1888.] ON THE REPRODUCED TAIL OF LIZARDS. 3.^1 



Laphris emarginata, Baly. 



Of this species there are a few examples contained in the present 

 collection, amongst which is a male, which differs considerably in the 

 shape of the antennae from the female sex ; tliese organs are longer 

 and their intermediate joints are strongly flattened and triangularly 

 dilated, although of the same elongate shape ; the broad, black or 

 piceoiis band of the elytra is occasionally of nearly equal width 

 instead of being deeply emarginate at its middle as in the type. 



Notes. 



In my catalogue of Japanese Phytophaga (Proc. Zool. Soc. 1885, 

 p. 752) several mistakes and omissions have been made, which I 

 will here rectify, thus : — 



Lema melanopa is left out, the species is, I believe, found in Japan. 



Adimonia muUicostata, Jac. (p. 755), is identical with Galerucella 

 punctatostriata, Motsch. ; the species belongs, however, to Adimonia. 



Monolepta fai'iventris, Motsch. (p. 755), should have been placed 

 in Malacosoma. 



According to M. Fairmaire the following species described by him 

 from Ciiina (1876) are synonyms : — 



Paralina impressiuscula, Fairm., = P. fallaciosa, Stal. 



Lina ignitincta, Fairm., = Galeruca fulminans. Men. 



Anthraxantha davidis, F., = Mimastra cyanura, Hope. 



3. On the Scaling of the Reproduced Tail in Lizards. 



By G. A. BOULENGER. 



[Eeceived June 5, 1888.] 



It is a well-known fact that in such Reptiles as have the power of 

 reproducing the tail, the scaling of the renewed portion often differs 

 considerably from that of the normal organ. It is generally held 

 that the difference consists merely in the irregularity of the scaling, 

 or in the absence of certain tubercles or enlarged scutes which are 

 characteristic of the species. Such a view is erroneous. I have 

 convinced myself that, in some cases, the aberrant scaling of the re- 

 produced tail is a reversion to an ancestral form. 



That a tail with heterogeneous lepidosis may be reproduced as such, 

 is shown by Hatteria ; the dorsal series of compressed tubercles, so 

 strikingly similar to that of Chelydra, is present on the reproduced 

 portion, which differs only in the scales not being verticillate. 



That a tail with uniform scaling may be reproduced with diver- 

 sified scales is exemplified by a large number of Scincoids and some 

 Geckoids, which, having a tail covered with subequal scales, develop 

 on the new portion a ventral, or both a ventral and a dorsal, series 

 of large transverse scutes, such as exist normally in other species of 

 the same or of allied genera. 



All Lacertidee, Gerrhosauridse, and Scink-like Anguidse, so far as 

 I am aware, reproduce a caudal scaling true to their type.
