NEW SPECIES FOUND IN MYSORE 13 



active larvae. Occasionally one or two pale gi-een eggs are found but 

 this is the exception. A constant succession of larvae is produced during 

 the life of the insect. 



The newly hatched larva is pale green, of normal form, rather 

 broadly oval and very flat ; posterior extremity broadly cleft, the sides 

 of the cleft occupied by the triangular anal scales between which 

 projects a pencil of white waxy matter supported by the hairs of the 

 anal ring. The caudal setai spring from the tips of the anal scales, 

 and are nearly half the length of the body of the insect. Antennae 

 six-jointed. Feet with fouj- knobbed hairs (digitules) ; the tarsals 

 longest and one of these much stouter than the other. Marginal hairs 

 of body simple. Eyes conspicuous, black. Length 0'35 mm. 



Female of second stage similar to adult, but smaller and flatter, 

 and without the conspicuous black loop noticeable on the back of the 

 adult. 



Habitat : — Originally noticed on coft'ee (both Liberian and 

 Arabian), but now almost omnivorous. Some of the better known 

 plants upon which it occurs are : — Cinchoiaa succirubra and officinalis, 

 Citrus (various species), Tea (occasionally), Psidium guyava (guava), 

 Manihot ceara, Manihot para (Para rubber), Manihot utilisissima, 

 (tapioca) Gardenia, Ixora, Plumiei'a, and numerous garden shrubs. 

 Amongst indigenous plants, Antidesma bunius, Hiptage madablota, 

 Callicarpa lannata, Moesa indica, and sevex'al species of Loranthus 

 may be mentioned. 



The insects, in all stages, are crowddi on usually the under sur- 

 face of the leaves and on the young shoots of the plants more frequently 

 along the midribs and veins. 



The Formation of a New Species. 



Green's description no longer applies to the green bug 

 as it occurs in Mysore. Apparently a remarkable change 

 has taken place in this insect since its appearance here. 

 The earlier specimens sent in for identification answered 

 in detail to the description of Green. But when spechnens 

 received about a year later were examined, the antennal 

 joints were found to be no longer seven in number. They 

 had become reduced to three, all but the first tw^o having 

 coalesced. Several hundreds -of specimens w-ere then 

 examined from all parts of the State and from the Nilgiris 

 and the Shevaroys and all showed the reduction, though, 

 in some, faint traces of additional segmentation were 

 found. The form with seven-segmented antennae has 

 been found only on one plant in Bangalore and nowhere 

 else except, as already stated, among the specimens 

 received in 1913. 



There can be no question that the earlier specimens 

 identified as green bug answered to Green's description
