210 Transacfiojis. 



Legs. 



Bristly, elongate, especially the posterior pair, the anterior being shortest ; 

 tawny, femora lighter frona the proximal end, the tarsi becoming darker 

 (listaily on account of short closely set bristles ; hind femora flattened late- 

 rally and slightly convex anteriorly, covered with minute bristles also bear- 

 ing upon the under side a double row of large divergent spines, and upon 

 the upper side an irregular row ; hind tibiae straight, with minute bristles, 

 which upon the upper side are arranged regularly in a double row between 

 two rows of large bristles, 4 in the inner and 6 in the outer row, diminishing 

 in length toward the proximal extremity ; also a pair of pre-apical and a 

 pair of short apical bristles ; middle femora straight, rounder and less bristly 

 than the hind femora ; middle tibiae with larger outer spines and a few 

 smaller inner ones, also with a whorl of strong pre-apical bristles ; front 

 femora less bristly than hind femora, posteriorly convex and rounded, 

 anteriorly flat ; front tibiae with a whorl of strong pre-apicai bristles ; 

 tarsi elongate and slender ; pidvilli tawny, well developed, almost oval 

 but for the straight inner margin, not projecting beyond the claws : 

 empodium a slender bristle as long as the pul villi ; claws well developed, 

 curved, black towards the tip, otherwise reddish-brown ; metatarsi long,

Art. XXIII. — On Deinacrida rugosa Buller. 

 By A. Hamilton. 



[Bend before the Wellington Philosophical Society, 1st May, 1912.] 



The type of this species was found at Wanganiii in an underground burrow 

 and was originally described by Sir Walter Buller in the 3rd volume of the 

 " Transactions of the New Zealand Institute," 1871, and also figured. 



Subsequently, in vol. 29 (1896), Sir Walter was able to complete his 

 description from a pair found amongst the stones on the beach at Stephen 

 Island, Cook Strait, and which were presented to the Canterbury Museum 

 by the late W. T. L. TraverS. 



The species is a very well defined one, and of considerable interest. 



The specimens which I exhibit to-night were also found on an island 

 in Cook Strait, by Mr. Grei, of Willis Street, who has kindly presented to 

 the Dominion Museum the pair now shown. They were found amongst the 

 decaying vegetable growth on the sides of the gullies. 



The original male specimen was figured in vol. 3, pi. 5e, figs. 1 and 3. 



Unfortunately, no trace of the original or holotype can be found in the 

 Dominion Museum at the present time, and therefore one of the pair in the 

 Canterbury Museum should probably be regarded as the neotype of the 

 species. I therefore .suggest the male of Buller's heautotypes at Christ- 

 church be the neotype of the species.
