4 Mr. F. P. Pascoe on some neiv or little-hiotvn 



Adamsii has the basal joint of the anterior tarsus not longer than 

 the second, and the intermediate and posterior tibiae are much shorter 

 than the corresponding parts in D. Bowringii; in the former the 

 head is broader within the two lines which extend up the front 

 from the horns, and is without the concavity which distinguishes 

 the other. 



Briefly to sum up the most prominent points, D. Wallichu is 

 distinguished from the other two by its greater breadth and its 

 turgid prothorax, and D. Boivringii from D. Adamsii by the trian- 

 gular impression on the shoulders, alwaj^s filled in by the pubescence 

 which has escaped the abrasion which is suffered by the more pro- 

 jecting parts.

SiLPHOMORPHA [Carabidse].

SiJjpliomorpha speciosa. 



S. late ovata, subtilissime punctata, viridi-purpm'eo-metallica, nitida, 

 subtus nigro-chalybeata ; antennis ferrugineis. 



ITab. Queensland. 



Broadly ovate, very minutely punctured, deep golden green, with 

 brilliant dark purple or violet reflexions ; body beneath and legs black, 

 with a chalybeate gloss ; femora greenish metallic j antennae and palpi 

 ferniginous ; eyes pale ; head finely corrugated and punctured, deep 

 violet, bordered with green in front, the lip black j prothorax veiy 

 transverse, bisinuate anteriorly, with very minute punctures, and 

 divided by irregular lines into exceedingly fine reticulations ; scutellum 

 triangular, black ; elytra lightly seriate-punctate, the interspaces also 

 minutely punctured ; body beneath finely corrugated, the penultimate 

 abdominal segment deeply emarginate ; tarsi dark ferruginous. Length 

 8 lines. 



This magnificent species is veiy distinct from any other in the 

 remarkable subfamily to which it belongs, but apparently a true 

 SdpJiomorpha. The purple or dark-violet reflexion (it is difiicult to 

 fix which colour-name is most appropriate) is more decided at the 

 base and centre of the elytra, and is also very marked at the sides 

 of the prothorax. In my collection, and I believe unique. A coloured 

 figure will be given in a supplemental plate.
