Cryptocephalus. | PHYTOPHAGA. 293 
with strong rows of punctures, interstices almost smooth; legs dark, 
metallic, trochanters testaceous. L. 3-41 mm. 
In this and several other species the punctuation of both thorax and 
elytra is stronger in the males than in the females; the latter sex is 
almost universally the largest. 
On young birches, &c.; local, but sometimes common where it occurs; Darenth 
and Birch Woods; Croydon; Woking; Chobham; Hastings; Lords Wood, South- 
ampton; Llangollen; Chartley Moss and Burnt Wood, Staffordshire; Scotland, 
Ross-shire, Glen Affrick, on birch, 1884 (Rev. C. T. Cruttwell). 
C. decemmaculatus, L. (decempunctatus, L.). Head black, with 
the mouth parts and a cordate frontal spot testaceous, distinctly punc- 
tured, eyes at their lower margin reaching a little beyond the anterior 
angles of the thorax, antenne black, with the first five or six joints 
reddish ; thorax rather long, diffusely and distinctly punctured, yellow 
with four black spots which are often confluent and very variable ; 
elytra with rather strong regular rows of punctures, yellow or whitish- 
yeliow with five spots on each (arranged 2, 2, 1), the two behind middle 
being often confluent at suture ; these spots, however, are very variable, 
sometimes the greater part of the elytra being black and sometimes 
yellow ; legs more or less pitchy yellow; under-side black. L. 33-4} mm. 
Male with the fifth ventral segment slightly impressed behind trans- 
versely. 
On the dwarf sallow; rare; taken in June, 1865, in some numbers at Camach- 
gowran, Loch Rannoch, Tay district of Scotland, by Dr. Sharp, Mr. Rye, and Mr. 
Hislop, and in 1866 by Mr. Harris and Mr. W. Garneys at Chartley Moss, Stafford- 
shire; these latter specimens were, I believe, found on birch. 
V. bothnicus, L. This variety has the upper surface entirely black, 
with the cordate frontal spot, and a longitudinal broader or narrower 
band or line on the front of the thorax testaceous; the anterior margin 
of the thorax is also, as a rule, narrowly testaceous; in other points 
it resembles the type. 
Found with the type form ; in Scotland it is the most common form, but Mr. Garneys 
found the ordinary form most common on Chartley Moss, Staffordshire. 
C. morei, L. Black, shining, sometimes with a slight seneous 
reflection, with the basal joints of the antenne, at all events on their 
under-side, the posterior angles of thorax, and a spot at apex and another 
near side margin of elytra yellow or whitish-yellow; head varying in 
colour in the sexes, antenne long, eyes on their lower sides not reaching 
the anterior angles of thorax; thorax very finely punctured; elytra 
with strong and coarse rows of punctures, external interstices some- 
what convex; legs black, partially pitchy or pitchy yellow, some- 
times yellow, anterior femora more or less whitish on their inner margin, 
process of prosteruum yellowish behind, bimucronate. L. 38-5 mm. 
Male with the anterior margin of thorax and an X-shaped mark on 
forehead yellow. 
Female with two yellowish lines near eyes.
