ZEUGOPHORA, Kunze. 
This genus contains about twenty species, of which four are found in 
Europe, and the remainder have been described from North America, 
the Amur district, Assam, and Ceylon; they are characterized by having 
the upper surface sparingly pubescent, the eyes slightly emarginate, and 
the thorax furnished at sides with a strong, sharp tubercle; the last 
joint of the tarsi is short, and the tarsal claws are armed with a blunt 
tooth; the thorax is much narrower than the elytra, which are oblong, 
subparallel, and very strongly punctured. 
I. Elytra dark. 
i. Head entirely reddish-yellow. . . . . . . . 4Z. SUBSPINOSA, F. 
ii. Forehead and vertex of head black . . . . . Z, FLAvicoLuts, Marsh. 
Il. Upper surface entirely testaceous . . . . . . Z, TURNERI, Power. 
Z. subspinosa, |. Black, with the first four joints of the antenne, 
the head, thorax, and legs red; head rather strongly punctured, eyes 
prominent, antenne short; thorax strongly punctured, witha large blunt 
lateral tubercle on each side, much narrower at base than elytra; 
elytra subparallel, strongly margined, very coarsely punctured ; legs 
moderately stout ; the mesosternum is sometimes red. L. 3 mm. 
On young aspens, in woods, rather local, but not uncommon; London district, 
generally distributed; Whitstable; Hastings; Hampshire; Bewdley Forest ; 
Knowle ; Wicken Fen; Weston, Oxfordshire ; Bretby, near Repton; Chat Moss; 
Langworth Wood, Lincoln; Manchester and Liverpool districts; it has not been re- 
corded from the extreme northern counties of England, or from Scotland. 
Z. flavicollis, Marsh. Very like the preceding, from which it may 
be at once known by the colour of the head, which has the part before the 
eyes yellow and the remainder black; the lateral tubercles of the 
thorax are larger and spiniform, and the posterior femora are fuscous ; 
the elytra also are more sparingly punctured. L. 23-35 mm. 
In woods; very rare; Bexley and Ashford (Kent); Kimpton, Hants; Seal Wood, 
Leicestershire (J. T. Harris) ; Manchester district; one specimen from H. Adams, 
Kendal (Power). 
Z. Turneri, Power (rufo-testacea, Kr.). Rather more elongate than 
either of the preceding species, and easily distinguished by its colour, which 
is entirely rufo-testaceous, with the eyes, mesosternum, metasternum, and 
abdomen black ; in general form it much resembles Z. subspinosa, but 
the head is more closely and deeply punctured, and not so much con- 
tracted behind the eyes, which are less prominent, and the thorax is
