456 Mr. John Scott on certain 



branches of the upi^er furcation and between the upper 

 branch and the apex of the radius (measured on the 

 marginal nerve) equal ; distance between the branches 

 of the lower furcation twice as great as that of the 

 adjoining area measured in a similar manner. Abdomen 

 above pale green, obese ; two basal segments above yel- 

 lowish, or with a reddish tinge ; sides with a somewhat 

 irregular, triangular black patch on each segment ; 

 posterior margin of the segments narrowly black. Length, 

 If line (Paris). 



Hob. Sierra Leone. 



The collection possesses three specimens, one of which 

 is on a small portion of a leaf of some tree or shrub 

 having two somewhat large circular galls on its upper 

 side, which, I presume, were caused by P. lata.
