ground. T. nniiina, a small form, was fairly numerous, one specimen 

 captured was of considerable interest, being without any red markings on 

 the upper surface of the forewings. Ij/rania [Viihjduniiatiis) icanis, ['. 

 (laplitlircand Hphit'iiJiclc i>asiiiha'r, were fairly numerous. I before reaching 

 Palo there is a little stream, and I worked for some miles up both its 

 banks, which were clothed with a luxuriant growth of the oleander. 

 On the grassy slopes of the right bank T. halliis was very common. 

 The left bank, the locality furnished me hy Mr. Sheldon, was more 

 productive, but a divergence was necessary to reach the lower slopes 

 of the somewhat distant hills. Ascending about 1,000 feet cultivation 

 was not so acute, flowering plants were more numerous growing 

 among various trees and shrubs ; butterfly life was here quite well 

 represented. Ijjcaena {(jlaiiropsi/rln') )nclanops, a large and fine form, 

 was common, but unfortunately had seen its best days ; one specimen 

 of Lycaeiut (^Ai/riadi's) bi'Uaiy/iis (tlwtis) var. (rr())tiis was my best 

 capture in this locality.

"The Latest in Nomenclature." 



By G. T. BETHT'NE-BAKER, F.L.S., F.Z.S., F.E.H. 

 I think Mr. Shelford's article on the nomenclature of the genus 

 Stelenpjp/na is entirely met by the International Code on the subject. 



The code would deal with the matter thus : — 

 1st. Fischer von Waldheim erected the genus for three species — 

 orientalis, L., amcrivana, L., and trichoprocta, sp. n. (1833). 

 Latreille had already (1810) selected oricntalis, L., as the type 

 of the genus lUatta. Fischer von Waldheim's action in 

 including that species was therefore ultra vires: nrinitalh,lj., 

 is consequently eliminated, leaving a)iu'ricaiia, L., and tricho- 

 procta, F. V. W., only in the genus. 

 2nd. Brulle erected the genus Pali/p/iaiia for aci/i/ptiaca {i.e., tric/io- 

 procta) (1835). 

 This eliminates tric/mpidcta [acip/ptiaca) and leaves a)iiericana 

 as the type of Stclcdpi/i/jia, which cannot be altered. 

 3rd. Americana was made the type of I'criplaneta, Burm, 1830. The 

 species having already become the type of Stclcopipjua by 

 elimination, I'criplaitcta sinks to that genus, as Mr. IShelford 

 says. 

 4th. Sti/Iopj/rpia (1846), an amended name erected by Fischer von 

 Waldheim for oricntalix only. 

 This raises two points according to the International Code: — 

 {(() An author having once published the name of a genus 



has no power to alter it. 

 [h) In this case, whether the authoi' intended to amend the 

 original name is not the point, he definitely named 

 orientaliti as the type of Sti/lopip/iia, and therefore 

 the name sinks to Blatta,

 The questions raised or suggested by Dr. Chapman's article {antca, 

 p. 239) are by no means unimportant, and the ultimate issues of progress 

 along the lines he has indicated would be more far-reaching than
