II.— FURTHER OBSERVATIONS ON THE GENUS 

 MARGARODES. 



By E. Ernest Green, F.E.S., F.Z.S. 



(Plates i — iv.) 



The following particulars of the life history of Margarodes 

 have been rendered possible by the discovery of fresh material of 

 the two species, papillosus and niger , by Messrs. L. C. Coleman 

 (Entomologist in the Mysore State) and T. Bainbrigge Fletcher 

 (Entomologist to the Government of the Presidency of Madras), to 

 whose assistance I am greatly indebted. 



Margarodes papillosus, Green. 



(PI. i, figs. 1-9 ; pi. ii, figs. 10-21.) 



Adult male. Colour reddish. I^egs, notal plates and eyes 

 brown. A long slender backwardly directed tuft of silky white 

 filaments on the dorsum of the abdomen, at the junction of the 

 7th and 8th segments. Abdomen subglobular, the sides inflated, 

 the ventral segments more densely chitinous. Compound eyes 

 large and prominent, involving the greater part of the head, but 

 more widely separate — above and below — than in the male of 

 M . indicus. A single ocellus on hinder edge of each compound 

 eye. Antenna (pi. i, fig. i) with 10 joints only ; the ist short and 

 broad ; the 2nd smallest, hemispherical ; the 3rd short, narrowed 

 at base, slightly longer than broad ; the remainder elongate, gradu- 

 all}'- increasing in length to the loth which is the longest ; all 

 the joints clothed with short hair. Legs well developed, with 

 strongly thickened femora, especially those of first and third limbs ; 

 anterior leg (pi. i, fig. 2) with tibia short and stout, equal in length 

 to tarsus and claw which are fused together : mid and hind legs 

 (pi. i, figs, 3, 4) with the tibiae elongated and comparatively slender, 

 equal in length to femur (minus trochanter), approximately four 

 times length of tarsus. Claw of first leg simple ; that of second leg 

 deeply bifid ; that of third leg deeply trifid (pi. i, fig. 5). The spines 

 on the outer edge of tarsus and apical part of tibia of 2nd and 3rd 

 legs are strongly thickened and compressed. Wings with only 

 two conspicuous nervures, and a denser costal area, Halcer strap- 

 shaped (pi. i, fig. 6), with a stout blunt hook at extremity, and a
