towards the extremities ; rather thia and transkicent towards 

 the edges. Margins bearing short, fine hairs, not set closely 

 together. Viewed dorsally, the eyes appear near the cephahc 

 extremity; viewed ventrally, the antennae are placed a long 

 way from the extremity, and the rostrum, between the first 

 pair of legs, is almost at half the whole length. Epidermis 

 exhibiting small, sparse, oval spots, very inconspicuous, irregu- 

 larly arranged. Mentum uni-articular. Eyes duplex ; outer 

 portion orbicular, slightly prominent, yellow, resting on a 

 broadish black base. Spiracular spines not longer than the 

 rest. Antennae slender, of seven joints — the fourth the 

 longest, the third next, the first fifth and sixth the shortest, 

 the seventh fusiform and bearing several hairs. Feet slender ; 

 the tibia is slightly dilated at the end, and bears a spine ; 

 upper digitules tine hairs, lower pair somewhat dilated. The 

 abdominal cleft is very long and narrow ; the two dorsal 

 lobes small, rather sharply triangular, and closely ad- 

 jacent. 



Second stage of female resembling in general form and 

 colour the adult, but smaller and fiatter ; length averaging 

 Y^2^in. AntenntE of six joints. 



Larva light-brown, elongated, elliptical ; length about ^Vin., 

 convex above, flattish beneath; not clearly segmented; on 

 the margin a few hairs, the spiracular spines no longer than 

 the rest, as m the adult. Antennae of six rather thick joints, 

 subequal, the third joint a little the longest ; all the joints 

 dilated at the ends, except the last, which is fusiform ; a few- 

 hairs on all the joints, and on the sixth several, of which four 

 are very long — as long as the whole antenna. The feet pre- 

 sent no special features. 



Male unknown. 



Hab. In Fiji, on both bark and leaves of chirimoya — 

 Annona (CJuriniolia) tripetala. 



In colour, and in the sparse markings of the epidermis, 

 this insect resembles L. hespcridum, Linn. ; but from its 

 elongation and slenderness it belongs to that series of the 

 genus Lecanmvi of which Signoret takes L. persicce as the 

 type. It differs, however, from all described species of that 

 series. L. cloujatum, Sign., is much larger, is rugose at the 

 edges, and has, moreover, eight-jointed antennae ; so also has 

 L. gcnistcB, Sign. The long, narrow abdominal cleft of L. 

 chirimolio}, the sharp adjacent dorsal lobes, and the short 

 spiracular spines seem to be specific distinctions ; and the 

 distance of the antennae from the cephalic extremity is also 

 peculiar. I am not aw\are whether the chirimoya is a plant 

 indigenous to Fiji : if it has been imported there from Central 

 America it has probably brought its Lecanid with it.
