Inglisia malvacearum , sp. n. 



$ . — Scale 7 raillim. long, 3^ broad, only moderately 

 convex, general shape oblong, snow-white, very conspicuous ; 

 presenting on the dorsal surface two large conical (patelli- 

 ibrm) plates and on each side about four similar but lower 

 plates, not well separated from each other ; posteriorly the 

 plate-structure gives way to a fibrous substance resembling 

 the tissue of the ovisac of a Lichtensia. The plate-structure 

 cannot be described in great detail, because it is more or less 

 irregular and quite variable within certain limits. The 

 plates ajipear to be joined together by the fibrous matter. 



$ . — Dermis after boiling colourless, with small round 

 glands; margin with a row of brownish spines, short but 

 stout, blunt-tipped, on tlie average about as far apart as the 

 length of one. Autennai and legs well developed, yellowish ; 

 antenna of the ordinary Lecanid type, long and slender, 

 8-segmented, 3 considerably the longest, formula 3 5 4 

 (2 6 7 8) 1 or 3 5 (4 2 G 7 8) 1 ; 5 has a pair of bristles, one 

 very long, near its end ; 8 has several bristles. Legs mode- 

 rately slender ; coxa long, with two anterior and one ]josterior 

 apical bristles ; trochanter with a large and a small bristle 

 near its apex ; femur with anterior and posterior subapical 

 small bristles; tibia not much shorter than femur; tarsus 

 about ^ length of tibia ; claw short and much curved ; claw- 

 digitules rather stout, very short, not so long as claw ; tarsal 

 digitules apparently absent. Tiiese details were from an 

 anterior leg ; a hind leg showed digitules of claw stout, 

 well-knobbed, extending beyond claw, and tarsal digitules 

 filiform but strong, quite long, with well-tormcd knobs. Anal 

 plates yellowish brown, of the usual form, postero-latcral side 

 a little longer than antero- lateral, surface armed with about 

 iive bristles. Anal ring with seven hairs. Mouth-parts 

 rather small. 



The conical protuberances of the scale are glassy, concen- 

 trically striate, with the usual air-cells of Inglisia-y the lateral 

 portions of the scale have a fibrous structure. 



J. — Scale glassy, small, resembling the ordinary male 

 scales of Lecanium.
