Styphloderma asperatum. Plate 5. 



The specimen figured is a female. The male appears always to 

 have two rusty yellow spots on each elytron. The anterior and posterior 

 margins of tlie thorax are beset with minute granules, a character 

 which distinguishes it from ^S'. Icevicolle, Waterhouse, which has a 

 smooth thorax. 



Tetracha australis. Plate 17. 



This beautiful species was found far in the interior of Australia 

 in considerable numbers, by Mr. F. Gr. Waterhouse, the Curator of the 

 South Australian Museum. The figure is taken from an example sent 

 by him to the Editor. It was described in Australia by M. Castelnau 

 under the name Tetracha Waterhousei,- but specimens having been 

 sent to Europe, it was first described by Baron Chaudoir, under the 

 name T. australis. 



Casnoxia aliexa. Plate 92. 



This species has an impressed arcuate line on each side of the 

 thorax, a character in which it appears to differ from all the other 

 species of the genus. 



Percosoma sulcipenxe. Plate 1. 

 The specimen from which this insect is figured was one of the 

 same series as that from which Mr. Bates obtained his example. 



Psephexus Darwixii. Plate 26. 

 The figure is taken from the specimen described by the Editor. 

 It was taken l)y Dr. Darwin some fifty years ago in Rio Janeiro. 

 He found some specimens in water under stones. The only example 

 which has been preserved was until lately in Mr. Gr. 11. Waterhouse's 

 collection, but is now in the British Museum. 



Rhytixotus squamulosus. Plate 42. 

 This singular insect is figured from an example in Mr. Pascoe's 

 collection.
