times as long as tarsi, first tarsal segment one-fifth longer than 

 second, which is twice as long as the large falciform claws. Length 

 4J mill., width 1-9 mill. 



Australia, Albany (Perth Museum, Scotland, and my collec- 

 tion). 



Black, opaque ; with golden pubescence, abundant on pronotum 

 and scutellum, more sparingly on head and elytra. Eyes and ocelli 

 yellowish. Two basal segments of antennae obscure yellow (black 

 underneath the first, except at apex), two apical black, with golden 

 pile. Rostrum obscure brown. Elytra : a luteous spot close to the 

 internal suture of the clavus ; two elongate flavescent spots on the 

 exterior margin, and three or four smaller spots on the disk, of the 

 corium. Membrane transparent flavescent, except a black blotch at 

 the base near the exterior margin, and another towards the apex ; 

 nervures brownish with obscure centres. Legs yellowish ; coxaa, 

 femora ventrally (except the basal half of the posterior pair), tibial 

 and tarsal spines, anterior tibiae narrowly at base and apex, black. A 

 faint brownish smudge dorsally, in the middle, on the anterior tibiaa. 

 Ventral surface black, apical margin of sterna and abdominal segments 

 very narrowly (sixth segment very broadly) yellowish. 



I dedicate this handsome little species to Dr. 0. M. Reuter, 

 who has made such a laborious study of the difficult palsearctic 

 species. I believe that Acanthia will be found to inhabit the 

 tropics much more commonly than has hitherto been supposed. 



The ninth "Band" of Hahn and Herrich-Schaffer's ' Wanzen- 

 artigen Insecten ' is dated 1853 on the title-page, and this date 

 has been generally accepted by modern authors. The greater 

 part, however, was apparently published at least one year earlier, 

 and I have reason for supposing that each "Band" may have 

 been published in several separate "Hefts." I call attention to 

 the matter here, as possibly someone may still be in possession 

 of the original covers. 



On pp. 47-8, Schiiffer, in dealing with the genus Corixa, says 

 that he has only just seen Fieber's synopsis of the European 

 species (Bulletin Soc. Imp. Naturalistes de Moscou, p. 505) pub- 

 lished in 1848, and, as his coloured plates were finished long 

 before, he has not altered his manuscript. 



Now, it is almost incredible that an entomologist, student of 

 the Rhynchota from 1829 at least, and therefore presumably in 

 communication with other rhynchotists, should — writing in 1853 

 — be only just aware of an important work published in 1848, 

 and apparently quite ignorant of Fieber's three still more im- 

 portant papers published in 1851 in the ' Abhandlung Bohm. 

 Gesell. Wissensch.' 



Dallas, in the second part of his ' List of Hemiptera in the 

 British Museum,' dated 1852, quotes the ninth Band of 'Die 

 Wanzenartigen Insecten' as 1850 for some pages {i.e. 232, 237,
