Aglenus.] CLAVICORNIA. 187 



a small reddish-brown cylindrical insect, and is characterized by the 

 absence of eyes. 



A. brunneus, Gyll. Short, cylindrical, ferruginous or reddish- 

 testaceous ; head large, almost as broad as thorax, distinctly punctured ; 

 antennae short, 11-jointed, with club 3-jointed ; thorax about as 

 long as or a little longer than broad, truncate in front and behind, 

 rather thickly punctured ; elytra scarcely longer than head and thorax 

 taken together, somewhat ovate, obsoletely punctured behind, more 

 plainly towards base ; under-side of all the segments of thorax thickly 

 and deeply punctured ; legs short, reddish- testaceous. L. 1^-2 mm. 



In manure-heaps, tan-pits, refuse of corn-bins, old props in cellars, hot-beds, &c. ; 

 local ; Esher ; Ashford, Kent; Cowley; Birdbrook, Essex ; Forest Hill; Edgbaston ; 

 I believe also that it has occurred in Gloucestershire; it is probably often overlooked. 



COXiYDXUlK, Fabricius. 



A few species are included in this genus from North and Central 

 America, Senegal, &c. ; two occur in Europe, one of which is among the 

 very rarest of our British insects ; it is found only in the New Forest, 

 and appears to be parasitic in the burrows of Platypus cylindrus. 



C. elong-atum, F. Linear, very long and narrow, shining black ; 

 antennae rather short, brownish-red, with a strong 3-jointed club, 

 maxillary palpi with the last joint somewhat securiform ; head diffusely 

 and sparingly punctured ; thorax much longer than broad, very slightly 

 narrowed towards base, rather sparingly and finely but distinctly punc- 

 tured, with a strong and deep complete central furrow, and a smaller one 

 on each side, which are somewhat abbreviated in front and behind ; 

 elytra with the suture and four lines on each side raised, the latter more 

 stiongly than the former, with the interstices somewhat rugose and each 

 furnished with two rows of punctures ; legs brownish-red. L. 4-6 mm. 



Under bark, and in old trees, in the burrows of wood-feeding beetles ; very rare ; 

 New Forest (Turner, Champion, &c.). 



My single specimen, which is labelled " Turner, 1862," has the head 

 and thorax black and the elytra reddish- brown. 



TEREDUS, Shuckhard. 



Two European species and one from Ceylon are contained in this 

 genus ; one of these is found in Britain ; they are distinguished by their 

 long cylindrical form, and the 2-jointed club of the antennas. 



T. nitidus, F. (cyHndncus, 01.). Long, narrow, and cylindrical, 

 shining black ; antennae ferruginous ; thorax about double as long as 

 broad, as broad in front as elytra, slightly narrowed to base, with all the 

 angles blunt, thickly and finely punctured ; elytra parallel, rounded
