Hyliota of the Coleopterous family Cucujidtz. 599 



and fourth joints of the antennas are of equal length, 

 whereas in the other species the fourth joint is about 

 equal to the second and third together. From H. sjpini- 

 collis, Guer., the new species differs by its non-thickened 

 antennas and the presence of a tubercle on the middle 

 tibiae. 



I may note here that the species referred to by Dr. 

 Heller in his table of the Indo- Malayan Hyliotte as dent- 

 iculatus, Smith (an insect I have already referred to H. 

 dubia, Fabr.), and earlier as " denticollis, Sm.," is evidently 

 H. lucia, Pascoe. 



H. siamensis, sp. n. 



Testacea, valde depressa, setis fulvis brevissimis undique vestita, 

 capite prothoraceque grosse punctatis, medio subnitidis ; illo antice 

 longitudinaliter carinato, carina brevissima, inter pilorum aureorum 

 fascicules duos posita, oculis prominentibus ; prothorace fere quad- 

 rato, lateribus subaequaliter dentatis, disco utrinque carinato ; elytris 

 extus valde carinatis, punctato-striatis, interstitiis alternatis laevis- 

 sime carinatis ; pedibus brevissimis simplicibus ; antennarum arti- 

 culo quarto ad duos prsecedentes conjunctos fere sequali, tertio quam 

 secundo duplo longiore. Long. 5*5 mm. 



Hal. Si am (Bo wring). 



This species is exceedingly like H. costicollis, Reitt., 

 with the type of which I have been able through M. 

 Oberthiir's kindness to compare it. It is rather smaller 

 and the head and thorax are visibly punctured and not 

 entirely opaque, while the two strong carinas on the disc 

 of each elytron are only feebly indicated in this, as in H. 

 serricollis, Cand., which however is much more elongate. 

 If M. Grouvelle is right in regarding the possession of 

 tufts of hairs upon the front of the head as a sexual 

 character, the two specimens from which my description 

 is compiled are males. 



H. indica, sp. n. 



Testacea, valde depressa, setis erectis brevissimis undique vestita ; 

 capite prothoraceque crebre punctatis, illius medio antice et postice 

 subtiliter elevato ; prothorace antice, postice et lateraliter vage im- 

 presso, quam longitudine paulo latiore, basin versus angustato, 

 lateribus rectis,vixperspicne dentatis, dentibus duobus anticis minus 

 minutis, disco non carinato ; scutello valde transverso, crebre
