 sides of abdomen deep black-brown ; ventral segments throughout blotched 

 with black-brown in three irregular and wide longitudinal lines ; posterior 

 tibige, tarsi, and spines, with the ovipositor, piceous ; tibicB quadrangular,

 in three rows ; and posterior pair with seventeen spines in four rows (three 

 of them alternately bearing five spines each), the outer row being very long 

 and acute, increasing in length downwards, the lowest spine at the base of 

 tibia 4 lines long ; femora, anterior, and middle pairs smooth and spineless ; 

 posterior pair each having two longitudinal rows of spines, eight in a row, on 

 the inner side, regularly marked on the outside with transverse wavy light 

 lines ; coxa each armed with a single spine, those of anterior pair long and 

 sharp, of posterior short and very obtuse ; four joints of tarsi cushioned, 

 each with a prominent broad transverse pad, besides pulvilli ; last joint of 

 tarsi the longest; terminal spines, or hooks, of tarsi large, long, and falcate; 

 ovipositor curved upwards, blades slightly concave, thin, and elliptical at 

 apex ; four long stout acute spines above, two on each side of anus ; pos-

Hab. — In a small low wood behind Paihia, Bay of Islands ; 1839. 



This species is bigger every way than H. hetaracantha, with which 

 species, however, it has close afSnity. It is also much more spiny, and 

 differs greatly in colour, etc. It is a very fine and handsome insect. 



It has a little semi-public history, which may be here very briefly given. 

 It has been seen and admired by Dr. Dieffenbach, Dr. Sir Joseph Hooker 

 (and the other officers of that Antarctic expedition), Dr. Sinclair, Lady 

 Frankhn, the several early French and American naturalists who had 

 visited New Zealand, etc., etc. 



It was long supposed (from the pubHcation of Dr. Dieffenbach's work on 

 New Zealand in 1843) to be identical with Deinacrida heteracantha of that 

 work (vol. ii., p. 180), and, if so, should have been the type (being the old 

 original specimen) ; but a close examination of late years served to show 

 their respective and great differences. This specimen remained packed up 

 in the box in which it was brought away from the Bay of Islands, from 

 1848 to 1864 ! It was, however, exhibited at the New Zealand Exhibition* 

 ' at Dunedin in 1865, as Deinacrida gigantea. Col. ; and although it has been
