ADEPHAGA. 9 



the average, very slightly smallei-, with the elytra more parallel sided 

 and the thorax less contracted behind ; the shape of the thorax, how- 

 ever, in both species is somewhat variable ; the colour is of a more 

 pronounced black, a slight bluish reflection being present in P.terricola ; 

 the legs are considerably shorter, and the insect is winged ; in the last 

 named species the wings ai-e obsolete. L. 13-15 mm. 



First recorded as taken on sandy soil near the sea, about three 

 miles from Nelson's Pillar, Dublin, by Mr. Stanley AV. Kemp (Ent. Mo. 

 Mag. xxxviii. (2 Ser. xiii.), 210 ; Strood, in a granary (Hudson Beare); 

 Woolwich (Bedwell); Plymouth, in a deep crevice in a tree, blown 

 down by a storm on the previous day (J. H. Keys) ; Isle of Sheppey 

 (J. J. Walker), veiy plentiful in August 1905 in a large heap of sew- 

 age and condemned sacks from the Sheppey Glue and Chemical Works ; 

 Calbourne, Isle of Wight (Pool) ; Southwick near Brighton (Dollman). 



The species has a very wide range and is evidently distributed by 

 commerce ; Mr. Walker has observed it at Gibraltar, Valparaiso 

 (Chili), and Port Adelaide (South Australia), and also in abundance 

 near all the ports in New Zealand which he has visited ; it is a common 

 circum- Mediterranean insect. 



ANCHOMENUS, Erichson. 



A. (Agonum) Viduus, Panz., var. emarginatus, Gyll., Ins. 

 Suec. iv., 450. The insects with projecting shoulders and emarginate 

 base of elytra, standing in our collections as v. mvestus, Duft., must be 

 referred to the above insect. The true v. mcestus is only a deep black 

 form of A. vichms, without any metallic reflection. 



BEMBIDIUM, Latreille. 



B. iricolor. Bedel, Faun. Col. Bass. Seine, i., p. 35. In intro- 

 ducing this species as British, Mr. Newbery (Ent. Mo. Mag. xxis. 

 (2 Ser. iv.), 250), states that it is the insect described by me as B. 

 rijxirium, 01., and that he has seen specimens of it, all taken near 

 brackish water, from Rainham, Plumstead, Plaistow, Sheerness and 

 Southsea, and he further proceeds to reinstate B. lunulatum, Fourc. 

 (1785) = riparium, 01., and auct., as distinct from BedeFs species, and 

 gives the following table : 



I. Elytra with the 7th stria indicated by a i^ow 



of seven or eight punctures . . . B. biguttatum, F. 



II. Elytra with the 7tli stria wanting. 



i. Middle joints of antennae about three 

 times as long as broad ; interstices of 



elytra broader and flatter. L. 4-5. mm. . B. iricolor. Bedel. 

 ii. Middle joints of antennae at most 2h 

 times as long as broad; interstices of elytra 



narrower and more convex. L. 3i mm. B. luxulatum, Fourc. 



= RIPARIUM, 0^.,et auct.
