Thalycra.'] CLAVICORNIA. 239 



sweeping ; according to Erichson its probable habitat is underground, 

 as the structure of the legs seems to indicate, and he is of opinion that 

 it comes out on hot summer evenings on grass and low vegetation ; the 

 species somewhat resembles externally Cychramus fungicola, but may 

 easily be known by its compact club, and by the fact that the thorax 

 fits closely to the elytra and does not cover their base. 



T. sericea, Sturm, (fervida, 01. ; Strongylus fervidus, Steph.). 

 Bright rust-red, shining, ovate, moderately convex, clothed with short 

 silky pubescence, apex of elytra sometimes darker ; antennae red, with 

 dark club which is very round and compact, first joint enlarged, almost 

 semicircular ; thorax fully as broad at base as elytra, rounded at sides 

 and narrowed in front, anterior margin emarginate, posterior margin 

 feebly bisinuate, posterior angles almost right angles but somewhat blunt, 

 upper surface strongly punctured ; elytra strongly punctured at base, 

 more feebly at apex ; elytra and thorax closely fringed with short white 

 hairs ; legs red, anterior tibue simple, posterior pairs armed with spines 

 on their external margins. L. 3-4 mm. 



At the exuding sap of Cossws-infected trees; occasionally by evening sweeping; 

 rare ; Birch Wood, Shirley, Ripley, Esher, Surbiton, Mickleham, Loughton, Bromley, 

 Tilgate Forest; Eythorne ; Balcombe (Sussex); Bournemouth; Knowle, near 

 Birmingham; Scotland, very rare, Moray district; it is the same as the Strongylus 

 fervidus of Stephens, and according to him occurs in fungi. 



POCADXUS, Erichson. 



This genus contains eight or nine species, two of which are found in 

 Europe, and the others have been described from North, Central, and 

 South America, India, and Ceylon ; the species bear a sort of superficial 

 resemblance to Thalycra and Cychramus, but may be distinguished 

 from the first by the regular rows of punctures on the elytra, which are 

 separated by regular rows of yellow hairs, and from the latter by the 

 compact round club of the antennae (the club in Cychramus being 

 elongate), and the fact that the anterior tibiae are produced into a strong 

 point at apex. 



P. ferrug-ineus, F. Oval, convex, shining, of a reddish-brown 

 colour, apex of elytra sometimes darker ; antennae very short, light red, 

 with dark club, which is very compact ; thorax very short in comparison 

 with elytra, narrowed in front, posterior angles sharp, with narrow, 

 though distinct, margins, rather diffusely and obscurely punctured ; 

 elytra with punctuation and pubescence as above described ; legs light 

 red, with all the tibiae produced into a point at apex. L. 3-4 mm. 



In decaying fungi, especially Lycoperdons ; local but rather widely distributed in 

 the London, Southern, and Midland districts; rarer further north ; Northumberland 

 district, rare ; Scotland, rare, Tweed, Forth, and Moray districts.
