ably broader than long. Valves of anal operculum acuminate. Anal cleft 

 approximately one-eleventh of the length of the insect. Anal ring with six 

 stout setae. No stigmatic clefts or spines. A crowded sub-marginal series of 

 circular multilocular pores (figs. 3-a and 3-d) extends the full length of the 

 body, on each side, interrupted onlj' at the anterior and posterior extremities. 

 A large group of similar pores surrounds the genital orifice, on the venter. 

 There is a loose series of short ciu'ved hairs, placed just within the margin, 

 immediately outside the lateral series of pores, these hairs becoming marginal 

 ar the tAvo extremities of the insect. A pair of longish hairs is situated between 

 the bases of the antennae, with a pair of smaller hairs slightly posterior to 

 them. Immediately anterior to the base of the anal cleft are two pairs of 

 longish hairs, on the venter, and a group of four similar hairs on the preceding 

 segment. Other minute haii-s are sparsely scattered over the surface of the 

 venter which is also closelj' studded with minute tubular pores. Length 3.50 

 to 4.75 mm. Greatest breadth 1.25 to 2.0 mm. 



Other stages not observed, but ovisacs — probably of this species — were 

 found on November 10th. They ai'e white, elongate, stout, roughly cylindrical, 

 and are packed with rosy pink eggs. They are very easily detached from their 

 siipport, and most of them were fovind lying loose at the base of the grass 

 stems. They are considerably larger and sto\iter than ovisacs of Liizidaspis 

 Inzulae found at the same time. The eggs are of a more pronounced red and 

 are more evenly dvxsted with mealy powder.
