REPORT ON TERRESTRIAL FAMILIES OF HEMIPTERA-HETEROPTERA 



By G. Evelyn Hutchinson 

 Biologist, Yale North India Expedition 



The present paper is based on the collectiim of terrestrial Heteroptera made during the 

 course of the Yale North India Expedition in Indian Tibet and the borders of Tibet proper 

 in 1932. My very best thanks are due to Dr. Hellmut de Terra for the opportunity to make col- 

 lections and observations in the little known territory traversed l>y the expedition and for his 

 continued interest in the progress of the work after the return uf the expedition. In a later 

 paper I hope to discuss in detail the ecology and zoogeography of the various elements which 

 compose the fauna of the highest inhabited zones of the Himalaya and Karakorum. I believe 

 that it will be possible to correlate many of Dr. de Terra's geological findings with the results 

 of such zoogeographic studies. Meanwhile a short zoogeographical account of the fauna of 

 the highest localities is appended to the present contribution. 



The taxonomic work here reported was begun at the British Museum in January, 1934. 

 While working in London I received invaluable help from Mr. W. E. China, who is in charge 

 of the unrivalled collections of Hemiptera at South Kensington. Mr. China spared himself 

 no trouble in assisting me, and any merit that the present paper may possess is largely due to 

 him. My thanks are also due to my friend Prof. A. Petrunkevitch for help with the Russian 

 Hterature, and to Dr. E. D. Merrill and the staff of the New York Botanical Garden for deter- 

 mining specimens of food-plants. 



The only previous work dealing with the Heteroptera of the region under discussion is 

 Distant's report (1879) on the collections made by Stoliczka during the Second Yarkand Mis- 

 sion. Most of the Heteroptera in these collections were obtained at Murree and in the vicinity 

 of Yarkand, but among terrestrial species Lamprodema hrevicolle Fieb. is recorded from 

 between Tangtse and Chagra (altitude c. 4, 200 m.) in Indian Tibet. The specimen was 

 determined by Edward Saunders and is presumably correctly named. The species is not repre- 

 sented in the present collection. 



In Oshanin's catalogue (1912) several Heteroptera are recorded from Ladak, apparently 

 on the authority of Horvath (1889), who enumerated a number of species collected by Pauli 

 "in itinere suo e provincia Ladak in provinciam Pendshab." Since this collection contained a 

 numl:)er of large brightly colored forms, some of which are known from other i)arts of the 

 western Himalayas at comparatively low altitudes, it .'^eems reasonable from the available data 

 to sujipiisc that the collection was made either in Kulu or in the Kashmir depression. As 

 the present material consists exclusively of specimens from consi(leral)le altitudes, and contains 

 no species present in Horvath's collection, the latter is not further discussed. 



The material collected by the Yale North India Expedition comprises 76 specimens, repre- 

 senting thirteen species, of which one, a species of Stictoplcura, is represented only by a 

 female and a nymph; in the absence of a male it seems unwise to attempt a specific determi-
