270 Mr. B. P, Uvarov on a new case of Transformative 



with two more specimens, and of Prof. R. Ebner who sent 

 me, on behalf of the Wiener Staatsmuseum, the types of 

 the insects described by Brunner, as well as some addi- 

 tional specimens of the same, and my best thanks are due 

 to them both. 



The first result I have arrived at, is, that both Condy- 

 lodera and TrocJialodera are undoubtedly larvae, with the 

 wings and elytra developed and placed quite normally for 

 larvae of corresponding stages of any Tettigoniid, and the 

 statement of Brunner (1878, p. 144), that TrocJialodera has 

 the elytra not covered by the hind-wings, is due simply 

 to a misplacement of the elytra in his type, while two other 

 specimens, also from Brunner's collection, show a normal 

 position of elytra under the hind-wings. 



At the same time, it is evident that the type of Condy- 

 lodera is a larva of an earlier stage than TrocJialodera, 

 judging by the development of elytra and wings, which 

 gives us an idea in what direction the peculiarly shaped 

 pronotum of Condylodera changes during the next larval 

 stages : this direction leads undoubtedly to the more 

 flattened pronotum of Leploderes, while all other characters, 

 and especially the shape of the head and eyes, are in 

 TrocJialodera and Leploderes quite identical. These con- 

 siderations enable me to state, without hesitation, that 

 Leploderes is only the imago of the same insect, of which 

 Condylodera and TrocJialodera represent two different 

 larval stages. 



The material before me now enables me to describe, 

 briefly, the whole course of transformation which this 

 wonderful insect imdergoes during its individual life. 



The larva of the first stage is represented by a specimen 

 from Brunner's collection (No. 18,498, " Tengger-Geb., 

 Java ") ; its pronotum is already unusually elongated, 

 but regularly cylindrical, slightly narrowed anteriorly; 

 the coloration is meta.llic dark-blue, except the reddish 

 legs with the tibiae brownish and the whole surface of the 

 body, pronotum and head is perfectly smooth. In this 

 stage the insect resembles somewhat a Cicindelid beetle 

 of the genus Collyris, as has been pointed out by Shelford 

 (1902, p. 234), but this resemblance is much more pronounced 

 in the larva of the next stage. 



The larva of the second stage is in the Oxford Museum 

 (Java), and it is the same specimen which was put by 

 Duponchel in his collection of Cicindelidae under the name
