establishing a large colony of them on ivy, and it is hoped that some 

 interesting facts in regard to the economy of the species may be 

 observed. 



LiCHTENsiA Eatoni, n. sp. 

 ? adult (? Tiviparous), elongate-ovate, or short-ovate. The form of the insect 

 did not restore very well in potash. Antennae (fig. 1) of eight joints ; 2, 3 and 4 



nearly equal, and longest ; 5, 6, 7 and 8 shorter 



and subequal ; 1 is shorter on one side than 



the other ; there are several rather short hairs 



/Ti Vs./ I n arranged as shown in fig., but I could find no 



»> /u \ r / trace of one at the extremity of the last joint. 



Legs stout (fig. 2, posterior leg) ; anterior 

 pair shortest, have the tarsi (fig. 3) constricted 

 in fi'ont, which is constant but variable in 

 character and position ; in some it is very 

 decided, darker, and looks stronger ; in others 

 these latter characters are entirely wanting ; 

 the rest of the constriction in every case is 

 only indicated by a faint line extending to 

 about the middle ; in one instance only did it 

 extend to the under-side. The intermediate 

 and posterior legs show no trace of the con- 

 striction in the tarsi (fig. 4, posterior tarsus) ; 

 tarsi much shorter than tibiae ; digitules of the claw very long and much dilated at 

 apex ; those of the tai'si ordinary. Mentum monomerous ; unexpanded filaments 

 about the same length as anterior legs, but are often much shorter. Anal ring with 

 eight very long hairs, and a double row of circular discs. Margin all round with 

 a single row of short spines, arranged close together, but scarcely visible under a 

 one-inch objective. Anal cleft ordinary ; anal dorsal lobes each with a few hairs on 



inner margin and two at apex ; one longer and stouter than the other. 



Long, 5 mm. ; wide, 2'5 mm. 



Sac of the $ complete, white, closely felted, slightly naiTowed in front, where 

 it is somewhat flattened, and has, generally, three longitudinal carinse ; the rest 

 convex. Long, 4'5 — 5 mm. ; wide, 25 — 3 mm. 



(? scale glassy, white, with a strong central elevated keel, opaque on the edge, 

 transparent at sides, where it is longitudinally striate. Commencing at the base of 

 the anal cleft, and extending along the sides at the base of the keel, to the margin 

 in front, are two divergent, white, slightly raised carinae ; three other of these white 

 carinse, arranged transversely and equidistant, are most conspicuous on the broad 

 flat margins. Long, 2 mm. 



Hah. : on olive ; Constantine, Algeria ; altitude, about 2000 feet.

It has been necessary to enter into most careful detail in the de- 

 scription, and also to give figures drawn to the same scale, both of 

 this and the preceding species, in order to point out the salient 

 characters of each. It will be seen that this species possesses many
