band of chitin along their mesal sides. Second lobes distinct, duplex ; 

 mesal part expanded towards the apex and further projecting slightly 

 farther caudad than the lateral part which is wider at the base than towards 

 the apex. The third lobes are distinctly present on one side ; duplex, mesal 

 half large and conspicuous, lateral half shorter distal margin of both parts 

 oblique. A prominent gland-pore projection laterad of the median lobes 

 and a still more prominent one laterad of the second lobes and two pairs 

 on the pygidial margin cephalad of the third lobes. 



Plates 1, 1, 1, 1, 5-Q. A dorsal seta laterad of the median lobes, one 

 between the parts of the second and third lobes and one laterad of each 

 pair of pore-projections. 



Dorsal pores few, large, in three rows on each side of the pygidium, the 

 inner row consisting of three and situated just laterad of the circumgenital 

 pores. 



Circumgenital pore 11 (24 and 25) (18 and 19) ; the median in a 

 compact group, the cephalo-laterals in three or four longitudinal rows, the 

 caudo-laterals in two or three rows. 



Anus at level of interval between cephalo-and caudo-lateral groups of 

 pores. 



Antenna consists of a rounded tubercle bearing a single seta ; antennfB 

 situated as in A fagrecu, Gr. A group of anterior parastigmatic pores 

 apparently present. 



Underneath leaf-sheaths of Penicum uncinatum, Peradeniya, July 1914. 



This insect resembles somewhat Afcujrece, Gr., but differs in the character 

 of the median lobes, in the presence of a third lobe and in the number of 

 circumgenital pores ; (of A fagvece, Gr.), Green says, " the lower groups 

 in every case containing the greater number,"
