264 REVISION OF THE AUSTRALIAN SPKCIES OF ADELIUM, 



Wales, and extends at least to Rockhampton, from both of which 

 districts I have specimens. 



A. congestion Pasc. = Seirotrana parallela Germ., and will be 

 more fully referred to in my notes on Seirotrana. 



A. latum Pasc. — This appears to me to be only a variety of A. 

 abbreviation, though possessing certain distinctive characters of 

 doubtful specific value(see Champion's note, Trans Ent. Soc.Lond. 

 1894, p.402). I have two specimens labelled Melbourne. Mr. 

 Champion's specimens were taken by Mr. J. J. Walker at Laun- 

 ceston, Tas. Pascoe's locality was Victoria. 



A. obesum Pasc. — Though closely allied to A. similatum Germ., 

 the differences are well marked. It is in general larger, more 

 robust, more convex, with the prothorax much more widely 

 rounded at the sides, with a corresponding constriction at the 

 base, than Germar's species. The foliation at the sides is also 

 much more explanate, the sculpture of the pronotum is less 

 rugose, and the elytral intervals more convex, while the punc- 

 tures in the striae are more regular. I have several specimens 

 from the Preston Reservoir, Melbourne. 



A. striatum Pasc. = A. viridipenne Macl. — The largest Austra- 

 lian species and well known in all collections. The tropical form 

 has a greenish tint, hence Macleay's species, but there is no other 

 perceptible difference between them. I have black specimens 

 from Mackay, Q.; also a cotype of Macleay's viridipenne, with 

 a specimen that is intermediate in colour between them. These 

 vary in size from 19 to 25 mm. long. There is a large striate 

 form close to A. striatum in the Bates Coll., marked with an MS. 

 name of Bates' from the mountains of Tasmania, but this is 

 possibly a mistake of locality. 



A. vicarium Pasc, is the common form to be found near Perth, 

 W.A. 



A. aerarium Pasc. — The only specimen I have seen of this is 

 the type (unique). It is very close to A. angurale Pasc, but is 

 of a brighter green colour, is smoother, and has more parallel 

 sides to the prothorax.
