CoLENSO. — On new Species of Orthoptera and Coleoptera. 277 



I also searched the Little Barrier Island for tuataras, but in vain. The 

 large quantities of feral pigs living upon that island may easily account for 

 their absence. There are also none on the Hen and the Guano Islands. Most 

 frequently they were found by me on the large western Chicken Island. I 

 believe that they are still more abundant on the smaller islands ; however, 

 although I tried repeatedly to land on them, the heavy surf would not allow 

 me to do so.

OETHOPTEEA. 



Fam. Mantid^. Genus Mantis.

 Pronotum five lines long, anterior end widest, ridged down the middle,

 translucent when viewed between eye and light, side-margins rough finely 

 sub-serrulate, edge straight sloping gradually to mesonotum. Anterior 

 pair of legs : trochanter very slightly serrulate at margins ; femur two 

 rows of spines of irregular lengths, inner row small and closely set, outer 

 four only large and distant, a large purple oval or kidney-shaped spot 

 central within ; tibia two rows of spines, regular, ending in one very long 

 curved one at base ; tarsus long ; costcs of the anterior wings (elytra), one to 

 each, run longitudinally parallel with and near the outer margin, with 

 transverse flexuose nerves branching inwardly and diagonally from it, 

 wholly filled up between them with fine anastomosing veinlets ; elytra 

 semi-transparent ; posterior wings much smaller and very membraneous ; 

 wings extending far beyond base of abdomen ; abdomen thick smooth. 

 Antennm short, 3^ lines long ; eyes large, two small protuberances 

 (? stemmata) between horns and just behind them : total length from 

 head to posterior edge of elytra 1\ inches : length of nympJia IJ inches. 

 Colour (of both states nearly alike), mostly light emerald green ; under- 

 neath, about mouth and thorax, and inside of fore-legs pale lemon ; outside

Hab. — Scinde Island, Napier, on trees [nympha state only), 1878-1879, 

 Mr. J. A. Eearden ; imago state (one specimen), 1880, Mr. J. D. Ormond. 



This species has pretty close affinity with the European species M. 

 religiosa, but it is very much smaller, with shorter horns, and less spiny 

 and narrower fore-legs, etc.
