Deceptive Uesemhlance in Long-horned Grasshoppers. 271 



of Tricondyla rufipes Diip. (a MS. name). In this stage the 

 pronotum is already feebly twice constricted, which makes 

 it very like a CoUyris ; the coloration is the same as the 

 first stage, and the surface still smooth. 



Of the next ( ?) stage I have before me a larva taken 

 by Mr. Bryant (Depok, Java, 18 iv. 1909; now in the 

 British Museum) together with CoUyris tuberculata Mel., 

 and mistaken by him at the time of the capture for that 

 beetle. It has the pronotum with the two constrictions 

 very well pronounced, which gives it a really strong resem- 

 blance to CoUyris, which is still heightened by its pro- 

 notum being distinctly punctured in the middle and in the 

 hind portion; on the mesopleurae and the metapleurae 

 are small lobes that represent the developing wings and 

 elytra. 



The type of Westwood's Coyidylodera is a larva of the 

 next stage. Its pronotum undergoes further development 

 resulting in so complete a likeness to another Cicindehd 

 beetle, Tricondyla cyanea Dej., that Westwood incorporated 

 it in his collection of Cicindelidae {I. c, p. 419). This resem- 

 blance is produced by the whole surface of the pronotum 

 being coarsely punctured throughout, while its middle 

 swelling becomes somewhat less globose, and the hind 

 portion shghtly flattened. The rudiments of wings and 

 elytra are already well developed and occupy a dorsal 

 position, as may be seen in Westwood's figure, which is 

 fairly accurate, save two lateral spots on the pronotum 

 which cannot be seen in the type. 



Three larvae from Brunner's collection (No. 7398, Java, 

 type of Trochalodera violascens ; Nos. 20,547 and 23,947, 

 Malang, Java) belong unquestionably to the next (fifth?) 

 stage. In this stage the likeness to Tricondyla almost dis- 

 appears because the pronotum undergoes further changes : 

 its hind portion is decidedly flattened; the two constric- 

 tions and the middle swelling included between them are 

 very feebly expressed; there appears at the base of the 

 hind third an obtusangulate transverse sulcus, as well as 

 a faint suggestion of the median longitudinal line; the 

 surface of the pronotum and of the head is strongly and 

 densely punctured; rudiments of wings and elytra are 

 reaching the middle of the abdomen. The coloration is 

 also not quite like that of a Tricondyla, being violaceous- 

 • brown, and varying towards brown in other larvae; the 

 coloration of the legs remains the same as it was in previous
