Synchita.] CLAVICORNIA. 191 



SYNCHITA, Hellw. (Ditoma, H. E. W.). 



This genus contains about fifteen species, which are very widely 

 distributed, representatives being recorded from North and South 

 America, Africa, the Antilles, &c. ; three occur in Europe, of which two 

 have for some time been regarded as British ; Dr. Sharp, however (Ent. 

 Monthly Mag. xxii. 44), shows conclusively that we do not possess 

 S. mediolanensis, which was introduced with considerable hesitation by 

 Mr. Eye in the Entomologists' Annual for 1868, p. 65. All our 

 specimens must therefore be referred to S.juglandis, which appears to 

 vary considerably both as regards colour and size. 



S. juglandis, F. (v. obscurer, Eedt.). Oblong, fuscous, with the 

 thorax sometimes darker than the elytra, dull ; the colour, however, is 

 variable ; upper surface rather depressed ; antennae brownish-red, with 

 the club lighter, apparently solid ; head much narrower than thorax, 

 thickly and finely rugose ; thorax a little narrower than elytra, broader 

 than long, margined, with all the angles blunt, very thickly and rugosely 

 punctured ; elytra with regular rows of strong crenulate punctures, and 

 the interstices finely wrinkled ; on each row of punctures and on each 

 interstice there is a row of fine grey outstanding setae ; the colour of 

 the elytra is usually fuscous, with a lighter spot at each shoulder, 

 but sometimes it is unicolorous testaceous-brown ; legs ferruginous. 

 L. 2-4f mm. 



Under bark of deciduous trees, in old stumps, &c. ; very rare ; New Forest (taken, 

 by Turner, and lately in some numbers by Mr. Gorharn and Dr. Sharp); Stephens 

 records it from the London district, and Halidny from near Belfast ; I believe that 

 Mr. Crotch is said to have taken it at Thetford, near Merton, Surrey. 



CICONES, Curtis. 



In the Munich catalogue four species only are enumerated under this 

 genus, two from Europe, one from Tahiti, and one from Ceylon ; further 

 species, however, have been found in Ceylon, and Dr. Sharp has lately 

 described two from Japan, so that the genus is probably a numerous and 

 widely distributed one ; it differs from Ditoma by its solid club, and 

 from Synchita by having distinct grooves for the reception of the 

 antenna?. 



C. varieg-atus, Hellw. (carpini, Curt.). Oblong, rather broad, 

 fuscous, sometimes nearly black, clothed with more or less distinct short 

 yellowish and brownish hairs, elytra irregularly variegated with yellowish 

 bands ; antennae and legs reddish ; head much narrower than thorax ; 

 thorax about as broad as elytra, rather strongly transverse, anterior angles 

 produced, posterior angles almost right angles ; disc uneven ; elytra with 

 rows of punctures, which are somewhat irregular between the interstices, 

 alternate interstices slightly raised ; legs short. L. 3 mm.
