in its 

 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. 

 Heniideina speluncce, 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) hght 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 ; tibiae and 

 lower parts of femora banded with black and white rings (resembling porcu- 

 pine quills in miniature) ; tarsi light straw colour, translucent : posterior 

 pair of legs ; femur Ij 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, 35-40 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 : rniddle pair of legs ; femur 



9 lines long, naked ; tibia 10 lines long, with four rows of small spines, 

 five in each row ; tarsus 7 lines long, spineless : anterior pair ; femur lO-J 

 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 ciUated with long flexuose patent 

 cilisB, 1-2 lines long ; head rather small, narrower than pronotum, and scarcely 

 appearing before it ; maxillary palpi long and slender, slightly clavate ; eyes 

 rather large, semi-lunar, at base of antennae and nearly behind them, gibbous 

 edge towards thorax ; antenna thick at base and close together, 8 inches 

 long, articulated, light reddish-brown but darker at articulations, very setace- 

 ous, each bearing a row of short obtuse spines on the outer edge in the mid- 

 dle for nearly one-third of its length, spines irregular in size and position, 

 some being near, one on each articulation, some more distant, with 2-3 vacant 

 articulations between, spines always at anterior end of joint, rings of its 

 horns coarser than in the large species (supra) H. gigantea ; body without 

 appendages, 1^ inch long.
