XXIII. RHYNCHOTA FROM THE GARO 

 HILLS. ASSAM. 



By C. A, Paiva, Assistant, Zoological Survey of India. 



(Plates XXXIV-XXXVI). 



[In this paper Mr. Paiva gives an account of a collection of 

 Rhynchota (excluding the smaller Homoptera) made in the Garo 

 Hills between June and October, 1917, by Mrs. Kemp and myself. 

 The specimens were for the most part obtained in two localities : 

 at Tura, the headquarters of the Garo Hills district, at an alti- 

 tude of 1,200 to 1,500 ft., and on the summit of the ridge imme- 

 diately above Tura at altitudes varying from 3,500 to 4,000 ft. 

 Although these two localities are less than five miles distant from 

 each other there are marked differences in the fauna. The differ- 

 ences are no doubt due mainly to the change in altitude, but may 

 to some extent owe their origin to the different nature of the 

 country in the two localities. In the neighbourhood of Tura the 

 Garos have made extensive clearings for cultivation and the country 

 consists of open land and low scrub interspersed by patches of 

 ancient forest. On the range above Tura no cultivation has ever 

 been attempted and the hills are entirely covered with high tree- 

 jungle, often almost impenetrable in its density. As might be 

 expected, it is from the latter region that the more interesting 

 forms were obtained. Mr. Paiva has found in the collection a 

 considerable number of forms hitherto known only from the 

 Eastern Himalayas and has described as new two genera and 

 eighteen species. Among the latter is a very curious caverni- 

 colous Reduviid recently obtained by Mr. R. Friel, I.C.S., in the 

 Siju Cave on the borders of the Garo Hills and Mymensingh dis- 

 tricts. — S. W. Kemp.] 



Family PENTATOMIDAE. 

 Cantao ocellatus (Thunb.). 



Five specimens from above Tura, 15.vii-31.viii.1917 ; three 

 specimens from Tura, 1,400 ft., x.1917. 



Those collected in July and August are dark reddish ochra- 

 ceous, while those collected in October are pale yellowish 

 ochraceous in colour. 



Found all over India.
