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. Ehuria longicollis, n. sp. 
Elongata, angustata, fulvo-ochracea ; thorace angustato, 
lateribus acute spinosis (antice hand tuber culatis), disco 
tuberculis duobus elevatis conicis acutis nigris, supra 
haud prof unde punctato-rugoso, rugis undulatis trans- 
versis; elytris fortiter punctatis, vitta prope suturam 
minute rugoso-punctata opaca, tertia parte apicali Isevi, 
subtiliter flavo-pubescentibus cum setis longioribus non- 
nullis ejusdem coloris, maculis eburneis duabus elongatis 
geminatis, una basali, altera apud medium, antice et pos- 
tice nigro-marginatis, apicebispinosis; pedibus elongatis, 
femoribus linearibus, apice nigris, intermediis et posticis 
longe unispinosis.

Eesembles 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 Ehurodacrys from Ehuria. 
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 LinnaBus, which, however, according to the de- 
scription in the Systema Naturae,^^ is destitute of the 
lateral thoracic spines.
