ON THE SPECIFIC DISTINCTNESS OF CORIXA CARINATA 

 AND C. GERMARI, AND THE RESTORATION OF THE 

 LATTER TO THE LIST OF BRITISH RHYNCHOTA. 



By G. W. Kirkaldy. 



One of the two British species of Corixa with a longitudinal 

 central percurrent carina on the pronotum, enumerated by 

 Saunders (Hem. Het. Brit. Isl., 1892, p. 340), is carinata, com- 

 prehending carinata, C. R. Sahib., sharpi, Dougl. and Scott, 

 intricata, D. & S., and also (not mentioned by Saunders) germari, 

 Fieb , and variegata, Wallengr. There are certainly two distinct 

 species amongst these, though the synonymy cannot be positively 

 given until the various types have been re-examined. Some time 

 ago, while reading White's "Notes on Corixa"'' (1873, Ent. Mo. 

 Mag. x. p. 60), I remarked that he there describes the strigil in 

 G. sharpi as being composed of " eight broad rows," that of 

 G. intricata as having " about sixteen rather narrow and very 

 irregular rows." This I have confirmed by an examination of 

 examples in White's collection (recently presented by Mr. T. M. 

 M'Gregor to the Perth Museum), which were received by him 

 from Mr. Douglas. The only other differences that I can find 

 are in the frontal fovea of the male, and perhaps in the palaB. 

 It is not very easy to adjust the synonymy, as I have not seen 

 any original examples of the other species, and little is to be 

 gathered from most of the descriptions. 



Sahlberg's original description of carinata (1819, Hist. 

 Notonect., p. 12) applies equally well to either. Fieber's carinata 

 is not Sahlberg's species, as is well known, but that described 

 later by Thomson as cavifrons, while his germari is not separable 

 by the brief description in the Bull. Soc. Nat. Moscou (1848, 

 xxi. 1, p. 531) ; his later descriptions in Abh. bohm. Ges. Wiss.
