with strong rows of punctures, interstices almost smooth ; legs dark, 

 metallic, trochanters testaceous. L. 3-4} mm. 



In tliis 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.

 and Birch Woods; Croydon ; Woking; Chobhiiin ; Hasting*; Lords Wood, South-

C. decemmaculatus, L. (decempunctatu*, L.). Head black, with 

 the mouth parts and a cordate frontal spot testaceous, distinctly pune- 

 tureJ, eyes at their lower margin reaching a little beyond the anterior 

 angles of the thorax, antennae black, with the first h've or six joints 

 reddish ; thorax ra'her 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- 

 yellow 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. 3^4} 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 Kannoch, Tay district of Scotland, by Dr. Sharp, Mr. R.ve, and Mr. 

 Hislop, and in 1866 by Mr. Harris and Mr. "NV. Garneys at Chartley Moss, Stafford- 

 shire; these latter specimens were, I believe, found on birch. 



V. bothmcus, L. This variety has the upper surface entirely black, 

 with the cordate froiital 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 Cliurtley Moss, Staffordshire. 



C. morael, L. Black, shining, sometimes with a slight eencnu.s 

 reflection, with the basal joints of the antennae, at all events on their 

 under-side, the posterior angles of thorax, and a spot at apex and another 

 nearside margin of elytra yellow or whitish-yellow; head varying in 

 colour in the sexes, antennae long, eyes on their lower sides not reaching 

 the anterior angles of thorax ; thorax very tim-ly punctured ; elyira 

 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 thir inner margin, 

 process of prostenmm yellowish behind, himurronate. L. 3-5 mm.
