22 .CLAVICORNIA. [Liodes. 



antennae brownish with the club, except apex, darker ; thorax extremely 

 finely and scarcely visibly punctured with margins lighter than disc ; 

 posterior angles distinct ; elytra somewhat acuminate behind, with 

 irregular rows of rather coarse punctures, and the interstices between 

 these rather coarsely punctured, so that the whole surface almost appears 

 to be evenly punctured ; the spaces between the punctures are very finely 

 punctured or cross- striated ; the sutural stria almost reaches base of 

 elytra ; under-side and legs brown-red. L. 3 mm. 



Male with the three first joints of the anterior tarsi rather strongly 

 dilated. 



Scotland, Highlands, under bark of fir ; local ; Tay, Dee, and Moray districts. Dr. 

 Sharp has found it in some numbers at Bannoch. 



It. orbicularis, Herbst. A small, short oval, somewhat globose 

 species, pitch-black or darker or lighter pitch-brown, antennae reddish 

 with the club, except apical joint, blackish ; head finely punctured, with 

 the mouth-parts and often a spot on forehead reddish ; thorax very finely 

 and hardly visibly punctured, with the margins rather broadly lighter, 

 posterior angles distinct, elytra with fine and somewhat indistinct rows 

 of large punctures, interstices very finely punctured, sutural stria deep 

 and reaching to about middle ; under-side and legs rather bright reddish 

 or brownish-red. L. 2-2i mm. 



Male with the anterior tarsi feebly dilated, posterior trochanters pro- 

 jecting in a small point, posterior femora furnished with a small tooth 

 in middle. 



In dry and powdery fungoid growth on old trees ; rare; Darenth Wood, Ashstead, 

 Claygate, Strood, Caterham, Cobhnm Park; Hastings; Lewes ; New Forest; Can- 

 nock Chase ; Delamere Forest, Cheshire ; Nocton, near Lincoln ; Ripon ; Northumber- 

 land district, Gosf orth, rare ; not recorded from Scotland. 



CYRTUSA, Erichson. 



This genus contains about half a dozen species from Europe and North 

 America ; they are very small insects of a lighter or darker testaceous or 

 reddish-brown colour, and much resemble the smallest species of Aniso- 

 toma, from which they differ in having the antennae apparently 10-jointed 

 and the club 4-jointed, the second joint of the club being very minute 

 and scarcely visible even under a high power ; it differs further from 

 this latter genus in not having the mesosternum carinate ; from Colenis it 

 may be known by the formation of the club of the antennae and the fact 

 that the tarsi are 5- 5- 4-jointed. 



I. Form larger, less elongate, and more convex ; posterior 

 tibira gradually widened to apex ; posterior angles of 



thorax rectangular C. MINUTA, Ahr. 



I. Form smaller, more elongate, and less convex ; pos- 

 terior tibiae abruptly widened at apex ; posterior angles 

 of thorax bluut (but not rounded) C. PATTXILLA, Schmidt.
