pleura, and on the outer side of the mesopectus, are rows of three large spines on each' 

 besides numerous tubercles. On the central line of the meso- and metapectus is a well- 

 marked carina, attenuated in front, and on the metapectus are four strong spines on each 

 side, besides smaller ones in the middle. The tegmina have a sliort spine at the base ; 

 the base is black, except along the costa ; the outer half is testaceous. There is a strong 

 ridge over the black portion ; the testaceous portion is partly reticulated with black. 

 On the metapleura is a very strong spine below the middle of the wings, a shorter one 

 more in front, and several strong ones along the lateral ridge. Beyond the wings, which, 

 so far as can be seen, are f usco-hyaline, with reddish nervules, are two strong spines in 

 the middle, on each of the two following segments, besides numerous small ones. The 

 lateral ridges are also thickly spined. The extremity of the abdomen (the last four 

 segments) is much enlarged in the middle. There are four strong spines, gradually 

 diminishing, besides smaller ones on most of the segments of the abdomen ; the last four 

 segments being almost destitute of spines, or even tubercles both above and below. Tlie 

 coxsB, femora, and tibia? are strongly spined on nearly all the carina? and on the fore hinder 

 legs, on the front legs more sparingly. On the hinder ones, numerous small teeth fill up 

 the interspaces between the others, which are often rather wide apart. 



The female is a dark brown insect, spined nearly as in the male, but larger and more 

 bulky. It differs from that of S. Dehaanii, Westw., by its much larger tegmina, the 

 larger and more regular series of spines on the sides of the abdomen, and the much 

 stronger spmes on the legs, &c.

The type of Phasma, Illiger, was fixed by Latreille as Mantis rossia, Fabricius, which 

 was subsequently taken as the type of Bacillus, St.-Farg. & Serv. They took Mantis 

 necyduloides, Linn., as the type of Phasma, and have been followed in this by recent
