behind, and the intermediate space covered with rounded 

 smooth tubercles, two of which, in the middle, are black. 

 Both sexes have the elevated tubercle on the crown 

 which has suggested the name of the genus.

1. Eburia longicoUis, n. sp. 



Elongata, angustata, fulvo-ochracea ; thorace angustato, 

 lateribus acute spinosis (antice haud tubcrculatis), disco 

 tuberculis duobus elevatis conicis acutis nigris, supra 

 haud profunde punctato-rugoso, rug-is undulatis trans- 

 versis; elytris fortiter punctatis^ vitta prope suturam 

 minute rugoso-punctata opaca, tertia parte apicali \sevi, 

 subtiliter liavo-pubescentibus cum setis longioribus non- 

 nullis ejusdem col oris, maculis eburneis duabus elongatis 

 geminatis, una basali, altera apud medium, antice et pos- 

 tice nigi'o-raargiuatis, apicebispinosis; pedibus elongatis, 

 femoribus linearibus, apice nigris, intermediis et posticis 

 longe unispinosis. 



Long. 10 lin. ? . 



Resembles the species of Ehurodacrys in form, and in 

 the elongate femora, but has no trace of the groove along 

 the third and fourth antennal joints, which is the chief 

 character that distinguishes Ebwodacryu from Eburia. 

 The sculpture of the thorax consists of large shallow 

 punctures, forming on the disc short very irregular trans- 

 verse furrows. The elytra have the basal two-thirds 

 thickly covered with circular punctures or foveoles, but 

 near the suture these are replaced by a minute sculpture, 

 rendering that part opaque, the apical third is smooth, or 

 with very slight punctuation ; the pubescence is fine, and 

 of a golden yellow, with a few scattered longish bristles 

 of the same colour ; the apex only is glossy ; the ivory 

 spots are somewhat elongate, and the pairs of which each 

 consist do not differ notably in relative length. 



The Species is evidently allied to the true E. 4-macu- 

 lata of Linnaeus, which, however, according to the de- 

 scription in the " Systema Naturae," is destitute of the 

 lateral thoracic spiuos.
