254 Mr. C. J. Gaban oti Longicorn Coleoptera 



m aire's description of Pacliydissus ternatensis fits exactly the 

 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 ampliataj 

 described above. 



7. /Eolesthes perplexaj sp. n. 



Antennis ( c? ) corpore duplo nee sequalibus ; prothorace supra irregu- 



lariter rugoso, spatio parvo transverse levi pone medium. 

 Long. 24, lat. 7 mm. 



Hob. Siam (/. C. 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 dai'ker 

 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. ^olesthes velutina. 



Pachydissus vclutinus, Thorns. 



Pacln/dissus similis, Galian, Ann. & Mag. Nat. Hist, ser. 6, vol. v. 

 p. 52. 



In the typical example, sent me by M. Ren(3 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^ 

 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.
