290 PHYTOPHAOA. [Oryptocephaltw. 



on Cannock Chase, bat this is the only locality that has been recorded outside the 

 London district. 



C. scxpunctatus, L. Black, shining, with the base of the 

 antennae and, as a rule, the inner side of the anterior tibiae ferruginous, 

 and the forehead, anterior coxse, and the femora at apex, marked with 

 white ; thorax very variable, black with yellow markings or yellow 

 with black markings ; elytra yellow with three large black spots on 

 each, one at shoulder, one in a line with this near suture, and one 

 behind ; these, however, are very variable, and sometimes two only are 

 present, and occasionally the posterior one is divided, so that there are 

 four ; the differences of colour in the thorax appear to be, to a certain 

 extent, sexual; head rather strongly punctured, impressed; thorax 

 short, finely, and not very closely, punctured; elytra confusedly and 

 rather strongly punctured, the punctures being irregular. L. 4-6f mm. 



Male with the fifth segment very large, broadly excavated, with the 

 excavation in the middle divided in two by a transverse rugosity, 

 armed at each side with a hooked spine. 



Female with the pygidium furnished with two distinct tubercles. 



On young hazels and birches in woods, in June, rare ; Darenth Wood ; Cobham ; 

 Hollington, Hastings ; Lords Wood, Southampton (in some numbers 1887, Sbarp 

 and Gorhain) ; Scotland, very rare, on hazels, Solway district j found in two or three 

 places in Dumfriesshire. 



C. bipunctatus, L. ; v. lineola, F. = v. sanguinolentus, Scop. Black, 

 shining, with the elytra very , variable in colour, but in the British 

 specimens apparently confined to one variety, which has the elytra 

 orange or reddish-orange with a broad longitudinal black stripe on each, 

 which is more or less variable in breadth; head rather thickly 

 punctured ; antennae long, with the first five joints reddish or reddish- 

 brown, at all events on the under-side ; thorax smooth and shining, 

 extremely finely punctured, the punctures being only visible under a high 

 magnifying power ; elytra with the rows of punctures variable, stronger 

 and more regular in some specimens than in others, but usually more or 

 less irregular, interstices flat; in punctuation, however, this and the 

 next species form a sort of connecting link between those that precede 

 and those that follow ; the scutellum, margins and suture of elytra, and 

 legs appear to be always black. L. 4-6 mm. 



Male with the fifth ventral segment indistinctly impressed, the 

 impression being nearly smooth. 



On young birches, hazels, oaks, willows, &c. ; in woods, June ; very local, and not 

 common; Darenth and Birch Woods, Chatham, Cobham, Headley Lane (Esher) ; 

 Folkestone ; New Forest ; Portsmouth district ; Bournemouth ; South Wales, Swan- 

 sea, &c. ; Chartley Moss and Burnt Wood, Staffordshire ; Trench Woods ; Yorkshire ; 

 Northumberland and Durham district, rare ; Scotland, very rare, Tay and Forth 

 districts (the latter record is somewhat doubtful). 



C. bigruttatuB, Scop. (Upustulatus, F.). Very closely allied 

 to the preceding, but with the elytra more strongly punctured, and the
