74 ME. W. V. KIEBT ON THE 



This list was reprinted, almost verbatim in 1863, by Motscbulsky 

 (Bull. Soc. Imp. Nat. Moscou, xxxvi. (3) pp. 74-115), wlio added 

 descriptions of 28 new Hemiptera and 28 new Homoptera, besides 

 giving references to 3 more Hemiptera and 10 Homoptera pub- 

 lished by himself in his ' Etudes Entomologiques,' viii. (1859), 

 pp. 108-115. He makes scarcely any other additions to Walker's 

 list ; but the localities of his own new species are, in most cases, 

 carefully indicated. 



A much better list of the Hemiptera Heteroptera of Ceylon 

 was, hovi^ever, published by Anton Dohrn in 1860 in the Stett. ent. 

 Zeit. xsi. pp. 399-409. He enumerates 112 species, of which 

 39 are described as new. However, this list likewdse contained 

 a number of MS. species. 



In the present paper, which I believe maybe regarded as fairly 

 complete, I have raised the number of described Cinghalese species 

 of Hemiptera Heteroptera to 285 (38 new), and of Homoptera to 

 187 (59 new).* In accordance with my usual practice in faunistic 

 papers, I have abstained from describing many new genera, and 

 I avoid long descriptions, as far as possible. The species are 

 grouped under the more important families, smaller subdivisions 

 being omitted. 



All the species in the following list of which the British 

 Museum possesses specimens from Ceylon are marked (*), and 

 all those contained in Mr. Grreen's collection are marked (t) . 

 Some of the latter had been labelled, and one or two described, 

 by the late Mr. Atkinson. I am indebted to Mr. Green for in- 

 formation respecting the habits, localities, &c. of several species ; 

 and these paragraphs are marked with his initials. 



Hemiptera Heteeopteka. 

 Pentatomid^. 



r *f CaJSTTAO OCELLATUS. 



Cimex ocellatus, Thunb, Nov. Spec. Ins. p. 60, f. 72 (1783). 

 A very common and variable species throughout the Indo- 

 Malayail region. It is gregarious, and often found in numbers 

 (20 or 30 together) collected on a single branch of a tree 

 (^. E. G.). 



* It will be noticed that two or three of these species have been recorded 

 from Ceylon on somewhat doubtful authority, and their actual occurrence in 

 the island requires confirmation.
