1888.] ON THE REPRODUCED TAIL OF LIZARDS. 351 



Laphris emarginatAj 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 antennte from the female sex ; these organs are longer 

 and their intermediate joints are strongly flattened and triangularly 

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

 piceous 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 melanoj)a is left out, the species is, I believe, found in Japan. 



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

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



Monolepta Jlaviventris, Motsch. (p. 755), should have been placed 

 in Malacosoma. 



According to M.Fairmaire the following species described by him 

 from China (1876) are synonyms: — 



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



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



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



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



By G. A. BOULENGER. 



[Received 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 uf 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 Lacertidse, Gerrhosauridse, and Scink-like Auguidae, so far as 

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