26 Mr. F. P. Pascoe on some new or little-known 
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. Wallichii is 
distinguished from the other two by its greater breadth and its 
turgid prothorax, and D. Bowringii from D. Adamsii by the trian- 
gular impression on the shoulders, always filled in by the pubescence 
which has escaped the abrasion which is suffered by the more pro- 
jecting parts.

Silphomorpha speciosa. 
S. late ovata, subtilissime punctata, viridi-purpureo-metallica, nitida, 
subtus nigro-chalybeata ; antennis ferrugineis. 
Hab. 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 ; antennze and palpi 
ferrugmous; eyes pale; head finely corrugated and punctured, deep 
violet, bordered with green in front, the lip black; prothorax very 
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 very distinct from any other in the 
remarkable subfamily to which it belongs, but apparently a true 
Silphomorpha. The purple or dark-violet reflexion (it is difficult 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.
