LECANIUM. 13 
15. Lecanium nocturnum, Ckll. & Parrott, sp. n. 
Closely allied to Z. phoradendri, Ckll., from Arizona. 
2. Scale broad-oval, moderately convex, rather rough and somewhat dull, black, irregularly mottled in the 
subdorsal region with reddish-brown or dull orange ; or occasionally all black. Length 4 millim., breadth 
nearly 33, height 1. 
Young scales are dull olive-green, usually mottled with blackish. 
The female after boiling in caustic alkali becomes translucent, and presents a submarginal light brown granular 
area, on which are many large rounded hyaline spots. (In L. phoradendri the light brown area is much 
further from the margin, and does not show large hyaline spots, but only scattered hyaline dots.) Marginal 
spines simple, very slender. Stigmatal spines in threes, the middle (long) one 42 to 56 yu long, the others 
11 tod6p. Digitules ordinary; those of claw stout, of tarsus filiform. Antenne 7-segmented. One 
abnormal antenna was only 6-segmented, with segment 6 53 p long. 
Newly-hatched larva (dried) olive-green, with a dark dorsal shade. 
3. Scale glossy, as usual in the genus, with a faint greenish tint; two transverse sutures on each side and 
two at the anterior end.

Hab. Mexico: Alvarado in Vera Cruz, April 22, 1892, on a bush called “ huele de 
noche” (Townsend). 
The scales are numerous on the bark. 
16. Lecanium (Saissetia) inflatum, Ckll. & Parrott, sp. n. 
Q. Scale very convex, subglobular; 11 millim. long, 73 broad, 7 high, varying to 83 long, 6% broad, 64 high. 
Coffee-brown of various shades, sometimes quite a pale (café au lait) colour, fairly shiny, more or less 
pruinose with white powder, smooth, under a lens seen to be minutely and very closely spotted; extreme 
sides inclined to be roughened or slightly malleate; margin blackish. 
Skin with the polygons of Saissetia, these almost circular, diam, 22-33 4; some are oval, 44 x 25 u, with the 
central gland 16 x 22 py. 
Antenne and legs rudimentary. Antenne 157» long, short and thick, segmentation obscure, end broadly 
rounded. Last segment 16 » long, 18 broad; penultimate one 14 long, 24 broad; second from last 
14 p long, 40 broad; third from last 41 p long, 66 broad. Legs thick and short, femur 59-70 p long, 
70 p at broadest; tibia 42 u long, 36 broad; tarsus 28-33 w long, 28-86 » broad at base, 22-25 at end; 
claw stout and hooked, 14 p long. 
3. Scale flattened, transparent, glassy, with a well-defined dorsal area, crossed about the middle of the 
posterior half by one suture; the usual two transverse sutures on each side from the dorsal area to 
the margin, and the pair of anterior sutures. 
3. Scarlet, with strongly iridescent wings; costal nervure pink. 
Hab. Mexico: Coatzocoalcos in Vera Cruz, April 24, 1898, on large tree calied 
“laurel” (Townsend). 
The female scales occur on the branches, the males on the leaves. This is a globular 
species with the skin of a Saissetia, recalling L. verrucoswm, Signoret.
