eall for any particular remark, being yellowish, or brownish-yellow, 
cylindrical grubs, somewhat narrowed behind, with the head, prothorax, 
legs and the plate covering the anus black; the upper surface is set 
with fine granulations and larger black tubercles ; the chief part of the 
following table is taken from Weise (l.c. p. 830). 
I. Mandibles with three teeth, gradually decreasing in 
length, the lower one sometimes obsolete; frontal 
tubercles usually weil defined, larger than the 
circular borders round the base of the antenne ; 
average size larger, 
i. Thorax narrower, about half as broad at base as 
elytra at shoulders, with comparatively broad side 
margins, which, if viewed from above, are visible 
as far as the anterior angles. . 5... . . 
ii. Thorax at base almost as broad as, or evidently 
narrower than, elytra, with narrow side margins, 
which, if viewed from above, are hidden on the 
front half at all events near the anterior angles. 
1. Upper surface of thorax and elytra, if viewed 
sideways, forming a continuous outline; elytra 
only a little broader than the thorax with the 
callosities at shoulders less pronounced. 
A. Elytra gradually widened behind, broadest 
behind middle; third joint of antenne only 
a little longer and narrower than the second ; 
colour usually dark blue; punctuation of

2. Elytra raised and then depressed at base, not 
forming a continuous outline with thorax, if 
viewed sideways, considerably broader at base 
than thorax, with the shoulders and humeral 
callosities more pronounced; colour green or

(coryli, Brit. Car.) 
II. Mandibles with four teeth, of which the two middle 
ones are long and rather large; frontal tubercles 
ill-defined, hardly as large as the circular borders 
round the base of the antennze; size smaller, 
i. Elytra with rather strong rows of punctures on the 
anterior portion of disc, which become feebler 
behind, upper surface thickly alutaceous; suture 
of elytra, as a rule, foveate before apex . . . . 
ii. Elytra with confused and more or Jess shallow 
punctures, not thickly, and exceedingly delicately, 
alutaceous ; suture of elytra, as a rule, not foveate 
before apex.
