Mr. C. J. Gahan on Longicorn Coleoptera 
maire’s description of Pachydissus ternatensis fits exactly tlie 
present species, but, as the locality Duke of York Island is 
given in addition to that of Ternate, I am inclined to think 
he has mixed up two species — textor , Pasc., and ampliata , 
described above. 
7. PEolesthes perplexa , sp. n. 
Antennis ( S ) corpore duplo nec sequalibus ; prothorace supra irregu- 
lariter rugoso, spatio parvo transverso levi pone medium. 
Long. 24, lat. 7 mm. 
Hob. Siam (< J . 0. Bowring , Esq.). 
Intergenal groove distinctly bowed backwards. Antennse 
not much more than half as long again as the body. Pro- 
thorax irregularly wrinkled above ; without longitudinal 
impressions and with a small transverse smooth space behind 
the middle of the disk ; sides of the prothorax slightly 
rounded, not at all angulate. Elytra with a rich silky 
pubescence having a coppery-brown lustre, with darker 
patches, which in their turn, when brought into certain lights, 
give bright reflexions ; apices with the sutural angles spinose, 
the outer angles dentate. So closely in colour does the 
unique specimen of this species resemble Siamese specimens 
of induta ^ Newm., that at first sight it looks like a small 
example of the latter. The sculpture of the prothorax, 
however, on which there is not the slightest trace of longi- 
tudinal impressions, is sufficient to distinguish it. In all the 
specimens of induta that I have seen the longitudinal 
impressions are perfectly distinct, and the central smooth 
space is longer than broad. It is possible, however, that the 
unique type of the present species may be an incompletely 
developed or abnormal example of induta. 
8. SEolesthes velutina. 
Pachydissus velutinus , Thoms. 
Pachydissus similis , Gahan, Ann. & Mag. Nat. Hist. ser. 6, vol. v. 
p. 52. 
In the typical example, sent me by M. Rene Oberthiir, the 
derm is of a reddish-brown colour, which gives to the insect 
a lighter appearance than that of the majority of the speci- 
mens which I had included under the specific name similis y 
and which have a dark brown derm. The prothorax in this 
species is slightly rounded, but not angulate at the sides ; it 
carries above two distinct longitudinal impressions, inclosing 
a central smooth space. This space is undivided, except by 
a very short median depression at its anterior termination.
