WEST INDIAN HOMOPTEKA. 51 



supposed to be the same, has only seven joints. It seen)s possible 

 that L. chirimolice, although abandoned by its author (Tr. N. Z. 

 Inst. 1890, p. 16) is a valid species after all. The legs are not de- 

 scribed by Douglas. The femur is about one-third longer than 

 tibia; tibia not twice as long as tarsus. Tarsal knobbed hairs long 

 and stout; claw short and thick. Fenioro-tibial and tibio-tarsal 

 joints dark. Hairs arise from the distal ends of the coxa and tro- 

 chanter, the trochanteric one beiu" the lontjer. 



The eggs are oval, as in other species. 



(4.) Lecanium tessellatum Sign.— A very remarkable species, 

 found hitherto in hot-houses in Europe, on a palm (Carysta). Some 

 time ago Mrs. Swainson brought me some lignum-vitse leaveS, gath- 

 ered in Kingston, Jamaica, which I then put by. Turning them 

 over later, I was surprised to find a curious flat Lecanium, which 

 agrees well with Signoret's tes-^eUatum. This example, 5 mm. lon^ 

 and 4 mm. broad, was spoiled by a parasite, which had escaped 

 through a small hole. On Dec. 29, 1892, I was so fortunate as to 

 find another scale, also on a lignum-vitse leaf, at Mr. Gardner's 

 residence in Kingston. This latter specimen was not parasitized, 

 and on removing it from the leaf, it was interesting to see a crowd 

 of young larvae, which, on being exposed to the light, scattered in 

 all directions. 



The following descriptive notes are intended to supplement those 

 given by Signoret : 



Female scale flat, very slightly convex, broad-oval or shield shaped, 

 shiny, dark chestnut-brown, strongly rugose under a lens. The tes- 

 sellations are as given by Signoret; ten sutures could be counted 

 along the margin. The posterior cleft is about two-fifths total length 

 of scale, its sides contiguous. Anal plates together forming nearly 

 a square; margin of scale slightly granulose, but no distinct hairs; 

 no lateral spines; substance of scale sparsely pitted with gland-dots. 



Legs slender, tarsus very little over one-half length of tibia; tibia 

 not much shorter than femur; two hairs spring from the distal end 

 of coxa, and apparently two from the trochanter. A young indi- 

 vidual on a leaf is flat, oval, whitish, with fine radiating grooves. 

 This example is less than 2 mm. long. 



Larva pale orange, but nearly colorless by transmitted light; 

 shape long oval, legs extending far beyond body. Last joint of an- 

 tenna with some long hairs. Tibia a Utile longer than tarsus; djo-i- 

 tules of claw curved, slender, ordinary ; clubbed hairs of tarsus
