AULACOCHILUS STOLZII. 175 
NOTE XXXI. 
DESCRIPTION OF A NEW SUMATRAN SPECIES OF 
THE GENUS AULACOCHILUS 
(Coleoptera: Erotylidae) 
BY 
C. RITSEMA Cz. 
Aulacochilus Stolzit, sp. n. 
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. 
The head is smaller than that of Doriae, subshining 
though very distinctly and rather densely punctured; the 
punctures on the clypeus are smaller and closer together. 
The prothorax is very transverse, very much narrowing 
to the front in regularly curved lines ; the sides are depressed, 
their outer edge finely raised. The pronotum is shining, 
very finely punctured all over and with a group of some
