and fifteen to sixteen internal spines, which increase regularly in 

 size and length distad.^" 



In life the specimen was probably a very delicate pale green. 

 The body and limbs have now faded to yellowish, except for three 

 small and regularly placed dots on the external face of each cephalic 

 femur, which are very rich green. The tegmina are very pale 

 lumiere green. Mesad across the humeral field is a narrow irregular 

 transverse band, formed by a faint tracery along the veinlets of 

 this area of vinaceous ; there is also a minute fleck of the same meso- 

 proximad in the humeral field. 



Though Haan's figure shows fewer spines and a much more simple 

 tegminal venation, we believe that these differences are wholly 

 due to a certain amount of inaccuracy on the part of the artist.

The very broad oval, pale green tegmina give this little insect 

 a distinctive appearance. The minute black dots on the costal 

 margin of the tegmina are an interesting feature. 



^" We would here note that the spine formulae of the cephalic femora and 

 tibiae is most important in the Mantidse and not always easy to record accur- 

 ately. For the femora we find on the ventro-external margin a few, usually 

 long, spines; on the ventro-internal margin more numerous spines, usually alter- 

 nating in length proximad, and in addition to these should be noted separately 

 the usually minute genicular spines, when present, and the very important 

 discoidal spines, which proximad run in an oblique line across the ventral sur- 

 face of the femur. Three or four of these occur and it is particularly important 

 not to confuse one or two of these nearest the margin with the marginal spines 

 proper. In the tibiae the formulae are more simple. All of the external spines 

 must be counted, but in counting the ventro-internal spines great care must 

 be taken not to include the apical claw, which is much larger and longer than 

 any spine and projects from the dorso-distal portion of the tibia, but might 

 easily be mistaken for the terminal spine of the ventro-internal series.
