Cyc,hramus.~\ CLAVICORNIA. 259 



punctured, clothed with thick and fine yellowish pubescence ; colour 

 testaceous or luteous without darker markings ; antenna; with blackish 

 club ; thorax behind about as broad as elytra, with sides strongly 

 rounded ; elytra with very narrow side margins ; legs testaceous. L. 

 3-4 mm. 



On flowers of whitethorn in spring; also in decaying fungi ; rather common and 

 generally distributed in the London and Southern districts ; very common in the 

 Midlands; rarer further north; Northumberland district, rare; Scotland, in fungi, 

 Solway, Clyde, and probably other districts ; Ireland, near Dublin, and probably widely 

 distributed. 



C. fung-icola, Heer. Of a somewhat light ferruginous colour; with 

 a darker shade on each side of the elytra, which is more or less ill-defined, 

 and sometimes disappears altogether; pubescence longer and more 

 scanty and punctuation more diffuse and stronger than in C. luteus ; it 

 is also slightly longer in form, and rather more convex and shining 

 than the latter species. L. 3-4 mm. 



In fungi, especially in autumn ; occasionally by sweeping ; not uncommon and 

 generally distributed throughout England and Wales; Northumberland district, 

 common in fungi in woods ; Scotland, Solway and Moray, and probably other districts ; 

 it is most likely widely distributed in Ireland. 



IPINA. 



As we approach the end of the Mtidulidse, we come upon certain 

 tribes whose position seems somewhat doubtful, but which afford an 

 easy transition from one family to the next ; such tribes are the Ipina 

 and Ehizophagina, which lead into the Trogositidae. Of the Ipina 

 there are three British genera Cryptarcha, Ips, and Pityophagus ; the 

 latter of these three has usually been classed with Ips, but is now rightly 

 separated from it. Some aiithors insert the Cybocephalina between the 

 Cychramina and Ipina, but the 4- jointed tarsi and contractile body 

 of Cyl>oc,eplialus point to a very different position. The Ipina are 

 characterized by having the labrum hidden, instead of free and visible 

 as in the preceding families; the antennae are 11 -jointed, with a 

 somewhat loose 3-jointed club; the prosternum is strongly produced, 

 more so in Cryptarcha than in Ips ; the mentum is very narrow, 

 usually oblong or trapezoidal ; the mandibles in Ips, especially in some 

 exotic species (e.g. Ips Japonica), are very large and strong ; in Cryp- 

 tarcha they are slender and sickle-shaped ; the labial palpi are short in 

 Cryptarcha, longer and less stout in Ips ; the maxillary palpi are some- 

 what slender ; the membranous paraglossse in Ips are very conspicuous ; 

 the British genera may be distinguished as follows : 



L Anterior coxal cavities open behind. 



i. Thorax overlapping base of elytra ; elytra entirely 

 covering abdomen ; body oval, upper surface pubescent. CBYPTABCHA, Shuck*
