LECANIUM FRONTALE, sp. nov. 

 (Plate LXV.) 



Adult 9 {figs. I, 2) reddish-ochreous ; median area marbled with brown, 

 the markings sometimes taking the form of broad transverse fascife. 



Eyes small, black. Form oblong, more or less acuminate at each ex- 

 tremity. Flattish ; with a slight median longitudinal ridge, a broad marginal 

 zone transversely striated with fine raised lines. Antenna {figs. 3, 4) 

 eight-jointed ; somewhat variable in size ; formula : — 3 (2, 4), 8, 5, i (7, 6), 

 or 3, 4, 5, 2, 8, I (7, 6). Legs normal ; tarsus shorter than tibia. Stigmatic 

 clefts small and inconspicuous ; spines three {fig. 5), the median nearly three 

 times length of others, and projecting beyond margin. Marginal hairs {fig. 5), 

 moderately long and fine, simple, pointed. Submarginal tubercles compara- 

 tively large, five to six on each side. Scales of anal operculum {fig. 6) broad ; 

 outer edge slightly longer than base, outer angle somewhat falcate, apical angle 

 acuminate. Derm cells minute, circular, scattered. Length 3 to 5 mm. Breadth 

 i"50 to 2'2S mm. 



Other stages not observed. 



Habitat on under surface of leaves of ' Kina ' ( Calophyllmn sp. ). 

 Pundaluoya. 



The specific name is suggested by the unusual extension of the pre-antennal 

 area. It resembles, in this respect and in general form, L. chirimolia, Mask. ; 

 but differs in the number of antennal joints (seven in Chiriniolia), and in the 

 character of the stigmatic spines which — in Maskell's species — are said to be 

 not longer than the marginal hairs.
