are difficult to find and, being very active on the wing, make 

 their es^c.ipe as soon as the |>lant is disturbed. I was fortunate 

 in capturing one pair iii coita, and confined them in a glass jar 

 with some young shoots of the plant. A few days later I found 

 several eggs embedded in the fleshy stalks. They are deposited 

 singly, the body of the egg completely concealed (fig. 4), the

position marked — as with the eggs of Helopeltis* — by a pair of 

 delicate, glassy, horn-like processes. The complete egg (fig. 8) 

 might easily be mistaken for that of Helipeltis, the principal 

 difference being that the two processes are usually divergent 

 instead of convergent. The longer process has a knee-like bend 

 shortly above the base. The cap of the egg is delicately pitted. 

 The body of the egg is smooth, curved, elongate, of a pale 

 creamy white colour. Length, 1*50 mm. Breadth, 25 mm. 

 Longer process, 0*50 mm. Shorter process, 0*20 mm. 



Anoplocnemis phasianus (Fabr.). 

 Both the adult and immature insects occur frequently on the 

 young shoots of Erf/thrina lithosperma. They puncture the 

 extremities of the shoots, causing them to wilt and wither. I 

 noticed, one day, an adult male apparently feeding, and ap- 

 proached it to observe the modus operandi. The bug, however, 

 resented the intrusion, and ejected a jet of fluid backwards to a 

 distance of fully eighteen inches. The jet appeared to proceed

N.B. — Mr. Albert D. Michael has kindly examined the parasites 

 tnentioued above as being fouud on Anioir/ius imlicti, and deterruiups 

 them provisionally as larvae of Hi/drdchnn belosiomcB, Riley (adult 

 HijdnicIuKB are not parasitic). In reply to my note, pointing out that 

 the American Amnifjins is a different species from the Sinhalese one, 

 and asking whether the parasite of the former is actually conspecific
