the margin markedly constricted. Dorsum with a large keel-like process. Caudal 

 process very short and conical. Stigmatic clefts deep. Antennae of eight seg- 

 ments ; the articulations relatively very broad ; 3rd about equal in length to the 

 7th and 8th together ; a very long hair on the 2nd and 5th, and a slightly shorter 

 one on the 8th ; there are two spines on the 8th and one on the 7th. Legs normal. 

 Stigmatic spines covering a large and somewhat pyriform area, the length of which 

 is nearly equal to twice the length of the antennae ; the spines, with the exception 

 of a small group near the stigmata, are obconical and the space between them with 

 bands of dark granular bodies, which collectively form a polygonal reticulation ; 

 the small proximal group of spines are longer than the others and pointed. No 

 trace of marginal spines. Derm thin and transparent after maceration ; rather 

 thickly set with minute pores and minute scattered spines. Caudal process sur- 

 rounded by a porose zone of brown chitin. Length 3'9-4*6 mm." (Newstead). 



The above description does not refer to the mature female forms which attain, 

 with the waxy test, 14 mm. long, 12 mm. broad and 8 mm. high. The colours 

 remain the same except that the lighter parts become yellowish. 



When mature the denuded female is densely chitinous, brownish black, with the 

 dorsum smooth, shining. In boiling KOH it stains the liquid deep purplish 

 brown. The antennae are sometimes 7- jointed with joint 4 very long, obviously 

 4 -}- 5 of the 8- jointed form.

Genus Inglisia, Mask. 

 Adult female more or less conical, covered above by a glassy shield which is 

 divided into plates and striated with rows of air cells. Legs and antennae well 

 developed. 



239. Inglisia elytropappi, sp. n. 



Test of adult $ small, l"6-2 mm. long, 1'2 mm. wide and high, like a small bivalve 

 shell with its hinge uppermost standing on the stem. It is very like a small zizyphi 

 test but paler in colour, with the upper angles of the two halves smooth instead of 

 tuberculate. The colour is white to pale buff, shiny, often pearly, with the vertical 

 striae conspicuous. 



$, with the test removed, shiny dark brown, of the same general shape as the test, 

 with the apex depressed between two rounded lateral humps. 



Cleared and mounted the body is hyaline. The margin has a close-set row of 

 short conical spines with broad bases and moderately sharp points. The stigmatic 

 clefts are obsolete, but their presence is indicated in the marginal row of spines by 

 the addition of a single, slightly longer spine with a narrower base. 



The antennae are rudimentary, appearing in varied forms with very indistinct 

 segmentation ranging from 4 to 7- jointed. When 7-jointed the segments are 

 generally very short — mere rings. The measurement of such an antenna gave 

 the following in ju :— (1) 17, (2) 6, (3) 17, (4) 6, (5) 10, (6) 6, (7) 6.
