26^ tHB CANADIAN ENTOMOLOGIST. 



dark brown, more or less shiny ; sides with Hnear pUcations. Boiled in 

 caustic soda turns the liquid yellowish-brown. Antennse pale, well- 

 developed, tapering, ordinary, 7-jointed, formula 32 (17) 5 (46); 3 

 extremely long, considerably longer than 4 to 7 together ; 2 about as long 

 as 4 + 5 ; a faint false joint marks the basal 34^ of 3 ; i, 2 and 3 each 

 with a pair of bristles, on i and 2 about the middle, on 3 near the end ; 

 7 with several hairs, an especially long one, longer than itself, springing 

 from its base. Rostral loop short. Anal plates yellowish-brown, the 

 caudolateral margin somewhat shorter than the cephalolateral. Legs well- 

 developed, pale. Digitules filiform, with large knobs. Tarsus hardly 

 half length of tibia. Derm not reticulated, with sparse small round or 

 oval gland orifices ; a broad marginal area with very large round or oval 

 gland-pits, the derm between them exhibiting a faint tendency to minute 

 reticulation. These large giand-pits are double or more often complex ; 

 they are often nearer together than the diameter of one. 



Embryojiic larva (after boiling) pale yellowish-brown ; rostral fila- 

 ments in two coils. Caudal tubercles not or little projecting beyond body 

 margin, though well-developed. Anal ring with six hairs, its broad margin 

 conspicuously striate. Claw long ; digitules of claw filiform, distinctly 

 knobbed, extending beyond tip of claw; tarsal digitules stouter, with very 

 distinct knobs, not nearly twice as long as claw-digitules, their origin some 

 distance basad of base of claw. 



Hab. — Xcolak, near Izamal, Yucatan, Mexico, March loth, 1896. 

 (Townsend: Div. Ent., No. 5663.) This is a most interesting species ; 

 the first Eidecanium ever found in the tropics. The antennse are like 

 those of L. antennatum, Signoret. The compound submarginal glands or 

 pits remind one of the large double glands of L. Fletcheri. On the other 

 hand, the large pits of the neotropical species Z. baccharidis (from Brazil) 

 and L. batatce (from Antigua) are at once suggested, and it seems that we 

 have here an indication of the affinities of these two species, which had 

 been heretofore wholly obscure. Z. perdiium presents some superficial 

 resemblance to small examples of Z. depressum or begonice, but these 

 belong to a quite different section. 



(6.) Lecanium chiiaspidis, n sp. — $ very dark brown, shiny, but 

 largely encrusted (especially at sides) with a dull dark grayish substance ; 

 strongly convex, long. 81^, lat. 6, alt. 5 mm. Beneath, at the lateral 

 (spiracular) incisions, are conspicuous patches of white secretion, only
