LIBUENIA LIMBATA. 61 



longer than the pronotum. Abdomen dark brown. 

 Elytra nearly twice the length of the abdomen, milky- 

 grey stained with yellowish, particularly so in the 

 neighbourhood of the claval suture. Eadial and apical 

 veins markedly spotted. An irregular spot appears at 

 the point of each clavus, and a large rough-edged 

 black band, proceeding from the costa, sweeps down- 

 wards and ends at the apical margin. 



The pupae of the genus Libumia are not often met 

 with. At first there might seem to be a question 

 whether some of these Brachelytrous forms are not 

 nymphs. They might be looked on as pupal forms 

 which are arrested in their development into imagoes. 

 But on the contrary, it is certain that they have no 

 elytral cases, and their elytra (such as they have) are 

 free to move. Moreover, they have a true neuration, 

 although in a stunted form. 



The fact that they show a complete development of 

 sex also precludes the idea of their being only simple 

 pupae. 



The neuration of the aliary apparatus in L. limhata 

 (fig. ScZ) furnishes a good general example of the 

 structure of these organs in the genus. It may be 

 seen that the punctuation does not extend to all the 

 nervures of the elytra, and that the wings are quite 

 free from these markings. 



Under-side rich brown, with brown clypeus. Legs 

 mottled with ochreous and finely pubescent. Back 

 view of the pygofer tectiform, with strong styles also 

 pubescent. 



Common throughout all Europe. Plentiful in the 

 Guildford district, and at Haslemere, on dank grass 

 and rushes.
