338 ADDENDA 



smaller size, red coxfe, the less black colour on the elytra (these are 

 almost entirely red with a narrow band of black just at base), the much 

 finer punctuation of the head, and the weaker hairs on the rows on the 

 penultimate segQient of the male ; the thorax is also longer in proportion 

 to its breadth than in these two species. 



Ganglbauer mentions L. rijyicola as rare ; Newbery says it does not 

 appear to be rare, and he has seen specimens from Surrey, Hampshire 

 and Carlisle ; these species of Lathrohmm, however, ai-e veiy much 

 mixed in our collections, and require careful working out. 



*Bledius secernendus, Joy (Ent. Mo. Mag. xlvii (2 Ser. xxii), 

 1911, p. 2G9. {B. secerdend'us in error). Black with the apical border 

 and posterior angles of the elytra, broadly brownish testaceous ; mandibles 

 long and slender ; first joint of antennse pitchy, with extreme base and 

 apex testaceous, the other joints obscurely testaceous ; head and thorax 

 dull, aliitaceous, moderately strongly punctured, the latter with a deep 

 central line, and strongly contracted at base ; elytra broader than 

 thorax, about one-third longer than broad, closely and moderately 

 strongly punctured ; hind body shining, finely alutaceous and obsoletely 

 punctured ; femora pitchy, tibipe pitchy-testaceous, tarsi testaceous. 

 L. 3|- mm. 



Probably widely distributed throughout the British Islands ; Dr. 

 Joy has taken it at Tresco, Scilly Isles, and Cloghane co. Kerry. 



This insect is in many of our collections as a dark form of 

 B. arenarius ; from this species it difiers in being larger and thicker 

 with the antennae rather darker ; the head and thorax are more 

 strongly sculptured ; the central line of the thorax is deeper and its 

 sides are more abruptly contracted at base, the basal portion being longer 

 and the posterior angles more prominent ; the elytra, besides being 

 much darker, are more strongly punctured ; the tibife, moreover, are a 

 little more dilated, with the spines longer. 



B. arenarius, Payk, var. minor, Muls. et Rey. (Hist. Nat. Col. 

 Er. Oxypoi'iens, Oxytelins, p. 1!)2). This is a dark form of the typical 

 B. arenarius; it resembles superficially jB. secernewr/«s, Joy, but, apart 

 from colour, difiers in the characters mentioned as distinguishing that 

 t^pecies, the most obvious being the much finer central line of the thorax 

 and the less strongly punctured head. It was introduced as Bledius 

 arenarius, var. fergussoni, by Dr. Joy (Ent. Mo. Mag. xlviii (2 Ser. 

 xxiii), 1912, 44), on a sei'ies taken by Mr. Anderson Eergusson at 

 Knoweside, Ayrshire, on the sandbanks of small streams on the shore, 

 just above high water mark, in company with the type form and 

 B. terebrans. 



Lesteva longelytrata, var. maura, Er. Gen Spec. Staph. 856. 

 In the European catalogue of Heyden Reitter and Weise L. longelytrata 

 is regarded as synonymous with sixteen other insects, all of which have 



* Mons. Bondroit points out in a paper just received (Ann. Soc. Ent. Belgique 

 Ivi, 1912, p. 450) that the serdendus, Joy, is identical with £. subniger, Schneid.
