Description of a new Sumatran species of the genus Aulacochilus (Coleoptera: Erotylidae)

Allied to Aul. Doriae Bedel and resembling that species, but at once distinguished by the number of the fulvous spots on the elytra, these being four in number in Doriae and six in the new species. Length varying between 10,5 mm. and 7,5 mm. — Black; head and pronotum with a faint bronze hue; each elytron provided with three large fulvous yellow spots: one at the base, one at the middle, the third at a short distance from the apex. The spots are roundish or slightly transverse, neither of them touching the margin or suture, except the basal one which touches the basal margin of the elytra; this spot is minutely excised in front at the shoulder; the central spot is somewhat farther removed from the lateral margin than both the other spots.
