Piipariuin of the <? very elongate, rounded, convex, and widest immediately 

 behind the larval exuvise, and more or less pointed at the posterior extremity ; 

 white and closely felted. Long,, "50 — "70 mm. 



Hab. : on Howea Fosferiana, in temperate house, at the Eoyal 

 Gardens, Kew, March, 189S. Eeceived from the Curator, Mr. G. 

 Nicholson. 



This species has the singular habit of living in little colonies or 

 family parties, which generally consist of two or three females and 

 several males. The insects were very abundant on the leaves sub- 

 mitted to me. It seems a well-marked species, and hitherto undescribed. 



LlCHTENSIA EPHEDBJE, 11. Sp. 



9 ovisac pure white and very closely felted ; very elongate, transversely and 

 longitudinally convex, or boat-shaped. 



Long., 8 — 10 nun. ; wide, 3 mm. ; greatest height, 2'50 — 3'50 mm. 

 J pupariuin (scale) glossy-white, of the ordinary Lecanoid form. 



Long., 2'25 mm. 



? adult ovate, marginal spines short, blunt, equidistant, and 

 continuous, rarely two examples ai'e placed together, the rest of 

 the epidermis i-emarkably free from spines, hairs, or spinnerets. 

 Spiracles trumpet-shaped. Mentum monomerous. Anal dorsal 

 lobes normal. Anal ring with 8 long hairs. Antennae (fig. 5) of 

 8 joints, of which 3 is long as 4 and 5 together ; foi-mula, 3, 2 

 (4,5,8), (6,7), 1. Legs slender; digitules to tarsi long, stout, 

 are of uniform width throughout, with truncate ends, those of 

 the claw scarcely shorter, but stouter, dilate at apex, and finely 

 but unequally divided and pointed. 



Ova. Crushed examples had stained the ovisacs bright 

 crimson. 



Rah. : on Ephedra nlte, C. A. Meg. {Cretacece), and 

 j'9-'~'- apparently peculiar to this plant. "Gathered in the 



Waddy Gerrawy, Helonau, 15' South of Cairo, February, 1900. 



The specimens were kindly forwarded to me by Admiral R. W. 

 Blomfield, who also furnished the following particulars : — " The speci- 

 mens were really discovered by a very old friend, Dr. George 

 Schweinfurth, the African traveller, who accompanied me on the 

 occasion. Oddly enough the other member of our party was an even 

 older African traveller than Dr. S., viz., Mr. Francis Galtou." 



The distinctive features of this insect are the form and size of the 

 ovisac, and the curiously divided digitules to the claw, the latter being 

 a character I have not hitherto observed in any other Coccid.
