quin bug of Australia, Dindymus versicolor, is a Pyrrhocorid and 

 punctures ripe fruits. 



Tingitidce. 



Urentius echinus Dist. occurs on egg plants in India, though not 

 as yet troublesome. The olive tree bug, Froggattia olivina, of 

 New South Wales, has turned its attention from the wild to the 

 cultivated olives, sometimes defoliating the trees. Stephanitis 

 (Tingis) pyri Fabr., which inhabits Europe, Asia Minor, Russia, 

 Japan, etc., is injurious to foliage of pear and is mentioned in most 

 European works on economic entomology. 



Capsidce. 



In this extensive family, the species mostly live on plants and a 

 few are of importance. The famous mosquito blight of tea in 

 India and Ceylon is due to Helopeltis theivora Waterhouse while 

 H. bradyi Waterhouse injures cacio in Java. Disphinctus politus 

 Walker attacks the betel vine and D. humeralis Walker injures 

 Chincona, in India. Gallobellicus crassicornis Distant, is a garden 

 pest in Bombay, and in Pusa, attacks and breeds on tobacco. 



Calcoris angustatus Leth. attacks sorghum in South India. 

 C. trivialis Costa injures the olive, vegetables, etc. in portions of 

 southern Europe, and is present over northern Africa. 



HOMOPTERA. 



Cercopidce. 



The Cercopidse, though not numerous in species, are widely 

 distributed over the world, though not many are troublesome to 

 crops. 



Tomaspis varia Fabr., the sugar-cane frog hopper, is just now at- 

 tracting considerable attention in Trinidad and Tobago. The 

 young feed on roots of the sugar-cane plant, following these in 

 cracks in the soil, and the adults feed on the the leaves. T. postica 

 Walker occurs on sugar-cane in Mexico. Philcenus spumarius L. 

 injures the sugar beet in Bohemia. Ptyelus costalis Wk. is a pest 

 of rice and sugar cane in Formosa. 



JassidcB. 



This family has been but little worked in the newer parts of the 

 world, though a few important species are to be mentioned as 

 crop pests. Nephotettix apicalis Motsch. is a serious enemy of rice 

 in seed beds in Japan and Formosa, and has caused a loss of $10,000,- 

 000 in a single year. The species ranges over Japan, China, Cey-
