SYNONYMIC NOTES ON AQUATIC RHYNCHOTA. 259 



Deinostoma dilatatum (Say). 

 Belostojna dilatata, Say, New Harmony, 38 [1832?]; reprint 



in-Ann. Eep. N.Y. Agric. Soc. 810 (1858), and in Com 



plete Writ. i. 366 (1869) ; Walker, Catal. Hem. Brit. Mus. 



viii. 177 (1873). 

 Zaitha stoUii (nee Am. Serv.), Herr.-Schf. Wanz. Ins. ix. 35, 



pi. 292, f. 897 <? , f. 898 ? (1853) [Jiik Sttil and Uhler]. 

 Serphus dilatatits, Stal, Stett. Ent. Zeit. xxiii. 462 (1862) ; 



Mayr, Verb. zb. Ges. Wien, xxi. 403 (1871) ; Uhler, Bull. 



U. S. Geol. Surv. (2), v. 338 (1876). 



5. Fam. Corixid^. 

 Corixa annexa (Uhl.), Walk. Catal. Hem. Brit. Mus. viii. 199 

 (1873 j, is MS. {fide Uhler). 



6. Corixa escidenta, Motsch., Etud. Entom. v. 77 (1856) ; 

 there is no description, merely a note to the effect that the ova 

 are used for food in Egypt. A reference to this species is given 

 by Guerin-Meneville, Bull. Soc. Zool. Acclim. iv. 581 (1858). 

 [This date is usually quoted 1857, but as the seance was held 

 Dec. 4th, 1857, it is unhkely that pubHcation took place before 

 1858.] 



7. Corixa atomaria, Illiger (Puton), orGermar (Fieber). 



This name appears to be MS., as regards the two older 

 authors quoted ; the earliest description I can trace is that of 

 Fieber, Bull. Moscou, xxi. (pt. 1), 515 (1848), which is later 

 than that of C. panzeriy I.e. 515, and also than that of C. ajjinis, 

 Leach, Trans. Linn. Soc. Lond. xii. 18 (1818) ; this last name — 

 afiinis — must therefore be used. I am indebted to Dr. Puton 

 for information regarding Illiger, but I fear that with his strong 

 views upon the Law of Prescription, he will not approve of the 

 use to which that information has been put. 



The synonymy of C. affinis stands at present : — 



C. AFFINIS, Leach. 

 C. affinis, Leach, I.e. supra. 



Fieber, I.e. supra. 



Fieber, Abb. k. bohm Ges. Wiss. (v.) 7, 227, 

 pi. 1, f. 3 and 5 (1851). 

 panzeri and affinis, B. White, E.M.M. x. 61 and 76 (1873). 

 salina, Thoms., Opusc. Ent. i. 29 (1869). 

 (var.) atomaria var. eonglomerata, Rey, Rev. d'Ent. ix. 29 (1890). 

 It is also the striata of Panzer and the graphiptera of Rambur, 

 and I believe (though Renter says this equals C. geoffroyi, Leach) 

 that it is striata, Geoff"., Hist, abreg. i. 478, pi. ix. f. vii. (1762), 

 in which case ajjinis would be the type- species of the genus 

 Corixa).
