they get darker in color. In the early stages they feed at the 

 bases of the leaf petioles, but later migrate to the branch^ 

 and main stems, where they apparently regain and complete 

 development. Both the nymphs and adults are attended by 

 ants and in our cages ants* were observed at various time's 

 carrying fifth stage nymphs and an adult, although no action 

 of this kind was observed in the field. Mann ( Psyche xxii. 5, 

 162, 1915) writes as follows, "Fnslin has recently observed 

 (Zeits. f. wiss. Insrktcnbiol. vol. vii. pp. 19-21) that the Euro- 

 pean ant Formica cincrca F., often carries into its nests nymph. 

 and adults of (,'arf/ara f/cnistac F., a common Furopean Ilomop 

 teron. Those which he observed soon died, probably because 

 of lack of food in the subterranean nests of the i Both 



adults and nymphs are sluggish and readily captured. When 

 disturbed they move around to the side of the twig away from 

 the observer. The adults scatter considerably and may In- 

 found on all parts of the plant resting, usually on the twi^s. 



Egg. Length, 1.1 mm. Width, 0.31 mm. Whitish, translucent, ob- 

 tusely rounded at one end, tapering to an acute angle at opposite end. 

 Sides almost parallel from rounded end to about three-fifths of length, 

 then gradually tapering to acute tip, with one side slightly flat. Alco- 

 holic specimens show granulated appearance beneath chorion. 



First Stage Nymph. Length, 3 mm. Width of head, including eyes, 

 0.6 mm. Form elongate, thoracic and first abdominal segments of 

 about equal width, from which the body tapers posteriorly to acute tip. 

 A transverse section would be triangular with median dorsal portion 

 somewhat ridged. 



Head transverse dorsally, about four times as broad as long, extend- 

 ing ventrally to first pair of legs. Eyes prominent, lateral. Antennae, 

 bristle-like, on ventral side of head between the eyes, three-jointed, two 

 basal joints sub-quadrangular, apical joint long and narrow, tapering to 



tip. 



Prothorax somewhat longer and broader than head with sides lobcd. 

 Mesothorax slightly shorter and broader than prothorax. Metathorax 

 slightly shorter than mesothorax at centre and about same width. Pos- 

 terior margin of metathorax slightly concave and sinuate at centre. 

 Lateral lobes of thoracic segments, especially those of meso- and meta- 

 thorax, extending somewhat posteriorly. 



Abdominal segments two to seven, short and broad and of about
